Abstract: A cable saw for cutting a workpiece includes a circulating saw cable, a guide device, and a cable storage device and cable tensioning device. The saw cable is driven by a drive and includes a sawing section. The guide device is arranged to move the sawing section along a cutting direction for cutting engagement with the workpiece. The guide device is arranged to allow several movement directions including the cutting direction and at least one lengthening or shortening of the sawing section. The cable storage device and cable tensioning device is arranged for storing, releasing and/or tensioning the saw cable when changing a position and/or length of the sawing section. The guide device includes a lever gear with a pivot lever rotatably hinged to a base holder. The lever gear is arranged to convert a rotational movement of the pivot lever into a movement of deflection rollers—which form the sawing section therebetween—to lengthen and/or shorten the sawing section.

Abstract: A device for controlling and positioning a carriage in a tool machine, in particular the feed carriage on a gear hobbing machine. The device utilizes cams oriented one after the other and which operate a plurality of switches to control the advance of the carriage. The end position of the carriage which is controlled by a control switch is determined by two cam carriages. The first cam carriage is positionable with a rough or coarse adjustment relative to the machine frame and the second cam carriage is finely adjustable relative to the first cam carriage. The cam carriages carry the aforementioned cams to effect a control of the movement of the feed carriage path adjacent the workpiece.
