Abstract
A machine for assembling awning slats having a front longitudinal side edge portion curled downwardly and rearwardly along the length of the slat, and having a rear longitudinal side edge portion curled upwardly and forwardly along the length of the slat in the complementing configuration, has a pair of aligned anvils for receiving two side-by-side slats which are interfitted by their front and rear curled side edge portions. Punching units form locking tabs and registering cutouts in the interfitting side edge portions of the slats on the anvils and then the slats are advanced laterally a slat width by slat shifting units to receive another interfitting slat fed longitudinally onto the anvils. Slat hold-down units cooperate with the anvils during the slat punching and feeding operations.
