Abstract: A flat clothing for a revolving flat of a carding machine includes a foundation and a plurality of clothing tips formed from U-shaped wire hooks penetrating through the foundation and situated in adjacent rows with a row spacing between successive rows. A row offset in the direction of the length of the foundation is defined between the clothing tips in the adjacent rows such that the clothing tips are not situated one behind the other in successive rows. At least two successive zones are defined, wherein each zone has at least three rows of hooks and the row offset of the first zone differs from the row offset of the second zone. A row spacing between each row in the second zone and a following adjacent row, viewed in the fiber running direction, is different from the row spacing between the row and a preceding adjacent row.

Abstract: A clothing carrier (1) 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 (10) and is impregnated with a polymer (11). The random fiber sheet is laminated with a PUR film (12) to structurally compensate at least one surface of the random fiber sheet.

Abstract: The invention relates to a clothing for processing textile fibers, with a clothing carrier (1) and clothing tips (2), with the clothing tips (2) being formed by wire hooks (4). The wire hooks (4) are pushed through the clothing carrier (1) in a punching process. The clothing carrier (1) is a random, paneled nonwoven formed from continuous fibers or staple fibers (10) that has been consolidated by needling and impregnated with a polymer (11) having a defined specific weight per unit area and a functional layer (12) applied to a side of the clothing carrier (1) facing toward the clothing tips (2). The polymer (1) has a proportion by weight of 20 to 70 percent of the specific weight per unit area of the random nonwoven.

Abstract: The invention relates to a clothing carrier (3) for flexible or semi-rigid clothings (2) for processing fiber material, wherein the clothing carrier (3) has a longitudinal direction (6) and a transverse direction (7). The transverse direction (6) corresponds to a working direction (A) of the clothing (2). The clothing carrier (3) exhibits a maximum tensile force (FL) in the longitudinal direction (6) which is greater than a maximum tensile force (FQ) in the transverse direction (7).

Abstract: A clock recovery circuit includes a phase detector, a loop filter, a phase rotator, a predictor and a delay line. The phase detector receives an input data signal and generates a phase error signal for estimating phase error in the input data signal when referred to a recovered clock. The loop filter receives the phase error signal and determines a phase control signal based on the phase error signal. The phase rotator receives the phase control signal, and provides a phase adjusted clock based on a reference clock and the phase control signal. The predictor receives the phase error signal, and determines a delay control signal based on the phase error signal. The delay line outputs the recovered clock by delaying the phase adjusted clock from the phase rotator using the delay control signal from the predictor, and provides the recovered clock to the phase detector.

Abstract: 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.

Abstract: A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by digital circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed.
