Abstract (en)
A method and apparatus for shredding or fibrillating sheet material, such as plastics film. The sheet material is drawn past a series of inter digitating fibrillating members and spacers which rotate. Each spacer (1) is generally elongate and has a concave arcuate portion (3) extending rearwardly from its acute angled leading end (2). The apparatus includes means for reducing the tension of the fibrillating members and/or spacers, once fibrillation has commenced to prevent clogging or jamming caused by the sheet material getting between a spacer and fibrillating member. <IMAGE>
