Aspects of the present invention relate to a rope dispensing device for delivering elongated material such as rope, wire, or hosing and generally has a mounting frame operatively coupled to a material feeding device comprising a wheel and pinch device, an adjustable shroud, and a stabilizing device. The elongated material is received into the material feeding device from a first location and driven through the rope dispensing device by the wheel to be output at a second location. The adjustable shroud may be positioned about the periphery of the wheel so as to direct the output elongated material from the rope dispensing device. The invention is at least partially supported by the stabilizing device operatively coupled to a body of a user. Additionally, the stabilizing device is extendable, collapsible, and detachable allowing the invention to take on a more compact form for easier storage and/or transportation.

The wire feeding device that feeds welding wire W from the wire source to the welding torch is disposed between the wire source and the welding torch and is configured to temporarily accommodate the welding wire W fed from the wire source and to feed the accommodated welding wire W to the welding torch. In the case where feeding of welding wire W is abnormally stopped, if the acceptance unit accepts instructions for increasing or decreasing, the wire feeding device controls the speed of feeding welding wire W fed by the first feeding part or the second feeding part so that a difference is generated in the feeding speed of the first feeding part and the second feeding part and the accommodated amount of welding wire W is in a range from the lower limit of normal to an upper limit of normal.

A wire feeding system, in particular for feeding a so called cold wire or wire with no tension nor signal running on its surface, in which the pulling or holding of the wire by the front wire feeder puts the rear pushing slave booster respectively into a pre-set active full motor torque or into a pre-set stand-by minimum motor torque, as needed. Alternatively, a wire feed system for feeding a so called cold wire or wire with no tension nor signal running on its surface, in which the rear pushing slave booster is remotely controlled by an optic sensor positioned nearby the torch and sensing the light of the torch welding or spraying arc.

A self-actuating tension head for a strapping machine for feeding a steel strapping material around a load, tensioning the strapping material and sealing the strapping material to itself has a tension wheel biasing element. The tension head includes a body defining a strap path therethrough, a drive wheel, a tension wheel and a pinch wheel. The strap path extends between the tension wheel and the pinch wheel. The drive wheel is a fixed distance from the tension wheel. The drive and tension wheels are operably engaged with one another. A pivoting link operably connects the drive and tension wheels. The link pivots about the drive wheel axis of rotation. A cam is operably mounted to the tension wheel, and engages a cam follower to pivot the link to move the tension wheel into and out of engagement with the pinch wheel. The tension wheel biasing element cooperates with the cam to maintain the cam in a position relative to the cam follower.

A wire outlet nozzle arrangement includes a plurality of wire outlet nozzles situated in parallel with one another. Each of the wire outlet nozzles guides a winding wire in a wire feed device, wherein the wire outlet nozzles include an outlet opening, through which the winding wire guided in the wire outlet nozzle exits the respective wire outlet nozzles. The wire outlet nozzles are mounted so as to be at least partially movable in a direction perpendicular to the wire feed direction.
