    摘要: A method for converting a multifilament bundle of a synthetic material into a sliver and an apparatus for effecting the method. The apparatus comprises: a feed roller device for feeding the bundle; a draft roller device consisting of a pair of draft rollers, the peripheral speed of which draft roller device is higher than that of the feed roller device, for stretch breaking the filaments in the bundle between the feed roller device and the draft roller device; and an apron belt, belted between one roller of the draft roller device and the intermediate portion of the feed roller device and the draft roller device, which is wound around the other draft roller. The broken filaments are smoothed between the apron belt and the other draft roller so that the evenness of the sliver thickness is improved and the uniformity in quality of the spun yarn obtained from the sliver is also improved. Accordingly, the method and apparatus has advantages when a multifilament bundle of a synthetic material is converted into a sliver at a high speed of not less than 200 m/min.

    摘要: A zero twist, staple fiber yarn of good strength, outstanding cleanness and good uniformity is produced from continuous filaments by a direct spinning process followed by entangling to a pin count of less than 50 millimeters. Filaments of less than 70 percent break elongation are stretch broken to fibers having an average length of 18 to 60 centimeters with at least 5 percent short fibers, at least 1.5 percent long fibers, and 50 to 93.5 percent fibers of lengths between 12.7 and 76 centimeters.

    摘要: In accordance with the invention, the breaking and stretching machines have pressure heads, each one being essentially constituted by two opposed complexes, upper and lower, each one of which includes at least two transmission chains of the Renold type which are meshed with two chain pinions (double, triple, etc) fitted on two strong parallel shafts that are supported by appropriate bearings attached to the lateral elements of the machine bedplate; those corresponding to the lower complex are fixed, while those corresponding to the upper complex are moveable, so that the latter complex may adopt, with respect to the other complex, two limiting positions; one of separation, which permits the introduction of the layer of fibres, and the other, where the elements approach one another, to be utilized during the work and in which the pressure can be adjusted.
