ABSTRACT:
The present invention provides an apparatus to strip material from material cores. The apparatus of the invention comprises a frame; a belt attached to the frame; means for rotationally driving the belt; and means for biasing material to be stripped against the belt. According to the invention, the belt is an endless conveying belt, driven by a motor, gear box controlled with an A/C variable frequency drive. The material being stripped is biased against the belt by a plurality of positioning members rotatably attached to the frame. The positioning members are spaced at intervals along the length of the conveying belt such that the distance between ecah positioning member is greater than the diameter of the expiring material core being stripped. Each positioning member and the rotating belt meet to create a nip. An expiring core is placed on the rotating conveying belt and the leasing edge of the material is self-threaded into the nip. The material is then continuously drawn into and through the nip, unwinding the material core. The nip pulls the material from the expiring material core. The apparatus can be constructed to provide several nips along its length, each nip pulling the remaining material from an expiring material core. The stripped core can be removed and another unstripped core placed on the rotating belt. This eliminates the need to interrupt the run mode. The material, once stripped from the core, proceeds along the conveying belt and can be gathered manually or is preferably conveyed directly into a shredding and baling device.
