Patented Mar. 8, 1932 UNITED STATES PATENT OFFICE GEORGE W. SWIFT, 33., OF BORDENTOWN, NEW JERSEY, ASSIGNOR TO GEORGE W. SWIFT JR, INC., 01 BORDEN TOWN, NEW JERSEY, A CORPORATION OF NEW JERSEY MACHINE AND PROCESS FOR MAKING OORBUGATED BOARD Application filed July 28, 1981.
This invention relates to machines for making corrugated paper board and more especially to that'type of said machines in which a pair of intermeshing paper-corrugating rolls operate upon a web for corrugating it, after which said corrugated web while it remains in one of the corrugating rolls, has its tips provided with adhesive preparatory to applying a .liner web thereto under the pressure roll between which and the corrugating roll. the corrugated web and liner are passed. For this purpose, the corrugating rolls andpressure roll are usually mounted on rotary axes arranged in a common vertical plane while an adhesive fountain roll is usually arranged to apply adhesive to the tips of the corrugated web as it moves downwardly around the lower corrugated roll on its way' to have the liner web applied thereto under the pressure of saidpressure roll.
Up until ten-to fifteen years ago, it was not uncommon to operate machines for making corrugated boards at a linear speed of from 60 to 70 feet per minute. At the present time, machines of this character may be operated at a speed running as high as 300 linear feet per minute. The feeding mechanism of machines of this nature usually consists of a plain drum which is pressed against and rotated by the lower corrugating roll. While this device is sufficient for applying a liner sheet to a corrugated web at a low velocity of movement, it is not suitable for high velocities. Thus, due to the inter-tooth spaces of the corrugating roll, the feeding action between it and a plain pressure roll, is nonuniform. For example, in an 8" corrugating roll operating tightly against the peripheral surface of a plain drum or pressure roll, the circular pitch of'the flutes in the former may be in the neighborhood of three-tenths of an inch. By actual measurement, this may produce a variation of about .0001 inch in the effective radius of the corrugated roll so that the linear feed of the paper varies considera- As the speed of the machine is increased, the effects of this variation as well as of the tension on the paper web, accompanied by an increased vibration of the several parts,
Serial No. 552,880.
produces an increasing tendency of the paper to pull back. In consequence, the flutes of the corrugated web are apt to be'deformed so that after one liner sheet has been applied to the corrugated web, said flutes will vary materially in depth. As a result, when a second liner sheet is applied to the other face of the corrugated web, the relatively higher flutes in the corrugated Web will operate to hold said second liner sheet away from the lower flutes and thus produces an inferior product.
The primary object of this invention is to provide an improved process and means of improved construction for producing highgrade corrugated board at high linear velocity. Toward the attainment of this purpose, my present invention contemplates the provision of one or more additional feed rolls or drums for cooperating one at a time with one of the corrugating rolls for the purpose of providing a more uniform and a better sustained-feeding action while at the same time prolonging the period of drying under a sustained pressure produced by this feeding action. As an illustrative embodiment of my invention, I have shown on the drawings two plain pressure rolls or drums which operate against a corrugated roll in divergent planes through the rotary axis of the latter, the arrangement being such that the maximum effect between one of the drums and the crown of a tooth of the corrugating roll becomes active in alternate relation to that occurring between the other pressure drum and a tooth of the corrugating roller. By means of this construction, an extra squeeze or impingement is applied to the joined webs and inasmuch as the pressure rolls are spaced around the periphery of the corrugated roll and operate thereon in alternation, it becomes possible to secure a practically continuous feed of the corrugated board at a high velocity, such, for example, as a linear velocity of 300 feet per minute. In effect, with two pressure rolls, the space between the teeth is practically cut in halves, the result being that an tendency of a hold back is prevented. ence, corrugations of uniform depth are produced and the feeding action is made practically uniform, so that when the second liner sheet is applied, the product will be of uniform quality. Furtherlmare, as the double-faced board manufacturing machine constructed in accordance with the underlying principle of this invention;
Figure 2 is an enlarged fragmentary side elevation of the same.
. Referring more particularly to the drawings, a web 1 which passes about a guide roller 2 moves downwardly and ispassed between an upper corrugating roll 3 and a lower corrugating roll 4. The corrugated web as it passes downwardly around the corrugating roll 4, has its tips brought into contact with a silicate-applying roll 5 operating in a bath of silicate 6 within a container 7. Following this application of adhesive, the corrugate web passes downwardly and to the right between the corrugating roll 4 and a pressure roll or drum 8 which presses a liner web 9 against the silicated tips of the corrugated web. Said liner'web is drawn from a mill roll (not shown) and passes upwardly around a guide roller 10 and thence between the pressure roll 8 and the corrugated web. The corrugated web with the liner sheet attached is then caused to ifollowaround the periphery of the lower corrugating roll 4 and between said lower corrugating roll and a second pressure roll 11 which applies an additional squeeze to the joined webs in alternation with that imparted by pressure roll 8, the relative angular disposition of said pressure rolls around the axis of corrugating roll 4 bein quantitatively measured by a mixed fractiona multiple of the circular pitch of the teeth on the corrugating roll 4, It will thus be understood that as the squeezing pressure between the lower corrugating roll 4 and pressure roll 8 cases up on one portion of the single-faced corrugated board, the squeezing'pressure be- 7 tween the pressure roll 11 and said corrugating roll 4 is increasing on another portion thereof, and woe versa. This construction and arrangement of parts has been found to produce a uniform speed to the single-faced corrugated board and to maintain the united webs under uniformpressure as it passes around the corrugated roll from one pressure roll to the other in such a way as to prevent the deformation of the corrugations of the corrugated web due to hold-back of the mill rolls. Thus, if there is but a single pressure roll, and the united webs are drawn tangentially from the cooperating rolls as indicated in dotted lines in Figure 2, whenever the" pressure roll comes opposite to an inter-tooth space, there is a tendency for slippage due to a materially lessened pressure so all of the tips of the corrugated web. In the preferred embodiment of my invention shown on the drawings, I prefer to pass the. corrugated web with one liner aroundthe spaced pressure rolls 11 and 8 in its movement toward the mechanism (not shown) for applying the second liner web.
