A clothing carrier () for flexible or semi-rigid clothings is formed from a random fiber sheet consolidated by needling. The random fiber sheet is formed from PES or PA fibers () and is impregnated with a polymer (). The random fiber sheet is laminated with a PUR film () to structurally compensate at least one surface of the random fiber sheet.

Clothing carrier

A method improves a winding process of a textile machine and a winding station of a textile machine having a machine controller (), a yarn sensor (), a yarn quality monitor, in particular a yarn clearer (), and a yarn connecting device, in particular a splicing device (). A yarn () is wound onto a bobbin (). The yarn () is analyzed with regard to its length, quality, and/or speed, and is cut if necessary in order to clear a quality defect and two yarn ends are connected to one another by means of the yarn connecting device after the quality defect has been removed. The yarn () is analyzed with regard to foreign material, yarn speed, and/or yarn length by means of a capacitive yarn sensor (), and is analyzed with regard to the yarn body and the yarn characteristic by means of an optical yarn quality monitor. The yarn () is subsequently optionally cleared. Data of the capacitive yarn sensor () with regard to the foreign material and/or the yarn speed is provided to the yarn quality monitor, in particular the yarn clearer (), and with regard to the yarn length and/or the yarn speed are provided to the machine controller ().

Method and winding station for improving a winding process of a textile machine

The invention relates to a method for monitoring the quality of a yarn on a textile machine, wherein the yarn passes a monitoring unit of the textile machine, with the aid of which at least one measured variable (M) which is dependent on a physical parameter of the yarn is determined, and wherein the measured variable (M), or a variable derived therefrom, is evaluated with respect to the position thereof with regard to at least one reference value (R). According to the invention, it is proposed that the selection of the reference value(s) (R) takes place taking into account one or more characteristic variables of the yarn, said characteristic variables being yarn-specific and defined prior to evaluating the measured variable (M). Furthermore, a textile machine is proposed which comprises at least one monitoring unit for monitoring at least one physical parameter of the yarn, and at least one controller which is operatively connected to the monitoring unit. The textile machine is characterized in that the controller is configured to monitor the yarn quality according to one or more of the preceeding claims.

Yarn monitoring method

The invention relates to a clothing carrier () for flexible or semi-rigid clothings () for processing fiber material, wherein the clothing carrier () has a longitudinal direction () and a transverse direction (). The transverse direction () corresponds to a working direction (A) of the clothing (). The clothing carrier () exhibits a maximum tensile force (F) in the longitudinal direction () which is greater than a maximum tensile force (F) in the transverse direction ().

Clothing carrier for clothing for processing fiber material

The present invention relates to a device, such as a carding machine, for processing fibers, said device comprising a cylinder, which is provided with a lining, and at least two carding segments which are arranged one after the other in the direction of rotation at least over an area of the circumference of said cylinder, each of said carding segments being provided with a toothed lining. The present invention aims at improving the efficiency of such a device especially in terms of fiber parallelization. In order to achieve this, the toothed linings of the carding segments are designed differently; when the fibers are engaged by the toothed lining of the carding segment constituting the upstream carding segment in the direction of rotation, the resultant influence on an individual fiber entrained by the circumference of the cylinder will be equal to or more intensive than the influence exerted when the fibers are engaged by the toothed lining of a carding segment constituting a downstream carding segment in the direction of rotation.

Device such as a carding machine for processing fibres

The present invention relates to the application of fiber length measurement in the blowroom or carding room of a spinning mill. A method and an apparatus in a textile processing machine are described in which before and/or after a working element of the textile processing machine the nep count and/or the fiber length (staple) is determined, with an open-loop/closed-loop control unit being provided which receives the values for the fiber length and/or the nep count as input and determines therefrom the optimized machine setting data and outputs the same to at least one actuator of a working element which influences the nep count and/or the staple of the textile processing machine.
