  • Patent number: 8357256
    Abstract: The present invention relates to a process for the manufacture of a three-dimensional nonwoven, a manufacturing line for implementing this process and the resulting three-dimensional nonwoven product. Process characterized in that it consists in using a folding element (5) to apply, to an incoming web containing a proportion of thermoplastic fibers and/or filaments or fixing material, an initial fixing of the fold of the incoming web in the form of peaks and troughs, brought about by blades extending radially on ends of the folding element (5), this initial fixing being applied either by maintaining the folding element (5) itself at a set temperature, or by heating the incoming web. The invention is more particularly applicable to the textile industry, especially the manufacture of nonwovens.

  • Patent number: 6012205
    Abstract: A method for making a textile product from a web of fibers and/or filaments moving in a feed direction. The method comprises a pre-looping step in which the fibers and/or filaments are individually transversely looped relative to the feed direction and optionally transversely stretched, whereafter they pile up in the form of a crimped pseudo-yarn in which the fibers and/or filaments are parallelized. Prior to the pre-looping step, the method comprises a crimping step in which the fibers and/or filaments are crimped with a spacing and a depth that are a multiple of the spacing and depth of the "crimp" formed in the pre-looping step.

  • Patent number: 5575141
    Abstract: A process for breaking yarn during the automatic removal of bobbins from banks of spindles, permitting the operator to grip the end of the yarn at the base of the bobbin (1) and guaranteeing good retention of the yarn during handling of the bobbin (1), thereby avoiding premature unwinding. There is also provided a presser finger for practicing this process, comprising a blade (5) having upper and lower heels (6 and 7) respectively upwardly and downwardly inclined from the plane of the blade. The process comprises, at the end of winding, stopping winding at the lower portion of the bobbin (1), then forming a lower winding of several turns about the base of the bobbin (1) and specifically about the core of the bobbin, then rising and effecting a limited upper winding followed by a descent and breaking of the yarn below the upper portion of the bobbin (1). Specifically, the upper winding is of about one-half turn about the core above the yarn wound on the bobbin.

  • Patent number: 5546634
    Abstract: Textile machinery comprising a card having a main swift and a member which is a working cylinder or a comb, juxtaposed to the main swift and having a shaft. The distance between the main swift and the shaft is adjustable by providing a support for the shaft, the support being mounted on and for movement relative to a frame of the card. A gauge holder against which the support is adapted to bear, has a plurality of rotated positions in each of which the gauge holder imparts to the support a different position, in each of which different positions the shaft is at a different distance from the main swift. A fluid pressure jack applies the support to the gauge holder. The gauge holder is rotated by a ratchet and pawl assembly actuated by another fluid pressure jack. The gauge holder has a plurality of gauges thereon radiating in different directions therefrom, those gauges being of different lengths and being selectively engageable with the support.

  • Patent number: 5455990
    Abstract: Device for cleaning Morel cylinders of a wool card, comprising a tool carrier (1) displaceable along the Morel cylinder (2). The tool carrier (1) is mounted on a carriage (3) displaceable on a tube (4), extending parallel to the axis of the Morel cylinder (2), and comprises at one end a cleaner (5) in the form of a semi-rigid self-cleaning covering and/or rigid steel blades and at its other end a counter-weight (6). The tool carrier (1) is mounted pivotally on the carriage (3) by a shaft (7) fixed on the carriage (3), and the cleaner is flexibly urged against the Morel cylinder (2) by the counter-weight (6). The upper surface of the cleaner (5) is turned toward the Morel cylinder (2) and coacts with the spiral winding of the covering of the Morel cylinder (2) such that the rotation of this latter gives rise to an axial displacement of the tool carrier (1) and of the cleaner (5).

  • Patent number: 5307540
    Abstract: A wool card includes a rotatable Morel roller and first and second burr beaters rotatable relative to the Morel roller and relative to each other and spaced apart about the periphery of the Morel roller. The wool to be carded moves in one direction about the Morel roller and between the first burr beater and the Morel roller and then between the second burr beater and the Morel roller. The first burr beater turns at a lower speed than the second burr beater. The burr beaters have blades thereon which contact the wool to remove impurities from the wool. The number of blades on the first burr beater is less than the number of blades on the second burr beater.

  • Patent number: 5292082
    Abstract: The combination of a rotatable spindle and a bobbin receivable on the spindle for winding fibers on the bobbin. The spindle has an upper free end, and on this upper free end there is an elastically deformable drive for the bobbin, comprising a circular array of spaced resilient spring leaves. The bobbin is hollow and has on its interior a correspondingly spaced series of recesses that receive the spring leaves so that rotation of the spindle is transmitted to the bobbin via the spring leaves and recesses. The spring leaves are secured to the spindle at their lower ends and extend upwardly and radially outwardly from their lower ends and terminate in free ends that extend upwardly and radially inwardly relative to the axis of rotation of the spindle.

  • Patent number: 5016431
    Abstract: Deflection members for threads, particularly for a hollow spindle machine. The members are movable in translation by a displacement device, from a first position, during normal functioning of the machine, in which each thread (2) is no longer in contact with the corresponding deflection member, and thus with the corresponding twisting device (3), to a second position during the phases of acceleration, deceleration and stoppage of the machine, in which each thread (2) is then applied by the deflection member (1) with which it is in contact, against the corresponding twisting device (3). The thread thus receives during only these three phases, the false tension necessary to impart to it at that time constant tension and winding independent of the speed of thread travel.
