Sewing Machine Bobbin Problems and Solutions What to check when winding a bobbin 1. Do you use a bobbin specific for your sewing machine? 2. Did you make sure that the thread is not going to unwind when you cut the thread tail? 3. Is the thread tangled on the spool pin? 4. Is the thread winding unevenly? 5. Is the thread caught on the notch of the spool? 6. Did you hold the thread tail in the beginning of winding the thread? ageberry.com What to check when your bobbin winder doesn't work 1. Verify that you are using the correct size bobbins. 2. Check if you aligned the groove in the bobbin with the spring on the bobbin winder shaft and pressed down on the bobbin until it snapped into place. 3. Check if the thread is passed through the bobbin winding guide correctly. 4. Check if there are scratches or other defects on the bobbin. Replace the bobbin if in doubt. 5. Make sure that the bobbin winder is engaged. 6. Check under the small bobbin pin. Is there thread wrapped around the pin? 7. Something could be loose or broken inside, some dirt or particles that have made the winder stuck with friction. ageberry.com Sewing machine not picking up bobbin thread 1. First, check if you used a bobbin that has been designed for your machine. 2. Make sure the bobbin-winding spindle has been pushed back to initial position for sewing after the bobbin was winded. 3. Verify that your needle is set in the slot properly, all the way up into the needle shaft, with the flat side of the needle toward the rear of the machine. Or maybe your needle is too big, too small, or defective? Try to change the needle for a new one. 4. Be sure the bobbin thread is reasonably long (about 3-4 inches). 5. The bobbin thread & top thread need to be pulled to the back before starting sewing. 6. Make sure your bobbin is inserted correctly (couterclockwise) 7. Check the bobbin case under the bobbin and remove any accumulated lint and dirt. ageberry.com Thread bunching up, looping and tangling. Page 1 1. Your upper thread tension may be too loose if you are getting thread bunching under your fabric. So check if the thread is properly going through the tension disks. If everything is right try tightening the upper tension to solve the problem. 2. Verify if your needle is threaded correctly. Does the thread go through the thread guide? Through the tension disks? Rethread the machine to see if it solves your problem. 3. Verify if your bobbin is threaded and inserted correctly. 4. Birdnesting may happen also if you are using different types of threads in the needle and in the bobbin. It's perfectly normal to do so but if the difference in thread weight and fiber is too big it may be the reason for thread bunching. ageberry.com Thread bunching up, looping and tangling. Page 3 1. Your Feed Dogs may be down: if your fabric is not feeding through your machine, you will get bunched up thread under your fabric. Make sure that your feed dogs are up if you have lowered them recently for other purposes. 2. Your thread tails are too short: if the thread tails coming out of your bobbin and needle are less than two inches long, they may get pulled into your sewing machine when you begin to sew, causing thread bunching. To avoid this problem, you can either hold the thread ends until you have sewn a couple of stitches or always make sure that your thread tails are at least three inches long before you begin sewing. 3. You’re not using a spool cap: spool caps keep your spool of thread from getting out of control. If you don’t use one, your thread spool may spin too quickly. So, always use a spool cap, especially if you have a horizontal spool pin to avoid bunching or looping thread. ageberry.com Thread bunching up, looping and tangling. Page 2 1. Use good quality thread. If the thread has knots and loose fibers coming out change the thread. 2. Don’t sew with the presser foot up. Everybody does this from time to time especially with heavy fabric. Make sure to always put your presser foot down to avoid bunching. 3. Make sure you are using the proper needle for the fabric you are using. Also, double-check that the needle is not bent. 4. Frequent cleaning and dusting will prevent many problems. Make sure to dust underneath the throat plate, in the bobbin case, and along the thread path. ageberry.com Bobbin keeps popping out 1. Make sure you are using the correct bobbin for your machine. 2. Check if the bobbin case is properly/securely placed. Sometimes this happens after you've taken it all apart to clean or clear a jam. 3. Remove the plastic bobbin case and see if it has any rough chips or needle holes in it. If it does replace it. 4. Verify if the bobbin has been wound correctly and not too tight. 5. Check the upper thread tension: if it's too tight then the thread will loop around the shuttle case and pop it off. ageberry.com Bobbin winds unevenly 1. Use a correct bobbin for your model of a sewing machine. 2. If the thread gets caught or tangled while you are winding the bobbin, the bobbin could be wound unevenly. 3. When winding the bobbin, feed the thread through the winding tension disks so the thread has proper tension and the threads lie next to each other. 4. If everything is correct but you still have a glob in the center or tapered ends you can use your finger to help the bobbin fill evenly. ageberry.com MAY YOUR BOBBIN ALWAYS BE FULL ageberry.com.

