6 Claims. (01. 164- 6) f This invention relates to a roll for handling paper formed of a light-weight metal such as an alloy of aluminum.
A main object of the invention is to provide 5 a roll built up from sections cast separately, but assembled and reinforced in such a way that the completed roll is suificiently strong and rigid for the intended use.
This and other objects and advantages of the 1' invention will become apparent as the descrip-' tion proceeds.
While a preferred form is disclosed herein for purposes of illustration, it should be understood that various changes may be made in the struc- 15 ture and arrangement of parts without departing from the spirit of the invention as herein se forth and claimed.
In the drawing:
Fig. 1 is a longitudinal cross-section of a paperroll embodying the invention, taken on line l-l of Fig. 4.
Fig. 2 is a perspective of one of the cup-shaped members of the paper roll.
Fig. 3 is a perspective of the support disc.
Fig. 4 is a section on line 4-4 of Fig. 1.
Fig. 5 is an enlarged section showing the cutter member held in the dovetail groove.
This invention relates primarily to the roll used in the final operation of a paper board machine. These ro-lls take the board from the conveyor and are of relatively large size, one exam- Y ple being 104 inches long with a diameter of 45 inches.
Formerly the only satisfactory material for these rolls was wood, and each roll was a solid cylinder cut from a selected tree. These wooden rolls were expensive to produce, required great care in handling and storage, and had a relatively limited life. Ferrous materials cannot be used because they do not form a surface to which the paper will adhere. Light-weight alloys do form suitable surfaces, but to cast a one-piece roll of this size from them is very diflicult and expensive.
The present invention provides a roll in which a plurality of separate sections are secured together to form a unitary roll, the separate sections being of such a size and shape that they can be cast conveniently.
In the drawing the separate sections are indicated by the reference numeral I0, and as is clearly seen in Fig. 2, each of these sections is of general cup-shape with a bottom H, a cylindrical wall l2, and an open end surrounded by a rim l3. The member is reinforced by a plurality'of triangular webs M which are radially arranged and which'are connected with the bottom I l and the side wall l2. In order to lighten the structure, openings I5 are formed in the bottom ll.
The roll illustratedis formed by securing together four of the cup-shaped members Hi, the. three at the left-hand. part of Fig. 1 being partially'nested together while the one at the righthand end of Fig. 1 is reversed so as to have its open end confronting the open end of the last cup-shaped member of the nested series. This arrangement is used in order to bring a bottom H of acup-shaped member at each end of the roll for purposes of support.
Special arrangements are made to provide radial support for the rims l3 at the openends of the cup-shaped members I (I. For the partially nested seriesof members In this support is provided by fitting each rim |3over a shoulder IS on the adjacent member I0. At the righthand of. the roll where two of the cup-shaped members confront each other, thus bringing two of the rims l3 into contact, each of the rims l3 fits partway over a support disc I1 which may have the shape of an open spider as shown in Fig. 3.
Each of the cup-shaped members l0 and support disc I! is formed with an aperture toaccommodate shaft l8 which supports the roll. A plurality of through bolts l9 are used to draw the cup-shaped member tightly together to form a unitary roll. The surface of the roll can be suitably finished in the same manner as though it were a single homogeneous casting, and since a very strong compression is exerted on the members by the through bolts I9, it is practically impossible after the roll has been finished to detect that it is composed of a plurality of separate sections.
In the operation of paper rolls of this type it is desired to have a cutter groove extend axially of the roll. In the present invention each of the cup-shaped members In is formed with an undercut groove 20 and a suitable conforming groove 2| is formedin the support disc II. The parts are assembled with these grooves in'alignment, and a wooden grooved strip 22 is then driven longitudinally into the groove. When it is desired to sever the paper board coming from the roll a wooden knife is drawn across it following the groove in strip 22. The paper board coming from the conveyorpasses under the roll and is carried up over the top of the roll, but does not wind around the roll since the end is cut offas soon as the groove 22 presents itself.
The cup-shaped members I and support disc H are preferably formed of a suitably non-ferrous material, such as aluminum, magnesium, or alloys containing them. A preferred material is an aluminum alloy having the following percentage composition:
The through bolts [9 are preferably made of a strong ferrous material.
The roll of the present invention can be economically produced, it is light and strong and since it is not subject to warping or cracking will last indefinitely. Other advantages of the invention will be apparent to those skilled in the art.
I claim:
1. A roll for handling paper comprising a series of cup-shaped members arranged in partially nested relation with the rim of each cup-shaped member interfitting with a shoulder formed on the bottom of the adjacentcup-shaped member, an end cup-shaped member arranged with its open end confronting the open end of the last cup-shaped member of the series, said end cupshaped member and said last cup-shaped member having their rims interfitting with a support disc, a plurality of through-bolts binding the cupshaped members and the support disc together to form a unitary roll, the peripheries of the. cupshaped members combining to form a uniform,
' cylindrical periphery for the paper roll.
cup-shaped members being arranged in partially nested relation with the rim of each cup-shaped member interfitting with a shoulder formed on the bottom of the adjacent cup-shaped member, an end cup-shaped member arranged with its open end confronting the open end of the last cup-shaped member of the series, said end cupshaped member and said last cup-shaped member having their rims interfitted with a support disc, a plurality of through bolts binding the cupshaped members and the support disc together to form a unitary roll, the peripheries of the cupshaped members combining to form a uniform, cylindrical periphery of the paper roll.
3. A roll for handling paper as specified in claim 2 in which each cup-shaped member is reinforced by a plurality of triangular webs, each Web extending along the bottom and side wall of a cup-shaped member.
4. A roll for handling paper as specified in claims 2 in which the roll is formed with an undercut groove extending axially across its periphery and is provided with a Wooden strip secured in said groove.
5. A roll for handling paper comprising a plurality of cup-shaped members formed of lightweight metal, the rim of each cup-shaped member being supported byan interfitting engagement with an adjacent part, the two end cup-shaped members being disposed with their bottoms forming the ends of the roll, a plurality of fastening members binding the cup-shaped members together to form a unitary roll, the peripheries of the cup-shaped members combining to form the uniform cylindrical surface of the roll.
6. A roll for handling paper as specified in claim 2 in which each cup-shaped member is reinforced by a plurality of triangular webs, each web extending along the bottom and side wall of a cup-shaped member, and in which each of the cup-shaped members and the support disc is formed with an opening to accommodate a shaft.
