摘要： The present invention is concerned with a process for the filtering out of fibers form an air stream, in which process a stripping blade (3), for the purpose of cleaning, is moved along the surface of a filter (2) installed in a vacuum chamber (10). A controlled linear drive (51) is applied to the said stripper blade (3), by which the stripping blade (3) is made movable for the carrying out of a two phase operational motion along a linear path of travel. The end positions are located at opposite sides outside of the surface of the filter (2) in areas (A, B) wherein the stripping plate (3) is without contact with an opposing surface. During the first phase of travel, the fibrous material is scraped from the surface of the filter (2), while during the second phase of travel of the stripping blade (3) the said fibers are pressed against the filter (2) and the stripping plate (3) essentially moves back over the fiber without taking the said fibrous material with it. The low pressure in the filter chamber (12) is measured, and upon a drip in the measured low pressure to a point lower than a specified low pressure, the stripping blade is activated at least one time to carry out the said operational movement.

摘要： An automated drafting system particularly suitable for drafting textile strands of sliver is provided. The automated drafting system includes a synchronous drive sliver drafting roller system utilizing toothed gears in the preferred embodiment operatively connecting a pair of drafting rollers with one of the rollers being directly driven by a motor to thereby cause identical rotation of both rollers. The automated drafting system also includes a system for securing and pressuring together upper and lower sliver drafting rollers wherein the lower roller of a pair of drafting rollers is preferably maintained in a fixed but rotational position while the upper roller of the pair is pressured towards the lower roller and controllably restricted as to both horizontal and vertical movement during the drafting process. A sliver autoleveling system using tongue and groove drafting rollers to sense sliver uniformity is also included in the automated drafting system utilizing linear variable differential transformers (LVDTs) to monitor vertical displacement of the upper roller of a roller pair relative to the lower roller. The automated drafting system further provides a feed-forward and feed-back autoleveling system for control of sliver drafting rollers utilizing an input sliver sensor and an output sliver sensor communicating with a computer to facilitate sliver uniformity. A draftless sliver coiler packaging system is still further provided by the automated drafting system and utilizes a sliver level sensor to controllably and automatically adjust the speed at which sliver is packaged subsequent to emergence from a variable speed sliver delivery system.

摘要： An autoleveller derives the signal for its draft correction from an averaged value of the sliver weight or thickness signals in each of a plurality of unit lengths of the sliver path. A preferred embodiment uses upstream and downstream sliver weight or thickness measuring means to derive signals for a draft correction and the gain of a draft correction made in response to the first sliver measuring means is varied in response to the averaged signal from the second sliver measuring means.

摘要： A compact carding apparatus is disclosed which includes a pair of upstanding carding cylinders (B) and (C) carried in a self-standing manner on a base frame (260). Cylinder (C) is carried generally atop cylinder (B) by mounting plates (272, 274) which allow radial movement of cylinder (C) to yield to large lumps passing between the cylinders. A chute feed (10) and coiler (192) are uniquely combined with the component arrangement in a minimum of space and in a mobile construction so as to permit movement of either the chute or coiler away for access to the apparatus. The compact upstanding arrangement provides for mounting of a number of carding elements mounted about the two cylinders which include stationary plates (40, 42, 44, 46) on cylinder (B); and revolving flat assembly (E) and stationary carding plates (96, 123) on cylinder (C). An extended fiber path (P) is defined about cylinders (B) and (C) along which a transferred fiber mass may be effectively exposed for carding on both of its sides. Fibers may be subjected to a carding action over approximately 80 percent of the circumference of the carding cylinders. Automatic thread-up of a sliver produced on the carding apparatus is provided by perforated transport belts (150, 152) which collect a web (W) and condense it into sliver (S). Sliver (S) is subjected to excessive drafting by a pair of transfer rolls (168, 170) driven at a high relative speed. During excessive drafting, fibrous parts are pulled and separated from a start-up sliver to form a pointed end. The fibrous parts are removed by suction (184). Excessive drafting is terminated and the pointed sliver end is fed to an air trumpet (174) in which the sliver is condensed and fed to a pair of metering rolls (188, 186) for delivery into a coiler tube (190).

摘要： A process of producing slivers for open-end spinning of wool or synthetic yarn and being characterized by eliminating the necessity for repeated doublings and draftings of the sliver while providing the desired uniform fiber distribution and weight in the sliver and yarn. Stock material is carded, then cross-lapped to reorient the fiber distribution, and again carded for producing a fiber web. This web is divided into relatively narrow rovings or strips of fibers and oriented into groups containing alternate strips of fibers from across the width of the fiber web. The respective strips of fibers from each such group are combined and formed into a sliver.

摘要： A sliver guide for guiding a plurality of textile slivers in an entry region of a drawing frame, includes a first guide portion for guiding a first group of textile slivers, and a second guide portion for separately guiding a second group of textile slivers. In a side view of the sliver guide, the first guide portion and the second guide portion are spaced apart from one another. The sliver guide has a third guide portion spaced apart from the first guide portion and from the second guide portion. To at least one of the guide portions, lateral guide elements for laterally guiding textile slivers are assigned, wherein the mutual distance of the guide elements can be adjusted.

摘要： In order to control cotton fibre fluctuation between the compactor device (5) and the drafting unit (6) within a card (1A), the drafting unit (6) can be moved (either along a rectilinear trajectory and/or along a circular trajectory) between a first position (L) coinciding with its maximum distance from the compactor device (5) and a second position coinciding with its minimum distance from said compactor device (5) until said distance is reduced to the minimum possible. The distance between the drafting unit (6) and the compactor device (5) varies in a manner inversely proportional to the operating speed of the card (1A). In an alternative embodiment: a support and guide element (40) for the web (9) is positioned between the doffer (2) and the pair of rollers (7, 8) of the compactor device (5); a conveyor device (24) is interposed between the compactor device (5) and the drafting unit (6) (FIG. 2).

摘要： An automatic startup device includes a roll assembly for discharging the fiber web; a web transporting arrangement situated under the roll assembly for gathering and advancing the web; and a trumpet situated under the web transporting arrangement. The trumpet has separable parts between which the web in introduced. In a first position the two trumpet parts are at a relatively large distance from one another, whereby the web is discharged by the trumpet in a substantially unaltered state and in a second position the two trumpet parts are at a relatively small distance from one another, whereby the web is compressed and discharged by the trumpet as a sliver. There are further provided a web delivery arrangement under the trumpet for receiving and removing the web; and a calender roll pair arranged under the trumpet for receiving and advancing the sliver discharged by the trumpet.
