ABSTRACT:
The driver (12) comprises a carrier (14) for attachment to a conveyor, for example an endless chain. A pusher (16) made of hard-wearing material is attached to the carrier (14) in such a way that when the support moves forwards the pusher engages a rear edge of a sheet (10) to be fed. The pusher (16) is supported through at least one elastic spacer (18) on the carrier (14), in a rearwardly resilient manner. In a preferred embodiment of the driver (12), the pusher (16) comprises a flexible metal sleeve (30) which near each of its two ends rests, by way of a respective spacer (18) in the form of an electrically insulating washer, on a shaft (20) attached to the carrier (16). This makes high rates of acceleration possible when feeding thin metal sheets on a can welding machine, without the sheets being damaged by the driver (12).
