An assembly and method for deploying, retrieving, and storing a cable having a minimum bend radius onto a drum. The assembly may comprise a frame, a rotatable drum carried by the frame, a levelwind carried by the frame, and a powertrain. The levelwind may comprise a rail spanning at least the width of the drum, and a traversable carriage carried by the rail. The levelwind may also comprise a cable guide carried by the carriage, where the cable guide comprises an elongated chute having contoured walls. The contoured walls of the chute include no bends having a radius less than the minimum bend radius of the cable. The powertrain may be operatively connected to rotate the drum about the drum axis and traverse the carriage along the rail. In some examples, the contoured walls of the chute are coated with a supplmentary coating.

A payout tube has an inner end and an outer end. The inner end is disposable in an interior of a coil of filamentary material wound in a figure-eight configuration defining a payout hole. The outer end is configured to extend outwardly from the payout hole of the coil. The payout tube has a flange at the outer end and has a rounded edge at the inner end. The rounded edge has a radius between 0.20 and 0.30 inch. In some embodiments, the payout tube includes a tubular body that extends between the flange and the rounded edge. In other embodiments, the payout tube includes an outer ring having the flange, an inner ring having the rounded edge with the inner and outer rings aligned coaxially about a longitudinal axis in spaced relation, and a plurality of pillars extending longitudinally from the outer ring to the inner ring.

The conceived invention provides both a film applicator and a method for placing a continuous film sleeve around a hose, or a grouping of a plurality of hoses. The sleeve thickness is approximately mil to 20 mils thick, which is suitable for cleanliness protection and reducing the possibility of ripping when the hoses are dragged across a floor. The embodied invention includes a plastic sleeve payout tube, that surrounds and encompasses the hose/hoses. The hoses are routed through the sleeve payout tube when they are hauled into a building to be cleaned. The payout tube stores a compacted length of an enclosing plastic sleeve, and the sleeve pays off as the hoses are dragged into the facility to be cleaned. The initial attachment of the plastic sleeve and hoses is by use of an adhesive tape or an outer clamping strap.

A helical winding unit of a filament winding apparatus includes guide members guiding fiber bundles F to a liner, a movement mechanism moving the guide members, and a rotation mechanism rotating the guide members. Each of the guide members includes two side walls and guide portions fixed between the two side walls. As the guide portions, a first guide portion having a first guide surface and a second guide portion having a second guide surface and provided downstream of the first guide portion are provided. In the height direction, the first guide surface is oriented to one side. The second guide surface is oriented to the other side in the height direction and provided on the other side of the first guide surface.

The present invention relates to a yarn tensioning system for keeping at least one yarn, which is taken from a yarn storage system to a yarn take-off system of a weaving machine, under tension. The system includes a brake roller around which the yarn is at least partially wound, and a motor for supplying a torque to the brake roller, the motor being actuable in generator operation to keep the yarn under tension between the brake roller and the yarn take-off system. In addition, the present invention relates to a weaving machine comprising such a yarn tensioning system, as well as a method for keeping at least one yarn under tension, the at least one yarn being taken from a yarn storage system to a yarn take-off system.
