'1 Claims. Cl. 28-.71.6)

My invention relates to a new and improved reeling device, and to a new and improved method of reeling yarns, filaments, threads, and flexible bodies of all shapes and of all materials.

The invention is particularly useful in hanstrokes, each forward feeding stroke operating upon a respective circumferential portion of the helix. Consecutive feeding strokes operate upon different circumferential portions of the helix.

invention are stated in the annexed description and diagrammatic drawing, which illustrate two preferred embodiments thereof. It is to be understood that the above general statement of Numerous additional important objects of'the 55 the invention does not limit its scope.

Each edge 6 may be in a series of intermittent forward feeding sharp or blunt and it may be of any shape,

such as a rounded shape, etc.

Each sleeve-carrier 5 has a rear flange 9, which is held in contact with the front operative face of cam l0. Each sleeve-carrier 5 is biased so that its flange 9. slidably contacts with the front operative face of cam It, by means of a biasin compression spring I2. For this purpose, 2. iongitudinal rod a is fixed to the front end-wall 5c of each sleeve-carrier 5. Each rod 5a. is located in a respective tube 4. Each spring I2 has its front end abutting a respective plug Ila, which is fixed to the respective tube Each rod be has a head 51) fixed thereto. Each head 5b is located rearwardly of the respective plug lid. The rear end of each compression spring 82 abuts the respective head 5b.

A second series of bars orcarriers 3 are fixed to the reel 2. Each said bar or carrier 3 has a tapered projection, which has a thread-supporting surface or edge I. Said edge 1 may be sharp or blunt, rounded, etc. The edges I are of sufficient length to support all the turns of the helix of the thread 14.

Fig. 2 shows that the wall of each sleevecarrier 5 has a slot or groove [3a which is of general triangular shape between its front and rear corners. This groove I311 has a. leg L, whose shape is substantially that of a part of a helix. This groove l3a. has another leg La, which has two branches, each branch having the shape of a part of a helix. The branches of leg La are inclined to each other. The rear branch is more sharply inclined than the front branch, relative to the longitudinal axis of sleeve 5.

Each tube 4 has a guide pin G, which projects into the respective groove 13a of the respective sleeve-carrier.5. Hence, when a sleeve-carrier 5 is in its extreme rearward position, the respective pin G is at the front corner of the respective groove Ilia.

During each longitudinal forward movement of a sleeve-carrier 5, the respective pin G which is fixed to the respective tube l, is located in the leg L, so that the turning effect on each sleevecarrier 5 during said forward movement, is the same as though pin G were moved rearwardly in leg L. Hence, during each longitudinal forward stroke of each sleeve-carrier 5, said sleeve-car rier is uniformly turned clockwise, if the observer is standing in front of the reel 2, namely, at the right of reel 2 in Fig. 1.

During each rearward stroke of a sleeve-carrier 5, said sleeve-carrier 5 is first turned sharply counterclockwise, so that the respective edge 6 will promptly lose contact with the respective part of the helix of the thread M. As an example, during each forward stroke of a sleeve-carrier 5, its edge 6 can engag the helix of the thread It and raise the entire respective part of the helix radially outwardly from the adjacent edges I, while the reel 2 is turned through an angle of thirty degrees to forty-five degrees, and even thirty degrees to ninety degrees. The operative thread-raising positions of edges 6 are shown in positions F, E, C, A. In said positions, the respective bulged part of the helix is supported only on the respective four edges 6. In position A, the sleeve-carrier 5 is at the end of its forward stroke, In position B, the sleevecarrier 5 is at the end of its rearward stroke. During its rearward stroke, each edge 5 loses contact with the helix, while the reel is turned through a small angle of about fifteen degrees, as shown in position D.

Each edge I is of sumcient length to contact with all the turns of the helix of the thread If! which is wound on the reel.

Assume that only the edges 6 support the helix of the thread H3, raised radially outwardly from edges 1, in an arc of forty-five degrees anterior the position A. The helix .of the thread it will be supported on the edges 6, in the remaining part of the circumference of the helix. The part of the circumference of the helix, in which the turns of the helix of thread it are supported wholly on edges 6, is called the bulged part or zone or said helix. As later described, said bulged part is continuously shifted clockwise around the circumference of the reel, if the observer is in front of the reel.

Hence the bulged part of the helix is sometimes at its top, sometimes at its bottom, etc.

It is preferred simultaneously to rotate cam l0 and reel 2 in the same direction, but at different angular velocities. As an example, the reel 2 can turn sixty revolutions per minute, and the cam Ill can turn in the same clockwise dlrec= tion, seventy-two revolutions per minute. The length of each forward feeding movement of the respective bulged part of the helix of thread it, may be 0.09 inch. The thread It is always wound or supported continuously upon some of the edges 1 and on some of the edges 5, and it is unwound continuously at the front end of the reel.

In the embodiment of Fig. 4, the only difference is that each sleeve-carrier 5 is located circumferentially between a pair of bars 3.

In the construction shown, the front ends of bars 3 and of the supporting edges 6 of sleevecarriers 5, are free from any obstruction. Hence the front turn or turns of the helix can be fed intermittently over the free front end of the reel. The thread which is thus unwound from th front end of the helix can fall into a suitable receptacle, or it can be wound upon a reeling device. The thread which depends from the helix at its front end, can therefor be free from tension,

or it can be subjected to continuous or intermittent tension.

In the embodiments described herein, the number of edges 6 is equal to the number of edges 5. The invention is not limited to this relation.

In order further to illustrate the invention, if

the helix is made of artificial silk filament l6 which is supplied by a spinning nozzle, th thickness of said filament It is about 300 denier or more. There will be seventy-six turns of such filament M in the helix. The longitudinal distance between adjacent turns will b 0.09 inch. The longitudinal stroke of sleeve-carriers 5, from maximum rearward position to maximum forward position will be .09 inch. The normal diameter of the helix, as determined by edges i, will be six inches. The maximum radial enlargement of the helix will be 0.125 inch, in the bulged part of the helix.

Whenever reference is made to a thread in a claim, this designation includes filaments and flexible members of allshapes and of all materials.

By increasing the number of bars 3, the trans= verse contour of the thread of the helix can be mad to approximate a circle.

The invention is not limited to the use of bars or carriers 3, which are fixed to reel 1.

The shape of the helix is invariable, even though the-position of its bulged zone or part is shifted circumferentially around the reel.

The filament or thread which is led off the helix, is preferably subjected to continuous and uniform tension. Hence, the filament or thread can be subjected to uniform tension at all times.

I have described preferred embodiments of our invention, but numerous changes and omissions and additions can be made without departing from its scope.

For convenience, the radial direction may be designated as the transverse direction, and the circumferential spacing of

members

3 and 5 may be designated as lateral spacing.

Since the cam and the reel are rotated at different angular speeds, the high point of the cam, which controls the extreme forward position of each movable sleeve-carrier 5, is shifted circumferentially relative to the reel.

Hence, the automatic means which operate the reel and the cam, progressively shift the location of the movable sleeve-carrier 5 which is in its extreme forward longitudinal position.

Hence, the location of the portion of the helix which is fed longitudinally forwardly, is progressively circumferentially shifted. The angle of the circumferential shift between successive movable sleeve-carriers 5, is less than the angle of the portion of the helix which is forwardly longitudinally fed.

The entire helix is at all times located on supporting means which move in unison with the reel, around the axis of rotation of the reel. There is little or no circumferential shift or rubbing movement between the helix and its supporting means.

When I refer to a helix, I include a winding whose respective turns may be of different shape and of different dimensions.
