ABSTRACT:
By means of a bracket located above the turntable the twisting of the textile article threaded through this bracket can be scanned and measured by a feeler means. Upon the twisting the bracket will rotate by a certain angle. If a preset angle of rotation is exceeded, the feeler sends a control signal to the control apparatus. This control apparatus controls the relationship circumferential speed feeding cylinders to rotational speed turntable. By means of such controlling an extremely fine regulating can be made, which may be necessary, for instance, due to the slip between the tubular textile article and the feeding cylinders. The upper edge of the textile article being cut is scanned by means of at least one scanner. The location of the scanning is preferably between the final feeding cylinder (seen in direction of movement of the textile article) and the cutting tools of the cutting apparatus. The emitted signals of this scanner are led to an adjusting device which controls the stroke of the oscillating jacket members of the feeding cylinders. By means of this controlling arrangement, namely on the one hand the controlling of mentioned relationship and on the other hand of the strokes of the jacket members of the transporting cylinders, bands having set widths can be cut with a large precision.
