ABSTRACT:
A folding machine has a pair of longitudinally extending folding members which in a rest position shown in chain dotted outline have horizontal co-planar upper surfaces. A holding tool 41 holds a workpiece 42 on the folding members. To produce a fold or bend, the folding members are swung upwardly and outwardly about a common axis to form the workpiece around the holding tool. The adjacent edges of the folding members have interengaging projections and recesses so that the folding members overlap each other in the rest position.
