  • Patent number: 6953067
    Abstract: In order to deflect a warp thread sheet (2) in a weaving machine, a deflecting device (18)is provided which is guided in guides (26) that also guide heald frames (13, 14, 15, 16). The deflecting device positions a segment (46) of the warp thread sheet (2) that starts at a beatup line (7) of the fabric (8) between the beatup line and the heald frames.

  • Patent number: 4791481
    Abstract: A process for locating weft thread defects in woven fabrics includes using a macro (close-up) lens and video camera to produce an enlarged image of the fabric, and then observing and evaluating the weft pattern from the video generated image. Transmissive and reflecting illumination may be used on the fabric to enhance the video image. Evaluation and measurement of weft thread positions is carried out by direct visual observation or by using computerized pattern recognition systems with micro processor techniques involving digitizing the video image. A relaxation defect of weft thread is determined by measuring variation between weft thread spacing when the fabric is viewed from two different viewing angles.
