ABSTRACT:
Cutting device for a face-to-face weaving machine, comprising a cutting knife and an upper (2) and a lower cutting rail (3) with an intermediate distance (13) which may be adjusted by means of one or several screw means (3, 7), the device comprising at least one first screw means (3) having a first (4) and a second threaded part with a mutually opposite screw thread having practically the same pitch, each threaded part (4, 5) being designed in order to move a respective cutting rail as to height in the opposite direction, because of which the almost central position of the cutting knife with respect to the upper (2) and the lower (1) cutting rail is maintained, with the same deviation, when adapting the adjusted height of the jaw to a new height of the jaw.
