The conveyor apparatus is connecting a cutter, by means of which sheet metal blanks are produced in adjacent rows, to the magazine of a can welding apparatus which produces from the sheet metal blanks can bodies. A row of adjacently arranged depositing receptacles for receipt of at least one sheet metal blank each is located along the cutter on a frame. Two conveyor chains having dogs move along the depositing receptacles of which each presents a bottom surface which rises in the direction of transport such that the dogs push the sheet metal blanks from one to the next depositing receptacle and accordingly collect the sheet metal blanks out of all depositing receptacles such to form a pile at the end. Such pile is taken over at the end of the path of transport of the conveyer chains by a further conveyer means in form of elastically supported pawls. These pawls push the pile on a slanted rising slideway in a timed fashion by a certain span of the path of transport and are moved oscillatingly and are pressed under the pile during their reverse movement. By means of the pawls the staple is moved into a turn-over apparatus which includes two disk wheels which move rotatingly in slots in the slideway after a respective pile of sheet metal blanks has been pushed into radially extending slots in the two disk wheels. After a rotation of 180.degree. each pile has been turned over and is transported on the adjoining slideway by further pawls, of which a plurality is provided along the slideway, into the magazine. The turn-over apparatus is only facultatively present for the case that printed sheet metal blanks must be turned over.

Conveyor apparatus for the transport of sheet metal blanks

In order to produce can bodies having a noncircular cross-section, preferably a rectangular cross-section with rounded corners, flat planar blanks are initially deformed in a deforming station by a plurality of similar bending tools, each for producing one respective bend, whereby a respective different bend is made at the same time at the various blanks of the stepwise timed advancing blanks. The bending tool includes a shaping member held stationary at the inside and having a curved outer surface end, furthermore, a roller supported in a supporting body and which is subjected to the action of a spring pressing against the supporting body in order to bend the blank located between the shaping member and pressing roller upwardly during movement by a lifting rod pivotably mounted at the supporting body. This proceeds simultaneously in all bending tools provided for one respective bend by a movable part of the deforming apparatus operating as a press. The blank is moved stepwise from one to the next bending station, such that after a plurality of operating steps a can body having a rectangular cross-section and rounded corners is formed of which the free edges are interconnected in a next following welding station by electrical resistance welding.

Method and apparatus for producing can bodies of a non-circular

A welder for welding side seams of tubular bodies. The welder has a body feed in the form of a single conveyor which serves to receive bodies at regular intervals from a rounded unseamed tubular body supply and to move the bodies into a welding head nip with the bodies being initially widely spaced and then the gap between a body in the welding head and a trailing body being rapidly reduced so that the leading edge of a following body enters into the nip at the same moment as the trailing edge of a leading body begins to depart from the nip, with the adjacent edges of adjacent bodies being in substantially touching but positively spaced relation.
