Abstract

In a process and an apparatus for detaching a lining of thin composite material from a central region, the detachment operation is effected in a continuous procedure with the composite material in the form of an endless web. The composite material passes as a treatment region successively through an initial dissolution region and a deactivation region, in each of which inter alia moisture is fed to the composite material. The residence times in those regions are controllable independently of each other and at least at the end of those regions a respective operation for the preliminary removal of moisture from the composite material is effected. After the last region the composite material is subjected to a drying operation and the lining is detached from the central material by their being moved away from each other.
