Oct- 16, 1934- H. H. PROVENCE CLOTH WINDING BOARD Filed March l5, 1933 l l l I l l u l grs/vented: HHPrm/@nce Patented Oct. 16, 1934 c 1,977,144 onora wiNnrNG BOARD Herbert nrroverice, Greenville, s. o. application Martina 193s, serial No.' 660,970 i-oiaims. (C1. 20e-50) invention relates to winding boards. com.-` m'only' used as` cores andupon which bolts of cloth maybe wound. The general object lof this invention is toprovide a winding'board which may be veryl cheaply made of laminated fabric such as laminated pasteb'oard or the equivalent thereofand yet which isA rigid and which is reinforced across eachend to strengthen the ends of the board against crushing and bending and I@ for the further purpose of thickening the ends ofthe board or core so as to permit the attachment of labels thereto and provide a relatively large space at the ends of the' board for the attachment and presentation of said labels.

' A further object is to provide a winding board of this character inwhich the boardwtoward its ends is gradually increased lin thickness so as to prevent material woundv on the board from being n creased or wrinkled and a still further object 2011s tol provide a board so constructed as to permit the use ora light weight material for thebody and so constructed that there is no need for the mach-iney operator to be particular about which side of the board is placed on the winderA frame sincel both sides are alike, thus saving much time in winding the cloth.

Other objects will appear in the cou-rse of the following description. n

My invention is illustrated in the "accompanying drawing, whereinz` 1 f l Figure 1 is a perspective View of a board constructed in accordance with my invention;y

Figure 2 is a longitudinal section on 'the line 2 2 of Figure 1; V

Figure 3 is a fragmentary transverse section on .the line 3 3 of-Figurel';

Figure i is a fragmentary sectional View of one end of a board showing a slightly modified con-J struction. g Y l As shown particularly well in Figure 2, `the body of the board comprises aweb 10 of light weight material such as more orless stiff and rigid pasteboard, the pasteboard being laminated or not as may be found best and having a 'thick-Y ness at its middle of approximately one-eighth of an inch. As before remarked, the body-portion tent and then the two sheets are split or separated at their ends and disposed between these split.

ends or separated ends is a transversely extending reinforcing strip 11 which may also be of laminated stock or may be of solid, relatively thick stock.. The two thicknesses of the web 10 and the intermediate strip ll at each end of the board are then stapled to each other by staples 12 or otherwise intimately connected tov each other. I do not wish to be limited to the use of staples as other means might be used for holding the strips in place in the ends of the boards.

As before remarked, the web 10 will have, under ordinary conditions, a thickness of approximately one-eighth of an inch while theends of the board in. actual practice will have an average thickness of live-sixteenths of an inch so that a relatively Wide label designated 13 may beraprplied to. one

or both endsv oi the board, or to embrace the end;v

a reinforcing strip is applied to the exterior faceY or faces of a winding board, there is a great lia-4 bility ofthe cloth` being wrinkled and-sometimes suchboards tear the cloth badly. -With my board, the cloth` may ybe wound to the extremities of the board so that the extremities ofthe boardare `flush with the ends of the bolt without any liabil` ity of thematerial being wrinkled ortorn.

The construction of my board permits the use of. a light weight material for the body, yet the SIR ends are suiciently strong and thick to hold the.

cloth properly ,andY to show up to advantage the printed .labels 13 often used on the ends. Light boards are less costly than boards having a thickness equal to the ends of my boards, they reduceA the cost of transportationbecause of their light. nessand they give a nshed appearance to the bolt of .clothequaling that of cloth Wound on heavy boards. Y

