Abstract (en)
[origin: EP0344741A2] In an advancing device for feeding sheet metal (2) to at least one stationary stamping tool (11) with which blanks (10) are stamped out from the sheet metal (2), having an advancing beam (7, 8) mounted on one side and movable in the advancing direction on a conveying table (6), and having collet chucks (21) which grip the sheet metal (2) and can move laterally on the advancing beam (7, 8), transversely to the direction of advance, the stamping process can be carried out during transfer from one piece of sheet metal (2) to another without a return stroke when a second advancing beam (7, 8) is provided, when both advancing beams are mounted on one side in each case on a different longitudinal side of the advancing table (6), and when both advancing beams can each be pivoted up about a rotational joint (25) having its spindle pointing in the conveying direction. <IMAGE>
