May 25, 2005 · In operation, film is drawn over a forming shoulder and the good design of the surfaces of the shoulder is vital to the successful operation. This paper reviews underlying geometrical definition for the shoulder, corresponding to a filling tube with circular cross-section.
Forming shoulder design with 60 degree back angle. A parameterised model based on the mathematics of differential geometry has been developed. The shoulder is part of a family of surfaces called ruled surfaces. A successful shoulder should guide the material from the flat to the tube shape without stretching, tearing or wrinkling the material.
