Description
J. R. DUNHAM FRICTION WINDING CORE Filed sept. 18, 1954" ATTORNEY CII Patented Mar. 24, 1936 PATENT OFFRE FRICTION WINDING CORE John Ryer Dunham, Highland Park, N. J., as-
signor to John Waldron Corporation, New Brunswick, N. J., a corporation of New Jersey Application September 18, 1934,' Serial No. 744,584
3 Claims.
This invention relates to friction Winding cores.
In many industries where paper, cloth or other material are wound on paper, wood or metal cores, it is generally customary to wind a plurality of rolls or bundles on one shaft or spindle. Upon the completion of the winding operation the material and its core are removed. This is sometimes cumbersome and dicult to accomplish. In addition, the friction or tension is usually on one end of the winding shaft. Also the difficulties increase to a certain extent in connection with the number of strips of material being wound.
One of the objects of this invention is to provide friction winding cores having individual tension in connection with each winding core.
Another object of the invention is to provide a friction winding core of simple construction permitting easy spacing of the cores on the shaft and ready removal of the cores bearing the material.
A further object of the invention is to provide quick threading or attachment of material to the core.
Referring to the drawing:
Figure l is a View in front elevation partly in section along the line I, I, of Figure 2.
Figure 2 is a view in cross section of Figure 1 along the line 2, 2, looking in the direction of the arrows.
In carrying out my invention, I provide a steel sleeve I which is journaled on the winding shaft or spindle of the winding machine. Encircling steel sleeve I is a collar 2. Also encircling steel sleeve I is the main body 3 of the winding core. Between body 3 and collar 2 is a circular felt friction ring 4. On the opposite end is a threaded portion 5 upon which is screwed a nut 6. Spanner holes I are formed in the face of nut 6. Between nut 6 and main body portion 3 is a steel washer 8 and between steel washer 8 and main body portion 3 is another felt friction ring 4'. An encircling coil adjustment spring 9 is interposed between washer and the sloping rear face I of nut 6. Body portion 3 has two chambers II formed exteriorly to hold serrated edge friction wheels I2 which are supported by shafts I3 journaled in the main body portion 3. Chamber I I is slightly larger in diameter than the serrated wheels I2 to permit a limited side sliding motion of the serrated wheel I2. Threaded exteriorly to body portion 3 are flanges I4, I4. Either flange may be independently removed. Between flanges I 4, I4', and encircling body portion 3 is the winding core I5. The internal diameter of the winding core I5 is sucient when one of the flanges is removed to permit ready insertion over the serrated wheels I2, the wheels rotating to permit insertion. After the core I5 is placed on body portion 3 and the flange I4 is again put in position, the serrated wheels I2 through their serrated surface grip the core to provide rotation for the winding of the material. The width of chamber II permits the serrated wheel I2 to slide endwise on shaft I3 and thereby increases the driving power of the wheels because as they slide along shaft I 3 such motion increases the diameter thereby increasing the grip o-f the serrated surfaces against the inside of the paper core I5. It being understood that the paper core I5 is thereby caused also to be frictionally pressed against the external surface of body portion 3, particularly opposite to wheels I2.
Where narrow strips of material areI wound it is difficult to secure the strips to the paper core. I therefore propose to provide a gummed flap I6 of considerable length which is attached at one end to the material and at the other end is wound on the external surface of paper core I5 to thread the material between flanges I4, I4', in order to start the wrapping of the bundle. The gummed flap I6 need only be allowed to contact with the rotating core without tension and the surface of the core will then pick it up and after one or tworotations the gumined flap I6 becomes tightly secured enabling the completion of the winding of the material. Body portion 3 is frictionally driven by steel sleeve I. This is accomplished by drawing up on nut 6 which compresses coil adjustment spring 9 against the steel washer 8 which in turn bears against felt ring 4', while at the same time collar 2 bears against friction ring 4 to clamp the body portion between nut 6 and collar 2. The tension and therefore the friction, can be adjusted by such construction and nut 6 is not easily accidentally displaced.
It will thus be seen that I have invented a frictional Winding core device which permits of easy insertion of the core on the winding shaft and the same easy withdrawal upon the completion of the winding of the material and at the same time provides a friction drive for the winding core to permit the winding up of the material which friction drive is of a positive nature so that no slippage will occur and the core may be driven in either direction of rotation.
I have also provided means for threading the material to be wound on the winding core.
Various modifications may be made and still fall within the scope of my invention. For instance, the side flanges I4, I4', may have one or both omitted particularly Where wide webs are being Wound.
What I claim is:
1. In a device for Winding paper, a sleeve, a body portion encircling said sleeve, means for frictionally securing said body portion to said sleeve, means rotatable to permit the sliding onto said body portion of a core and to drive said core with said body portion by frictionally gripping said core.
2. In a device for Winding materials into rolls, a sleeve, a body portion surrounding said sleeve and frictionally driven by said sleeve, a chamber in said body portion, a serrated roll in said chamber and projecting beyond the surface of said body portion, a core insertable around said body portion roll, means for increasing the driving power on said core, and flanges carried by said body portion extending beyond said core to prevent telescoping of the material being wound.
3. In a device for Winding materials into rolls, a sleeve, a body portion surrounding said sleeve and frictionally driven by said sleeve, a chamber in said body portion, a serrated roll in said chamber and projecting beyond the surface of said body portion, a core insertable around said body portion roll, means for increasing the driving power on said core, and flanges carried by said body portion extending beyond said core to prevent telescoping of the material being Wound, and means for securing and threading the material to the core.
