.6 Claims. 1

This invention relates to cement-applying rolls and is herein illustrated as embodied in a roll which comprises a plurality of members disposed end to end and bound together to make a substantially cylindrical structure.

It is Well understood that, in the application of coatings, such as adhesives, hereinafter termed cements, greater or lesser quantities are required for different kinds of work in order to get a good bond and, since the manufacturers of cement-applying machines must devise an arrangement which will be suitable for all kinds of work, it is desirable to have the applying roll of such machines constructed from a plurality of parts which may be assembled in different relations in accordance with the coating which is to be applied.

Accordingly, an object of the invention is to provide an improved built up, or assembled, applying roll which may readily be put together in different ways enabling the quantity of cement applied by the roll to be varied.

In accordance with features of the invention and as herein illustrated, the cement-applying roll comprises terminal portions at least one of which has a hub and intermediate annular body portions supported on the hub. These annular portions have notched peripheries, and interengaging means, such as a key and a plurality of keyways, are provided to effect either an alined relation or a staggered relation of the notches on the adjacent members when assembled. In the illustrated construction, dual keyways are provided on the inner peripheries of these intermediate members, and one keyway is radially alined with a notch while the other is radially alined with a tooth or land.

These and other features of the invention will best be understood from a consideration of the following specification taken in connection with the accompanying drawings, in which Fig. 1 is a diametrical section along the axis of the roll and showing the notches of adjacent sections alined;

Fig. 2 is a similar view showing the notches of adjacent sections staggered;

Fig. 3 is an elevation of the roll arranged as in Fig. 2; and

Fig. 4 is an angular view of one of the intermediate, annular cement-applying members.

The cement-applying structure comprises a terminal member ill having a hub l2 (Fig. 1) adjacent to one end of which there is a shoulder l4 forming one face of a flange l6 tapered at its periphery. Disposed on this hub l2 are annular applying members or body portions [8 having a series of notches 20 extending transversely of their peripheries and, as herein illustrated, the lands between the adjacent notches are in the form of sharp-edged teeth 22. The exact design of the corrugated peripheries of these members may be varied in accordance with the character of the work to be treated. These intermediate annular members l8 are held against endwise movement on the hub 12 by another terminal flanged member 24 held against rotation with respect to the first terminal member ID by means of a key 26 extending in a direction parallel to the axis of the roll and, as illustrated, taking the form of a pm.

Spaced selective positioning means are provided on the successive annular members to enable them to be alined so that the notches 20 in adjacent members are either in register or are staggered. These positioning means are formed on the inner periphery 28 of each annular member as keyways 30 and 32, one or the other of which cooperates with the key 26. It will be noted that each keyway 30' is adjacent to a notch 20 on the periphery of the applying members, whereas each keyway 32 is adjacent to an intermediate land or tooth 22. The radial positions of these two keyways with respect to the periphery of a member are shown (Fig. 4) by the dot-dash radial lines drawn in the plane of one side face of one annular member l8 and, from an inspection of this, it will be seen that the keyways are spaced by a distance proportional to the pitch distance between a land and an adjacent notch or an integral multiple thereof; in other words, the angle between the keyways may be the same as the pitch angle between a notch and an adjacent tooth or it may be a multiple of that angle. Viewed in another aspect, the distance between the keyways along the inner circumference has the same proportion to the distance between a notch and a land or a multiple thereof as the radius of the inner circumference bears to the radius of the outer circumference. When these intermediate members are assembled on the hub l 2 with the keyways 30 all in engagement with the key 26, then, the resulting structure will be arranged, as shown in Fig. 1, so that, on the periphery of the assembled roll, there will be rows of transverse notches extending across the periphery of the roll. It will be noted also that peripheral cement-carrying grooves 34 are formed between the tapered flanges of the terminal members I 0, 24 and the adjacent intermediate memhers I 8. Consequently, the terminal members are part of the cement-applying structure and may also be called terminal applying members.

This assembled structure is positioned on the reduced end portion 36 of a rod 38 and brought against a shoulder 40 thereon. It is clamped in 5 this position by means of a headed screw 42 hearing against the outer terminal member 24 and having a threadedqengagement with a 'socketinthe end of'the rod 38. To prevent rotation of theassembled structure upon the rod, a key in the form of a radially extending pin 44 is brought in-. W to engagement with a keyway 46 formed ,inside, the hub of the terminal member II]. when this roll is mounted in a cement-applying:machine;

(not shown), the rod 38 will berotatably-mounteda and may be either connected to orintegralwitha driven shaft in the machine.

If, on the other hand, the annular body portions [8 are assembled as shown in Figs. land-3;: then, the notches of one annular member I8 0 will beppositioned ,besidethe teeth ,22 of the,ad-, jacent member and will form on theperipherypf, the;roll ayseries of pockets oflimited axial ex tent which will receivecement from a suitable; source1and ,apply it to; the, work in apluralityof a 5 globules; Thereis, with ,this arrangement; no-1 lateral displacement oi the cement on; the roll by the pressure of-the work and,- consequently, a; greater quantity is-Htransferred to the; work thanv isthe case with the arrangement shown in Fig; 1,
