Abstract
An inflatable backup pad adapted to be mounted upon the ironer rolls of an industrial type ironer and having opposite ends detachably connectable, in combination with a roll cover adapted to surround the exterior surface of said pad and the ends of said cover also being detachably connected to define the outer operative surface of the ironer roll, said cover being distended to its full circumference when said pad is inflated and thereby cause said pad to frictionally engage both the ironer roll and said cover to prevent appreciable relative movement therebetween.
Claims9
A pneumatic pad and roll cover assembly for use upon rotatable ironing cylinder members of an industrial ironing machine comprised of an initially substantially flat flexible pneumatic member having a pair of similar impermeable elastic walls and said pneumatic member also having opposite ends and a length and width adequate to substantially circumferentially and longitudinally envelope said ironing cylinder members, means to secure said opposite ends of said pneumatic member together when extended around said cylinder, a flexible substantially inelastic cover member having opposite ends and substantially circumferentially and longitudinally enveloping said pneumatic member when extended about an ironing cylinder, and means to connect the opposite ends of said cover member in circumferential and longitudinal cylindrical envelopment about said pneumatic member when mounted upon said ironing cylinder to restrict the expansion of said pneumatic member to a pre-determined circumferential dimension, whereby when said pneumatic member is inflated with gas under a limited pressure said pneumatic member is elastically distended radially inward to compressively and frictionally engage the longitudinal outer circumference of said ironing cylinder member with one wall of said pneumatic member and said pneumatic member also is distended radially outward to frictionally engage the longitudinal circumferential cover member with the opposite wall of said pneumatic member, thereby being adapted to provide an ironing cylinder having a compressible and yieldable pressure surface throughout the entire circumference of said cylinder.
