ABSTRACT:
The present invention relates to a method and an apparatus for producing mat strips from wide panels or sheets of an adhesive material covered with release layers by subdividing the panels of material in the longitudinal and transverse direcitons subsequent to removing the release layers.
In order to improve the economy and operational reliability of such methods and devices, the present invention includes gripping an end section of the sheet of material, from which the release layers have been removed, by means of gripping members and longitudinally subdividing the sheet during its movement in a first direction to form longitudinal strips, by actuating a longitudinal cutting member, and thereafter servering the longitudinal mat strips by actuation of a transverse cutting member.
