Abstract
Shears unit positioned immediately upstream of a bending assembly (13) comprising a bending disk (19) and support means (15) to change the reciprocal positions of a contrast roll (20) and a section or sections (11) in a bending-shaping machine, the shears unit including a stationary blade support (33) positioned astride and above a part of the bending disk (19), the blade support (33) bearing and positioning a laterally shearing stationary blade (34), which cooperates with a laterally displaceable blade holder (30).
Claims8
A shears-bending assembly comprising:
- a bending assembly comprising a rotatable bending disk having a contrast roll and a bending pin provided in an upper surface thereof, said bending disk being supported on support means for changing the reciprocal positions of said contrast roll and a section or sections to be bent;
- and
- a shears unit provided upstream of said contrast roll with respect to a direction of feed of said section or sections to be bent, said shears unit comprising a stationary blade support bearing and positioning a laterally shearing stationary blade and being positioned astride and above a part of said bending disk, a laterally displaceable blade holder, and means for laterally displacing said laterally displaceable blade holder toward said laterally shearing stationary blade for shearing said section or sections.
