In the case where a textile yarn is continuously pressed using a nipping roller, the pressure to be applied to the textile yarn is preferably adjusted to a value of in gmeter count or more, where represents the sum of the meter count of the textile yarns applied to the nipping roller jan 01, 2019 the rubber hardness, type of fiber, nip pressure, roller diameter, and speed of the machine decides the amount of wet pickup the water imbibition values are different for different fibers and fabrics and are partially related to the low wet pickup of different fibers.

sep 14, 2009 the control roller against the counter pressure roller. the web edge is controlled by roller offset and nip pressure. for more accurate edge guiding, a built-in broadband sensor with web edge fluctuations up to mm is available due to the large scanning range 120 mm the amount of pressure may be kept equal in all rollers or it may be different for various drafting rollers. the amount of pressure is set precisely to get optimum performance of simplex machine. pressure more than required causes damaging the fibres while less pressure affects the uniformity of roving and increases the unevenness percentage of
feb 03, 2012 polyurethane foam from a supply roller is passed over a gas flame at around and combined with the textile material from a second roller in the first nip of a three-bowl syste. the foam-laminated textile material is then passed through the second nip and wound up on a third rollerpneumatic pressure head for the drafting rollers. this technology can control the pressure for sliver automatically and from that better fiber control can be achieved. tension measuring system when the card sliver is fed to the draw frame, there is a long path to travel. So on way there will be tension variations due to friction forces and
