Abstract:
A pneumatic yarn splicing apparatus 12 for spun yarns comprises a yarn quiding means 24, 25, yarn-cutting devices 22, 23, yarn end control nozzles 20, 21 and a yarn-splicing member 19. The yarn-splicing member 19 includes a flat jet nozzle 35 opened on a yarn-splicing hole 33 perforated through the yarn-splicing member 19.
Abstract:
Pneumatic yarn splicing method and apparatus for spun yarns. Suction nozzles for controlling yarn ends are arranged on both the sides of a splicing nozzle with a nozzle hole for jetting a compressed fluid. The sucking action of the yarn end control nozzle is stopped when or after the treatment of the yarn ends is completed, and then, a compressed fluid is jetted from the splicing nozzle to effect splicing.
Abstract:
A web handling apparatus for splicing the terminal end of one roll of web stock to the lead end of a second roll of web stock in an uninterrupted feed to a machine. The first roll web is fed into the machine and a second roll web in parallel relationship to the first is guided by two turning bars laterally and again in parallel and overlying relationship to the first. Thereafter a splicer device joins the second roll to the first roll. The second turning bar is pivotally mounted on a vertical axis and movable vertically such that it can be moved from below the first roll web vertically upwardly and by pivoting about the vertical axis to a position whereat the second turning bar overlies the first roll web. Subsequently, the second roll web will overlie the first web in splicing relationship.
Abstract:
In a device for splicing textile yarns by fibre-intermingling with the aid of compressed air, a pneumatic timing unit is provided for adjusting the duration of the compressed air jet. The unit essentially comprises a timing reservoir composed by a number of spaces interconnected with each other and communicating with the fibre-blending chamber, a cutoff valve controlling the flow of air from the air source to the blending chamber. An auxiliary throttling means permits to adjust with the desired accuracy the flow of compressed air from the timing reservoir to the blending chamber, so that it becomes possible to select the proper time of jet duration according to the yarn types.
Abstract:
Method for connecting an upper thread to a lower thread, which includes inserting the threads into a longitudinal groove formed in a chamber for connecting the threads with a thread feeder being movable from a thread receiving position to a thread delivery position, splicing the threads together in the chamber using compressed air acting on the threads from the side, securely holding the threads up to the application of the compressed air when the threads are inserted into the chamber uncrossed, and securely holding the threads which are inserted into the chamber during the splicing in the immediate vicinity of the chamber when the threads are crossed during movement of the thread feeder, and a device for carrying out the method.
Abstract:
Device for joining an upper thread to a lower thread by splicing, including a splicing chamber for inserting and joining the threads, a compressed air canal ending inside the splicing chamber, a thread feeder being movable from a thread receiving position to a thread surrender position for inserting the threads into the splicing chamber, thread cutting means for cutting off ends of the upper and lower threads to produce shortened thread ends, a controllable and adjustable compressed air dosing valve being connected to the compressed air canal, first pneumatic means disposed above the splicing chamber for receiving the shortened thread end of the lower thread, second pneumatic means disposed below the splicing chamber for receiving the shortened thread end of the upper thread, and suction nozzles disposed on the pneumatic means having screen-like perforated surfaces, the thread cutting means, dosing valve and pneumatic means being controllable as a function of the position of the thread feeder.
Abstract:
A hand-held splicing device for melt butt splicing thermoplastic yarns or tapes together.The splicing device comprises two-yarn clamping means, a diagonally positioned heat cutting element; means for bringing two clamped yarns in diagonal contact with the melting element and means for simultaneously lifting the severed yarns away from the cutting element and buttwise joining the melted ends together thereby fusing the yarns together. The device and mode of operation are characterized by convenience and ease of operation and afford a small strong splice especially desirable for carpet tufting operations.
Abstract:
A device for friction welding together two plastic strips which provides a weld having a strength approaching that of the strips. Movable friction jaws are oscillated on axes perpendicular to the plane of and through the strips with the result that the frictional motion is greatest in the middle of the welding zone and decreases almost to zero toward the ends of the welding zone.
Abstract:
A marine rigging apparatus for splicing new wire cable of the type having twisted wire strands to a portion of worn wire cable taken from a rotatable drum on a fishing vessel docked or moored adjacent a dock, said apparatus including a motor vehicle having a base mounted thereon, at least one bearing mounted on the base, at least one drum rotatably supported by the bearing, a hydraulic motor operatively connected to the drum for rotating the drum to wind the worn cable onto the drum, a rigger's vise mounted on the base for clamping portions of cables to be spliced with the cables being restrained against rotation about the axes of the cables, and a twister device mounted on the base for rotating one of the cables in a direction opposed its natural twist to relieve the tension in the strands of the cable at a desired location on the cable to permit an efficient and quick splicing of the other cable to the twisted cable.
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.
