Coil forming apparatus with axially adjustable mandrels

摘要

A coil forming apparatus has a pair of mutually perpendicular elongated mandrels mounted on a hub. Rotation of the hub about an axis perpendicular to the mandrel axes results in the mandrels being moved between a collecting station at which they protrude vertically from the hub to receive product rings from an overlying delivery device, and a discharge station at one side of the hub at which they protrude horizontally to accommodate axial removal of the coils. The mandrels are axially adjustable relative to the hub, and each mandrel has oppositely disposed ends adapted to receive rings from the delivery device. A retracting device is employed to withdraw each mandrel across the rotational axis of the hub from the discharge station to an intermediate station on the opposite side of the hub.
