  • MAINTENANCE, ADJUSTMENT and REPAIR of INDUSTRIAL SEWING MACHINES by WAYNE SNYDER, MASTER RIGGER US ACADEMY of PARACHUTE RIGGING
    MAINTENANCE, ADJUSTMENT AND REPAIR OF INDUSTRIAL SEWING MACHINES by WAYNE SNYDER, MASTER RIGGER US ACADEMY of PARACHUTE RIGGING Presented at the PIA INTERNATIONAL PARACHUTE SYMPOSIUM RENO, NEVADA February 2007 MAINTENANCE, ADJUSTMENT AND REPAIR OF INDUSTRIAL SEWING MACHINES PREMISE: You know how to sew and you are working with an “E” thread lock stitch sewing machine and it was sewing and now it’s gone bad. You probably just changed something – 98% of the time just go back and inspect and correct what you just did and you will be back in business. COMMON CASE SCENARIOS: A. Bobbin change B. Top thread change C. Jam D. Broken needle and/or changed needle Before we get into these specific areas, let’s go back and remember the basic way the machines work. All lock stitch machines make the same stitch. 301, 304, or 308: these are just lock stitch machines. “THE FLOW ACTION” • The needle does down • The needle goes below path of hook (Figure 1) • Needle bottoms out (B.D.C.) • Needle comes up (3/32 inch - common measurement), loop forms on hook side of needle (non-long groove side of the needle) (Figure 2) • Hook picks up top thread loop and carries it around bobbin case. (Figure 3) • Hook drops top thread off (Figure 4) • Thread take-up arm takes out slack and sets stitch in goods. (Figure 5) • Think of the bobbin thread as a long straight rod with the top thread spiraled around it. Sew a piece of paper with two different color threads – rip paper to remove it and there is your example.

  • Cleaning and Oiling a Rotary Hook System
    Oiling the rotary hook system Page 1 of 2 Cleaning and oiling a rotary hook system. It is very important that YOU as the customer knows how to correctly oil your hook system. It is important for you oil the hook on a regular bases. Remove the needle and the bobbin case. Unplug your sewing machine! Remove your stitchplate and clean between the feed dog rows like it shows you in the picture below. Please refer to your manual if you do not remember how to take off the stitch plate. The picture below shows you how the hook looks like when your needle is in the highest position. If you see a lot of "dirt" around there, clean it out with a brush before you go to the next step. http://berninapfaff.com/helpfiles/oiling_cleaning_main/rotary_hook/oiling_rotary_hook.html 12/1/2009 Oiling the rotary hook system Page 2 of 2 Now turn your handwheel in sewing direction until you see the picture below. As you will turn you will see an opening between the two points. (the two red arrows pointing at it). In some machines both points are maybe metal or like you see here, one is maybe "plastic". When the ring behind (the green arrow is pointing at the spot) is showing, stop turning the handwheel. That is where you put a drop of oil. The ring may have a small cut out like in this picture, or it might be solid. Home As always Email me if you need more help or have any questions.

  • Technologies of Forming the Lockstitch Type 301 and Their Demerits
    TECHNOLOGIES OF FORMING THE LOCKSTITCH TYPE 301 AND THEIR DEMERITS The author of the article, Ph.D. Zarif Sharifovich Tadjibaev, Director of ZARIF Sewing Machine Co., Ltd. (www.zarif.uz), who in 1994 invented the world's first ZARIF technology of forming the double thread chain stitch of the new type 401 using a rotary looper, for which US Patent No. 6095069 was issued in 2000. Also, Ph.D. Zarif Sharifovich Tadjibaev in 2016 and 2019, through the improvement of ZARIF double thread chain stitch technology from 1994, invented new ZARIF double thread chain stitch technologies, which are the most advanced for sewing various materials and automation of sewing. The structure of lockstitch type 301. As know the lockstitch type 301 consists of the top thread 1 (needle thread) and the bottom thread 2 (hook thread) (see Fig.1). Fig.1. To get the lockstitch type 301 structure for joining material 3, need to perform the following actions on the threads 1 and 2 (see Fig.1): 1. The loop from the top thread 1 is conducted through the material 3 (in all stitch forming technology this process is carried out using a needle). 2. One branch of the bottom thread 2 is passed through the loop of the top thread 1. 3. The loop of the top thread 1 is tightened to the middle of the material 3, taking one branch of the bottom thread 2 to the middle of the material 3. 4. Material 3 is feed to the stitch length and, all actions over the threads 1 and 2 are repeated.
