WILLIAM A. LORENZ, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE OTAKA FABRIC COMPANY, OF HARTFORD, CONNECTICUT, A CORPORATION OF CONNECTICUT.

rAP R-GRINKLING MACHINE.

Application filed September a, 1920. Serial No. mspa.

To all whom it may concern:

\ Be it known that 1, WILLIAM A. LORENZ,

a citizen of the United States, residing in Hartford, in the county'of Hartford and State of Connecticut, have invented certain new and useful Improvements in. Paper- Crinkling Machines, of which the following is a specification.

This invention relates mainly to papercrinkling or gathering of the kind disclosed in my pending application, No. 346,310,

filed December 20, 1919.

In said application, a web of paper is first gathered in widthwise direction by forming corrugations or fiutings therein. The corrugated paper is led over a periphery grooved cylinder or drum, around which it is advanced to a crinkling'element, which comprises a doctor-blade, whereby the corrugated paper is crinkled transversely, and

hence gathered longitudinally.

One of the objects of the present inven-' tion is to improve the corrugating element of the machine. In said application, the

- paper was advanced between opposing plates having converging grooves therein, whereby thepaper was corrugated longitudinally. According to one feature of the present improvements, the corrugating operation is divided into several steps, and one of the improvements is the use of a succession of pairs of co-operative grooved plates. The paper as it leaves the first pair is partially corrugated, and as it leavesthe second pair it is nearly 'or wholly corrugated. Thus there is less work done upon the paper by each pair of plates than heretofore, and the paper may be drawn easily through the first pair by the rolls, and may then. be drawn easily through the second pair by other rolls, so that the strain put uponthe paper by either pair of rolls is much reduced, liability of rupturing the paper is minimized or eliminated, and an improved quality of work is produced. The feeding rolls in each pair may be peripherally corrugated or grooved, the corrugations in one roll meshing with the grooves in the companion roll; and they may be used not only to feed the paper, but also to deepen thecorrugations-therein preparatory to the crinkling operation. Preferably a pair of corrugated or grooved rolls is placed in advance of the first pair of grooved plates, so as to bend or break the fibres and to start web.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure l is a plan of a double-gathering machine, showing the present improvements applied thereto.

Figure 6 is a fragmentary end elevation, showing the grooved drum periphery, and also showing the scalloped edge of the doctor-blade fitting in the grooves of the drum.

Figure 7 illustrates one of the pairs of feeding and fluting rolls. ,7

Figure 8 is an edge view illustrating the intermeshing of the ribs and grooves on the fluting or corrugating plates.

Figure 9 is a view similar to Figure 8,

but taken along the .-line 99 of Figure 1.

Fig. 10 is a view in longitudinal section through one of the corrugating plates, the

groove of which is more shallow at the in tween and is drawn along by a pair of rolls 17 18, at the left of the introductory roll 14. These rolls have rounded peripheral grooves 19, and are so arranged that the rounded ribs 20 in one roll-mesh with or rotate within the grooves 19 in the other roll, Figure 7, so that the paper'is primarily given a slight corrugation, and its fibres are weakened, bent or broken,-preparatory to further treatment. The first pair of rolls 17, 18, by forming shallow flutes, tends to gather the web or reduce its width, and this tendency is favored or facilitated by forming the initial ide roll 14 with a bulge, so that it is o greatest diameter at a midway point, as at 21, Figure 1, and tapers therefrom towards its ends.

From the first pair of rolls the paper advances between a pair-of horizontal fiuting plates 22, 23, Figure 8, each having converging grooves 24 therein, the ribs in each plate being within the grooves or between the ribs in the other plate. The convergence of the grooves is indicated at 24, Figure 1; and preferably each groove is of tapered form, as also shown at 24, Figure 1, and it may be more shallow at the introductory edge of the plate than .at the delivery edge thereof, so that the depth of the corrugations in the web, and the gathering-thereof widthwise, may increase as the web is drawn along between these plates.

The web is drawn between said plates 22, 23 by means of a second pair of rolls 25, 26, which have peripheral grooves 27 and ribs 28, these rolls intermeshing like the rolls 17, 18, and not only feeding theweb along, but also preferably deepening the corrugations therein. Inasmuch as only a part of. the corrugating is done by the first pair of plates 22,

23 there is no liabilit of excessive strain being placed upon the paper in drawing i through said pair of plates.

From the rolls 25, 26, the web advances between the plates of a second pair 29, 30, which have inter-meshing grooves and ribs, as seen at 31, which are converging and tapering, and are in the nature of continuations of the grooves and ribs in the first pair of plates 22, 23. By means of the second pair of plates the corrugations in the web are deepened, as at Figure 9, and the web accordingly is again gathered widthwise, as lllustrated diagrammatically at Figure 1.

