Artists’ works are portrayed on it. Of course, we mean paper; the medium that has evolved to reflect its own poetry, becoming an opportunity for pure innovation and unlimited creativity. Through the years, a melding of ancient craft and enlightened technology occurred, creating new practices and opening new horizons for expression in paper. When we trace its history, we find insight into man’s relentless imagination and creativity. Today, this convergence of ancient and modern continues and paper emerges with not only greater variety but a renewed appreciation of quality. To some, fine paper is the space that translates what is conceived in the mind to what is authentic. To others, having access to the right paper represents abundant possibility and profitability. The very selection of paper now becomes an adventure, realizing how the end result will vary based upon choice. Today, as in the years past, Legion Paper continues to source the finest papermakers around the globe, respecting the skill of the artisan and the unique attributes of the finished product. As we head into the future, Legion remains steadfast in its commitment to diversity, customer service and an unparalleled level of professionalism.

Over the last seven years, InfraStructures has become a leader in its field. First by becoming the only magazine covering all aspects of the industry published in French in Canada. Then by being the first to publish all its editorial content on the web, and also by being the only construction magazine, published in French, having a significant readership outside the Province of Quebec. ÉDITOR / PUBLISHER Jean-François Villard For many years, we have received requests for an English version of InfraStructures. Technical limitations, and the lack of advertising revenue have prevented us from publishing such a magazine in print. Now, with the ADVERTISING extent of the use of Internet by professionals, we feel that the time as come MONTRÉAL for a portable digital file (.pdf) version of InfraStructures in English. Jean-François Villard André Charlebois While the content of the English version differs slightly from the original, most of the important news will be published in English. In the near future, QUEBEC City more and more of the content of the original will be translated into English. Gilbert Marquis (418) 651-1176 With over 500 visitors per day on average, spending over 13 minutes per visit, the website of InfraStructures in one of the most important sites of this kind.

Future Directions in Calendering Research
Preferred citation: T.C. Browne and R. H. Crotogino. Future Directions in Calendering Research. In The science of papermaking, Trans. of the XIIth Fund. Res. Symp. Oxford, 2001, (C.F. Baker, ed.), pp 1001–1036, FRC, Manchester, 2018. DOI: 10.15376/frc.2001.2.1001. FUTURE DIRECTIONS IN CALENDERING RESEARCH T.C. Browne and R.H. Crotogino Paprican Pointe-Claire, QC, Canada ABSTRACT Calendering is the papermaker’s last chance to reduce thickness variations along the length and width of the finished sheet, and to improve the sheet smoothness. A smoother sheet results in improved print quality, while more uniform thickness profiles improve the winding process. The calendering operation thus improves the quality of the finished product. In recent years there has been an increase in the loads, speeds and temperatures at which soft-nip calenders, whether on or off line, can be operated without mechanical failure of the cover; the result has been an improvement in the surface and printing properties achievable with mechanical printing grades of paper, and an increase in the production rates which can be sustained. As a result, these calen- ders have slowly replaced traditional machine calenders in new and retrofit installations. The best available design and trouble-shooting tools for modern machine calenders are based on empirical models, whose coefficients have not been related to fundamental paper or fibre properties. New furnishes therefore require experimental deter- mination of these coefficients, and extrapolation to new calender- ing conditions involves some risk. As well, there are no published models, empirical or otherwise, for the design and trouble- shooting of soft-nip calenders, an unfortunate state of affairs given the increased number of installations of these machines. -

Corrugated Board Structure: a Review M.C
ISSN: 2395-3594 IJAET International Journal of Application of Engineering and Technology Vol-2 No.-3 Corrugated Board Structure: A Review M.C. Kaushal1, V.K.Sirohiya2 and R.K.Rathore3 1 2 Assistant Prof. Mechanical Engineering Department, Gwalior Institute of Information Technology,Gwalior, Assistant Prof. Mechanical Engineering 3 Departments, Gwalior Engineering College, Gwalior, M. Tech students Maharanapratap College of Technology, Gwalior, [email protected] [email protected] [email protected] ABSTRACT Corrugated board is widely used in the packing industry. The main advantages are lightness, recyclability and low cost. This makes the material the best choice to produce containers devoted to the shipping of goods. Furthermore examples of structure design based on corrugated boards can be found in different fields. Structural analysis of paperboard components is a crucial topic in the design of containers. It is required to investigate their strength properties because they have to protect the goods contained from lateral crushing and compression loads due to stacking. However in this paper complete and detailed information are presented. Keywords: - corrugated boards, recyclability, compression loads. Smaller flutes offer printability advantages as well as I.
