摘要： An opening roller and a process for making an opening roller for open-end spinning machines is disclosed where wavy shaped toothed rings and intermediate rings are alternately slid on a preferably cylindrical part. The toothed rings and the intermediate rings are clamped between axial stops. It is provided that during the clamping of the toothed rings and the intermediate rings between the axial stops, the intermediate rings are plastically deformed. Thus it is achieved that without narrow manufacturing tolerances, the toothed rings and the intermediate rings rest against one another without gaps so that fibers cannot be caught during use of the opening roller.

摘要： An opening assembly for an open-end spinning arrangement is provided which includes a steel alloy fitting ring element arranged on a rotatable roller body element for opening a silver into individual fibers. The fitting ring element includes a base wall having a radial thickness no greater than 2.2 mm, and includes a plurality of radially extended teeth unitary with the fitting ring element extending from the base wall. The teeth have lateral flanks formed by at least one cirumferential groove on an outer surface of the fitting ring element, and have front and back edges formed by at least two axially extending longitudinal grooves. The front and back edges have a radial height of about 0.75-0.80 times a radial height of the lateral flanks. The base wall radial thickness has a dimension of about 0.60-0.72 times the radial height of the lateral flanks. The height of the teeth is greater than the distance between the lateral flanks of axially adjacent teeth. The teeth are inclined toward a rotational direction. The teeth have an angle between the front and back edges between about 15.degree. to 45.degree..

摘要： A spinning process provides for opening at least one sliver to single fibers and for depositing the single fibers on a moving collecting surface in the form of an expanded fiber veil. During transport on the collecting surface and, if required on a moving drafting surface downstream thereof, the fiber veil is condensed, transversely to its direction of motion, to a strand. The roving-like strand is transported through a nipping line and twisted to a yarn under the action of a rotating air stream. Fiber ends are hereby spread out from the strand, which are helically wrapped around the yarn.

摘要： The fiber sliding surface and the fiber collecting groove of an open-end spinning rotor are provided with hard particles embedded therein. After a certain length of operation time of the spinning rotor, the particles in the fiber collecting groove have a larger particle size than the particles in the fiber sliding surface. Thus it is ensured that the fiber collecting groove has a better "grip effect" relative to the fibers to be spun than the smoother fiber sliding surface.

摘要： An open-end spinning rotor has a fiber collecting groove which is provided with fine roughenings. The fiber collecting groove includes additional profilings whose peak-to-valley height is at least five times the peak-to-valley height of the roughenings. This arrangement results in an improvement in yarn quality.

摘要： In the case of an open-end spinning machine, a suction roller is provided which serves to transport a fiber veil, expanding transversely to the circumferential direction of the suction roller, to a yarn formation line. The length of the transport path and the width of the fiber veil are determined by defining edges of a suction insert located inside the suction roller. At least one of the defining edges extends at least along a section of the transport path at an acute angle to the circumferential direction. Thus the fiber veil is widened in comparison to the sliver-shaped fed fiber material and/or the fiber tip at the beginning of the yarn formation line is shortened.

摘要： In a process in open-end spinning at least one sliver is opened into single fibers. A transfer surface, rotating at a higher speed than the opened single fibers, takes up same already in the opening area. The single fibers are taken along transversely to the rotational direction in the form of an expanded fiber veil. Before completion of one revolution of the transfer surface, the single fibers are transferred to a yarn forming line of a twist device, which, for example, comprises a friction roller pair, and are withdrawn, under the action of an imparted twist, along the yarn forming line thus forming a yarn. The yarn withdrawal takes place hereby transversely to the rotational direction of the transfer surface. The withdrawal speed corresponds at least to the speed of the single fibers as they arrive at the yarn forming line.

摘要： In a process in open-end spinning at least one sliver is opened into single fibers. A collecting surface, rotating at a higher speed than the opened single fibers takes up these as soon as they have left the opening area. The single fibers are taken along by the collecting surface while being expanded transversely to the rotational direction of the collecting surface in the form of a fiber veil. Before the completion of one revolution of the collecting surface, the single fibers are withdrawn from the collecting surface along a collecting line under an imparted twist thus forming a yarn, namely transversely to the direction of rotation of the collecting surface. The withdrawal speed corresponds hereby at least to the arrival speed of the single fibers at the collecting line.

摘要： In the case of a spinning machine with spinning stations preferably arranged on both sides of the machine, depositing sites for several rows of cans containing the sliver to be spun are assigned to each side of the machine while leaving an aisle. In a roof-type manner, transport devices extend over the operating aisle by means of which the slivers are taken out of the cans and are fed to the spinning stations. The transport devices have two transport sections respectively which are connected with one another by way of a deflecting guide.
