| 156425000 | Longitudinally progressive helical winding means | 7 |
| 20090038759 | Filament Winding Automated System - The present invention makes it possible to increase production efficiency while reducing costs. A filament winding automated system according to the present invention includes a winding device winding a fiber bundle R paid out from a head portion | 02-12-2009 |
| 20090126875 | Filament Winding Apparatus - A filament winding apparatus efficiently performs a helical winding process in which the winding angle of the fiber bundle differs. A helical winding head includes two guide rings, adjacently arranged along an axis center of the mandrel, and guide tubes arranged at equal intervals along a circumferential direction of the guide rings. The guide rings are switchable between a first state in which phase positions of the guide tubes are matched and a second state in which the phase positions of the guide tubes are evenly shifted in the circumferential direction by a phase switching structure. Tube exits of the guide tubes are arranged close in the first state. | 05-21-2009 |
| 20120312477 | Winder for Rectangular Cross-Section Wire - A device is provided for winding wire into a coil. The device includes a shaft for turning on an axis; a hub attached to the shaft; inner and outer wheels; a mandrel having an outer radial surface for looping the wire; and a guide connectable to the mandrel and extending past the inner wheel. The shaft is structurally supported by a housing. The inner wheel, mandrel and outer wheel are removably fastened to the hub, the wire passes along the guide and lays along the radial surface of the mandrel, and the shaft rotates for looping the wire around the mandrel. The shaft can be rotated either manually or by a motor. A system is provided that includes the winding device, and further includes a wire-feed device, particularly for arranging several strands of wire into a ribbon. | 12-13-2012 |
| 156428000 | Forming and/or covering indefinite length article | 4 |
| 156429000 | Rotating core or mandrel | 1 |
| 20100126670 | APPARATUS FOR MANUFACTURING EXTRUDED COILED TUBES FOR MEDICAL PURPOSES - An apparatus for manufacturing extruded coiled tubes for medical purposes is provided which includes rotary shafts protruding from a spindle, each rotary shaft being coupled to a respective flexible shaft resting on a series of supporting elements substantially equidistant to each other and supported by a main central shaft; at least an extrusion head to extrude a ribbon, and at least an extrusion head to extrude a rib; the ribbon and the rib being co-extruded, side by side, and being wound on an ideal surface formed by the external surfaces of the flexible shafts. The apparatus is characterized in that for changing the pitch with which the rib is wound on a base tubular element, formed on its turn by the winding coil of the ribbon, at least two twisting bars operated by a crank are used to rotate the supporting elements with a pre-defined angle. | 05-27-2010 |
