ABSTRACT:
The removal of so-called zip-tape from reclaim tobacco is achieved by use of an elongate vibratory conveyor having grooves extending longitudinally therewith and of longitudinal depth profile preselected from groove-containment of the reclaim tobacco, except for the zip-tape content thereof. Rollers having surface affinity for the zip-tape are arranged in overlying relation to the conveyor surface and groove rises, and are disposed in acute angle relation with the conveyor feed direction. The rollers are supported for joint movement with the conveyor so as to be maintained in fixed relation to the conveyor surface during vibration. Zip-tape encountered by the surfaces of the rollers is withdrawn from the conveyor grooves and is displaced successively transversely of the conveyor for collection aside the conveyor.