Typically, these on the bobbin case. threads, yarns, and cords are too large to fit through the eye of the sewing machine needle. So, in order to achieve a “stitched 5. Remember the rule of tension adjustment --“Righty, Tighty -- look”, you sew with the heavy decorative thread wound onto a Lefty, Loosey” bobbin and placed in the bobbin case of the machine. 6. Use a “construction quality” thread on the “topside” of your machine, as the needle tension will usually be increased. Think of the top thread as literally pulling the “bobbin yarn” into place to form the stitch pattern. 7. Bobbins can be wound by hand or by machine. Whenever possible, wind the bobbin using the bobbin winder mechanism on the machine. This will properly tension the “bobbin yarn” for a better stitch quality. 8. Bobbinwork can be sewn with the Feed dogs up or down. If stitching freemotion, a layer of additional stabilizer or the use of a machine embroidery hoop may be necessary. 9. Select the proper presser foot for the particular bobbinwork YARNS AND THREADS SUITABLE FOR BOBBINWORK technique being sewn. When working with the heavier “bobbin yarns”, the stitches produced will be thicker. Consider selecting • Yarns (thinner types, often a foot with a large indentation underneath it, such as Foot used for knitting machines) #20/#20C.This foot will ride over the stitching much better.

  • Tailoring Series TECHNIQUES for TAILORING UNDERLINING a TAILORED GARMENT—Underlining Is a Second Layer of Fabric. It Is Cut By
    tailoring series TECHNIQUES FOR TAILORING UNDERLINING A TAILORED GARMENT—Underlining is a second layer of fabric. It is cut by the garment pattern pieces and staystitched to the wrong side of the corresponding outer sections before any seams are joined. The two layers are then handled as one. As a general guide, most suit jackets and coats look more pro- fessional when underlined. Underlining is especially recommended for lightweight wool materials, loosely woven materials and light- colored materials. For additional information on selecting fabrics for underlining and applying the underlining, see Lining a Shirt 01' Dress HE 72, N. C. Agricultural Extension Service. STAYSTITCHING—Staystitch all outer garment pieces before construction begins. If garment is underlined, stays-titching is done when the two layers of fabric are sewn together. Staystitch 1/3 in. outside seamline (on the seam allowance). Stay- stitch “ with matching cotton thread on all curved *areas that may stretch during construction such as necklines, side seams, shoulder seams, armholes, and side seams of skirt. Use directional stitching always to prevent stretching of fabric and to prevent one layer of fabric from riding. The direction to stitch is indicated by small arrows on the pattern on the seamlines. INTERFACINGS—Select a high quality hair canvas for the front and collar of coats and jackets. The percentage of wool indicates the quality—the higher the wool content of the canvas the better the quality. Since a high percentage of wool makes the hair canvas fairly dark in color, it cannot be used successfully under light-colored fabrics. In these cases use an interfacing lighter in color and lower in wool content.

