Abstract: To permit pull-off of elastomeric yarn from a spool, without subjecting the yarn to tension, the spool (6) with the yarn (17) wound thereon is placed on a pair of horizontally extending support-and-drive rollers (3) which are driven at pull-off speed by a belt drive (7, 8, 10) from the textile machine via a right-angled drive (FIG. 3) from a drive pulley (11). The drive is reversible. The yarn is fed by frictional engagement of the yarn portion being pulled off the spool with a portion of the circumference of the driven support-and-drive rollers (3) and, if the weight of the spool is not sufficient to provide for suitable frictional engagement, the surfaces of the rollers can have knurling or a rubber coating thereon; they may be spring-loaded or weighted. Additional drive can be obtained by looping an endless belt (24) about the rollers, and seating the spool (6) in a concave depression formed by the belt as the spool is positioned between the support-and-drive rollers.

Abstract: The trailing end of a running tow of filamentary filter material in a filter rod making machine is spliced to the leader of a fresh tow, and the splice is held at a preselected location ahead of the first tow treating station in the machine. An optoelectric or pressure-responsive detector generates a signal when the splice advances beyond such location on expiry of the running tow, i.e., when the second tow begins to advance through the machine. The signal is used to reduce the speed of the prime mover of the machine during travel of the splice therethrough, to increase the width of passages which are defined for the tow by the banding, spreading, stretching, plasticizer-applying and/or other units for the tow so that the splice can readily advance therethrough, and/or to effect automatic segregation of those filter rod sections which contain portions of the splice.

Abstract: A combination yarn processing machine and overhead creel assembly comprising a machine mounted overhead creel assembly including a bobbin carriage which pivots about an axis mounted on a framework above the yarn processing machine.

A spring loaded counterbalancing system holds the bobbin carriage in the up position and in the down position and aids in minimizing the effort expended by operators servicing the machine while moving the bobbin carriage between the up and down position.

Abstract: 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.

Abstract: With the creel for a spinning machine according to the invention at least two rows of rotatably suspended roving bobbins, which extend essentially in parallelism with respect to one another, are adjacently lined-up. Normally in ring spinning machines there are employed for such creels roving deflecting rods which extend horizontally in the longitudinal direction of the ring spinning machine. The rovings extending from the roving bobbins to the drafting arrangements are guided around the deflecting rods for the purpose of guiding the rovings. If the deflecting rod is located behind the bobbins, then insertion of the rovings about the rods is extremely cumbersome, and additionally, there exists the danger of damaging the rovings. If the deflecting rod is located further towards the front, then exchange of the bobbins becomes tedious. These drawbacks are eliminated with the invention in that a row of substantially rod-shaped holders is arranged behind the front row of roving bobbins.
