ABSTRACT:
The present invention relates to a method and an apparatus for producing mat packets from panels of an adhesive material which adhesive material is covered with release layers. The panel of adhesive material is advanced sequentially through a feed device, a clamping device, a release layer removing device and a cutting device. The leading edge of the panel, with the release layers removed, extends freely beyond the clamping device toward the cutting device. The panel is advanced in increments corresponding to the length of the mat strip to be produced, and, when the panels are clamped by the clamping device, the panels with release layers removed are cut into mat strips, which are deposited on a transporting device in stacks of several on top of one another to form a mat packet. In order to improve the economy and operational reliability of the method and of the apparatus, a supporting element is moved underneath the freely extending end section of the panel to support the panel and move in synchronism with the advancing of the panel. When the advancing of the panel is stopped, the supporting element is removed from underneath the panel and the mat strip is cut from the panel such that each mat strip is deposited on the transporting device or stacked on any mat strips previously deposited on the transporting device.
