Abstract

The unit includes a tensile strap (2) with a closed-contour frame (2.2) formed by two opposite segments (2.3). The tool (12) is located between them. Each segment has contact surfaces (2.1, 2.4), and the frame material is a reinforced composite. The contact surfaces correspond with surfaces (3.1) above or below the tool. Closure forces amounting in total to 1 MN can be applied to the component and contact surfaces. Resultant forces are parallel and lie in a plane dividing the strap centrally in the axial direction.
