Abstract
The present invention relates to apparatus for fibrillating ribbons or foils, wherein two or more strips each having a plurality of projecting fibrillating elements are disposed on the circumference of a fibrillating roll in a uniform distribution. To ensure gentle guidance of the ribbons and foils during fibrillation, the regions on the fibrillating roll between the circumferential strips each exhibit a friction-reducing surface contact.
