6-Station Bead Winding Machine (PCR)
Winds six PCR bead cores per cycle straight from bare wire — let-off, preheating, rubber coating, cooling, accumulation and traverse winding in one automatic line at 18 beads per minute.
Overview
The Pinshun bead winding machine turns spooled bead wire into finished bead cores in a single automatic cycle, winding six beads at a time. Wire runs from six let-off stations through a preheater and a rubber coating unit, then through cooling and haul-off and a low-tension accumulator before it reaches the winding head.
The winding head lays the wire in a controlled traverse pattern, building hexagonal or rectangular bead sections of 3 to 6 layers with up to 15 wires per layer, across a 13"–20" bead diameter range. Process temperature is controlled to ±1 °C, and finished beads are transferred to a three-station storage unit at the outfeed.
Rated output is 18 beads per minute on a 15" bead of 24 turns. Bead cores from this machine feed the apex applying machine downstream, and from there the bead setting station of the building machine.
