Abstract (en)
An automatic machine for bending and/or calendering spacer profiles (1) intended to form spacer frames (4, 4', 4") for an insulating glazing unit (5) composed of: a carriage or a belt feeder (300) for the synchronous movement of the spacer profile (1) upstream of a bending head (400); a bending head (400) composed of a matrix that consists of jaws (401a, 401p) that are adjustable as a function of the width of the spacer profile (1) and of a punch (402) that can be moved toward the inside curve of the profile; a bending lever (403) directly downstream of the punch (402) that is provided with a synchronous rotary motion (co); the coordinated operation of all these mechanisms actuating the bending and/or calendering according to the background art, downstream of the bending head (400) there being a mechanism (100) that mates with the initial portion (2) of the spacer frame (3, 3', 3"), supporting it and guiding it during all the operating steps of bending and/or calendering along a path that is synchronous with the geometric position described by the initial portion (2) of the spacer frame during the forming of the spacer frame (3, 3', 3") performed by the feeder (300) and by the bending head (400).
