    摘要: 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.

    摘要: This invention relates to gang saws and other cutting apparatus having oscillating cutters for cutting workpieces into slices. The invention provides apparatus, having two elongate spaced apart cutter supports which are driven to oscillate 180.degree. out of phase with each other. Two sets of cutters are connected to the supports. For a suitable workpiece the cutters may be of a hot wire type. Each cutter of one set is connected to the first support by a resiliently extensible connector such as a spring and to the second support by a non-extensible connection. Each cutter of the other set is connected to the second support by a resiliently extensible connector and to the first support by a non extensible connection. Desirably the cutters of one set alternate with cutters of the other and all cutters are coplanar. Movement of cutters of each set in opposite directions tends to cancel the local influence of cutters on the workpiece. Moreover whole frames of cutters may be removed and replaced, facilitating reprogramming of the apparatus in terms of spacings between cutters.
