  • Patent number: 5309953
    Abstract: A shed-forming device in a weaving loom which includes spaced partitions to which are mounted retention hooks controlled by electro-magnets. The electro-magnets are encased in a substantially air-tight manner between adjacent partitions. In the preferred embodiment, oppositely oriented flanges extend from the borders of each partition so as to be engagable with the flanges of adjacent partitions when the partitions are mounted in assembled relationship to thereby form substantially air-tight enclosures.

  • Patent number: 5279335
    Abstract: A device for assembling a plurality of cords which includes a bushing having a bore which cooperatively receives a clamp. The bushing includes an opening through which adhesive may be introduced after the clamp is inserted within the bore of the bushing to thereby bind the cords which are initially carried by the clamp. The clamp includes two branch elements joined by a crosspiece. Each branch element includes a first outwardly directing hooked end, a second inwardly directed jaw portion and an intermediate outwardly projecting portion. The intermediate portions are yieldably compressible with respect to one another to permit the insertion of the clamp in the bore of the bushing.

  • Patent number: 4391090
    Abstract: The invention relates to a device for pneumatically threading a yarn in a double twist spindle. It is disposed inside a sleeve connecting two tubes adapted to constitute the central shaft of a double twist spindle. A yarn brake capsule passing through the flat rod of a piston is disposed inside the sleeve, its ends abutting against the opening of the bore of one tube and against that of the central hole of an end piece mounted at the end of the other tube. When compressed air is sent into the bore of the first tube, the piston is moved, causing a lateral shift of the yarn brake capsule, thus allowing passage of the yarn along the bore of the spindle. The invention is particularly applicable to double twist spindles.

  • Patent number: 4283907
    Abstract: In a double-twist spindle comprising a shaft with a transversely elongated plate the ends of which support a rotatable annular disk, the bobbin-carrier rotatably supported by the shaft being maintained against rotation therewith by a hollow stabilizer which surrounds the shaft and which is itself rotatably mounted about an axis inclined with respect to the axis of the shaft, the first end of the stabilizer being mounted in the bobbin-carrier and the second end of the stabilizer being supported in a ring fixed to the frame and disposed on the other side of the elongated plate with respect to the bobbin-carrier, the said stabilizer having a transverse aperture for passage of the elongated plate, the connection between the elongated plate and the stabilizer is realized by non-mechanical means, as for instance by two pairs of magnets respectively fixed to the plate and to the stabilizer, the facing poles of the magnets of each pair being of selected polarity capable of generating forces which tend to maintain an

  • Patent number: 4261164
    Abstract: In a double twist spindle device wherein the support of the supply bobbin is retained against rotation on the spindle proper by two rows of permanent magnets disposed opposite each other each side of the radial passage of the yarn issuing from the axial bore of the spindle, one of the said rows is mounted in such manner as to be displaceable through a limited extent with respect to its supporting member. If the frictional torque between the spindle and the bobbin support temporarily reaches such an excessive value that the relative angular displacement of the rows becomes equal to the pitch of the successive magnets in both rows, the repulsive magnetic forces displace the said displaceable row in such manner that the undesirable accelerating effect of the magnetic forces on the bobbin support is eliminated or at least strongly decreased and that the rows may again find a new state of equilibrium when the excessive frictional torque disappears.

  • Patent number: 4237683
    Abstract: A device for delivering multiple yarns, each taken from a bobbin, comprises means for braking each yarn, other means for acting on less stretched yarns so that they advance at the same speed as the most stretched yarn, and finally a guide ensuring the displacement of these yarns parallel to one another. It may further comprise a conventional brake with elastic cheeks for each yarn, an idle drum with a non-skid peripheral coating with which the yarns cooperate before passing over a separator system.

  • Patent number: 4020774
    Abstract: In a tufting machine for making patterned pile fabric, each thread passes on two successive guiding pulleys horizontally spaced from each other and selectively displaced vertically independently from each other by the hooks of a loom Jacquard. A thread-lowering beater bar is vertically reciprocated between these pulleys in unison with operation of the machine to draw from the supply bobbin a predetermined length of thread for the formation of a pile loop by the corresponding needle of the machine, a unidirectional thread clamping device being provided between the second pulley and the needle to prevent thread being drawn from the needle itself. The length of thread thus fed to the needle at each advancing stroke of the latter thus varies as one or both of the pulleys are raised by the Jacquard. A stationary bar may be disposed at an adjustable height laterally of the pulleys to permit of altering the length of thread fed to the needle when the adjacent pulley is low.
