Claims.
This invention relates to improvements in selfthreading, thread-storage, thread-advancing devices.
In the manufacture of threads, yarns and the like it is often desirable to subject the traveling thread to a processing step. Devices on which traveling thread can be processed have been suggested before, such as spaced canted rollers or godets. While these devices enabled a large quantity of thread to be stored and subjected to the processing operation, they were open to the objection that they were not readily self-threading and often the thread became tangled around one of therollers or godets and was damaged I and hard to remove.
This invention has for its principal object to provide improvements in self-threading, threadstorage, thread-advancing devices.
A further object of the invention is to provide improvements in self-threading, thread-storage, thread-advancing devices on which the thread will not become tangled and from which it can be readily removed.
Other objects and advantages of the invention will be apparent from the following description and accompanying drawing.
In the drawing:
Figure 1 is an elevational view of a preferred form of device embodying applicants invention.
Figure 2 is an end view of the form of device 30 shown in Figure 1.
Figure 3 is a sectional view on line 3-3 of Figure 2 with parts broken away.
The embodiment of the invention shown in the drawing comprises the roller members I and 2 revolvably mounted on the shafts 3 and 4. The shafts are not parallel but are canted or mounted at an angle to each other. The continuous, flexible, foraminous belt-like member 5 of wire mesh, chain links or fabric passes over the rollers. The belt-like member is sufficiently flexible to conform to and travel with each roller with which 'it isin contact. Spaced apart, transversely extending bar members 6 are carried on the outside of the belt-likemember in a manner that permits the belt to flex. The bar members are shown as unitary members extending across the belt but may comprise a plurality of longitudinally spaced the roller with which they are in contact and maintain the belt-like member on the rollers. The belt-like member may be slightly longer than the path around the rollers so that while operat- 5 the side of the belt to which the thread is first directed larger than the ends of the rollers adjacent the side of the belt from which the thread is withdrawn. Where it is desired to prevent shrinkage or to stretch the thread, the taper 0 may extend in the opposite direction.
In the operation of the device at least one of the rollers is positively revolved in the direction shown by the arrow in Figure 2. The thread is directed to the belt member where it contacts the transversely extending bar members. Due to the flexibility of the belt, each part travels in the same path as the part of the roller with which it is in contact. The bar members move in a curved path concentric with the portion of the roller over which they pass. The thread is directed to the device under a slight amount of tension and while traveling with the belt-like member changes its path of travel from movement in a plane at -right angles to the axis of one roller to movement in a plane atright angles to the axis of the other roller and thereby traverses across the belt-like member. In order to limit the sliding of the thread along the bar members while traversing across the belt-like member, the belt-like member may be slightly longer than the path around the I rollers. Due to the slack in the belt-like member, one side of the belt-dike member paSSing'between the rollers will be maintained taut while the other side will curve inwardly as indicated by reference character A. The thread while changing its path of travel from one roller to the other will not be m contact with the bar'members in the slack portion of the belt-like member.
The term thread or strand as used through- 40 out the specification is intended to include yarns,
- threads, cords, filaments and the like.
While a preferred embodiment of the invention has been shown, it is to be understood that changes and variations .may be made without departing from the spirit of the invention as defined by the appended claims. What I claim is:
1. A thread-storage, thread-advancing device comprising a pair of canted rollers, an endless o belt member of flexible forami'nous material carried byand about the rollers and transversely extending thread contacting members mounted on the belt member.
2.

5. A strand-storage and advancing device for supporting and advancing a strand in a plurality of turns across the device comprising a plurality of canted rollers and an endless strand carrying belt member passing over the rollers in contact with only a portion of the periphery of each of the rollers, means for retaining the strand carrying belt member on the rollers in position to support and traverse said strand and preventing substantial displacement of the strand carrying belt member lengthwise of the device, said strand carrying belt member being of a width equal to at least the path of traverse of the strand across the device. V
6. A strand-storage and advancing device comprising a pair of canted rollers and an.. endless strandcarrying belt member passing .jover the rollers in contact with'only a portion of the periphery of each of the rollers, said strand carry ing belt member extending substantially the length of the rollers '7. A strand-storage and advancing device comprising a pair of canted rollers and an endless strand carrying belt member passing over the roilers in contact with only a portion of the periphery of each of the rollers, said strand carrying belt member being of a greater length than the path around the rollers and of a width substantially equal to the length of the rollers.
8. A strand-storage and advancing device comprising a pair of canted rollers, an endles belt member carried by and about the rollers in contact with only a portion of the periphery of each of the rollers, said belt member having a strandcarrying peripheral portion of substantial width for carrying a plurality of laterally displaced convolutions of the strand about the rollers withoutpermitting the strand to contact the rollers for any substantial distance, and means for preventing substantial displacementof the strand carrying belt member on the rollers in a direction longitudinally of the rollers.
9. A strand-storage and advancing device comprising a pair of canted rollers and an endless strand carrying belt member passing over the rollers in contact with only a portion of the periphery of each of the rollers, said belt member having "a strand-carrying peripheral portion of substantial width for carrying a. plurality of laterally displaced convolutions of the strand about the rollers without permitting the strand to contact the rollers for any substantial distance,
means on said strand carrying belt member adapted to engage the ends of the rollers to prevent substantial displacement of the strand carrying belt member on the rollers in a direction longitudinally of the rollers. 10. A thread-storage, thread-advancing device comprising a pair of canted rollers and an endless strand carrying belt member passing over the rollers in contact with only a portion of the periphery of each or the rollers, saidbelt memher having a strand-carrying peripheral p rtion of substantial width for carrying a plurality of laterally displaced convolutions of the strand about the rollers without permitting the strand to contact the rollers for any substantial distance, said strand carrying belt member having portions adapted to overlapthe ends of the rollers to prevent substantial displacement of the belt member on the rollers in a direction longitudinally of the,
rollers.
