ABSTRACT:
The present invention consists of a spindle arm for use in batch-type rotational plastic molding machines. The invention herein includes two cylindrical arms, one end of each arm attached to a gear housing and extending therefrom in a common axis. The gear housing contains gears for providing connection between and transmission of rotation from, a driving shaft, extending from the gear housing, to a driven shaft, extending through the gear housing in an axis perpendicular to the driving shaft. The end of the driving shaft extending from the gear housing is attached to a drive sprocket, the sprocket providing for releasable connection to a drive motor of the molding machine. The driving shaft is contained within one of the cylindrical arms and is rotatably supported therein. The other cylindrical arm is attached, on the end extending from the gear housing, to a second drive sprocket for providing releasable connection to a further drive motor of the molding machine.
