(Cl. 164-1'l) 2 Claims.
This invention relates to a method of converting paper board or the like.
In converting paper board or the like webs from a jumbo roll into smaller rolls of desired widths, it sometimes occurs that the web section of one of said smaller rolls is too narrow in width to be of use in the particular shop where the converting operation takes place. It, therefore, becomes necessary to dispose of such narrow rolls either by selling them to another shop having facilities for using a web section that is relatively narrow, or by reworking the material back into the board making machine. Either form of disposal involves'a loss.
The main object and feature of this invention is to provide a method whereby two or more narrow web sections can be converted into a single and wider section.
In the accompanying drawings the invention is disclosed in several concrete and preferred forms in which Figs. 1, 2 and 3 are perspective diagrammatic views of two web sections having overlapping marginal portions showing successive steps of the method;
Fig. 4 is a fragmentary view, partly in section, of a cutting roller acting on the overlapping marginal portions of the web sections;
Figs. 5 and 6 are plan views of the overlapping marginal portions of two web sections showing different conformations of the cutting line indicated in Fig. 2;
Fig. 7 is a diagrammatic view of an apparatus whereby the method can be performed;
Fig. 8 is a fragmentary plan view of two web rolls from which the single web is to be produced; and
Figs. 9 and 10 are diagrammatic views of other forms of apparatus whereby the method can be performed.
Referring to Figs. 1 to 3, the reference characters I and 2 indicate two sections of paper board with their marginal portions 3 and d brought into overlapping relation. Said overlapping marginal portions are then slitted simultaneously on a line 5 extending generally in a longitudinal direction but having transverse deviations in alternately opposite directions as shown, line 5 here being of an undulating character. In this way surplus trim strips 6 and l are severed from the marginal portions and, in said marginal portions, there are produced complementary indentations 8 and projections 9 that are interengageable. The surplus trim strips 5 and l are then removed from the marginal portions,-and the marginal portions are brought into the same plane with the complementary indentations and projections in interengagement, thereby associating the edges of the sections.
The method iscarried out while the web sections are advancing under tension at substantially the same speed. In Fig. 'I is disclosed a winding machine, having a slitting attachment, to be used in case it is desired to wind the united sections into a single roll of material. As there shown, Ill and II indicate two shafts that support web rolls I2 and I3. These shafts are in different planes, that is I0 is somewhathigher than I I, and the web rolls are so positioned (Fig. 8) that web section I, coming from roll I2, overlaps web section 2 coming from roll I3. Web sections l and 2 are brought into contact with each other and pass around smooth-faced rotatable platen roller I l and engaging therewith is a rotatable slitting element I5. Platen roller it is positively driven and extends the entire distance across the machine but slitting element I5 is rotated by engagement with platen roller M and is so located transversely as to engage the overlapping marginal portions of web sections 5 and 2. Cutting surface I6 (Fig. 4) of the slitting element is here so shaped as to produce line 5 of Fig. 2. I1 and I8 indicate two winding drums rotating in the same direction on which rests wound material I9 carried by winding shaft 20 displaceable in an upward direction as the diameter of the wound material increases in a well-understood manner. 2I indicates a top pressure or riding roll extending across the entire width of the machine. The overlapping marginal portions of web sections I and 2 having been slitted by element I5, said web sections pass upwardly and a stripper 22 removes surplus trim strip l. The web sections then pass to front winding drum N, then to rear winding drum I8, and around with the wound material I9. Associated with top pressure roll 2I is another stripper. As here shown, surplus trim strip 5 is defiecteci by means of an idle roller 23 into conduit 25 to which an air suction device (not shown) is connected. In this manner, after the overlapping marginal portions have been slitted, the surplus trim strips are removed and the marginal portions are brought into the same plane with the indentations and projections thereof in interengagement. Apparently the tension exerted by the winding machine on the two web sections tends to bring the marginal portions into the same plane, but the pressure exerted by the various drums and rollers also assists.
The two web sections are thus wound into a single roll on the same shaft.
The shape of cutting edge I5 of slitting element l5 and consequently of line 5 may take many forms. In Figs. 5 and 6 are shown, as examples of variations, slitting line 5:: which is highly irregular in shape, and slitting line 5b which is an'gular rather than undulating.
In Fig. 9 is shown a modification of the invention in which the marginal portions of the web sections are brought into the same plane before they reach the winding machine. As there indicated, the web sections after being slitted by slitting element I54: and platen roll Ma pass upward where a stripper 22a removes surplus trim strip 1, after which the web sections pass over rollers 25 and 26. Adjacent the latter is a stripper 21 that removes surplus trim strip 6, and the web sections then pass between rollers 28 and 29 by which time the marginal portions of the web sections have been brought into the same plane. The associated web sections then pass to winder 30.
In Fig. a still further modification is shown in whichethe web sections are not wound into a roll. Starting here with rollers 28a and 29a which correspond to rollers 28 and 29 of Fig. 9, the web sections, after being softened by a suitable device (not shown) pass to corrugating rollers indicated diagrammatically at 3|. The corrugated web thus produced may thereafter be treated in any usual manner desired and may either be cut into sheets or wound loosely into a roll.
I claim:
1. The method of associating the edges of two paper board web sections while they are advancing under tension at substantially the same speed which consists in: bringing marginal portions of the two web sections into overlapping relation; slitting both of said overlapping marginal portions simultaneously on a line extending generally in a longitudinal direction but having transverse deviations in alternately opposite directions to thereby sever surplus trim strips from said overlapping marginal portions and to produce in the latter complementary and interengageable indentations and projections; removing said surplus trim strips from the marginal portions; and bringing said marginal portions into the same plane with the indentations and projections in interengagement.
2. The method of associating the edges of two paper board web sections while they are advancing under tension at substantially the same speed and producing therefrom a single roll of material which consists in: bringing marginal portions of the two web sections into overlapping relation; slitting both of said overlapping marginal portions simultaneously on a line extending generally in a longitudinal direction but having transverse deviations in alternately opposite directions to thereby sever surplus trim strips from said overlapping marginal portions and to produce in the latter complementary and interengageable indentations and projections; removing said surplus trim strips from said marginal portions; and winding the web sections on the same shaft.
MOSES M. MARCUSE.
