摘要
<p>The device comprises a bent edge bar (1), which has two opposite vertical starting edges (2) and two inner lying metal inserts, which are provided parallel to the starting edges. The friction forces are developed between metal inserts (3) and a base body (6). The bent edge bar is non-elastic after the bending process by the effect of the friction forces and the starting edges are dimensionally stable by the inelasticity.</p>
