Abstract (en)
The present invention relates to an automatic bending unit (1) for bending end portions of metal wire elements (F) of an electro-welded mesh (R) lying on a work surface (P), comprising a counteracting member (20) comprising a counteracting surface (22) adapted to lock a wire element (F) and define the bend starting point, bending means (30) comprising at least one bending head (31A, 32A) arranged and configured to bend said wire element (F) around said counteracting surface (22), and abutment means (40).The counteracting member (20) and said bending means (30) are adapted to be moved in a coordinated manner between a non-operative position, wherein said counteracting surface (22) and said bending head (31A, 32A) are arranged in a first side with respect to said work surface (P) and do not interfere with the extension of said wire element (F), and an operative position, wherein said counteract surface (22) and said bending head (31A, 32A) are arranged in a second side with respect to said work surface (P) and interfere with the extension of said wire element (F) to obtain its bending with a plastic deformation. In particular, said abutment means (40) are also movable with respect to the said work surface (P) between a non-operative position and an operative position independently with respect to the said counteracting member (20) and said bending means (30). The present invention also relates to a process for the automatic bending of metal wire elements (F) of electro-welded meshes (R).
