Abstract

In order to obtain better noise protection, longer service life of machine and tools, and to increase the productivity of wire shaping apparatuses, in particular, a universal spring winding machine with a cutting device (16) consisting essentially of a movable cutting tool (38) with drive (80) and a stationary cutting tool (150) at which the endless intaken wire is cut, this invention suggests: PA1 to conceive the drive of the cutting tool (38) in the form of a fluid operated cylinder piston aggregate cutting cylinder (80) with program-controllable NC valve (78); PA1 to fix the movable cutting tool (38) by means of an adapter (158) to the movable part of the aggregate (piston rod 154); PA1 to bring the moving direction of the latter (154) into accordance with the shearing direction of the movable cutting tool (38).
