摘要： A fastening device for a polishing paper cloth of a portable polishing machine. The device comprises an attaching portion which can be detachably attached to a base plate of the polishing machine and a fastening device main body for winding the polishing paper cloth thereon to engage therewith. Multiple concave grooves, which are continuous in the winding direction of the polishing paper cloth in parallel, and a cavity portion formed inside are provided. Therefore, by giving flexibility to the main body to allow it to be deformed in many directions, it is possible to prevent a reaction to the operator due to oscillation of the polishing machine generated during the polishing and to improve a discharging function for the polishing waste to the outside by allowing the polishing waste generated during the polishing to easily intrude in the concave grooves. Additionally, during the polishing, the air from the outside is flown through the concave grooves so as to increase the contacts with the outside air, which enables to improve the discharge efficiency of the friction heat generated in the polishing.

摘要： Molten resin is continuously extruded from an extrusion nozzle having a selected width, and at the same time, a plurality of parallel fiber filaments are introduced straightly toward the molten resin outlet in a direction along rotation of a die wheel and/or traversing one or more filaments by a predetermined width. The molten resin extruded from the extrusion nozzle and the filaments are introduced into a predetermined gap for molding a plate-like substrate sheet between the nozzle and the die wheel, which has a multiplicity of hook-forming cavities in its circumferential surface and is rotatable in one direction, and at the same time, the hook-forming cavities are filled with a part of the molten resin. The filaments are embedded in the substrate sheet of the extruded molten resin as the die wheel is driven to rotate in the direction of extrusion of the molten resin, and a plurality of hooks are continuously molded on a surface of the substrate sheet.

摘要： Molten resin is extruded in a predetermined width from an extrusion nozzle. The molten resin is forced to a die wheel, which is situated facing the extrusion nozzle with a predetermined gap therewith, has inside a cooling unit and is adapted to be rotated in one direction. On the surface of the die wheel, a flat-plate-like substrate member and engaging members are integrally molded of the molten resin. Simultaneously, as a continuous filament is supplied, loop members are successively formed. Then the loop members are pressed against the substrate member in upright posture and are successively fused therewith.

摘要： A molded surface fastener comprising a substrate sheet, and a multiplicity of engaging elements molded in rows on one surface of said substrate sheet. Each of the engaging elements has a pair of stems standing from the one surface of the substrate sheet, and a pair of hooks extending in opposite directions from distal ends of the stems and formed in a pair of parallel planes perpendicular to the general plane of the substrate sheet on opposite sides of the central line of the pair of stems. When companion loops are disengaged from the engaging element, the individual hooks are angularly moved about the central line of the pair of stems in a horizontal plane independently of each other and, at the same time, are expanded upwardly. As a result, the loops and the engaging element can be disengaged from one another smoothly without any damage.
