ABSTRACT:
An improved transfer system is provided for guiding a thermoplastic injection runner from a conveyor into a collection hopper. A thermoplastic runner, which results from the injection molding of plastic parts, such as closures, is moved by a conveyor to a transfer drum which utilizes spikes to direct the runner into the hopper. The closures are separated from the runner as it moves along the conveyor and fall into a collection device at the end of the conveyor. A unique separation grid is positioned above the transfer drum and serves as a guide for the runner as it is directed by the spikes on the transfer drum from the conveyor into the hopper. The separation grid prevents the runner from becoming entangled with the drum or from dropping to the floor. The runner material collected in the hopper can be salvaged for recycling after it has been processed in a grinder.
