Duct forming machine strip material alignment compensating system

摘要

This invention relates to a duct forming machine strip material feeder alignment compensating system which permits the adjustment of strip material being fed to a mandrel for forming duct. The strip feeder material is fed from a reel mounted on an adjustable platform. The platform is supported by the machine frame for vertical adjustment by a crank operated lead screw. Horizontal and vertical angular compensating adjustments of the strip material feed system are provided by adjustments of a spool axle mounting plate. The axle mounting plate is horizontally and angularly adjustable to keep strip material being fed from a spool to the mandrel of the duct forming machine in proper alignment.
