ABSTRACT:
The device comprises a flat block with a pair of rods carrying two respective teeth, reciprocated as one in the direction followed by cans conveyed from a forming station to the welding station by a pair of chain loops driven at constant operating speed; from a fully retracted position, in which the rods engage the rolled shell of the can essentially at standstill, or in any event at minimal velocity, the block accelerates to an intermediate position at which its velocity reaches a calculated maximum and is matched substantially to that of the chains, whereupon the can is taken up by the chains and the block decelerates in the same direction toward a fully extended position before reversing.
