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.

Abstract: The frame of the band cutting machine comprises an arm cross consisting of four arms. Each arm supports a fabric feeding roller which is movable back and forth of the arm. The movement of the rollers is carried out by means of threaded spindles extending each through a threaded block supporting a feeding roller. The spindles are interconnected at the center of their arm cross such that a rotating of one spindle by means of e.g. a handwheel will lead to a rotating of the other spindles and accordingly a simultaneous shifting of the fabric feeding rollers along the arms. The location of the upper edge of the circular knitted fabric being cut is scanned by a photoelectric apparatus. The circular cutting knives are supported for a translatory adjusting movement in direction of their center axis. The raising and lowering of these cutting knives is controlled by the output signals of the photoelectric apparatus.
