Abstract

See full text

A system for automatically forming sheet metal tubes from blanks cut to size. The system having a mechanism for positioning a blank for processing. A lifting arrangement having a wrap strap and pressure pad to raise the blank to a forming station having a mandrel is positioned so that the wrap strap extends on either side of said mandrel and underneath the blank before a side wiper on each side of said mandrel forces the overlap of opposite edges of the blank along a length of the mandrel. The mandrel includes a clinching die bar along its length. A sealing mechanism with a vertically movable row of clinching prongs is lowered to attach the overlapping edges of the blank by clinching at multiple positions to form a tube around the mandrel before being removed by a gag bar and a stripper plate.
