job is doubled, in particular for the twisting of the glass strands

摘要

To maintain a speed determined of the wire in a doubling crafts without conveying elements special moving the wire has a speed determined, each work station of a doubling job is provided a measuring device responsive to the actual speed of the wire and which, by means of a regulator, varying the speed of rotation of the driving of the supply reel, which determine the speed of the wire in the addiction of its diameter of running, such as a speed that of the wire is respected. / p & & p & different vertical speeds of the wire can be implemented at regulator by a programmer. The output signal of the measurement device may also be used to measure and to indicate the length of wire which passes. A sensor is also made for the speed of rotation of the supply reel and emet a signal of the wire breaking, when this speed exceeds a maximum adjustable.
