Abstract

The machine tool comprises a frame (1, 2, 3) with two fixing elements (22 and 39) for fastening a scroll saw blade. The fixing element (22) is driven by an electrical motor (5) in a vertical reciprocating movement. The two fixing elements (22 and 39) are linked to each other by a metallic ribbon (45) passing on pulleys (46 to 50). The position of the pulley (47) can be changed by means of a cam (53) acting on an arm (52) so as to stretch the ribbon (45) to the desired value.
