摘要： A yarn tension control apparatus for tensioning a running length of yarn such as textile yarns or the like, wherein a plurality of tensioning devices form a controlled channel and are controlled by an electronic control circuit having a manually adjustable tension setting potentiometer for adjusting a circuit to provide output voltages to the tension devices of the channel adding selecting tension values to the yarn. The tensioning devices each comprise an electromagnet coil and core structure alongside which a pair of wear surface members in the form of plates or discs are supported in parallel vertical planes with the yarn running between and engaging the confronting surfaces of the wear surface members and the wear surface member located beyond the yarn plane from the coil and core structure being of magnetic material to be drawn toward the companion wear member by magnetic attractive forces to vary the tensioning of the yarn leaving the yarn tension devices. In the disc wear member embodiment, one of the discs is driven by a motor to effect a wiping action on the yarn. Degaussing circuit means are also disclosed for applying intermittent negative going pulses descending to a negative voltage level to the electromagnet coils during downward adjustment of the tension setting potentiometer to minimize residual magnetic effects.

摘要： An apparatus and method for scanning a carpet is used for detecting tuft defects in the carpet during manufacture. The apparatus or system incorporates a light source for providing light along a width of the carpet; a scanning array for detecting light from the light source passing through the carpet; and control circuit means for controlling the sensor array to scan the carpet and for receiving the output signals from the first and second sensor cells detecting tuft defects in the carpet based on the light passing through the carpet. The scanning array has at least one pair of first and second sensor cells, and is positioned opposite the light source with the carpet passing transversely therebetween. Each of the first and second sensor cells includes first and second sets of sensor elements, and an output node between the first and second sets of sensor elements. The output node outputs a signal detecting tuft defects in the carpet based on an amount of light passing through the carpet. The first set of sensor elements of the second sensor cell is positioned adjacent the first set of the first sensor cell, the second set of the first sensor cell is positioned adjacent the first set of the second sensor cell, and the second set of the second sensor cell is positioned adjacent the second set of the first sensor cell.

摘要： Automatic loom stopping apparatus for detecting yarn breakage or improper shedding defects and generating loom stop signals to be associated with a loom comprising two or three vertically spaced monitoring light beam units forming horizontal transverse light beams perpendicular to the warp yarns spanning the warp yarn path. One of the beams forms a center beam located to pass through the open shed and the other beam or beams located to be interrupted by or both of the shed sheets occupying the upper or lower limit shed positions. Detector signals responsive to interruption of the light beams by yarns are processed and applied to gating circuits and NOR or AND circuits to detect yarn breakage, broken heddles, and other shedding defects.
