<p>The invention relates to an apparatus and a method of forming an annular apex filler for tire beads. Said apparatus comprises a cylindrical former (2) for supporting a cut length of an apex filler strip (91) of elastomeric material, wherein said cylindrical former (2) comprises a hollow rotary shaft (21) and a plurality of rigid, circumferentially spaced apart fingers (22). The fingers (22) are movably connected to support members (24) for flipping the apex filler when wound on the cylindrical former. The support members (24) are movable connected to substantially radially extending guiding members (25). The guiding members (25) are connected to a hollow rotary shaft (21). The fingers (22) are connected via linkages (27) to a driving member (281) which is connected to a push/pull shaft (28) which extends at least partially through the hollow rotary shaft (21). Said apparatus further comprises a setting unit comprising a setting plate (26), said unit being arranged for moving the support members (24) radially inwardly or outwardly, and a feed assembly for feeding said apex filler (91) to said cylindrical former (2).</p> |
