  • Patent number: 6647843
    Abstract: A cutting system including a belt sleeve, a support subassembly, a cutting subassembly, an imaging subassembly, and a control system. The imaging subassembly generates an image of the actual lateral relationship between a cutting edge and a predetermined cutting location. The control system a) compares the image of the actual lateral relationship between the cutting edge and the predetermined cutting location to a reference image, b) determines deviation between the actual lateral relationship between the cutting edge and the predetermined cutting location and a preferred lateral relationship between the cutting edge and predetermined cutting location, and generates a signal indicative of the deviation. The signal is processed to reduce the deviation.

  • Patent number: 5188010
    Abstract: An arrangement for cutting thin-walled reinforced closed bands of rubber into rectangular belts having the same width is suggested wherein the closed band is tensioned between two rollers. By deflecting one of the two rollers, the closed band experiences a force component parallel to the roller fixed in position which drives the closed band against a stop. With this arrangement of the stop on the end facing toward the cutting device even thin-walled closed bands can be cut into rectangular belts with a uniformity in width not attained previously.

  • Patent number: 5083351
    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.
