ABSTRACT:
A tube bending apparatus made up of a drive motor, bend head and saw together with associated clamping units are mounted on a common work surface, the apparatus being programmed to form rectangular window frames by coordinating the speed of advancement, distance of travel between bends as well as the sequence of bending and cutting with operator input data relating to quantity and frame dimension. The machine can be operated either in a manual or automatic mode, and in the automatic mode is operable at different selected speeds, according to the length of sides of the frame, with a reduced speed interval at the end of each period of advancement preliminary to braking and clamping of the workpiece to perform either a bending or cutting operation.
