Abstract
A conveying apparatus feeds can body blanks to a welding unit with the longitudinal edges of the can body blanks even, without being offset in the longitudinal direction. The apparatus includes a centrally disposed revolving device (5; 5'; 5') which serves as a transport unit for the can body blanks (1). Rockers (18) are connected by means of swivel axes (5b) to serve as pusher dogs. Each rocker (18) has two feed pins (18c, 18d) at its front end facing the direction of transport. In the pushing position, the feed pins simultaneously contact the rear edge of a can body blank (1) on either side of the longitudinal edges. Each of the rocker arms is provided with a control arm which extends past the swiveling axis and which has a control surface.
