Abstract: A yarn processing system including a feeding device, a power loom, a controllable yarn tension device which is situated downstream from the feeding device, and a tensiometer which supplies a signal that represents the yarn tension and which is arranged downstream from the yarn tension device. The tensiometer includes a separating device which can be adjusted between a passive position and a separating position and with which a temporary separation between the tensiometer and the weft yarn can be effected in order to generate a zero yarn tension signal for a signal analysis device. In addition, the weft yarn is temporarily separated from the tensiometer probe during the interval between successive insertion operations, and a calibration is carried out for a future control operation by using the zero yarn tension signal.

Abstract: A slide fastener stringer having a plurality of coupling elements molded from synthetic resin monofilament woven in a fastener tape in succession along a longitudinal edge thereof, at the same time when the fastener tape is woven, with a plurality of element row binding warp yarns running in parallel to each other. At least two adjacent element row binding yarns disposed on a side toward coupling heads of the coupling elements run over upper and lower leg portions of the coupling elements in the longitudinal direction of the tape, and then run under a foundation weft yarn running below an adjacent coupling element and that adjacent coupling element. Each of the two adjacent element binding warp yarns is woven in this repeating pattern, which suppresses floating of the binding warp yarns after a space portion is formed.

Abstract: A reed in a loom is driven or oscillated back and forth to perform the beat-up motion by a direct reed drive that avoids using the main loom drive for operating the reed. The direct drive is an electromagnetic motor which uses as one of its components a reed support shaft (4) either as a rotor or as a stator. The reed support shaft acting as a rotor carries a reed slay which mounts the reed to the rotor. When the reed support shaft acts as a stator, the reed slay is mounted to separate rotor elements. In both instances the reed support shaft is part of a rotary or linear electromagnetic direct drive motor construction.

Abstract: At least one of two flexible leaf springs that form a thread gap is controlled by a linearly moveable element of a linear motor or drive. Multi-thread brakes are formed by assembling a plurality of such brakes on a common support whereby a single stator may cooperate with a plurality of linearly moveable armatures forming a corresponding plurality of thread brakes or each thread brake may have its own stator and its own armature arranged in a row either linearly or along a curved support, whereby a compact structure is achieved.

Abstract: To improve the breaking of a roving between a pressing finger bed and a fully wound bobbin preliminary to a bobbin change, the roving is initially wound around the tube above the upper cone and an unwound roving reserve is formed from at least a half turn on the upper winding cone and the body. A false twist is generated to provide a weakened region so that the roving has a first segment extending from the upper edge of the upper winding cone to the lower edge thereof, a second segment extending to the weakened zone and a third segment extending from the weakened zone to the pressing finger bed. The false twist increases the number of twists per unit length in the first segment and decreases the number of twists per unit length in the second and third segments. The pressing finger is moved along the bobbin periphery and the roving is broken at the weak spot by further movement of the pressing finger relative to the bobbin.

Abstract: A disposable absorbent article is provided which includes a substantially liquid-impermeable outer cover, a liquid permeable bodyside liner, an absorbent body located between the outer cover and the bodyside liner, and a pair of fasteners located on the laterally opposed side edges in one of the waist sections of the absorbent article. The outer cover can be configured to provide a substantially permanent deformation of at least about 10 percent when subjected to a tensile force of 100 gmf per inch (per 2.54 cm) of width according to the Material Elongation and Deformation Tensile Test set forth herein. The outer cover can further define a water vapor transmission rate of at least about 800 g/m2/24 hr. The permanent deformation of the outer cover in use can result in a lateral breathability gradient ratio between the outer cover in the waist section and the crotch or intermediate section of the article of at least about 1.25 according to the Product Deformation Test set forth herein.

Abstract: A regulator works with a thread or yarn supply which is intended to provide a draw-out length of the thread or the yarn which is dependent on the one hand on the size of the supply and on the other hand on an assumed or adjusted thread tension in the draw-out thread or the draw-out yarn. A load cell is arranged so as to sense the actual thread tension in the drawn-out thread and to, supply to the regulator information for changing the size of the thread stock when the actual thread tension deviates from the assumed or previously adjusted thread tension (the desired value). The load cell can also function as a pick monitor.

Abstract: Ground warp and pile warp thread sheets are supplied to a shed forming device. The ground warp and the pile warp are separately deflected over a deflecting rod upstream from the shed forming device. The deflecting rod supports the ground warp and directs the pile warp to cross and interpenetrate through the ground warp before deflecting the pile warp into the back shed. The deflecting rod is positively driven and controlled to pivot about a horizontal axis to provide a positive controlled partial compensation of the pile warp thread length variations. The pile warp also runs over a pile warp thread reserve and compensating device upstream from the thread crossing location to provide an additional passive uncontrolled compensation of the pile warp thread length variations and to provide a pile warp thread reserve during the pile loop formation and/or the shed changes in the weaving process.
