ABSTRACT:
An economical apparatus and method for reprocessing scrap film. The apparatus includes a film-air separation chamber for separating air from incoming strips of scrap film, a cutter for cutting the strips into fine pieces, and a storage tank or further reprocessing means to which the cut pieces of scrap film are conveyed. A air bypass line having a computer-controlled valve conveys air directly from the film-air separation chamber to the cutter outlet when the valve is in an open position, and causes all of the air to flow into the cutter inlet when the valve is in a closed position. The open or closed position of the air bypass valve depends upon the cutter motor power, which varies as the volume of scrap film in the cutter varies. Due to the inclusion of the accurately controlled air bypass valve, only a single fan is needed to convey the film into and out of both the film-air separation chamber and the cutter.
