Abstract
A plurality of fasteners are joined together as they are laminated in the direction of the thickness thereof, to form a fastener assembly. Each of the fasteners consists of a substantially H-shaped body composed of a head section, a bar section opposed to the head section, and a filament section by which the head section and bar section are joined together. Each of the fasteners is obtained by punching a film or a sheet of a synthetic resin. After a plurality of such fasteners as described above have been laminated in the direction of the thickness thereof, the bar sections are fused together in such a manner that the fasteners can be separated one by one.
Claims8
A method of manufacturing a continuous assembly of fasteners, each said fastener including a head section and a bar section joined together by a filament section comprising the steps of successively punching individual fasteners out of a sheet of synthetic resin material, successively delivering said fasteners in a downward direction so that said fasteners are laminated in a continuous stack of fasteners, heating the bar sections of said fasteners so that said bar sections are fused together to form a continuous assembly of joined fasteners, successively stretching the filament sections of said fasteners, and delivering said stacked, joined and stretched fasteners in a continuous assembly.
An apparatus for manufacturing a continuous assembly of fasteners, each said fastener including a head section and a bar section joined together by a filament section comprising punching means for successively punching individual fasteners out of a sheet of synthetic resin, laminating means positioned below said punching means for successively receiving said punched fasteners and for stacking said fasteners one on top of another, joining means positioned below said laminating means for joining the bar sections of said stacked fasteners together and stretching means positioned below said joining means for stretching said filaments of said joined, stacked fasteners, said joined, stacked and stretched fasteners being delivered from said stretching means in an endless, continuous manner.
