Abstract: Ebene, rechteckige Bleche (10) werden zwischen einer angetriebenen Biegewalze (32) und mehreren Stützwalzen (34) hindurchbewegt und von diesen sowie mehreren hinter der Biegewalze (32) und Stützwalzen (34) angeordneten Andrückwalzen (52, 56) um die Biegewalze (32) herumgebogen. Das annähernd vollständig gerundete Blech (10) wird durch einen Ablenkkörper (62) elastisch von der Biegewalze (32) weggebogen, wodurch die Vorderkante (10a) des Blechs daran gehindert wird, erneut in den Spalt zwischen der Biegewalze (32) und den Stützwalzen (34) zu gelangen, ehe die Hinterkante (10b) des Blechs durch diesen Spalt hindurchgewandert ist. Anschliessend wird der Ablenkkörper (62) in seine Ruhestellung zurückbewegt, so dass der vordere Bereich des Blechs (10) in Richtung zur Biegewalze (32) zurückfedert und dadurch erneut von der Biegewalze (32) und den Stützwalzen (34) erfasst und zwischen ihnen hindurchbewegt wird. Wenn die Vorderkante (10a) des Blechs (10) in den Zwischenraum zwischen den beiden letzten Andrückwalzen (56) gelangt ist, werden sämtliche Andrückwalzen (52, 56) angehoben. Anschliessend wird das Blech (10) von einer Rundstation (31) zu einer Positionierstation (69) transportiert. Das Blech (10) wird von der Biegewalze (32) weitergedreht, bis seine Vorderkante (10a) von Fanghebeln (68) festgehalten wird. Das gerundete Blech (10) wird nun axial von der Biegewalze (32) abgestreift.

Abstract: On a machine for welding the longitudinal edges (12,14) of rounded body blanks (10), two groups of movable guide elements (36), which exert radial guiding forces on the blanks (10), are arranged lying opposite one another with respect to the blanks. The guide elements (36) of each of the two groups are secured to an endless chain (38). Each of these chains (38) has a chain strand extending in the direction of movement (axis A) of the blanks (10), which strand is supported by a rail (52) at both sides of a welding plane (B) containing the welding zone and normal to the direction of movement of the blanks (10). The guide elements (36) move through the welding plane (B) with the blanks (10). As a result, shock-like actions on the blanks (10) in the vicinity of the welding plane (B) are avoided; consequently, the longitudinal edges (12,14) can be welded together particularly evenly, particularly by means of a laser beam.

Abstract: Two endless flexible conveying strands (22, 24) run, parallel to one another, over a drive mechanism (26, 28), a guide mechanism (30, 32, 34) and a conveying track for the body blanks (10). The two conveying strands (22, 24) are displaceable in relation to one another to a limited extent in their longitudinal direction in operation. Pusher dogs (46, 48) are secured one behind the other to the conveying strands (22, 24) with equal spacing so that situated opposite each pusher dog (46) on one conveying strand (22) is a pusher dog (48) on the other conveying strand (24) so that these two associated pusher dogs together push a can body blank (10) over the conveying track to a welding apparatus (20). The pusher dogs (46, 48) each have a lateral projection (50, 52). Disposed on the conveying track, upstream of the welding apparatus (20), at a distance from this which coincides at least approximately to the length of the can body blanks (10), is a pair of adjusting templates (62, 64). The adjusting templates (62, 64) are rigidly connected to one another and can be brought into engagement with a pair of associated projections (50, 52) in order to bring these forcibly into alignment with one another in a direction transverse to the conveying track.

Abstract: Plane, rectangular sheets (10) are bent around a driven bending roll (32) by a number of back-up rolls (34) and pressure rolls (52, 56). The almost completely rounded sheet (10) is bent resiliently away from the bending roll (32) by a deflecting member (62) to prevent its front edge (10a) from re-entering between the bending and back-up rolls before its rear edge has travelled through between them. Then the deflecting member (62) is retracted and the front region (10a) of the sheet (10) springs back towards the bending roll (32) to be gripped again by the rolls. When the front edge (10a) of the sheet (10) has reached the gap between the last two pressure rolls (56), all the pressure rolls are lifted. The sheet (10) is then conveyed axially from the rounding station (31) but continues to be rotated by the bending roll (32) until its front edge (10a) is arrested by catching levers. The rounded sheet (10) is now stripped axially off the bending roll (32).

Abstract: For the electric resistance seam welding of tin plate, welding machines with wire electrodes are used. If only one electrode wire, running over both electrode carrier rollers, is used, a hard wire is required to prevent loop formation in the wire winding between the electrode carrier rollers. Hitherto, this has been produced by rolling a soft round wire. However, this rolling process produces uneven hardness distribution over the cross-sectional area of the wire, with zones of high material work hardening and zones of low material work hardening, with the result that the average increase in the strength of the electrode wire in relation to the total cross-section of the wire is always below the increase in strength which could theoretically be achieved if it were not for the fact that part of the cross-section of the wire does not participate in the high material work hardening. A closer approximation to this theoretical increase in strength has been achieved by replacing the rolling process with cold deformation in several steps. In this process, the round wire is drawn to a smaller diameter in a first deformation stage and then subjected to cold deformation in a second deformation stage by rolling flat. In addition to advantages in terms of welding, this also results in significant savings of wire.
