摘要:
The invention relates to a pair of grabs, in particular of a transversal transport device in multiple-die presses, comprising a grab (10) that receives the workpiece (14) to be pressed and a grab (20) that retains said workpiece. The invention aims to prevent the axis of symmetry (12) of the workpiece (14) held by the grabs from being shifted laterally during the axial displacement of said workpiece by the pair of grabs (10-20). To achieve this, the pair of grabs that can be positioned on a plane of movement which is cut perpendicularly by the axis of symmetry is configured in such a way that the receiving grab has two fingers (10.1 and 10.2), (spread by at least 60°), which together with the single finger (20.1) of the retaining grab, form an intermediate space for the workpiece in the shape of an isosceles triangle (3x60°). Said intermediate space can be modified into geometrically similar intermediate spaces by simultaneous, uniform, linear movements of the two grabs in mirror image to a plane of symmetry (15) which is perpendicular to the plane of movement and contains the axis of symmetry.
