Abstract: A sheet feed apparatus for an imaging device. The apparatus includes a drive roller, plurality of sheets of photosensitive material, a photographically inert liner having upper and lower surfaces and a container for storing the sheets of photosensitive material. Proper feeding of the sheets of material and a stable location of the liner are ensured by appropriate coefficients of friction between the respective components. The top surface (19b) of the liner (19) to the bottom surface (18B) of the sheets (18) has a first coefficient of friction and the bottom of one sheet (18) to the top of another sheet (18) has a second coefficient of friction, the second coefficient friction being less than the first coefficient of friction, whereby multiple feeds of the sheets are reduced.

Abstract: A composite elastic material is provided having improved hysteresis comprising a layer of an elastic material bonded to a layer of nonelastic material at least one side. The elastic material layer is made from a blend of a narrow polydispersity number polymer and a conventional elastomer, and the blend is essentially free of low molecular weight polyethylene processing aids. The composite elastic material laminate should have a hysteresis at least 15 percent better than a similar laminate made without the narrow polydispersity number elastomer but with the processing aid.

Abstract: Transversely stretchable elastic laminated fabric with cloth-like facings was made by a two-step process. In the first step an inelastic laminate was made by continuously extruding an elastomer sheet between two plies of a fibrous sheet and joining the plies by applying pressure on them between a closed gap niproll assembly. Two longitudinal slits were made into the laminate. Then the rolls of inelastic laminate so made were taken to an oven and the laminate was unwound and pulled through the oven at an elevated temperature, while tension on the web was increased until the slits necked. The necked laminate was wound up on a takeup roll. When samples were unwound, surprisingly they did not grow in width, and they showed good CD-elasticity (elongation and springback). Breathability of the laminate was superior to the laminate formed using an open niproll assembly gap.

Abstract: A container and liner combination includes an interlock feature. Multiple sheets of photosensitive material are placed on the liner. The container has a base in which the liner is positioned. The base has a interlock feature and the liner has a mating interlock feature. The interlock feature prevents movement of the liner in the feed direction as well as in a direction opposite the feed direction.
