Abstract: A bow spreader bar employed in a plastic film processing arrangement incorporates an extruded member and a low-friction plastic wear cover. The bow spreader bar is positioned in advance of the film take-up roll and presses into the film web to eliminate folds, wrinkles, or creases. The extrusion can be of aluminum or another light-weight material having a T-shaped profile that is rounded on a side that faces the film so that the extrusion has an arcuate front surface. The associated wear cover is made of a wear resistant plastic material and is disposed on the arcuate surface of said extrusion. Preferably, the extrusion is formed with one or more tubular portions and can be fitted for fluid cooling. The arcuate surface of the extrusion can be provided with a low-friction surface treatment.

Abstract: Wire rings or coils in tubs pass from a cooling conveyor onto a rotatable framework in which the tub carrier can be raised toward a transfer conveyor. The framework is then tilted to deposit the wire ring on the transfer conveyor, whereupon the tub is raised to liberate the wire ring which is displaced onto a conveyor for a subsequent processing station. The framework is rotated again through 180.degree. to align the empty tub with the return conveyor.

Abstract: An attachment structure for a tape body which supports, on reel hubs, a tape body such as a leader tape, etc. to which a magnetic tape is connected. This attachment structure comprises a tape reel provided with a reel hub which takes cylindrical shape provided at the central portion thereof and a clamp member attached to the reel hub, and a tape body connected to the reel hub in the state where the end portion is supported by the clamp member and wound on the outer circumferential surface of the reel hub. The tape body supported by the reel hub is such that the base end portion side serving as root portion of the drawing side from the reel hub is deformed in the winding direction onto the reel hub following the outer circumferential surface of the reel hub. Deformation of the tape body is carried out by thermal deformation or pressure deformation, or thermal deformation and pressure deformation.

Abstract: An electrical cable management device for use in mining and other applications where there are size restrictions on equipment. The device is a round stationary drum, around which travels a carriage for winding, unwinding and storing hot electrical cable. The device is mounted on skids and is portable and can be located away from the mining activity while still being able to manage and control the winding and unwinding of electrical cable in response to movement of the mining equipment. The device does not require electrical split ring connectors, rotating collector rings, brushes or the like, but provides a continuous cable from a power source to the moveable mining equipment. The orbiting carriage is driven by an electric motor for winding cable and automatically becomes free wheeling when cable is unwound from the drum.