' In'actual use, these boards are ordinarily about eighteeninches long and are used to wind cloth approximately thirty-five inches wide. i is' doubled which makes the actual width as wound onfthe board seventeen and one-half inches. Strictly speaking, therefore,` the n cloth would hardly reach to the extreme thickened ends of the board and would be wound around ther-middle portion of the board. In actual practice, however,the clothdoes not wind absolutely true` and becauseof the stretch, weaves from side to side slightly. Thus it actually covers the entire board including thevrz-iinforcedv ends but the full thick-- ness of the cloth is not at both ends because the The cloth` -I are slightly split at the ends, thus making it easy entire thickness of the bolt does not cover the ends, there is no noticeable difference in either the thickness of the bolt or the smoothness because of the slight increase in the end thickness but with these gradually thickened ends, there is no tendency for the cloth to slide oif, that is, slide inward. Where reinforcements in the form of strips are disposed upon the outside faces of the ends of the board and particularly where reinforcing strips are placed only on one side of the board at the ends thereof, there is a tendency for the cloth to slide off of the reinforcing strips, causing wrinkling in the middle portion of the cloth. This trouble is not experienced withmy board because of the gradual sloping surface on each face of the board inward from theextreme thickness of the ends of the board to the inner middle portion of the web.

One of the distinctive advantages of this construction also resides in the fact that there is no need of the machine operator being particular about which side of the board is placed on the Winder frame since both sides are alike. This saves time in winding the cloth, whereas if reinforcing strips are placed on the board on one side, the operator must take care that the board is properly placed in the Winder frame.

While I do not wish to be limited to any particular manner of forming this board, yet preferably it is made of even plies, as for instance, two plies or four plies, so that there will be a joint of glue at the middle of the thickness of the board. Each end of the board is then split after the board has been out to the desired size and the reinforcing strips 11, which may be of pulp board, wood, pasteboard or other material are then inserted in the split ends, these strips 11 being-ofany desired thickness depending upon the thickness which is wanted for the ends of the completed board.v

These strips l1 are then stapled, glued or otherwise fastened in, serving the double purpose of rein forcing the end of the board against bending, and making the end of the board thick enough for the label to be properly supported and look well. The labels might be attached at the same time that the strips 11 are inserted. The insertion of the strips 1l act to spread the plies of board on each side to form a sloping surface from the thick end to `the thinner center.

It is to be understood that the board or web 10 is what may be termed a solid board, the ends being split inward for a short distance and the reinforcing members 11 inserted in the split ends.

If it were possible to secure a piece of pulp boardv of sufficient thickness and made in one solid piece; the extremities of this solid board would be split and the reinforcing members inserted. It is not practical, however, for paper mills to make a solid board in one piece and, therefore, thinner boards are taken glued together in layers, and under great pressure, and in this way form the equivalent of a solid board. It is this laminated board which is practically solid which is illustrated in Figure 2'.-

It is often the case that these laminated boards to separate these ends and insert the reinforcing members 11', but this is not at all necessary'as I have used boards containing an uneven number ,of layers and split the center layer for inserting' the strips 11.

The cloth wound upon this board goes approximately to the ends but due to the fact that there is a lcertain amount of stretch in the cloth, the

slight slope from the thick ends to the thin middle portion does not give any trouble when winding either as regards wrinkling or bulging. It will be noticed, however, that this sloping portion of the board is very short with reference to the entire length of the board which is shown most fully in Figure 1. If these slopes extended further inward toward the center of the board to or nearly to the middle of the board, there would be trouble in winding the cloth. It is tobe noted, therefore, that by Vfar the greater portion ,of the board is absolutely flat and of even thickness and that only at the end is there a gradual thickening of the board from a thickness of one-eighth of an inch toa thickness of approximately ve-sixteenths of an inch and the upper and lower surfaces of the board extendtofthe ends without any shoulders, breaks, `or other solution of continuity. This can only be-achieved by splitting a board or thin web at the ends and inserting the strips 11.

I do not wish to be limited to the idea of splitting the ends of the board and inserting the strips 11 as it is entirely possible to make the board initially with gradually thickened ends as shown in Figure 4 where a board is illustrated in which theends 11a are thickened and made out of solid stock. Neither do I wish to` be limited to the particular form for the strips 11 as these may be uniformly cross-sectional or somewhat wedge-shaped, if

desired. l v
