SOFT AND RESILIENT FORMED FILM
摘要:
A dried soft and resilient formed film (46) is made by extruding a polymer (12) from a die (10) onto a rotating screen (14) supported by a block (24). A vacuum created at a vacuum block (16) by suctioning air at one or both ends of a vacuum tube (18) forms a microapertured film. A water stream (22) from a water jet nozzle (20) impinges on the film to form microprotuberances on the film. Water is removed from the film and collected in a drip pan (32) with a removal roller (30) and by blowing air through a tube (28) and exiting at a blower block (26). The soft and resilient film (42) is removed from the screen (14) by a roller (40) and dried in a drying apparatus (44).
