摘要:
Method and apparatus for an assembly which is attachable to a skid-steer or similar front end loader or tractor which is used to install fence wire, including woven wire. The assembly contains a plurality of spindles upon which rolls of wire can be placed, which wire passes through a threader which organizes and separates the wire, then through a clamping device operated hydraulically using electric and hydraulic controllers, then over a roller and around an upright wire guide whereupon the wire is attached to a fence post in a conventional manner. The wire is clamped using a clamping member operated by a hydraulic cylinder to clamp and lock the wire so that the wire can be stretched by the engine powered skid-steer, front end loader or the like so that the wire can be tightly attached to each fence post in a series operation. The plurality of spindles is disposed on an upright central stanchion attached to a platform so that the wire can be easily placed on and removed from the spindle. An alternative embodiment is shown for use with woven wire.

A system for adjusting a path of a wire includes a precast pulley assembly having at least one precast pulley having at least first and second positions. The at least one precast pulley may be adjustable from the first position to the second position without a user touching the at least one precast pulley. A path of a wire is adjusted when disposed around the at least one precast pulley when it is in the second position instead of in the first position. In one embodiment, the precast pulley assembly includes first and second precast pulleys disposed in an adjacent relationship with respect to one another, wherein a wire can selectively pass over one or both of the first and second precast pulleys.

Disclosed is a drive wheel set, comprising a common shaft and at least two external rotor motors installed on the common shaft. External rotors of the external rotor motors form drive wheels of the drive wheel set. Also disclosed are a vertical-type wire storage frame, a swing-type wire storage frame, a guide wheel frame, a traction mechanism and a multi-path conveying mechanism using the drive wheel set. The drive wheel set is small in size, occupies less space, and is suitable for a situation where a plurality of motors need to be driven but sufficient space is lacking.

A yarn delivery device has a casing, a delivery drum rotatably mounted on the casing, a drive belt, at least one drive wheel propelling the delivery drum, the drive wheel having a peripheral section for application of the drive belt and being provided with at least one cleaning channel extending in a peripheral direction, and at least one scrapper attached to the casing and projecting at a point of a peripheral section remaining free of the drive belt into the cleaning channel.

The thread feeding wheel is capable of preventing static-electricity from being produced due to rapid feeding of the thread and which provides a surface having a low frictional coefficient so that the thread feeding around the thread feeding wheel would subject to minimal frictional damage. The cylindrical body is made of an aluminum alloy. A layer of oxide of the aluminum alloy is formed by a hard anodizing process on the middle portion of said cylindrical body. A layer of polytetrafluoroethylene resin is impregnated over said oxide layer to further reduce the frictional coefficient of the thread running surface.

The drawroll unit has a heatable galette in which the shaft of the gallette is mounted in bearings which, in turn, are mounted via vibration damping devices in a stationary housing. The vibration damping devices may be in the form of bodies of interlaced wire, O-rings or the like. The vibration damping devices serve to damp vibrations of the shaft in a critical speed range within the normal speed range of the rotor so that the galette can be operated at any speed within the normal speed range.

A slip-proof elastic yarn-feeding ring device removably fitted to the circumference of a yarn-feeding drum whereby a yarn is pressed between a yarn-feeding belt and the ring device and steadily forward carried by the yarn-feeding belt without slipping movement. The diameter of the ring device is smaller than that of the yarn-feeding drum so that when the ring device is extended to ring the yarn-feeding drum, the ring device closely binds a portion of the circumference of the yarn-feeding drum via its elastic binding force.

Yarn 10 is fed from a package 11 to a point of knitting 12 on a knitting machine along a substantially closed path defined by tubing 13. Adjacent to a positive feeding device 14, the tubing 13 includes a section 15 which can be closed for initial blowing of the yarn through the tube, and opened to allow threading of the yarn 10 around the feeding device 14. This facilitates initial feeding of the yarn to the knitting machine, and also helps in the control of loose fly or lint generated from the yarn 10. The section 15 includes a tensioning device (30, not shown) for the yarn.

A pre-take-up roller mechanism is provided for varying the tractive force and tension on running thread being wound by a take-up mechanism in a thread processing machine. The mechanism includes a variably driven rotating drive shaft carried by the machine, a thread pre-take-up roller rotatably mounted on the drive shaft for receiving the running thread on the surface thereof and for being driven by the running thread through adhesion, and an eddy current clutch or a combination eddy current and hysteresis clutch operatively connecting the drive shaft and the pre-take-up roller for varying the torque on the pre-take-up roller and thus the tractive force and tension on the running thread by varying the driven rotational speed of the drive shaft without affecting the constant winding speed of the running thread being wound by the take-up mechanism.

A winch drum (1) is designed to operate without fleeting knives.The winching surface of the drum (1) is made up of fingers (6) which reciprocate axially along the drum (1) during use. The design is such that, in use, a major proportion of the fingers (6) are always moving in the same direction along the drum (1). This has the effect that the turns of an element being winched are both spaced and continuously progressed along the winching surface of the drum (1).The invention has particular application in the laying and taking up of submarine optical fibre cables.
