Abstract: A medicated thread manufacturing system and associated method includes first and second slideways, a thread clamping apparatus and a medicine spraying apparatus slidably arranged on the first slideway, and a thread winding apparatus slidably arranged on the second slideway. The clamping apparatus clamps two ends of a to-be-processed medicated thread, straightens the thread and twists the thread in the straightened state into a single-strand rope state. The spraying apparatus sprays a medicine towards a surface layer of the thread in the straightened state. The winding apparatus abuts a center position of the thread in the single-strand rope state, pulls and folds the thread, and rotates the thread such that the thread winds and extends from middle to two ends to be twisted in a double-strand rope state. A control apparatus is in signal connection and/or electrical connection to the clamping apparatus, the spraying apparatus and the winding apparatus.

Abstract: An electric wire twisting device is provided, which is capable of producing a preferable twisted electric wire from a plurality of electric wires of which both ends are cut. An electric wire twisting device 1 includes a first gripping device 11 including a first clamp 2a that grips a first end of a first electric wire CT, a second clamp 2b that grips a first end of a second electric wire C2, and a first holder 15A that holds the first clamp 2a and the second clamp 2b. The electric wire twisting device 1 includes a second gripping device 12 that grips a second end of the first electric wire CT and a second end of the second electric wire CT, a first revolving actuator 3b that causes the first holder 15A to rotate around a center line of revolution CL, and a first rotating actuator 3a that causes the first clamp 2a and the second clamp 2b to rotate around a center line of rotation that is parallel to the center line of revolution CL or is inclined with respect to the center line of revolution CL.

Abstract: A rope or line having a permanent loop of fixed diameter spliced in each end thereof provides for the suspension of innumerable articles in various industries, but is particularly well suited for use in underground mining, where it may be used to support continuous miner machine cables, electric, pneumatic, and hydraulic lines, air ventilation ducts, etc., above the floor of the mine drift. The line is preferably formed of a braided synthetic fiber which has been treated to provide flame retardant properties and which is also electrically non-conductive. Treated, braided polypropylene is a suitable material for the present double looped line. The closed loops are formed by passing the first end of the line diametrically through its opposite portion, and then coaxially through that same portion and diametrically through the portion captured within the hollow braided core to secure the first end therein and to form a closed loop.

Abstract: Thread is wound between spin hooks (20) and anchor hooks (26) and around loop-pins (TP, BP) to form two thread groups, one extending between a first spin hook (20) and the anchor hook (26) and the other extending between the anchor hook (26) and the second spin hook (20). The spin hooks (20) are both rotated in the same direction, at the same speed, for separately twisting the two thread groups. Then, the two separately wound thread groups are moved laterally together and allowed to unwind and at the same time wind together in the opposite direction, to form a single fly fishing leader, or the like. The thread is wound to form twelve thread strands in a butt section of the leader, ten thread strands in a mid-section of the leader and eight thread strands in a tip section of the leader (FIG. 11). As a result, the leader that is formed tapers from the butt end to the tip end.

Abstract: Apparatus for making decorative crafts ropes including a hand-held motorized strand twisting unit and an improved method for rigging, anchoring and spreading strands. Strand twisting unit includes a frame or housing, hand grip, electrical circuit, motor, drive mechanism and twisting hooks. In the rigging process, twisting hooks are aligned and interspaced with a series of anchoring hooks on a strand anchoring unit so as to capture or snag two or more strand segments in a single motion.

Abstract: A method for twisting an elongated cord member to form a permanently twisted cord element is preferably performed utilizing an apparatus which includes first and second end units, first and second securing and twisting assemblies for securing opposite end portions of the cord member to the first end unit and for thereafter axially rotating the opposite end portions of the cord member. The apparatus further includes an intermediate securing assembly on the second end unit for selectively rotatably and non-rotatably securing the cord member to the second end unit at an intermediate point in the cord member.
