  • Patent number: 5762742
    Abstract: The process for the embellishment of skins (91) comprises the following operations: application of an embellishing film (6) on a support belt (4); drying the embellishing film; coupling the skins (91) to the embellishing film after addition of a gluing material; applying pressure to the skins (91) and to the embellishing film (6); separating the skins (91) together with the embellishing film (6) which have been glued together from the support belt (4). The gluing material is applied directly to the surface (910) of the skins (91) prior to coupling skins to the embellishing film (6).

  • Patent number: 5353845
    Abstract: A shuttleless loom in which that part of the reed traversed, by the false selvedge yarns and the binding yarns for the side edges of the fabric under formation is detached from the rest of the reed. The detached part is made easily removable from the loom sley, whereas the grids of the false selvedge formation device and of the binding device are mounted on two rigid frameworks. These frameworks are easily removed through a quickbreak connection from their supports, these being driven with opposing reciprocating movement within guides fixed to the loom.

  • Patent number: 5341852
    Abstract: A taker gripper for loom use in which the weft is gripped and clamped through the combined action of two weft gripping and clamping members. These members are arranged in series along the path of the weft within the gripper. One of the members is of the elastic type and the other member is of the wedge type.

  • Patent number: 5090457
    Abstract: Device for selection and presentation of the weft yarns for high-speed looms, in which the mechanism of selection of the weft yarns comprises a set of collars, each equipped with an iron armature. The collars are slid through a free end of selectors and cooperate with a transverse lifting beam as well as with a corresponding set of permanent magnets equipped with a coil in order to nullify the magnetic field generated by the same magnet.

  • Patent number: 5046533
    Abstract: A bladed loom reed comprising a support base onto which are placed a series of preassembled packs of blades. Each preassembled pack has blades fixed to an auxiliary support and the bladed loom reed is formed by combining the packs on a support base with or without intermediate spacers between packs.

  • Patent number: 5007463
    Abstract: A weft inserter rapier for shuttleless weaving looms in which the weft clamping and retaining system comprises an elastic clamping foot the cross-section of which has a reverse-"U"-shape which is urged, due to the action of a spring-loaded lever, against two metal blades resting on two supports made from an elastomeric material. The metal blades may be provided with an upwards-protruding step at their adjacent ends inside said clamping foot, and the clamping foot can be linked by a semispherical articulated joint to a spring-loaded lever.

  • Patent number: 4957403
    Abstract: A demountable pin for rotatably connecting together two elements of small axial dimension, consisting of a bolt with a frusto-conical under-head and an inner hexagonal through bore for tightening it by a key. The pin is locked between two frusto-conical flares of the elements by an end nut with a frusto-conical under-head and a washer with a frusto-conical surface of greater taper than the flares. The under-heads of the nut and the bolt cooperate with the flares.

  • Patent number: 4884598
    Abstract: A system for instantaneously detecting breakage of a weft yarn within the shed of a multiphase loom comprising a series of closed-loop induction coils which extend in succession along the entire weaving zone to cooperate with the rotating shuttle weft yarn packages, which are provided with at least one off-centered magnetic element.

  • Patent number: 4870996
    Abstract: A gripper transportation system for a shuttleless loom, in which in the guide for the flexible tape, in a position in close proximity to the control sprocket, there is provided a transverse slot through which a solid stick of porous synthetic material impregnated with lubricating grease and/or oil passes and is urged against said tape by a spring of adjustable tension.

  • Patent number: 4763699
    Abstract: System of detection of a shed closed to passage of a shuttle in a multi-phase weaving textile loom. This invention is comprised of the following: sensitive control bars made elastically movable along the vertical direction, with a stroke at least equalling the vertical shift necessary for the shuttle roller to disengage from the corresponding thrust roller of the dragging chain of the same shuttle; two adjoining sensitive control blades, both are on the rotary-reed facing divergent side wall of each shuttle; the outward blade is fixed and rigid while the longer inward blade is rotatable around a vertical axis; and upon detection of a persistent entanglement by the control blades, a lever pin, kept in a retracted position by a retainer hook, is freed by movement of the retainer hook such that the lever pin springs outwards to protrude from the shuttle plane, pressing upon a sensitive control bar, generating a stop loom signal.
