ABSTRACT:
A bead former (14) has a gripping mechanism (90,92) for gripping a leading end (106) of a bead ribbon (12) at a position recessed in the surface (18) of the former (14) during the initial rotation of the former (14). The gripping mechanism (90,92) has a seat member (92) movable radially outward of the former (14) into a supporting position at the surface (18) of the former (14) after releasing the leading end (106) for supporting the leading end (106) during the latter rotation of the former (14). A pressure roller (20) is rotatably supported in a guide cage (54) mounted on a dual arm (22,48) having a dual actuation system (34,60) for moving the guide cage (54) and pressure roller (20) into position for guiding and compacting the convolutions of bead ribbon (12) wrapped around the former (14) and for providing a high pressure force to crimp the splice area (124 ) of the bead (16). A bead handling mechanism is provided to remove and accumulate the beads (16) in a spaced condition on belts (180) of unloading fingers (125) from the bead former (14).
