Abstract

The machine is fitted with a device to fix the filler piece sides near the two ends of the piece, and a device for the butt splicing of the two ends. The machine consists of two discs which contact each other on the periphery. The lower disc holds the bead core in an annular groove. An annular slot in the top disc locates the upper part of the triangular filler piece. A pair of pressure elements fix the opposing sides of the filler piece near each end. A device to complete their butt joint includes pairs of arms. A getting and centring device ensures that the ends are joined only if the length of the elastomer protruding from the arms to the ends is >=0.5 mm. This saves labour for the mutual arrangement of bead core and filler piece and ensures a uniformly good joint.
