PASTING AND FOLDING MACHINE FOR BOX-BLANKS.
SPECIFICATION forming part of Letters Patent No. 715,620, dated December 9, 1902.
i Application filed March 25, 1902.. Serial No. 99,846. (No model.)
T0 a/ZZ whom, it' may concern:
Be it known that I, EDWIN G. STAUDE, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvernents in Pasting and Folding Machines for Box-Blanks, of which the following is a specification.
The invention relates to machines for making paper or pasteboard boxes adapted par.
ticnlarly for containing cereal foods.
The object of the invention is to provide a machine wherein very thin and cheap brittle paper can be cut, pasted, and folded with neatness and despatch, which cannot ordinarily be done in pasting-machines as now constructed, owing to the fact that the paper is too thin to be pushed along by the traveling belts and their lugs or is not sufficiently tenacious to permit the partially-severed blanks to be dragged through the several steps of pasting and folding.
Other objects of the invention will appear from the following detailed description.
' inafter described, and particularly pointed out in the claims.
In the accompanying drawings, forming part of this specification, Figure 1 is a plan view ofa box-making machine embodying my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a perspective view of the cutting, pasting, and folding devices removed from the supporting-frame and in section. Fig. 4 is a transversev section showing the position of the folding'devices with respect to the rotating guides or the presserrolls; and Fig. 5 is a detail view of a modification, showing two sets or series of rolls between which the blanks are fed. l
In the drawings, 2 represents a suitable frame having bearing-blocks 3 at one end` for the upper and lower cutting-rolls -1 and 5, the
former being adjustable toward or from the latter by means Vof the set-screws 6. The
shafts for said rolls project beyond their bearings on each side of the machine, and the upper roll is provided with a gear 7, meshing with a similargear on the shaft of the lower roll, and on the' opposite end of the lower roll I provide a sprocket' 9,-connectedwith a smaller sprocket 10 on a shaft 11 near the opposite end of the machine. The shaft 11 carries a roll 12, and a similar roll 18 is provided near the cutting-rolls, and upon said rolls 12 and 13 I arrange an endless conveyer-belt 14,
that is adapted to travel over a flat table or bed 15, provided on said frame and extendinglengthwise thereof. The cutting-rolls are provided in their peripheries with the usual scoring means (not shown) and transverse knives 1o, which score and cut the blanks where they are to be folded, and longitudinal knives 17 to sever the blanks one from another as the sheet passes between the rolls.
Upon thetable 15 near the cutting-rolls I provide an arched frame or bracket 18, providednear its ends with vertically-slidable rods 19, that are adjusted by means of nuts 20, and are provided beneath said bracket with springs 21, which engage the under side of the bracket and horizontal bars'22, carried by said rods, and normally hold said bars a'nd rods in ltheir depressed position. The bars 22 run parallel with the conveyer-belt and table and are provided with a series of idle-wheels 23, between which and the con- Veyer-belt the box-blanks are fed from the cutting-rolls and by which said blanks are held in a flatwise carrying position upon said belt. A paste-reservoir 24 is provided on one side of said table, and achain 25, operating over wheels 26 and 27, lifts the paste to the surface of ythe table, and as the edges of the blanks pass between the wheel 27 and the paster wheel ordevice 28 a sufficient quantity of paste is smeared along the edge of the blank to securethe overlapping edges together when the blanks are folded. This paste-reservoir device has been described in detail in my previous pending application, -and hence needs no further illustration or description herein. Near the middle jof the table I provide a second bracket 29, corresponding to the one described, except that it is provided with a single wheel-supporting bar 30, arranged, preferably, along the central line of the table and carrying a series of wheels corresponding to those heretofore de- IOO scribed and adapted to engage the blanks near the middle line thereof. These wheels serve to hold down the middle of the blank while the sides are being raised by the action of the folders, the first set of wheels, heretofore described, being designed to hold both sides of the blanks on the belt while the edges are being smeared with paste and when the sides of the blanks are first engaged by the folder-arms.
Near the discharge end of the machine I provide a third bracket 31, carrying two parallel bars 32 near its ends and the edges of the belt, said bars being supported in a manner corresponding to those heretofore described and carrying a series of idle wheels which serve to engage the sides of the blank after they have been folded and turned in over the middle portion and press them down to bring the edge that is smeared with paste into contact with the one that it overlaps. During the passage of the blanks over the table they are held between the idle wheels and the belt and carried rapidly along through the steps of pasting and folding. The blanks will be entirely severed one from the other, and being held down upon the belt and table by the yieldingly-carried wheels above will be prevented from twisting or curling or becoming bent or broken through their extremely ilexible or brittle character.
The folding means which I prefer to employ in connection with this machine consists of arms 33, that are secured to the bracket 3l and extend back beneath the other brackets in position to engage the blanks as they leave the cutting-rolls. The receiving ends of the folders lie close to the table to pass beneath the approaching ends of the blanks, and the folders are then gradually curved upward and inward to a point above the middle portion of the carrier-belt. Until reaching a point near the discharge end of the bar 30 the folders run substantially parallel with each other to their points of connection on the bracket 3l. The various curves and bends in these folderarms serve to make the necessary folds in the blanks to produce the complete box.
In Fig. 3 the sides of the box are represented as being turned up to a vertical position by the folder-arms, While in Fig. 4 the sides are shown vertical and about to be turned over one upon the other. Near the discharge side of the machine I provide shafts 34, provided with gears 35, driven from similar gears 36 on a shaft 37, and said shafts 34 are provided with spiral conveyers 38, that engage the edges of the blanks as they are discharged from between the conveyer-belt and wheels and advance them on edge Within a conveyer box or casing 39, where they are packed ready for use.
In Fig. 5 Ihave shown a construction wherein the conveyer-belt is dispensed With, and I have provided two sets or series of Wheels or rolls 40 and 4l, between which the blanks are fed and advanced. Either one or both sets of these wheels are driven by suitable means. These wheels will serve to advance the blanks quite as rapidly as the mechanism heretofore described and in some cases may be preferable to the conveyer-belt. I do not wish to confine myself, however, to the particular adaptation shown of the Wheel or roll feeding means, as the same is capable of various modifications, the essential feature of the invention being the means for advancing the blanks that is adapted to receive either those of very thin and iiexible or cheap brittle material or that which is comparatively sti in character and advancing the same through the successive steps of forming the box with equal facility.
I claim as my inventionl. The combination, with the cutting and scoring rolls, of an endless carrier-belt whereon the cut and scored blanks are delivered, curved folder-arms provided above said belt, the intermediate or middle portions of said arms being inwardly curved toward the middle of said belt and adapted to fold the raised sides of the blanks in over the middle p0rtions thereof, means near the receiving ends of said folders for holding the blanks upon said belt during the operation of raising and turning in their edges, a pasting device, and idle wheels provided above the middle of said belt between the inwardly-curved sections of said folders to press the blanks down upon said belt, and said wheels extending to a point opposite the termination of said inwardly-curved sections to insure the rapid continuous feed of the blanks while their sides are being folded.
