Abstract
A reserve feed stock is pieced with a production feed stock, particularly a roving of a ring spinning machine. The piecing operation can be accomplished by applying twist to predetermine portions of the reserve and production feed stocks and then releasing such applied twist upon separation of the reserve and production feed stocks at predeterminate locations thereof.
