Abstract

1,264,361. Tyre-bead turn-up and stitching device. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT PO OBORUDOVANIJU DLYA SHINNOI PROMYSHLENNOSTI. 21 Feb., 1969, No. 896/69. Heading B7C. A device for turning-over and stitching plies around a bead core in a tyre-building drum 14 comprises a stitching roller 9 rotatable on an arm 8 pivoted at 7 to a link 6 and connected to the piston-rod of a piston and cylinder device 10 which moves roller 9 around the bead core 13 and applies stitching pressure thereto, the speed of movement being controlled by a dashpot 12, preferably an hydraulic dashpot. All the parts are pivoted to a plate 1 which can be fixed to the tyre-building machine. As the roller passes towards the inside of the bead region, it lifts the region away from the drum end, enabling the roller to apply stitching pressure on the axially inner surface of the region.
