Abstract
The invention concerns itself with an apparatus and method for producing plastic slivers from plastic infeed stock. The splinters produced are especially suitable for use in plastic or cellulosic/plastic composites. The invention will readily accommodate a broad range of types and forms of plastic infeed stock, including waste plastic, whether or not it has been cleaned and sorted into homogeneous feed streams. The method cuts plastic into slivers by firmly holding the plastic infeed stock and slowly feeding it against rotating cutter heads. The feed mechanism automatically adjusts to varying amounts of feed stock. The slivers need no further processing before they can be used in composites.
