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

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 ().

The coating of the pressure roller () of a drawing roller frame for spinning frames comprises an outer layer and an inner layer fixed to the core of the pressure roller. The outer layer is thinner and harder than the inner layer and is embodied as an endless belt () which loosely surrounds the inner layer such that the belt can be displaced in relation to the inner layer. In order to improve the running of the belt, the belt is guided over a deflector rail (), the cross-sectional area (u) of the rail being wider than the average staple length of the fibre material (F) drawn on the drawing roller frame. Furthermore, the belt is designed in such a way that it comprises a double thread interlining, one thread interlining being wound counter to the second thread interlining such that the threads of one thread interlining cross the threads of the second thread interlining.

A spinning position for spinning yard from a fiber structure including a fiber guidance element is disclosed. The fiber guidance element includes a fiber guiding surface having a deflection point located in the interior of the fiber guidance element. The input direction of a fiber structure into the fiber guidance element forms an angle of inclination &#x3b1; with the fiber guiding surface at the deflection point. The splaying of the outer fibers of the fiber structure is increased and the quality of the yarn is thereby increased. The jamming of the fiber elements lying parallel to the direction of introduction may also be avoided.

The invention relates to a drafting device with twin top front rollers surrounded by aprons in which the aprons are guided around deflection members arranged above the area facing away from the clamping surface of the front roller pair. In order to achieve a low-friction, brake-free and low-wear running of the aprons, they are guided with only a slight tension around the deflection members. For this, the tendency of the aprons to assume a circular form in the circumferential direction is utilized. This tendency brings about, with the appropriately selected interval between the top front rollers and between the surfaces of the deflection members, the low contact pressure on the surfaces striven for and the low tractive tension in the aprons striven for.

A method for stretch breaking fibers to produce a staple yarn and operating a staple fiber spinning machine, and an apparatus for performing such method, that enables the production of a plurality of products of lot size smaller than a large denier tow product. The process includes at least two break zones and a consolidation zone downstream from a second break zone to form a staple yarn. The filaments are broken in a second break zone downstream from the first break zone by increasing the speed of the fiber fed into the process.

Stretch break method, apparatus and product

A spinning machine drafting device includes a pressure roller loaded against a lower roller such that a fiber structure is conveyed between the roller pair. The pressure roller has an outer circumferential layer disposed around an inner circumferential layer of different low friction material as compared to the outer layer. The outer layer is thinner than the inner layer and disposed around the inner layer so as to slide relative to the inner layer upon rotation of the pressure roller in operation of the drafting device.

Stretch break method and product

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.

A sliver compactor is provided between a drafting roller of a drafting frame and the delivery unit which supplies the sliver to the spinning stations of the spinning machine. The sliver compactor has a shielding element juxtaposed with the perforated moving surface to which suction is applied and which reduces the suction force required to draw the fibers of the sliver into a compact form. The shielding element extends over a plurality of slivers and the respective spinning stations and a number of such shielding elements may be aligned over the length of the machine below the stretching field plane and secured on the machine frame.

The invention relates to a process and to a device for the determination of the adhesion tendency of cotton by using cotton samples, whereby the sample taken from the material to be tested is opened down to the individual fiber as in the spinning process, and the fibers thus obtained are deposited on a testing surface under the influence of a certain centrifugal force in the form of a fiber ring. Following complete feeding of the sample, the deposited fiber ring is removed and the quantity of the fibers remaining caught on the testing surface is counted.
