For welding a longitudinal seam of cladding tubes of cables, wherein the cladding tubes consist of a metal strip bent into a tube (5), an apparatus (1) is provided, comprising two welding devices (2, 3) each with two welding heads (10, 11). While the longitudinal seam is being welded, the welding guns of the welding heads (10, 11) are made to track along the welding location with the aid of optical devices (15) that are designed in the manner of a Scheimpflug camera and capture the position of the welding location (join) between the longitudinal edges of the metal strip bent into the tube (5). A further laser device 20 captures the vertical position of the tube (5), and so the welding head (10, 11) can in each case be kept at the correct distance from the tube (5) and made to track correspondingly. The use of two welding devices (2, 3) makes it possible when performing maintenance work or exchanging the welding electrodes of the welding heads (10, 11) of one welding device (2 or 3) to use the other welding device (3 or 2) respectively, and so continuous working is possible.
A device for moving plate-shaped objects from a removal point, in which the objects are oriented substantially perpendicularly, to a delivery point, in which the objects are oriented substantially horizontally, includes a removal gripper moveable to and fro between the removal and the delivery points by a drive and which is rotated during the movement. The removal gripper is arranged on a lever so as to rotate with respect to the lever, which is pivoted to and fro by a drive. The removal gripper is connected to a shaft mounted rotatably in the lever and on which a wheel is fastened. An elongate, flexible element is placed over the wheel and fixed immovably in the direction of the longitudinal extension thereof. During pivoting of the lever, the wheel rolls on the elongate element. The movement of the gripper is thus superimposed with a rotational movement of the removal gripper.

In order to test battery plate packs (12, 13), the battery plate packs are transported between conveyor belts (5, 6) while compressed to a specified thickness, and the force required for the compression is detected by measuring cells (14) while the battery plate packs are being transported, which measuring cells are associated with a pressing plate (11) associated with one of the conveyor belts (5). If the force deviates from a specified value, the battery plate pack is evaluated as faulty and is ejected.
