10 Claims. (Cl. 57-74) This invention relates to spinning frames and twisting frames, and more particularly to cap spinning frames and cap twisting frames.
An object of the invention is to provide a cap spinning frame or cap twisting frame, by means of which the formation of large balloons at certain speeds is avoided, so that breakage of thread by the collision of adjacent balloons and by increased air friction is eliminated.
A further object of the invention is to provide a cap spinning frame or cap twisting frame by means of which a predetermined tension in the thread may be accurately maintained.
Another object of the invention is to provide a cap spinning frame or cap twisting frame by means of which undesired loose windings on the bobbin are avoided.
Still another object of the invention is to provide a cap spinning frame or cap twisting frame by means of which the occurrences of broken ends caused by the differences of twist imparted to different portions of the thread are eliminated and, consequently, differences in the strength of the thread and its resistance to tension and breaking forces are avoided. H
A further object of the invention is to improve the braking of the cap when the cap spinning frame or cap twisting frame is stopped.
Still another object of the invention is to improve on the art of cap spinning frames and cap twisting frames as now customarily made.
Other objects and structural details of the invention will be apparent from the following description when read in conjunction with the accompanying drawing forming part of this specification, wherein:
The figure is an elevational view, partly in section of a cap and associated portions of a cap spinning frame according to the invention.
It is understood that the arrangement according to the invention may be applied either to cap spinning frames or to cap twisting frames and that the term twist imparting frame used hereinafter in the specification and/ or claims shall have reference either to a cap spinning frame or to a cap twisting frame.
Referring now to the drawing, 30 generally indicates an electric motor having a stationary casing 3 closed by a cover 2 attached thereto. A vertical hollow axle 1 fixedly inserted into a bore of the cover 2 depends from the latter.
32 generally indicates a cap. Said cap 32 comprises a neck portion 17 having a flange 6, a cylindrical main portion 5 and a ring 9, said main portion 5 being in rigid connection with the flange 6 at one of its ends and with the ring 9 at its other end. The neck 17 of the cap 32 is rotatably mounted on the axle 1 by means of a plurality of bearings, for example by a pair of ball bearings 4 as shown in the drawing. Moreover, the neck 17 of the cap 32 is rigid with the rotor 34 of the electromotor 30 for rotation by the latter.
A thread guide 7, substantially in the shape of an inverted frusto-cone having an inverted Y-shaped perforation 19 therethrough, being arranged inside said cap 32 is rigidly connected with the flange portion 6 of said neck 17. 7
Thread 8 supplied to the device by the feed rollers 16 may pass through the bore of said hollow axle 1 and through the perforation 19 of the thread guide 7 into the interior 11 of the cap 32. During the operation of the device, the thread guide 7 rotating with the cap 32 imparts an initial twist to the thread 8.
The ring 9 secured to the cylindrical wall 5 of the cap 32 guides a traveller 10 movably mounted thereon. The traveller It) is slidably engaged with shoulders 20 of said ring 9.
The upper end of a rotatable vertical spindle 21 separately driven by another electric motor 13 projects into the interior 11 of the cap 32. A bobbin tube 14 capable of receiving a wound body 15 is drivingly engaged with a bobbin carrier 12 mounted on the spindle 21 for rotation with the latter.
The operation of the device is as follows:
Thread 8 is supplied by the rollers 16 through the hollow axle 1 and the thread guide 7 to the traveller 10 in the interior 11 of the cap 32. The thread 8 following the rotation of the traveller 10 is conveyed along the bobbin tube 14 so as to form the wound body 15.
When the twist imparting frame is started, the cap 32 is rotated by the electric motor 30 and the spindle 21 is rotated by the electric motor 13. During the operation of the device the thread 8, together with the traveller 10 guided by the ring 9, rotates around the spindle 21 at a number of rotations per minute equal to the number of rotations per minute of the spindle 21 less the number of windings made per minute on the body 15. The cap 32 is rotated at a lower speed than the spindle 21 and the traveller 10 rotates relative to the rotation of the spindle 21. If, for example, the spindle 21 rotates at 10,000 rotations per minute, the circumference of the body 15 equals millimeters, and the feed rollers 16 supply 10 meters (i. e. 10,000 millimeters) of thread per minute for the formation of windings of the body 15, then 100 windings per minute are obtained. Thus, the number of rotations per minute of the traveller 10 amounts to the number of rotations per minute of the spindle 21 less the number of windings per minute, i. e. 10,000100=9900 R. P. M.
As mentioned above, the cap 32 rotates at a lower speed than the spindle 21. Therefore, the friction between the ring 9 and the traveller 10 is just sufficient to obtain the desired tension in the thread during the winding thereof. 7
The guiding of the thread 8 by the thread guide 7 subjects immediately the thread 8 to an initial twist up to the feed rollers 16 which are arranged at a comparatively small distance from the cap 32.
In order to obtain the optimum relation between the speeds of the spindle 21 and the cap 32, the electric motors 13 and 30, respectively, are equipped with pole changing windings and the relationship of the electrical values of said two motors is changed as needed. For example the motor 30 driving the cap 32 may have a higher rate of slippage in percentage in relation to the motor13 driving the spindle 21.
Furthermore, for an advantageous braking of the cap 32 when the twist imparting frame is stopped, preferably controllable direct current or reverse current or eddy current is supplied to the motor 30.
I have described a preferred embodiment of my invention, but it is understood that this disclosure is for the purpose of illustration, and that various omissions and changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for as the arrangements shown and described may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
For example the cap 32 and/ or the spindle 21 may be driven by means other than the electric motors shown in the drawing and described above.

1. In a twist imparting frame, the combination of: a substantially vertical rotatable spindle capable of operative engagement with a bobbin, first driving means operatively connected with said spindle for driving same, a substantially vertical rotatable cap, second driving means operatively connected with said cap for rotating same independently of the rotation of said spindle, said spindleextending into the interior of said cap, a traveller inside said cap, said traveller being movably mounted on said cap atthe lower end thereof, a thread guide inside said cap above said spindle, said thread guide being rigid with saidcap so as to rotate with the latter, and passage means on said cap, said passage means registering with said thread guide for leading thread from the outside to said thread guide, the passage means and traveller being located within the interior of said cap to contain the thread fed therebetween interiorly of said cap.
