ABSTRACT:
A tube bending apparatus has a bed, a reciprocal feed carriage, power means to reciprocate the carriage, a first guide means at one end of the bed to receive the outer end of a first tube to be bent, mounted on said bed. Said apparatus includes a heating element on said bed outwardly of said first guide means adapted to surround the tube. The carriage is adapted to operatively engage the inner end of the tube for moving it outwardly of the bed. A bending arm at one end is pivotally mounted adjacent said one end of said bed and has gripping elements thereon to operably engage the outer end of the tube. The present improvement comprises a second guide means at the other end of said bed adapted to alternately receive the outer end of a second tube. A second heating element is mounted on said bed outwardly of said second guide means. A second bending arm at one end is pivotally mounted adjacent the other end of said bed and includes gripping elements to operatively engage the outer end of a second tube insertable upon said bed after initial bending of said first tube. The carriage on movement in the opposite direction operatively engages the inner end of the second tube alternately projecting it outwardly of the bed.
