Title: Elongate material spreading and tacking apparatus and method

Abstract: PCT No. PCT/US79/00449 Sec. 371 Date Jun. 26, 1979 Sec. 102(e) Date Jun. 26, 1979 PCT Filed Jun. 26, 1979 An apparatus and method is provided for heat tacking of elongate material or cables (32) to a tire carcass (15) on both peripheral sides of a core opening (20), spreading the elongate material or cables (32) lying over the core opening (20) so as to position the elongate material or cables (32) on either circumferential side of the core opening (20), and heat tacking the spread elongate material or cables (32) to the tire carcass (15). The apparatus includes a frame (40) having locating pads (72,102) for positioning the heat-tacking and elongate material or cable-spreading subassembly (110) with respect to the core opening (20). The tacking members (120,125,120) are preheated to a tacking temperature so that when the frame (40) is clamped onto the carcass (15), and the elongate material or cables (32) are spread, the spread elongate material or cables (32) are tacked to the carcass. A core plug (25) may act as the elongate material or cable-spreading member and may be optionally removed when the frame (40) is removed from the carcass (15).
