Abstract: A method and an apparatus for ensuring the dimensional accuracy of a frusto-pyramidal can body (10). During the production of the body (10) this is partially heated by means of inductors in the vicinity of its base face in the region of its broader side faces (10a,10b), before the step in which it is formed into the pyramidal frustum. In this manner, a uniform reduction in the thickness of the sheet metal is achieved in the region of the base face of the pyramidal frustum during the widening operation.

Abstract: An apparatus is described for positioning a can body in the form of a longitudinal seam welded cylinder which is provided with a tongue or the like projection at a predetermined point of its outer circuference, and which is to be further processed, for example shaped. The can body is received in a device in a spatially fixed manner and is rotated about its longitudinal axis. The rotational movement is stopped by a stop (48) or like sensor or obstacle in the path of the tongue, the position of the stop being so selected that the longitudinal seam of the body is then in a precisely defined position. The seam is thus detected in a simple manner by means of a tongue. It is thereby possible to ensure that when a circular cylindrical can body is, for example, further shaped into a parallelepiped body, the longitudinal seam is precisely in the middle of a narrow side of the parallelepiped body.

Abstract: During the rounding of sheet-metal blanks, problems have hitherto arisen in the rounding apparatus (2) because the leading edge of the rounded sheet-metal blanks struck against a stationary stop at the end (48) of a slit (24) between an inner shell (20) and an outer shell (22), so that the sheet-metal blank rebounded and did not have a defined starting position for further conveying. In order to overcome this problem, the stop is constructed in the form of a pivotally movable damping flap (50) on which there is formed a catch hook (54) which closes the slit (24) at its end (48). Compression springs (70) are disposed between the damping flap (50) and the inner shell (20). Under the impact of the sheet-metal blank, the catch hook (54) yields and urges the damping flat (50) about the pivot axis (52) pressing its front portion (50') into the slit (24) as a result of which the sheet-metal blank is temporarily clamped against the outer shell (22). Subsequently, the damping flap (50) is restored via the compression springs (70) and the rounded sheet-metal blanks can thus be taken over by the dogs (42,44) of the conveyor chains from a defined position and be conveyed further.
