ABSTRACT:
A folding machine has a pair of longitudinally extending forming members which in a rest position have horizontal co-planar upper surfaces 22 and 23. In use as a folding machine a holding tool (not shown) is supported on a holding bar 33 to hold a workpiece which is folded by swinging the forming members 15 and 16 upwardly and outwardly as shown. The folding machine is modified in accordance with the invention by the provision of a vertically guided horizontal platten 41 connected to the forming members by pivoted links 42 and 43 to enable the apparatus to operate a punch and die set 48. A fixed abutment 51 on the holding bar 33 operates the punch as the platten is raised.
