MANUFACTURE OF POLYOLEFIN RESIN CROSSLINKING FOAMED BODY AND ITS MANUFACTURING DEVICE

摘要

PURPOSE:To provide a process and manufacturing device for manufacturing a polyolefin resin crosslinking foamed body, flat and without crease by stretching a foamed sheet foamed in a foaming oven outside in the width direction. CONSTITUTION:In the process of manufacturing a crosslinking foamed body in which a foamed polyolefin resin composition sheet is crosslinked and then heat foamed, a foamed sheet 6 is stretched outside in the width direction by passing the foamed sheet 6 over a foamed sheet width stretching device consisting of two rolls 7 and 7' disposed in the chevron shape in the neighborhood of the foaming terminal. The foamed sheet width stretching device consisting of rolls 7 and 7' is disposed adjacent to a foaming over 9.
