Abstract
A half-pulley matrix with a circumferential semicircular groove is secured by a wedge to the drive shaft of the motor and reduction gear. The tube is held between this groove and a matching groove in a linear tube fixture with fixed pivots at opposite ends. The similarly grooved counter matrix pulley is mounted on a vertical tubular axis on a baseplate which is pivoted on a projection from the casing. A pin slides out of this axis to engage in one of a number of holes corresp. to the dia. of tubing to be bent. The selected dia. is indicated by a pointer on a scale. The tube is bent by rotation of the matrix and frictional advance of the tube along the grooves.
