Abstract (en)

[origin: EP1393831A2] The bending support (14) pivots under its own power round the swivel axis (18) of the bending jaw (12) or axis parallel to this and both parts (14a) of the support are excentric to the axis (18) to make up peripheral sections addressed respectively to the inside (22) of the hollow profile bar (20) when the support pivots. In this position the sector lies spaced from the plane (17) in which support (16) and jaw (12) lie flush with the first support sector (26a). The bending support (14) can pivot along with the jaw (12) round axis (18). Support (14), or support part (14a), are at the tip of backholder (13) which faces the jaw (12) and is in turn applied to the inner wall (23) of the hollow profile bar (20). The backholder (13) comes in wedge shape so the tip faces the bending support (14).
