ABSTRACT:
An apparatus for producing permanently set crumple pleat crease patterns in fabric webs, having a heatable crumple tube with an oscillatingly driveable stuffing element with which a fabric web in rope form is batchwise successively inserted into the crumple tube, compressed and finally forced out. Upstream of the entry end of the crumple tube there is a rope feed tube of smaller diameter than the crumple tube. The rope feed tube has a through-hole connected on the outside to a vacuum source, while part of the crumple tube is concentrically surrounded by a jacket tube. Annular gaps between the crumple and jacket tubes are tightly sealed by annular walls, thereby forming a heating chamber with an inlet and an outlet for a fluid heating medium. In the heating chamber there are an electric resistance heating element, a temperature sensor and a pressure sensor for determining the temperature and pressure respectively of the fluid fed into the heating chamber, and a control circuit for continuously processing temperature and pressure proportional signals developed by the sensors to control connection and interruption between an electric power supply and the resistance heating element.
