Method and apparatus for programmed shaft synchronization

摘要

The invention relates to an apparatus and method for producing an elastomeric extrudate having a constant cross section area. The extrudate is shaped in to a ribbon through a roller die and applied to a tire surface mounted on a rotating spindle. Digital electronic circuitry is employed to provide precise shaft synchronization at a pre-selected rotational velocity ratio between the rotating shafts. The synchronization assures repeatable velocity synchronization between the source of elastomeric material and a take-up device at the axis of rotation of the two components. The elastomeric material is extruded in a manner permitting control over the wrap operation and the amount of elastomeric material employed for a given cycle.
