MACHINE FOR MAKING CORRUGATED PAPER-BOARD.
Specification of Letters Patent.
Application filed April 24, 1918. Serial No. 230,413.
To all whom it may concern.
Be it known that I, EDGAR M. HAWKINS, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New .York, have invented certain new and useful Improvements in Machines for Making Corrugated Paper- Board, of which the following is a specification.
This invention relates to machines for making lined corrugated board, such, for'example, as disclosed in my pending application, Serial No.- 69,093.
.The machine of that application comprises a pair of corrugating rolls which corrugate the filler and transfer it to a rotary drum having corrugations adapted to receive and hold the corrugations'formed on the filler. While the corrugated filler is being so carried on the surface of the drum, it has applied thereto a coat of adhesive by means of an adhesive-applying device capable of applying the adhesive to the ridges of the corrugations. The corrugated filler with its coat of adhesive then has applied thereto a liner or facing which is suitably conducted to the periphery of the drum. The corrugated filler then provided with one liner, travels with the drum for a predetermined distance 'and is removed therefrom by a transfer roll in such manner as to expose the unlined side of the corrugated filler. Adhesive is then applied to the ridges of the corrugations on the unlined side of the filler after which the other or second liner is applied. The filler then lined on both sides is passed over a, heating bed to dry the adhesive and firmly unite the layers.
The arrangement of parts in that mais passed over the heating bed with the last formed joint, that is, the joint between the filler and the last-applied liner, separated from the heating bed by both the corrugated filler and the lower or first-applied liner. This of course does not result in as quick setting of said last formed joint as would result if that joint were next the heating bed when the lined filler is passed thereover, and as it is desirable that the joint should be set as quickly as possible, it has been one of the objects of my present invention to provide for the accomplishment of this, which is done in the present case by locating the heating bed at the upper side of the path of the lined board and next to the last formed joint.
In the former construction, wherein the lined filler passed over the heating bed, said lined filler, in the event of the machine bemg stopped for any reason, was liable to become burned. In the present case, where the heating bedv is above the lined filler, I am enabled to avoid the possibility of such burning by the provision of means for ef- Patented Jan. 6, 1920.
fecting the quick lowering of the support over which the lined filler passes, whereby, upon the stopping of the machine, said sup-' port may be lowered and thereby permit of the lined filler sagging or dropplng away from contact with the heating bed. For the ready and convenient manipulation of said support manually operable raising and lowering means therefor are preferably employed.
In addition to the above mentioned features, there are other novel features which will appear as the specification proceeds.
The invention is illustrated in its preferred form in the accompanying drawings, in which Figure 1, is a more or lessdiagrammatic side elevation of the machine showing the general arrangement of the various parts thereof and the paths of travel taken by the filler and the two liners;
Fig. 2, is a top plan of the same;
Fig. 3, is an enlarged central longitudinal and vertical section through the main front end of the machine which is that part embodying my present invention;
Fig. 4,-is a vertical cross section taken on the line 4-4 of Fig. 3;
F ig. 5, is detail plan showing part of the noted generally by the reference character i. i i i A. 'The filler 1H corrugated by means of these rolls and then transferred to the. corrugated heating. drum B. which carries the corrugated tiller to a. transfer roll C by means of which the corrugated filler is removed from the drum.
Just after the corrugated filler has been gripped by the drum ll. the adhesive-applying mechanism. denoted generally by the reference character D. applies adhesive to the ridges of thecorrugations. The corrugated board so coated with the adhesive then has applied thereto the bottom liner 1) which is conducted to the periphery of the drum B from asupply roll l/over a preheating device, denoted generally by the reference character E. into contact-with the adhesive coated corrugatedtiller adheres thereto and is carried withthe corrugated filler to the transfer roll C wherethefiller. lined on one side, is-
removed from thedrum and reversed so that theunlined side of the corrugated filler is exposed to the adhesive-applying mechaparts.
nism indicatcd at F. In this manner. the ridges" ofthe corrugations on the unlined side of the filler have applied thereto a coatingflof adhesive so that thesecoml or top liner will adhere thereto. This second liner c is fed from a supply roll 0 over a preheating device G similar to the preheating device E for the bottom liner. A pressure roller H bringsthe top liner into proper relation with the adhesive coated corrugations of the filler, thus causing the top liner to adhere to the corrugated filler. A set of pullrolls 1, between which the completed materialpasses, draws the lined corrugated fillelypas't a heating bed, denoted generally by J against which it is yieldingly held by a supportingbed, J.
The above description gives a broad idea, of the general arrangement and ope tlon" the oflthe main parts of the machiii'; an( following.idescriptionr'will set forth more in detailthe construction of certain of those The drum B is rotatably mounted in the mainstandards i and 20f themachine (Fig. 4),.andfis provided over its entire surface with a plurality .ofycorrugations running longitudinallyof the drum. The corrugating mechanism A for corrugating the filler y and from which the filler is transferred to said drum B, comprises a pair of corrugating rolls 4 and 5, each provided over its entirefsurface with teeth mcorrugations running longitudinally oftherolls. The teeth of these two rolls mesh so that the filler passing between them is corrugated in well know n nanner, .The teethiof the roll'l also meshi with the teethion the drum B. sothat thecorrugations of the filler board. are .-di-
rectly' positioned in corrugations on the drum when transferred to the latter. The
The bottom liner so brought ter in turn applying the adhesive to the r ridges ofthe corrugations of the filler on the drum B. i
The bottom liner 1) is carried from its sup ply roll-under a guide roll 55, then up over the periphery of the heating pipe E. then ('lownwardly under a pressure roll 56. and
from thence upwardly to.a roll 46 just be low the adheslve-applylng mechanism D,
over which it passes into'contact with the adhesive coated filler on the surface of the drum.
