摘要： The invention discloses a method of dynamically configuring linear density and blending ratio of yarn by two-ingredient asynchronous/synchronous drafted, comprising: a drafting and twisting system, which includes a first stage drafting unit, a successive second stage drafting unit and an integrating and twisting unit. The first stage drafting unit includes a combination of back rollers and a middle roller. The second stage drafting unit includes a front roller and the middle roller. Blending proportion and linear densities of the two ingredients are dynamically adjusted by the first stage asynchronous drafting mechanism, and reference linear density is adjusted by the second stage synchronous drafting mechanism. The invention can not only accurately control linear density change, but also accurately control color change of the yarn. Further, the rotation rate of the middle roller is constant, ensuring a reproducibility of the patterns and colors of the yarn with a changing linear density.

摘要： A yarn, especially a sewing thread or an embroidery thread, is described, which has the structure of a core yarn with at least one core consisting of multifilament yarns and a spin over of staple fiber yarns. At least one portion of the fibers, which build the staple fiber yarn of the spin over, is bound between the filaments of the at least one multifilament yarn of the core over its total axial fiber length or over a section of its axial fiber length. Furthermore a method to produce this yarn is described.

摘要： A spinning machine having a drafting frame, a condensing unit at the downstream side of the drafting frame and a spinning station for winding up the yarn and imparting twist to the roving in forming the yarn. The condensing unit comprises a disk-shaped suction rotor oriented in a plane tangent to the output rollers of the drafting frame. A limited compaction zone is formed by a shield within a suction rotor and designed to apply suction only to a limited portion of the perforated periphery thereof. The pressing roller bears against the suction rotor at the downstream side of the compaction zone.

摘要： Described are thread-guiding components for apparatus for producing, treating and processing fiber materials, having a surface which comes into contact with the fiber materials defined by certain values of the maximum averaged roughness depth R.sub.z and the values of the load-bearing proportion calculated for certain depths of cut. The defined surface comprises a cermet material. Preferably there is additionally deposited on it an outer layer, from 0.1 to 10.0 .mu.m in thickness of nitrides and/or carbides of titanium or chromium. The components are notable for significantly enhanced long-term stability of the surface properties. The components are preferably godets.

摘要： In order to avoid the need for providing expensive fine rovings, a process is proposed in which two rovings are supplied to respective ring spinning stations (3). A common primary roving (2) is drawn and is subsequently divided into two separate rovings (2a, 2b) for feeding respective ring spinning stations (3). The primary roving (2) is divided into two separate rovings (2a and 2b) by conveying means (11), which comprise two juxtaposed suction zones (12a, 12b), which extend in the direction of conveyance.
