Abstract: A press pad is provided for use in a laminate press. The pad includes a woven fabric of heat resistant strands wherein at least either the warp or the weft has a core made up of a plurality of strands within a sheath of an elastomeric material, and the other is made up of metal strands. Within the scale of the press pad, the strands making up the core lie substantially parallel to one another and to the longitudinal axis of the core. In use, therefore, when pressurized in the laminate press, the core structure collapses as the strands making up the core move relative to one another and the core tends to flatten out. This increases the springiness and compensation ability of the press pad without any loss of heat transfer ability.

Abstract: The present invention provides a body-adhesive tape having adhesive properties preventing the tape from peeling off due to sweat when it is applied in an overlapped manner, and which also has good moisture permeability. In the body-adhesive tape, a base cloth is formed from a stretchable warp thread and a standard weft thread. On one side of the base cloth a plurality of pressure-sensitive adhesive layers are formed separated by appropriate gaps. The pressure-sensitive adhesive layers are formed so that they meander left and right along the length of the tape. At the gaps, the base cloth is exposed so there is permeability. Since the gap meanders, it is longer than the tape, and thus there is more exposure of the weave and more permeability. The pressure-sensitive adhesive layers meander so that the tape can be attached anywhere on the body and can respond to tension due to body movement from any direction.

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.
