Abstract: On a machine for welding together the longitudinal edges (12, 14) of rounded sheet-metal container body blanks there are disposed a plurality of rings (24) of rollers round a common longitudinal axis (22), one behind the other in the direction of passage through (A) of the blanks (10). At least some (28) of the rollers (26, 28) of the rings (24) of rollers are each mounted on a roller carrier (40) which is adjustable in the direction away from the longitudinal axis (22) against resilient resistance. The roller carriers (40) are guided in a manner which enables the associated rollers (28) to execute yielding movements at an angle of distinctly less than 90.degree. to the direction of passage through (A) of the blanks (10). For this purpose, the roller carriers (40) are each pivotable about a transverse pin (42) which is disposed at least substantially parallel to the associated roller spindle (38), upstream of this with respect to the direction of passage through (A) of the blanks (10). This guiding of the roller carriers (40) makes an important contribution to avoiding damage to the leading edges (16) of the blanks (10) and to reducing the noise occurring when these leading edges (16) impinge on the rollers (28).

Abstract: In conventional methods for welding can bodies along their longitudinal seams, high frequency substantially rectangular a.c. currents are used for the welding current to avoid the problem of arcing found in d.c. welders. However, the high frequency a.c. current causes an undesirable degree of heating which produces eddy currents and necessitates cooling equipment. To overcome this problem, a method of producing can bodies welded along their longitudinal seam is provided in which the length of a half wave of the substantially rectangular welding current is matched in length and concurrent with the amount of time required for a can body to pass between the welding electrodes.

Abstract: An apparatus for positioning and guiding the opposed edges of sheet metal so that the edges thereof are progressively moved into substantially intimate relationship with one another so that such edges may be subsequently welded to form a seam. The apparatus includes three replaceable guide elements that cooperatively form opposed and relatively converging guide channels which progressively direct the sheet metal edges into intimate relationship and maintain such relationship as the sheet metal is introduced into a seam welding station.

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.

Abstract: A pair of catches (74) is mounted on a sliding carriage (20) which is movable forwards and back along a guide (18) between a rear and a front dead centre (C,F), the catches being pivotable backwards and forwards between a working position and a position of rest. In order to move the sliding carriage (20) along the guide (18), a crank drive is provided. This has a crank (30), which can be driven in rotation, and a connecting rod (40), which is connected by a crank pivot joint (36) to the crank (30) and by a connecting-rod pivot point (42) to the sliding carriage (20). A control mechanism allows the catches (74) to assume their working position near the rear dead centre (C) of the sliding carriage (20) for its forward movement and to assume their position of rest near the front dead centre (F) of the sliding carriage (20) for its backward movement. The control mechanism comprises a bistable spring arrangement (44,50) which is disposed between the connecting rod (40) and the catches (74) and assumes each of two stable end positions once during each complete revolution of the crank (30).

Abstract: The apparatus described is so constructed that narrow can bodies having an internal diameter of 52 mm for example can be produced from rounded blanks by welding the edges of the blanks. The supply of welding current to the electrode roller is effected through copper caps, a clamping member, contact members disposed at each side thereof, contact jaws silver contact segments and peripheral surfaces of wide hubs which are provided on the electrode roller. The contact jaws engage the hubs of the electrode roller at both sides of the roller from above and below, as a result of which there is a large area for the transmission of current and a low specific contact pressure. The hub surfaces, which form the actual contact surfaces of the electrode roller, are continuously lubricated through felt lubricating segments. The contact pressure of the contact jaws can be adjusted in a simple manner by means of a screw. The whole apparatus and particularly the electrode roller are extensively cooled internally by a special cooling device.
