1434430 Endless conveyers GD SpA 27 Dec 1973 [9 May 1973] 59812/73 Heading B8A Packets P on a conveyer 2 are engaged by rollers 15 which are rotatable clockwise only, and any tendency for the packets to rebound off a wall 12 facing the discharge end of the conveyer 2 is resisted. Each roller 15 is mounted on a pivoted arm 14 provided with a spring 16 to urge the roller downwardly; a screw 17 limits the downward movement. The packets are fed, via a conveyer 1, from a wrapping line and, after passing from conveyer 2 on to a pusher conveyer 7-10, move to a machine for overwrapping the packets.
