a movable front position b fixed rear position 8 the bottom heating system in the cooling step 5 cooled air is blown on the bending point thereby making again rigid the just bent material the blowing is performed through the cooling nozzle 5 the top punch 3 comprises therein an air distributing or delivering circuit not shown thereby holding the profile 2 locked also in the cooling step and preventing said profile from being deformed fig8 shows an operating step in which the bending paddle returns to its rest position in fig8 the reference numbers show 2 the profile being machined 3 the self adjusting top forming assembly with the built in top cooling system 5 the bottom cooling system 6 the profile raising bending system the profile raising paddle 7 the profile gripper at a bending position a movable front position b fixed rear position 8 the bottom heating system in this operating step it is possible to see the return of the bending paddle 6 to its rest or standby position whereas the cooling process is continued through the bottom cooling system 5 u2033 in other words after a suitable cooling period of time sufficient to stabilize the profile the bending paddle 6 which has previously bent the profile 2 is sent back to a standby or rest position whereas the cooled air feeding is continued finally with reference to fig9 and fig9 a to 9 d are herein shown the profile disengaging operations or movements in said fig9 and 9 a to 9 d the reference numbers show again 2 the profile being machined 3 the self adjusting top forming assembly with the built in top cooling system.
