Definitions
- retaining rings are of a larger diameter than the coaxi- [52] US. Cl ..28/1.6 a] roller, thereby overlapping the other stuffer roller [51] int. Cl. ..D2g 11/12 forming a yarn guide channel.
- the retaining rings also [58] Field of Search ..28/1 .6, 72.14 rotate with the roller.
- the present invention relates to stuffer crimping apparatus having a pair of rollers adjacent the inlet of a stuffing chamber wherein threads, fibrous or filamentary, are stuffed into a wad of threads already in the stuffing chamber. This stuffing action imparts a crimp to the threads, which may be heat set forming a permanent crimp in the threads. The threads are then withdrawn from the chamber by numerous conventional means, and wound onto pirns or used for other purposes.
- rollers mentioned The purpose of the rollers mentioned is to force threads being fed through the rollers into the stuffing chamber, thereby stuffing them onto threads already contained in the chamber.
- rollers have stationary guides on each side of the rollers at their mutual point of contact.
- the guides keep incoming threads between the rotating rollers, assuring that the threads will be forced into the stuffing chamber.
- the stationary plates are subjected to a great amount of wear as the threads go by.
- This wear in the plates causes slits to form between the plates and stuffing rollers, often leading to threads being caught in the slits and breaking.
- the broken threads cause interruptions in production and adversely affect the quality of the crimped threads.
- the present invention utilizes a pair of stuffing rollers in a conventional manner.
- a tow of threads is guided onto the stuffing rollers by two discs or retaining rings concentric with one of the stuffing rollers.
- the discs being of a larger diameter than the concentric roller, provide an overlap of the cooperating stuffing roller near the point of contact of the rollers. This overlap may be from to 40 percent, but about 30 percent overlap is preferable.
- the discs are retained in position adjacent the stuffing rollers by means of hubs secured to the concentric roller shaft.
- the hubs may be secured by set screws, or any conventional method.
- Axial pressure members such as helical springs, may also be used between the hubs and retaining discs. By this method pressure can be brought to bear on the retaining discs, forcing them against the stuffing roller.
- the retaining discs rotate at the same speed as the stuffing rollers, greatly decreasing the wear rate of the discs, thus virtually eliminating the slits found in stationary guide members.
- FIG. 1 is a cross-sectional view along Line I-I in FIG. 2;
- FIG. 2 is a part sectional view along Lines II-II shown in FIG. 1.
- FIGS. 1 and 2 show a stuffer box crimper with stufi'er rollers l and 2 under a given load towards each other and rotatable in the direction shown by arrows 3 and 4 5$$$ES lilili 'vll ifil aifil" il iiilfi are supported in the usual manner on a crimping frame. Threads (not shown) are forced in the direction of arrow 7 through the stuffing rollers into the neck of stuffing chamber 8 formed by plates 9 and 10. (The sides of the stuffing chamber are not shown.) The stuffing chamber 8 has a hinged door 11 loaded with weight 12 for applying the desired counter pressure to the yarn wad in stuffing chamber 8 during operation.
- retaining discs 13 and 14 are slidably mounted on shaft 5. These discs are approximately 30 percent larger in diameter than the stuffing rollers l and 2 so that at and near the point of contact 15 of the two rollers, the end faces of the rollers are covered by the overlapping discs. Because of this larger diameter, the retaining discs form past the point of contact 15 part of the walls of the gradually widening upper portion of stuffing chamber 8. Thus, the discs at indicated point 16 are moving in substantially the same direction as the crimped wad of yarn, as the retaining discs rotate with the stuffing rollers.
- the discs are mounted on shaft 5 by means of hubs l8 and 19 clamped tightly on shaft 5 by conventional means (not shown).
- the retaining discs 13 and 14 are axially pressed against the end faces of stuffing rollers l and 2 by circumferentially arranged helical springs 20 provided in hubs 18 and 19.
- the tension in the springs 20 is adjusted by adjustment screws 21.
- Set screws 22 lock the adjustment screws in place.
- retaining disc 13 may be positioned on shaft 5 while disc 14 may be positioned on shaft 6.
- Apparatus for stuffer box crimping synthetic threads comprising:
- a stuffing chamber for receiving the synthetic threads
- forcing means comprise hubs secured opposite each disc along the axis of the discs, and one or more helical springs between said hubs and discs forcing said discs into the coaxial roller.
