Реферат: The bead core rings for pneumatic tyres consist of stranded electroplated wires which must be protected at the start and end against stray wire ends by a sleeve of closely woven tissue. The wrapping operation is mechanised by a revolving form disc with recesses at the periphery in which the ring is covered on three sides by the tissue. The outstanding ends are laid flat by two facing sliders and folded flat over each other. A form disc has several square recesses on the periphery. Each recess is covered by a strip of closely woven tissue which is held flat by the suction bores. When a bead core ring is pushed in the recess, its joint is wrapped on three sides in the tissue. A slider first folds the left stand-out flat, and the other slider then folds the right stand-out over it. This completes the wrapping operation. This saves the manual labour and ensures a uniform quality.
