<p>A folding machine has a pair of longitudinally extending forming 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 forming members. To produce a fold or bend, the forming members are swung upwardly and outwardly about a common axis to form the workpiece around the holding tool. The adjacent edges of the forming members have interengaging projections and recesses so that the forming members overlap each other in the rest position.</p> |