DIRECTIONS FOR USENG THE 11112er Y rr+peoved Parr,Iiy t4achile. To Oil the Machine. Be sure that every part is clean before you commence to sew. If the machine runs hard at any time, IT IS CERTAIN that someplace has not been oiled. Oil holes will be found for all bearings which cannot be reached without them. Each place requiring oil is indicated by an arrow head in the cuts on the opposite page. The shuttle should be oiled sparingly, but often, if the machine is in constant use ; always be careful to use no more oil than is needed, a single drop being sufficient at any point. If the machine runs hard after standing idle for some time, use a little kero- sene oil or benzine on the wearing points, run rapidly, zvi~e clean, and then oil with the BEST slerni oil, which should always be used. To make sure of getting good oil, buy it at at any of the Company's offices or from its authorized representatives. The genuine oil is put up in bottles which have The Singer Manufacturing Company's " trade-mark " blown in their panel, and bear the Company's label.

  • Powerhouse Museum Lace Collection: Glossary of Terms Used in the Documentation – Blue Files and Collection Notebooks
    Book Appendix Glossary 12-02 Powerhouse Museum Lace Collection: Glossary of terms used in the documentation – Blue files and collection notebooks. Rosemary Shepherd: 1983 to 2003 The following references were used in the documentation. For needle laces: Therese de Dillmont, The Complete Encyclopaedia of Needlework, Running Press reprint, Philadelphia, 1971 For bobbin laces: Bridget M Cook and Geraldine Stott, The Book of Bobbin Lace Stitches, A H & A W Reed, Sydney, 1980 The principal historical reference: Santina Levey, Lace a History, Victoria and Albert Museum and W H Maney, Leeds, 1983 In compiling the glossary reference was also made to Alexandra Stillwell’s Illustrated dictionary of lacemaking, Cassell, London 1996 General lace and lacemaking terms A border, flounce or edging is a length of lace with one shaped edge (headside) and one straight edge (footside). The headside shaping may be as insignificant as a straight or undulating line of picots, or as pronounced as deep ‘van Dyke’ scallops. ‘Border’ is used for laces to 100mm and ‘flounce’ for laces wider than 100 mm and these are the terms used in the documentation of the Powerhouse collection. The term ‘lace edging’ is often used elsewhere instead of border, for very narrow laces. An insertion is usually a length of lace with two straight edges (footsides) which are stitched directly onto the mounting fabric, the fabric then being cut away behind the lace. Ocasionally lace insertions are shaped (for example, square or triangular motifs for use on household linen) in which case they are entirely enclosed by a footside. See also ‘panel’ and ‘engrelure’ A lace panel is usually has finished edges, enclosing a specially designed motif.

  • Tips for Minimizing Embroidery Interruptions
    TECHNICAL BULLETIN TIPS FOR MINIMIZING EMBROIDERY INTERRUPTIONS Sewing interruptions can be caused by many factors, however the most common causes include the following: • Needle Thread Breakage or Pull-out – not picking up at the beginning of a stitch pattern • Bobbin Thread Run-out or Thread Pick-Up – not picking up at the beginning of a stitch pattern • Improper Thread Trimming • Thread break detector stoppage In order to minimize interruptions during the stitching of complex embroidery patterns, the following vital elements must work together during the embroidery process. These vital elements include: • Proper Digitizing for the fabric and pattern being sewn • Proper Embroidery Machine Maintenance and Settings • Correct Backings and/or Toppings for the Application • Proper Needle Type and Size • Quality Embroidery Threads We will look at each of these elements and discuss potential causes for excessive sewing interruptions. A. INTERRUPTIONS DUE TO NEEDLE THREAD BREAK Digitizing Causes: • Improper cornering with too many stitches in the same location • Not using appropriate underlay stitches that help minimize flagging during the rest of the stitch pattern • Density properties too high within designs that layer many colors of thread • Not using Tie-In Stitches at beginning of thread changes • Not using Short Stitches at the end of a stitching cycle Digitizing Solutions: • Try to minimize the stitch density at any one point. TECHNICAL BULLETIN • Reduce density properties as you build up layers of embroidery • On lettering, use your “short-stitch” function • Use appropriate underlay stitches that help minimize flagging • Use slower speed “Tie-In” Stitches at beginning of thread changes • Use slower speed “Tie-Off” Stitches at the end of a stitching cycle.
