In strand user devices such as a yarn storage feeder system of the type disclosed in U.S. Pat. No. 3,776,480 and having a yarn storage unit upon which a quantity of yarn is maintained from a yarn supply for intermittent withdrawal and delivery to yarn consuming means, a significant improvement in efficiency of the strand user device is achieved by incorporating strand guide means which are operable to control the movement of the strand, especially strand in the form of tape, from its supply source and into the user device while precluding fibrillation or splitting of the tape. Particularly in the handling of plastic tape fibrillation or splitting of the tape can occur as the tape is drawn from its supply source and guided in an angular path through a stationary member directing it to the inlet end of the storage feeder. Such fibrillation or splitting is avoided in practice with the present invention which incorporates roller means for guiding the tape to the feeder while maintaining tension into the tape at a generally uniform level both upstream and downstream of the roller means. |
