ABSTRACT:
Spin cycle apparatus employed in a glass article forming machine to drive article carrying chucks in rotation as the chucks are conveyed through burner sections of the machine. The spin cycle apparatus includes a spin cycle chain mounted on the machine frame to extend along a portion of the path followed by sprockets mounted on the individual chucks. As the chuck is carried along its conveying path, the sprocket engages the chain to cause the chuck to rotate as it is advanced. That section of the chain which is initially contacted by chuck sprockets is aligned at an angle convergent to the sprocket path and is resiliently maintained at a somewhat looser tension than is the main sprocket driving portion of the chain. This distributes the length of the chain over which the randomly oriented sprocket teeth initially engage the chain and cushions the impact between the sprocket teeth and the chain.
Two embodiments are disclosed. In one embodiment, the chain is stationary and the rate of spinning rotation of the chuck is dependent upon the conveyor line speed. In the other embodiment, an endless chain having one run located to operatively engage the chuck sprockets is driven by a reversible variable speed motor so that the rate of chuck rotation can be adjusted independently of conveying line speed by appropriate selection of the direction and speed at which the endless spin cycle chain is driven.
