Abstract

PURPOSE:To continuously produce a gut for a racket composed of a twisted thread bundle shrouded by mesh, by extruding filiformed molten resin from the center of a mouthpiece coupled to an extruder, while extruding reticulated molten resin from the periphery of the mouthpiece. CONSTITUTION:An inside mouthpiece 14 an an outside mouthpiece 13 provided with grooves 16, 17 for extrusion of molten resin are rotated along opposite direction together, and molten resin is extruded from the grooves 16, 17, so as to form a net 31. At the same time, a plurality of molten resin filaments are extruded from through holes 55 of a central mouthpiece 51, to form a filiform bundle 56. Thus, a gut 57 for a racket comprising the filiform bundle 56 shrouded in the net 31 is produced. The filiform bundle 56 may be a single thread or a twisted thread bundle 58 having a desired twisting pitch formed by proper rotation of the central mouthpiece 51. Consequently, the gut which has a good dimensional stability, suitable for application of a driving or spinning action can be obtained.
