Abstract (en)
[origin: DE10004904C1] The drive for the cutter blade slide, to sever the pile yarns between two layers of woven pile carpet fabrics, has a reversible servo motor at the double-pile loom controlled by a preset program. The system also has a path meter, and a transmitter to register the actual path movement units, and at least one transmission to move the slide along a guide rail. An inelastic transmission with a positive fit is between the cutting blade slide (3) and the monitor system (411,412), as a toothed belt (42,45), a spindle and nut or a coupling. The transmitter/path movement monitor (411,412) is at the servo motor (41), which is secured to a frame. The servo motor (41) drives at least one toothed belt (42,45). The cutting blade slide (3) is mounted to one level of a belt (45) with a positive fit. The continuous toothed belt (45) passes around two belt disks (43), each fitted with a synchronized servo motor (41). The drive transmission can be through a spindle, aligned parallel to the slide guide rail (2). A nut is moved along the spindle by its rotation, with a positive fit at the slide (3) for its movements. The servo motor can be a linear motor, with its stator as a component part of the slide guide rail (2), and the rotor is connected to the slide (3). The path movement monitor is at the guide rail (2), and the transmitter is at the rotor. A sensor (26) is at the blade slide (3) in a given position, to register the blade projection. A system is at a second given position to release the blade temporarily from the slide (3), using a limit stop (25) and a press lever (24). A pressure bolt moves the detached blade in relation to the slide (3) into a set cutting position.
