Abstract

A system of cores for producing by a molding operation plastic spool bodies, comprising a pair of mutually engaging male units, each of which is constituted by a body having a plurality of spaced apart male elements and protrusions, of which the male elements of a unit mutually engage the male elements of the associated unit, the movement of said male units towards each other being restrained in order to hold together the male units with the ends of the elements of opposing units in spaced relationship to form chambers in a resulting mold in which end wall portions of a spool body are formed, characterized in that aligned means centrally disposed to both spacer units and spaced with respect to said elements form in combination with elements of both units a chamber in which an inner tube of reel is formed integrally with at least part of said portions of end wall, forming the mold in which outward said elements, in whose other chamber an outer spool tube is integrally formed with part of said end wall portions.
