15 Claims.

My invention relates to an attachment for corrugating machines, such asare usedin the manufacture of corrugated fiberboard. It has for one of its objects the application of oil to the periphery of one or more of the fluted rolls employed in forming the corrugated component of the sheet.

Another object of my invention is to polish the surface of the roll or rolls and to remove therefrom adhering foreign particles, such as fiber detached from the sheet of material operated upon.

In carrying out my invention, in its preferred form, I employ a rotary member meshing with. the fluted roll to be oiled and cleaned, a portion of the periphery of said rotary member being formed of porous material to which oil is supplied. Further, I impart to said rotary member a reciprocating movement in the direction of the length of the fluted roll to polish its surface. I still further provide the rotary member with peripheral grooves in which fiber or other foreign matter on'thesurfaces of the rolls is collected due to the combined rotary and longitudinal movements of the device.

In the accompanying drawings, which illustratean oiling and cleaning attachment made in accordance with my invention, Figure l is'a cross section of a portion of a corrugating machine to which my attachment is applied; Figure 2 is a plan view of the attachment; Figure 3 is a longitudinal section through the oiling roll and adjacent parts; Figure 4 is a cross section ofthe oiling roll, showing a modification; Figurefi is an edge view of one of the oil conducting discs used in the modified form; and Figure 6 is an enlarged longitudinal section through a portion of the oiling roll, showing the application of one of the oil conducting discs.

"In Figure l, I have shown a portion of one type of con'ugating machine to which my atfrom which the finished product is produced This sheet, indicated by thebroken line A, is

led over the moistening roll 3 and thence over the top of roll 2 down between rolls l and 2 where the corrugations are formed. After passing around the lower part of roll I, .where silicate is applied to the tips of the corrugations by a transfer roll I, it is united to the lining sheet,

indicated by the broken line B, by the action of pressure roll 5. The lining sheet is led to the roll 5 overs guide roll, 6, and the finished product is led from between rolls I and 5 to discharge guide roll 'I carried in brackets I on the frame of the machine.

In the form of corrugating machine shown, my attachment is most conveniently mounted on a rockshaft 9 journaled in the brackets 8 carrying the discharge guide roll. Keyed to the shaft 8 are arms l and H forming the end members of the frame of my attachment. Arms i0 and H are connected by bars i2 and I3 to form a frame which extends substantially throughout the length of the fluted roll I.

Mounted in the frame is the oiling roll, the i0 center of which is formed of a tubular member l4 closed at one end by plug having an extension journaled in the arm II and at the other by a plug is having an extension journaled in the arm H. The tubular member forms the oil, 15 reservoir of the device. Oil may be supplied to the reservoir through a central passage il in the plug 66, the outer end of the plug being provided with a threaded nipple I l for connection with an oil applicator of the grease gun type. The to plug it is preferably provided with a central passage IQ to permit the escape of air when the reservoir is filled. It will be understood that. the reservoir must not be fllled to a point above the openings ll and H9 or the oil will escape through these openings.

4 Mounted on the tubular member M are the oiling elements each comprising a central part 20 of felt or similar porous material and a pair of end plates 2| of more rigid material, such as fiber. The object of the end discs is to prevent spreading of the felt and to provide sumcient rigidity of the oiling elements to permit the transmission of motion from them to the reciprocating mechanism hereinafter described. The peripheries of the oiling elements are fluted to correspond with the fluting of the roll to which the device is applied so as to make intimate contact therewith when rotating in mesh therewith.

'The several oiling elements are held in align- 40 ment by being splined to the tubular member M by means of a key 22 entering corresponding key-ways in the elements. Each of the felt parts 20 may be formed of a single block of material, as shown in Figure 2, but for convenience in manufacture each part is preferably formed of a number of felt discs which may be convenient- 1y stamped from sheet material. In Figure 3 I have shown each part 2| as formed of six such discs. The individual oiling elements are separated to form peripheral grooves between them by spacing discs 23. These spacers may be made of felt to convey oil along the outer faces of the fiber discs 2| but thisis not essential, and the spacers may be of non-porous material if desired. Oil is admitted to the porous portion of the oiling roll through openings 24 in the tubular member I4 and thence passes to the periphery of the roll where it is applied toth'd-surface of the corrugating roll I.. The plugs may be provided with, Q

fiO

grooves 25 aligning with the openings 24 to permit oil to be supplied nearer the ends of the roll than would otherwise be possible.

In some cases it might be found advisable to provide means for delivering oil to the porous material at points adjacent the periphery of th oil roll. In such case I place between each pair of felt discs 20, or at least between some of them, a thin metal disc 26 having stamped therein radial grooves 21, alternate grooves preferably projecting from opposite sides of the disc. When such metal disc is positioned between two of the felt discs 20, as shown in Figure 6, it will be imbedded between the discs and the grooves 21 will provide radial oil passages 28 to convey oil from the reservoir to points adjacent the periphery of the felt discs.

Carried by or formed on the plug I5 is a gear wheel 29 meshing with an idler 30 loosely mounted on the cross bar l2. The idler 3|! meshes with a second idler 3| carried on a stud 32 mounted in the arm l0. Meshing with the idler 3! is a gear 33 loosely mounted on the cross bar 13 and carrying a cam 34. The groove of this cam engages with a roller 35 on a block 36 rigidly mounted on the rock shaft 9. The rotary movement of the oiling roll is thus communicated through the gear train to the cam which as it cooperates with a fixed roller must itself move,'imparting to the frame of the attachment a limited reciprocating movement in the direction of the length of the corrugating roll.

In the operation of my device the oiling roll is held in mesh with the fiuting roll by its own weight as the frame is free to rotate on the axis of the rock shaft 9. The oil-saturated felt of the center parts 20 of the oiling elements are thus brought into intimate contact with the periphery of the fluted roll to effectively lubricate its surface. At the same time the reciprocating motion of the oiling roll not only polishes the surface of the corrugating roll but causes any foreign matter adhering to it to collect in the peripheral grooves between the individual oiling elements. One end of the shaft 8 may be provided with a handle 31 by means of which the shaft may be rocked on its axis to lift the oiling roll from the corrugating roll to permit the removal of debris from the peripheral grooves of the former or to give access to the surface of the latter.
