ABSTRACT:
When feed stock is pulled from storage and a portion cut off for use by an operator, such as a builder of tires, the remaining portion of feed stock not used by the operator for the tire he is building ("unused stock"), interferes with the tire building process. Therefore, the tire builder must take the time, and make the additional effort to move the unused stock out of his way, usually by pulling the end of the unused stock into a retaining clip on the tray of the `servicer` which presents appropriate stocks to the tire builder. To avoid the inconvenience to the tire builder who must move the unused stock out of his way, and to save the time required for him to do so, a spring actuated cam roller is used to release the feed stock to the tire building machine when the operator pulls on the stock. After the operator cuts off a predetermined portion, a controlled reverse rotation of the cam is automatically spring actuated so as to retract the end of the unused stock and keep it out of the operator's way. The distance the end of unused stock is retracted is adjustable.