The web is drawn through the second pair of plates 29, 30, by means of a third pair of ribbed and fluted or grooved rolls 32, 33, which may both feed the paper and also deepen the flutings therein, thus completing the final stage of the corrugating operation. It will be understood that the number of grooves in the upper roll32 is the same as that in each of the other upper rolls 25 and 17, and that the same thing is true of the lower rolls 33, 26 and 18. The grooves at 32 and 33 are closer together than those in 25 and 26. y The grooves in 25, 26 are likewise closer than those in 17, 18, so as to accord with the gradual widthwise gathering of the web as it pases through the corrugating or fiuting mechanism. The spacbringing it against a doctor-blade 35 and forming transverse crinkles or corrugations 36, the paper being delivered over a belt mechanism 37. i

The machine may be driven by a pulley 38, having a pinion 39 to mesh with a main driving gear 40 on shaft 41 of the main cyl-' inder 34. In order to avoid excessive pull on the paper by the drum, the three pairs of rolls already described are power-driven, so that the rolls in each pair of themselves are efficient in feeding the paper, and hence the work of advancing the same through the corrugating element is divided among several feeding couples, so that the pull exerted by any couple upon the paper is not apt to be excessive. Accordingly, the main driving gear 40 meshes with a pinion 42 fixed upon an axle 43 of feed-roll 33, and a pinion 44 meshing with 42 is fixed upon the axle 45 of the upper feeding'roll 32 of this couple. To rotate the couple 25, 26, there is provided an idle gear 46 meshing with 42, and a pinion 47 fixed upon a shaft 48 of roll 26 meshes with said idle gear 46; said pinion 47 also meshing with a'pinion 49 fixed on a shaft 50 of roll 25. From the gear 46, train of idle gears 51, 52,connects to a pinion 53 fixed on a shaft 54 of roll 18; said pinion meshing with a pinion 55 fixed a shaft 56 of roll 17.

The rolls of each pair may be provided with means for effecting fine adjustments of their relative positions, and for regulating pressure of the rolls upon the paper. As seen best at Figure 4, the end of each roll shaft is journaled in a bearing 57, which is pressed down by a pressure spring 58 upon the end of a screw 59. By turning the latter, the end of the roll may be adjusted to wards or from the companion roll; and the same adjustment may be effected at the other end of the roll also, so that the rneshin of the rolls may be made deeper or more s hallow, and the effect upon the paper varied accordingly. Pressure of the spring 58 is regulatable by a screw 60 having a lock-nut 61.

The grooved corrugating plates may be secured by set-screws 62 upon cross-rods 63, fixed to the-framework 64, 65 by'means of set-screws 66. The plates may be individually adjusted along the rods or across the machine, so as to bring .them into correct positions relatively to eachother and to the paper and to the sets of rolls.

The main crinkling drum or cylinder 34 is peripherally grooved at 67 to receive the corrugated sheet, the grooves and ribs of "the drum mesning with those of the feedroll 33. Between the introductory and delivery sides of' the drum, there' may be placed other power-driven pressure rolls, as 68, 69, correspondingly grooved for overcoming the tendency of the corrugated and therefore stiffened sheet to spring away from the drum, and for aiding in the feeding of the paper around. the drum. These rolls also tend to complete the corrugation of the paper and the requisite breaking or softening of the fibres. Each of these rolls 68 and ,69 may be provided with an adjusting device, asseen at Figure 4, including the screws (30 to regulate the pressure of the rolls upon the paper. 7 k

At the delivery side of the cylinder may be arranged a pressure roll 70, havinga soft rubber or other yielding periphery 71,

grooved at 72 to correspond with the ribs.

7 3 in the drum 34. This roll is placed close to the doctor-blade 35, and holds the paper firmly against'the drum to cause the stiffened paper to be crushed edgewise against the blade with sufficient force'to form transverse crinklings 74in the corrugations 75, Figure 1. By means of the device seen at Figure4, this roll may be adjusted towards and away from the'drum 34, and its pressure may be regulated by screws 60 acting on spring 58, so that sufficient gripping is secured upon the advancing web to enable it to be thrust against the doctor-blade with the force requisite for transversely crinkling the corrugations.

The doctor-blade 35 may have its lower edge formed with grooves or notches 76, Figure 6. tofit closely in the groovesand ribs in the cylinder 34, thereby efficiently stripping the paper from the cylinder, and

at the same time crinkling it in the desired manner. The lower edge of the doctor'- blade preferablyhas an abrupt face at its grooved portion, as seenat 77, Figures 2 and 5, to serve as an abutment against which the crinkling of the paper may be effected;

' and aboversaid abrupt face the blade may cuiwe for a distance concentrically with the roll 7 O and close thereto, so as to leave only the space necessary for the egress of the crinkled paper.

If desired, the pressure of the atmosphere may be also utilized for pinching the web to the crinkling roll 34. For this purpose, there may be provided a vacuum box 78 from which air is exhausted through a pipe 7 9. This box has end walls, also a light hand wall 80: the doctor-blade forming a part of the left-hand wall. The box is open at the bottom, and all of its walls fitclosely to the grooved periphery of the drum 34,,

to minimize leakage of air into the box.

The wall or side 80 extends down far into the bight of the rolls 33 and 34, to where the paper leaves the roll 33 and begins to said wall 80 is scalloped to fit the grooves in.

drum 34. Thus air may be partially exhausted between the paper and the roll 34,

and this condition may continue :until thepaper reachgs the doctor-blade 35..

For drying the paper as it passes around the drum 34, the latter may be supplied with steam through a pipe 81-having a horizontal portion 82 passing through the hollow axle 41 of the drum and leading to an out-let 83.

The axis 84 of roll 70 may be provided with a pinion 85. to mesh with the general drive gear 40, so that said roll is positively driven, and acts positively on the paper in driving the same against the doctor-blade.

The rolls 68, 69 may havep'inions 86and 87' meshing with the main gear 40, said pinions being fixed on the shafts 88 and 89 ofsaidv rolls, which renders them efficient,

Variations may be resorted to within the scope of the invention, and port-ions of the improvements may be used without others.