The corrugated filler, now supplied with the.bottoinliner, is carried withthedrum until the transfer roll is reached. The corrugatedfiller and bottom liner then pass around thistransfer roll with the bottom liner adjacent to the surface of the roll. The unlined side of the filler is therefore exposed in passing around the transfer roll (I, thus giving anopportlmity of applying adhesive to the corrugations at the unlined side of the filler. This is done by [means of the adhesiye a))lvin mechanism F. which is similar in all respects to the adhesive-applying mechanism D for applying adhesive to the opposite side of the filler.
The top liner cis applied to the corrugated The top lineris conthe periphery of the preheating device G, from which it-passes under a pressure roll 81 to the filler on the transfer roll C.
The construction and operation of the machine as thus far described, except the supporting andheating beds J and J hereinbefore briefly referred to, is substantially the same as that of the machine of my aforesaid pending application and therefore does not here require further detalled description. The corrugated filler, now llned on both .filler as the latter reaches the u'ppeFpai-tof the transfer'roll C. ducted to this point from the supply roll 0, ""over an idler roll 79, to. and under an adjustable tension roll SOQand from thence over sides as described,"passesfrom the transfer roll C between the supporting bed J and the heating-bed J. The heating bed J comprises severa] horizontally alined' steam chests 100 which are supported from the upper frame-work.101 by suitable fastening.
means, such'asthe bolts 102. Steam may be suppl ed to these chests in any usual or suit able manner. a a a H The supporting bed J above referred to comprises a frame carrying a plurality of pressure devices, here shown in the form of upstanding brushes, whichact to yieldingly but firmly hold the lined filler up against the heating bed as it is drawn thereover by the pull rolls I. In this manner, the lined filler is brought into intimate contact with the heating bed with the last formed joint, that is, the one between the filler and the upper liner, in position next to said heating bed, whereby a quick setting of said joint will be effected.
The frame of this bed J comprises longitudinal side members 105 and connecting cross members 106, both in the form of angle irons as shown. Extending transversely across this frame are a series of bars 107 carrying brushes 108 and mounted at their ends in holding brackets 109 which are detachably connected to the side members 105 by suitable fastening means, such as the clamping screws 110 (see Figs. 4 and 7). It will be noted that the brushes are set to have a rearward inclination so that the lined filler will slide freely over them when being drawn through the machine. At the front end of this brush carrying frame is a transverse bar 111 to which is secured a sheet of canvas or other flexible material 112 passing rearwardly over the tops of the brushes. This canvas, intervening between the brushes and the lined filler, serves to more evenly distribute the pressure of the brushes against the surface of the lined filler in the passage of the latter thereo-ver.
The supporting bedjust described is supported vertically by a plurality of coiled springs 114, here shown as four in number and arranged with two at each side of the frame. These springs are interposed between the under side of the cross members 106 of the frame and stationary brackets 115 on the main framework, and arepositioned about guide spindles 116 which are carried by .the brackets 115 with their upper ends extending freelythrough openings in the frame members 106. In this way the supporting bed may be easily raised and lowered with respect to'the heating bed, as it is substantially balanced by .the
springs 114, and it will be guided in-its vertical movements by the guide spindles 116.
As a means for raising and lowerin the supporting bed J with respect to the eating bed, I provide two rock shafts 117 which extend transversely of the machine below said supporting bed and are journaledin} suitable bearings 118 on the frame work.
These rock shafts are provided adjacent their opposite ends with shortcrank arms 119 which connect through the medium of pivoted links 120 with the opposite sides of" the supporting bed, whereby, upon the rocking of the shafts, a raising and lowering of the connected bed will be effected. In order as here shown being formed with an opening 124 near its handle end to receive therethrough a latch bar 125 which is pivoted at itslower end to a stationary bracket 126 secured'on the floor or other support. A latch connection between the lever and this bar is made by means of a latch pin 127 which is carried by the lever and adapted to engage the bar at different points in the length thereof through openings 128 therein (see Figs. 1; and 6), the said pinbeing operated to engage and disengage the bar 125 by means of a connecting lever-handle 129 which is pivoted to the lever 123 at 130 and serves as a handle for said lever. The arrangement of this lever handle is such that the operator, grasping the same, may operate it to first disengage the pin 127 from the bar 125, and then, while still grasping the handle, swing the lever 123 in a direction to effect the desired raising or lowering of the mit the supported paperboard dropping or saggmg away fromthe heating bed and thereby prevent it from becoming. burned.
It will be clear that this may be readily and conveniently accomplished by the. construction illustrated and described. I 'Although my present invention has been set forth in its preferred form, it is obvious that numerous modifications and changes maybe made in the details of construccompanyin claims.
