In Canada December 30, 1944 8 Claims. v '(Cl. 242 -68) In the art of paper making, winding reels are employed for the purpose of winding the paper web thereon as it comes from the calender rolls of the paper making machine without interfering with the continuous run of paper from the machine. It is common practice therefore in winding operations to dispose a winding reel on each side of the winding drum and when a given quantity of paper is wound upon one reel the opposite reel is started, brought up to winding speed and the paper web or sheet then switched from the full to the empty reel without interfering with the continuous paper run.

The starting or rotating operation of the empty reel on the machine side, commonly referred to as angle that only one side or end thereof contacts the winding drum and such contact is outside the travel limits of the moving paper web. From this position the reel is lowered with suflicient contact or drag on the drum to induce it to first rotate and then attain a rotative speed corresponding to-that at which the drum is rotating. The full length of the reel is then lowered into as nearly a parallel position with the drum as possible and into contact with the paper web passing over the drum.

The operation of contacting one end of the winding reel with one end of the rotating drum for reel starting purposes and then endeavouring to lower the full length of the reel into even contact with the moving paper web frequently cracks or breaks the edge of the web or sheet and in the event these cracks or breaks are of a- 7 web-straddling means which may be started and brought up to rotation at the required winding j speed before being fully brought into engagement with the web thus avoiding cracking ,or

2 r, breaking the paper web and the resulting substantial loss of paper, and waste of time and further eliminates the danger of workmens clothing being entangled therewith. v

Yet a further object of the present invention is to provide a device of this character which is simple and ruggedinform and one that will the more satisfactorily perform the functions required of it.

Having regard to the foregoing and other ob-- jects and advantages which willbecome apparent as the description proceeds, the invention consists essentially in the novel combination and arrangement of parts hereinafter described in detail and illustrated in the accompanying drawings in which:

Figure 1 shows anend view of anembodiment of the present invention which for purposes of illustration is shown in operative position on the dry-end of a paper machine.

Figure 2 is a plan view of the present invention' shown in detached form.

Figure 3 is an enlarged sectional view taken on the line 3-3 of Figure 2, and

Figure 4 is a section taken on the line 4-4 of Figure 3,

Referring now to the accompanying drawings disclosing an embodiment of the present invention and wherein like letters and numerals of reference designate corresponding parts in the different illustrations, the letter A indicates the present invention as a whole while the letter B indicates a fragmentary portion of the dry-end" of a'paper making machine.

For operative purposes the winding reels A are removably supported in any suitable type of end bearings l5 by arm means IS, the arms l6 being swingably connected to the frame of the paper making machine B as at IT. Suitable and well known mechanism is provided for swinging arms IS with reels A thereon toward winding drum l8 for purposes of starting and then bringing the reel up to proper rotative speed as will be later explained.

The winding reel herein disclosed includes a casing or shell IQ of appropriate length and suitable material having end supporting shafts 20 all of which is known in the art.

In accordance with the present invention, each end of the winding reel A is provided with yieldably mounted contact collars or discs 2! which body of reel l9 so that when the reel A is lowered into contact with the winding drum I8 for purposes of starting the rotative movement of the reel, the collar members straddle the paper web and contact the drum outside the limits of such paper web. Here it is considered proper to mention that by reason of the annular structure of the disc members, their rounded edges and the fact that they protrude a limited extent beyond the surface of the reel body, eliminates the danger of workmen becoming entangled therewith.

Each of the collar members or discs 2| is constructed with a central bore or openin 22 the diameter of which is greater than the outside diameter of the shafts 20 while a series of concentrically arranged bores or openings '23 are formed between the inner and outer peripheries of the collar members. Within the openings 23 of the collars I mount annular sleeves 24 composed of rubber or like yieldable material while within the core of the members 24 I mount metallic spacer rings or sleeves 25 that, are just a little longer than the thickness of the discs 25 and yieldable sleeves 24.

The means for mounting the collar members 2| on the ends of the reel A to efiect a floating mounting comprise end plates 26 which are fitted over the shafts 20 at the outside of collars 2i and are connected to the reel A as by countersunk bolts. or the like 21. These bolts it is observed extend through the metallic spacer rings,- with their necessary margin of length over the thickness of the collars 2 I, and into the ends of the reel head, thereby maintaining the collars in floating relationship to reel A.

With the resilient members 24 disposed between the collar or disc members 2| and bolts 27, the mountings will yield when a pressure is imposed on the outer periphery of the discs or collars however in the absence of a peripheral pressure the discs are maintained in a normal position such as seen in Figures 2 and 3, so that they en- ,gage the ends of the rotating drum for reel rotating purposes without contacting the paper web.

From the foregoing it will be observed that the full length of the reel is lowered parallel with the drum 18 until the disc members contact the drum outside the limits of the moving paper wab and the reel is quickly brought up to rotative winding speed. With this accomplished the reel is lowered into tight parallel contact with the moving paper web, the yieldable mountings enabling the disc members to ride the drum in the same plane as the reel body. This precise and accurate lowerin of the reel enables it to move into tight, even contact with the moving paper web at a corresponding speed and without crack ing or breaking the paper sheet. Simultaneous with the lowering of the full weight of the reel, air jets are operated to break the paper web and, turn it on the empty rotating winding reel, without interfering with the continuous run of paper from the paper making machine.

Many changes may be made in the above and many apparently widely different embodiments constructed without departing from the spirit or essential characteristics of the invention. It is intended therefore that the present disclosure be interpreted as illustrative rather than restrictive and that all changes coming within the meaning and range of equivalency of the claims are intended to be embraced therein.
