<p>A band saw strip manipulator (10) is arranged to receive a toothed metal strip (12) for welding from a cut to length machine (13). The strip (12) is moved into the band saw strip manipulator (10) by powered rollers. The strip (12) extends between a first edge detector (14) at one side of the manipulator (10) and a second edge detector (16) at the opposite side of the manipulator (10). First and second end clamps (18 and 20) are located to either side of a carriage (22) mounted for vertical movement. When the strip (12) has been approximately centrally located in the manipulator (10) the carriage (22) moves upwardly from the position shown in figure 1 thereby pulling the strip upwardly until the edge detectors (14 and 16) detect the ends of the strip (12). The first and second end clamps (18 and 20) are then closed and pivoted about first and second guide rollers (24 and 26) so that the two ends of the strip (12) are located in close proximity for welding together.</p> |
