Claims. (Cl. 242-65) This invention relates to a means for continuously ice y chine and thrown up and over the empty reel whereby winding rolls of material and has for an object to proi vide means for changing the winding material from a completed roll to a fresh roll without interruption in supply or change of speed in the winding material.

Many forms of machines are adaptable to produce and operate on a continuous web. Such machinery will naturally discharge the web in a continuous operation. In order that the web may be wound in practicable quantity upon separate reels it is necessary to discontinue the lwinding upon a reel which has received a predetermined quantity and to initiate winding upon an empty reel Vwithout stopping the continuous operation of the web producing or treating machinery. For example, in the paper industry a paper making machine produces a continuous web of paper and under ideal conditions a machine will not be shut down for several days. Similarly, paper coating machines are more eiciently run in a continuous manner and vto thisv end paper may be supplied `to them from a succession of reels which are so handled so as to splice the leading end of the uncoated paper to the trailing end of the spent reel. These splices may be made by any of the well known flying splice mechanisms and unless it is necessary to stop the machine for purpose Aof change of reels, the coating operation may be contin- -k u'ously performed in either of these examples as well as in any other instance. It is highly desirable to provide instantaneous transfer of the web from one winding reel to another.

Various types of reeling devices are known which are capable of handling a continuous moving web. One

widely used form is knownthroughout the paper industry 4as the Pope reel. Such a reel is shown in United States Patent No. 1,248,542. The present invention is particularly adaptable for use in conjunctionwith the Pope reel although, obviously, it is not limited in its use to such reel. For the purpose of description the invention will bef set forth in connection with the Pope reel.

In general the Pope reel comprises a driving drum which is rotated at a peripheral speed equal to the speed `of' movement-of the web with which it is to be used.

Empty reels are placed into frictional contact with the surface of the `driving drum and the leading end of the paper is secured in some manner to the empty reel whereby rotation of the driving drum will serve to rotate the empty reel land wind the paper therearound. When a -predetermined quantity of paper has been wound upon j,

the reel, it is necessary to shift the lled reel while it' the leading edge drops down upon the face of the paper progressing toward the reel. This serves to drag the leading edge into the nip between the winding reel and the driving drum and forms a bight having sucient friction to secure the web to the winding reel. From this point on the web of paper will be progressively wound upon the reel.

At an appropriate time the partially wound reel may be moved along the periphery in the direction of rotation thereof and brought to rest in a suitable bearing mechanism wherein it continues to wind in order to accumulate the predetermined quantity of web material. In the meantime a new empty reel is brought into position and is suspended just above the driving drum in a position ahead of the reel upon which the web is being wound. When the predetermined quantity is reached, it is necessary to sever the web at a point between the empty reel and the lled reel and it is necessary to direct the leading edge of the web around the empty reel to initiate winding upon the same.

The usual steel roll used as empty reels has been replaced by a rubber covered roll. The rubber covered roll has many advantages among which is no scoring or marking of reel drum surface. When the empty is lowered onto rotating reel drum, the friction often breaks the web. This web breaking results in considerable loss of paper.

Accordingly, it is an object of this invention to provide means for bringing the empty reel to substantially the same peripherial speed as that of the driven reel drum.

Other and further objects of the invention and the advantages of the same will be pointed out hereinafter and indicated in the appended claims or will be obvious to one skilled in the art upon understanding the present disclosure.

While one embodiment of the invention has been described in more or less detail to comply with the requirement of the statute, it is nevertheless desired that the detailed description be considered merely as illustrative and not as limiting.

In the drawing:

Figure l is a top plan view of the reel starter with parts broken away;

Figure 2 is an end view of the invention with parts broken away; and

Figure 3 is a sectional view of a part of the winding drum.

Referring to the drawing, the reel drum 10 is suitably rotatably mounted on a shaft, such as indicated at 12, which extends from the opposite ends of the reel or driving drum 10. The driving drum 10 Iis rotated by driving vshaft 12. This shaft 12 may be driven as shown in Figure 2 of United States Patent 2,475,480 or by any other suitable driving means. A web of material 14, such as paper, is delivered from a web making machine, calender ing or other treating apparatus and is then passed over the surface of the reel drum and wound upon a reel core or winding roll 16, which may be similar to thatshown in Patent No. 1,925,670, to form a reel of paper or the like. The reel core 16 having paper or other material wound thereon is, of course, suitably supported by reel arms 60, to maintain the circumference of the roll of paper or other material being wound thereon in engagement with the surface of the reel drum 10 in accordance with more or less common practice as shown in United States Patent 1,923,670.

While one reel is being formed on reel bar 16, another reel bar 18 is positioned above the paper web 14 and adjacent to reel drum 10 so that the reel bar or winding 3 roll 18 is clear ofthe reel drum 10 but supported through the reel bar bearing housing mounted on stub shafts 20, which extend from opposite ends of the reel bar 18. The reel bar` bearing housings are supported by yokes 21 and held from rotating by

guide sides

22 and 24 in the yokes 21. The

yokes having sides

22 and 24 are suitably hinged to bring the reel bar 18 first in contact with the Hat belt 26 and then the surface of reel drum 10 through gears cut on the yokes and driven through pinions 58. This is done in accordance with more or less common practice for example, as is shown in United States Patent 1,923,670.

The contact of the reel bar 18 with flat belt 26, which is being driven by reel drum 10, transfers rotation to reel bar 18 until reel bar 18 is rotating at the same peripheral `speed as reel drum 1'0. The reel bar 18 is then brought in contact with the paper web 14 passing over reel drum V at some predetermined time. The web 14 is then transferred from the reel drum 10 to the reel bar 18 by some suitable means.

The remainder of the cycle consists of removing the completed reel formed on reel bar 16, transferring reel "bar 18 from the yokes to reel arms 60 by rotating the yokes. The sides 24 of the yokes are suitably hinged to facilitate this transfer of the reel bar 18 from the yokes to `the reel arms 60. The yokes are then returned to a suitable position to where another reel bar can be positioned into the yokes and the cycle repeated.

The reel drum 10 has a notch or groove 25 formed along one edge. This groove 25 is for the reception of a belt-like member 26. To insure that the belt remains in the groove 25, a stop member 27 is attached by suitable means 31 to the side of the Vreel drum.

Pulley V28 is xed on cross member 33 in a suitable position to provide suicient belt wrap of belt 26 on the `reel bar 18 to provide for spinning the reel bar while still -clear of the web 14. It is preferable, but not necessary, that the pulley 28 be adjustable in height above the reel drum -10 and this may be accomplished through the means of hand wheel 34 and stem 35, which is operatively connected to reel support members 30.

Frame members 54 which are connected to plate 56 have upwardly extending portions or ears 38 which support belt pulleys 36. The sides of frame member 54 have elongated openings 23 therein, which are adapted to slide blocks 50. Slide blocks 50 are bearing members for take-up pulley 40. To the blocks 50 is attached cable 42 by attaching member`48. The cable 42 passes over pulley 44 and has attached thereto weight 46. This arrangement provides for the variations in belt length during the -startingcycle and also maintains a fixed tension on the vbelt 26 at all times.
