H. A. W. WOOD WEB ROLL TAB May 5, 1936.

'Filed July 19, 1933 Patented May 5, 1936 PATENT OFFICE was non. TAB

Henry A. Wise Wood, New York, N. Y., assignor to Wood Newspaper Machinery Corporation, New York, N. Y., a corporation of Virginia Application July 19, 1933, Serial No. 681,076 In Great Britain July 3, 1933 12 Claims.

. This'invention applies to that type of machine which is used in splicing web rolls and is particularly applicable to the webs used in news- Nper printing presses.

a -;In a web roll splicing chine, when one web roll is nearly run oil, a n w roll is brought up to sy nchronousspeed of the web and at the proper time the old web is pressed against the new roll and the splice is made. 1 In bringing this new 10 rtjll up to synchronous speed it is necessary not only to hold down the forward end of this new rojn so that it is not thrown off by centrifugal force or by air but to hold it on lightly enough so that, when the old web is applied to this new 1- roll, the point attaches itself to this old web without serious disturbance.

' objects of this invention are to provide air article of manufacture which may be easily attached to the point or points which are cusao 'toina'rily cut on the forward end of a new roll of paper and secured against the body of the roll, and which carries a weakened portion of predetermined strength which is severed when the point or points attach themselves to the old 25'' web; to provide for eliminating the inconsistenciee incurred in the former practice of holding a'jioint down with grease, and to provide a relatively firm means for holding the front edge "for any length of time, which will not lose its so adhesiveness.

Dther objects and advantages of the invention appear hereinafter. Reference is to be had to the accompanying drawing, in-which 5 "Fig. l is a view of a paper roll out with two points, each individual point being held by the a "topaster tab.

" 2 is a similar view of a paper roll'carrying a single point; 3' and 4 are detailed edge and face views of lthe tab and the preferred means by which the breaking point is'weakened;

5 shows a modified construction of the tab. and

45 'Flgs. 6 and 7 are views of modifications.

The present method of making the paster is to cut the end of the paper on the new roll at an angle with the point leading forward and hold rauma flying oil. by little spots of grease at 50*eeveral points under its front edge and then along a line the entire length of the'cut slightly back from the edge. It frequently happens that this roll, after being prepared in this way, remains in position for some I timebeforethepasterismade. Insuchacase the grease loses its adhesiveness and, when the roll is loaded, wind is liable to get under the front edge of the sheet and cause it to fly off. This entails different kinds of damage and much delay.

Of course, it is necessary to hold the front edge-of the web against the roll temporarily in such a way that when the poster is made it will let go of the roll and allow the new web to be fed into the press without any material resist: 10 ance. This, of course, applies to those cases in which the paster is made without stopping the web or the press. According to this invention a relatively firm means is provided for holding the front edge for any length of time which will not lose its adhesiveness by the lapse of time. For this purpose paste is provided instead of grease and the strip is perforated so that when the paster is made it will break away.

The web roll can be provided with two or more points l 0 on the leading edge of the web as shown in Fig. l or with a single point as shown in Fig.

2. .In either case the points are attached to the roll by a strip of frangible material, as paper.

II to which two spots of adhesive, as paste or 26 glue, I: are applied at opposite ends and-on the same side and separated from each other. Between these spots and preferably at the center of the strip is a line of perforations it. These strips are applied to the points so that the line of per- 30 forations is beyond the paste points I! and the stripis pasted both to the point and to the next course of paper on the roll.

It will be seen from Fig. 3 that a side view of the preferred form of tab has the appearance 85 of an inverted Y. An extra piece of paper 9 is shown secured to the paper II at one end and having a spot of glue 8 on the inner surface. The insides of the prongs of the Y carry glue which when moistened and closed over the point 40 v of the web secure that end of the tab firmly to the point. The side of the single end of the Y which is next to the paper roll is covered with similar glue so that it may be attached securely to the paper roll. By the use of the line I! of paste over the tabs, they have an adhesive on both sides.

Fig. 4 shows at just what position the weakened part of the tab lies and illustrates one embodiment of the invention which comprises slits cut across the tab on an angle such that when a force is applied. to pull the two ends apart there is a tearing action on this weakened portion of the tab rather than a bursting action which would be present were these slits not made 66 at an angle. This tearing action insures a consistency of strength which is dimcult to maintain in the type of tab weakened by a straight row of perforations in a single line. The duplex portionoi the tab which comprises the leading edge of the new web has added stiffness because of its being double thickness and thus is useful in preventing the turning back of the leading edge.

In preparing a new roll for splicing, the operator cuts or tears his points, dampens the paste portions of his tab, encloses each point with the double end of the tab and smooths the paper down so that the other end of the tab attaches itself to the paper roll. A line of paste I5, preferably of the non-drying type, is then applied along the edge of the point or points, as in Figs. 1 and 2, and covers the doubled portion of the tab down to the breaking point. It sometimes happens that in the placing on of this tab or in the putting on of paste this weakened portion of the tab is accidentally broken or damaged.

A modification oi the paster tab is shown in Fig. 5 where the general Y shape of the tab is maintained but an additional feature is present in a detachable strip it which augments the weakened portion of the tab. This tab is put on as shown in Fig. 5 and will stand rough usage. The paste which is placed on the point by the operator is brought down over the duplex end of this tab and may cover a portion of the detachable strip. When the operation of putting on the paste is completed this detachable strip It is torn off whlch'leaves the two ends of the tab held together only by that predetermined strength. Thus this detachable strip serves two purposes: one, it allows the operator to place the tab on with less danger of breaking the weakened portion; and two, it demands less care in putting on the paste with the assurance of paste near the breaking point.

This invention has two particular advantages: different operators or the same operator at diiferent times would place on more or less grease which would make the holding-on strength vary, furthermore, grease varies materially in its holding-on power at diiferent temperatures and according to the length of time that it has been on the paper.

This is a permanent attachment, so to speak, taking the place of the usual grease spots. No amount of drying out will reduce its eifectiveness for this purpose. It is always ready for use and perfectly effective after once being applied.

The expiring web is pressed against the new roll which is rotating and the usual line of paste l5 placed along the outer edge of the loose end of the web, on the roll over'the tabs, sticks to the expiring web. The motion of this web away from the roll, or rather the rotation of the roll to swing the part of the strip Ii that is attached to the roll away from the expiring web, necessarily pulls the strip apart along the line of perforations l3. Half of the strip remains on the paper of the roll and the other half is attached to the leading end of the web on the roll and passes into the press with the expiring-web.

Figs. 6 and 7 show the elemental idea .of the tab with a weakened section reduced to its simplest terms. In Fig. 7 the weakened section is -'made up-of a series of slits perpendicular to the line of travel of the web.

This constitutes a simple and effective means for holding the new web roll in proper condition until it is to be used, no matter how long t at may be, and affords a sure means for separating the leading end from the roll when the paster is made. I

Although I have illustrated and described only a few forms of the invention I am aware of the fact that other modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in this respect otherwise than as set forth in the claims, but what I do claim is:-
