Abstract

Machine to draw bars, which comprises a die-holder drawplate assembly and a drawing assembly (11) of the type disclosed in EP-A-548723 and also comprises an assembly for the reciprocal adjustment of chain assemblies (13-113), an assembly of links and an assembly for backward drawing, in which the drawplate (12) includes downstream momentarily actuated grippers (17) and is associated with a carriage (18) able to move along the drawing axis (15) upstream of the drawplate (12) by a length coordinated with the minimum length of clamping by the facing chains (13-113), the movable carriage (18) being associated with a first jack actuation means (22), the support (47) of the drawplate (12) cooperating during drawing with a toric load cell (33), the load cell (33) being associated with a unit (57) that governs means (32) that actuate angular displacement. <IMAGE>
