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: A coiler spindle for winding a band-type product such as the material coming from a continuous casting machine which includes a central shaft rotatable about an axis and having a set of adjacent segments surrounding the shaft. Each segment is mounted to slide radially on the shaft and comprises a curved plate having an external face in the shape of a cylindrical sector. The diameter of the spindle can be changed by radial displacement of the segments. Cooling of the segments is provided by the circulation of a heat exchanger fluid along each segment from a fluid box fixed to the central shaft and having at least two separate chambers. The chambers including a supply and an evacuation chamber. Each segment is provided with its own individual cooling down system arranged within the curved plate. Each individual cooling down system includes an inlet orifice connected to the supply chamber and an outlet orifice connected to the evacuation chamber.

Abstract: A turntable coiler for reeling a strip product, comprising a frame mounted rotatably around a central axis, and at least two fixed cantilever reeling mandrels, each in the alignment of a rotation shaft mounted rotatably on two spaced centering bearings. Each mandrel is connected to a motor comprising a rotor fastened to the shaft of the mandrel, and a stator. Each mandrel, its rotation shaft with both bearings and the motor form a motor-mandrel assembly mounted in an independent chassis on which are fastened the stator of the motor and both centering bearings of the shaft carrying the rotor, and the rotary frame is provided with at least two supporting devices, connected to removable bolts for centering and fastening the chassis of the motor-mandrel assembly, in a position for which the reeling axis defined by the bearings is parallel to the central axis, and each motor-mandrel assembly thus constitutes an interchangeable module.

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.
