  • Patent number: 8910462
    Abstract: A plain stepped splice lay-out scheme is presented that can be used for splicing strips to one another that comprise longitudinally arranged cords. The strips can take the form of a conveyor belt, transmission belt, timing belt, elevator belt, a rubber track or a reinforcing strip. The splice is optimised for uniform bending stiffness and maximum strength retention. The cross section of the strip and the splice are substantially equal: there is no increase in thickness or width at the splice. The splice lay-out is characterised by the fact that the abutments (130)—those positions where cord ends (111, 121) meet—are positioned sufficiently far away from one another and by preference as far away from one another as possible. Preferred embodiments in terms of length common between cords of the different strips and local strength are given.

    Abstract: A procedure for splicing textile yarns mechanically whereby two yarns which are initially placed crosswise, awry or parallel to each other are first untwisted and then retwisted together by two rings, the rings being placed face to face and opposite to each other and act on yarns positioned between the rings, and whereby the excessive tail ends are eliminated and the yarns are untwisted up to a desired value in positions of mutual non-interference and are then brought together until they are substantially pressed against each other and are clamped at a position lying at about the beginning of the desired taper of each remaining tail end in cooperation with the rings so as to determine the length of the remaining tail ends and to effect a plucking/tearing action on the tails to be discharged, thereby obtaining progressive remaining tail ends before the retwisting action, and whereby the remaining tail ends are doubled and retwisted at least by the rings, which control the tail ends in at least two points locat

  • Patent number: 4539802
    Abstract: This invention concerns improvements to procedures to splice yarns (20-21), whether textile yarns or otherwise, the splice being obtained by coupling two single untwisted yarns (20-21) and by reconstituting the twists thereafter, by which improvements a part of the single yarns (20-21) is untwisted until twists of a sign opposite to the sign of the original twists have been imparted, such part then being coupled and reduced tails (220-221) of yarns being obtained, the coupled tract then being retwisted until a required twist has been imparted, the improvements envisaging that the reduced tails (220-221) are obtained after the fibers to be plucked and/or torn (42) have been made substantially parallel and after a substantially axial plucking and/or tearing action has been applied to such fibers (42), and that the taper (320-321) of the remaining reduced tails (220-221) reaches the neighborhood of the periphery of retwister rings (28), the resulting remaining tails (220-221) being controlled and positioned besi

  • Patent number: 4537019
    Abstract: A structure of a joint of spun yarns formed by lapping the tops of two yarn ends in the untwisted state and jetting a compressed fluid to the lapped portion while keeping the tops of the yarn ends free without securing the tops of the yarn ends. In at least one portion of the joint, fibers of the two yarn ends are integrated to form one yarn having twists of the same or opposite twisting direction as or to the twisting direction of inherent twists of the spun yarn.

  • Patent number: 4534160
    Abstract: In a splice between ends of multi-ply yarn, each ply end (G1a, G1b) of an end of the multi-ply yarn (Z1) is disposed adjacent to an associated ply end (G2b, G2a) of the end of the other multi-ply yarn (Z2) so as to overlap it over a predetermined length (U1, U2), and each of these two ply ends (G1a, G2b, or G2a, G1b) has the respective other ply end (G1b or G2b) of the multi-ply yarn wrapped around it in the region of overlap (U1, U2), different regions of overlap (U1, U2) of a splice being disposed in the longitudinal direction of the multi-ply yarn without overlaps.

  • Patent number: 4257309
    Abstract: Continuous filament rope and method of making same whereby high strength continuous synthetic filaments may be used to provide a rope which in use will have a strength approaching the theoretical strength of the fibers therein. The rope is made by combining a plurality of filaments and twisting the filament group into a light twine in comparison to the rope ultimately desired. The twine is then impregnated with a suitable flexible resin system and wound in a loop having at least a substantial number of turns of the twine. Thereafter the loop is allowed to twist back on itself in response to the twist initially set in the twine so as to form a rope-like center section with loops at each end thereof. Curing of the flexible resin system results in a suitable flexibility of the rope while providing for abrasion and fraying resistance. The loops at the end of the rope may be looped over hooks or pins when in use, with the resulting strength of the rope approaching that of the combined fiber strength.

  • Patent number: 4240247
    Abstract: Broken ends of a spun yarn are introduced into a hole of an air nozzle device from upper end and lower end of the hole respectively and the yarns are doubled. The doubled yarns are slightly slacked and subjected to air jetting by the air nozzle device to produce a spliced joint. The distribution of twists inherent of spun yarns is changed in the region of the spliced joint by twists imparted to the yarns by the air jet nozzle and at least one fixed portion of the new twist distribution is formed in the spliced joint.

  • Patent number: 4191009
    Abstract: A method is disclosed of splicing together two rope lengths each of which is made up of a plurality of strands individually covered with thermoplastic material. Each alternate strand of each rope length is unwound back to a predetermined point and one of the strands of the other rope length is wound in its place back to that point. This process is repeated for each of the other strands, with the respective points at which the winding and unwinding process is terminated being spaced apart along the length of the splice with respect to each other. At each of these points, the end regions of the two strands of each pair at that point are placed together and then bonded together by means of their coverings of thermoplastic material. An outer covering of thermoplastic material may then be placed over the entire splice.
