WIACHHNE FOR STHIPPNG LANKS FOR PAPER BOXES.. y
Patented aan. 3o, 1906.
Application filed NOVBmbel 17, 1904. Serial No. 233,148.
ATo 'a/ZZ whom it may concern:
Be .it known that I, LYNDON C. PALMER, a
` citizen of the United States, residing at Buffalo, in the county of Erie and State of New I l York, have invented certain new and useful Improvements in Machines for Stripping Blanks for Paper Boxes, of which the follow# ing is aspecification.
My invention relates to machines for strip- `ping blanks for paper boxes, whereby the lap or marginal portion of the blank is reduced in thickness.
In forming square boxes the cardboard blanks yare scored lengthwise at points forming the vertical 'edges of the box, and the lap or marginal portion overlaps one of the sides and is glued thereto. the blank as now done is objectionable not only because it is unsightlywhen the regular thickness of cardboard is overlapped, but
`also for the reason that two thick layers are not as quickly and as securely glued to! ether as one thin layer glued to a thick layer. y stripping the lap of the blank to reduce the thickness the lap can-be quickly and con-` veniently glued without resortingl to pressure to hold the two layers together, whereas ingluin two thick layers together the folded blan must be held in a press for some time, thus consuming valuable time and reuiring considerable. labor, with the result 'A t at an unsightly and less rigid box is` conl blank .is fed to the stripping-knife with thev structed than by themethodpfstripping the cardboard.
` The object of my invention is to produce a machine which will strip the lap or marginal `portion of a cardboard blank as it is fed through the same for the purpose of reducing the thickness of said marginal portion.
Other objects are to construct a machine of this type which can be adjusted to feed the lap accurately to the stripping knife irrespective of the width of the lap or the width of the blank, to `provide a simple, effective, and durable machine of fewl parts, and to provide flexing and feeding rolls whereby the aper separated at thelap from the, scoreine outward.
With these and other objects in view the vinvention consists in a series of feed-rolls, means for flexing the blank at the lap or marginal portion to separate the layers of paper This overlapping of from the score-line outward, and means for stripping the paper'to reduce the thickness of the same at the lap.
It also consists in the construction, combination, and arrangement of parts to be hereinafter described, and particularly pointed out in the appended claims. L
In the drawings, Figure 1 is a side elevation of my stripping-machine. Fig2 is a top plan view of the same. Fig. 3 is a longi-l tudinal section taken on line 3 3, Fig. 2. Fig. 4 is an enlarged transverse section taken on line 4 4, Fig. 2. Fig. 5 is an enlarged transverse section taken on line 5 5, Fig. 2. Fig. 6 is an enlarged transverse section t'aken on line 6 6, Fig. 2. Fig. 7 is a sectional perspective view of a Vportion of a cardboard blank, showing the score-line dividing the lap from the remainder of the blank. Fig. 8
4is a similar view showing the lap flexed 'after several figures.

'of a horlzontal securing portion s, bolted to-v are geared to ether by 'gears N, the lower one of which is he d in mesh with an idler ln, driven by the gear K on the lower` roll ofthe lsecondi' mentioned pair of feed and exing rolls. Thus the ro ls are all operative connected with the power-shaft to cause t e blanks to The upper rollsof the feed and flexing rolls are of equal length, and each is provided with an annular groove O near one end to form a gage edge o, the cardboards being fed to the rolls with the score-line in registration with said a e edge. Each upper feed-roll is also prov-i e with a ilexin -rim P, which is of reater diameter than t e body of the roll. he lower roll of the first-mentioned pair of feed and flexing rolls extends slightly beyond the` age edge of the upper rolls, whi e the lower ro l 'of the second-mentioned pair of feed and exing rolls is somewhat longer than the lower roll of the first-mentioned pair and extends beyond the gage edge of the upper rolls to' a greaterextent than does the ower roll of the iirst-'men- R designates a platform located between the feed-rolls and delivery-rolls, over which the cardboard blanks pass as they leave the feed-rolls.

In operating the machine the several rolls are revolved in a direction to feed the cardboard blanks between the rolls to thestripping-lmife. and delivery-rolls, the latter gripping the blanks and deliverin the same'to a suitable platform or receptac e, from which they ma be carried to a glun -machine for gluing t e lap portion, o r, 'v desired, the

The blanks are fed Avinto the machine with the scored side face up, and as they pass -between the first pairof feed and flexing rolls the flexing-riml of the upper roll forces down that portion of the la extending beyond the edge of the lower ro l, which causes the paper layers forming the board to separate from the score-line out toward the edge a certain distance, the thickness of the paper being thus separated depending on the de th of the score made inthe blank. If desire the iiexed lap with a portion thereof thus separated from the blank may be presented to the strip ingknife without passin through a secon pair of iiexing-rolls; but have obtained best rc- Sults by passing them between a second pair of flexing-rolls, which serve to further separate the layers of the board, rendering it comparatively easy to strip the board as it comes 1n contact with the strlpping-knifc. By separating the paper as'above described throug out the length of the lap assurance is had that the strip will be evenly cut throughout its length. When the stripped cardboard is glued, it is foldedat the score-lines to form a tube, with the stripped lap glued against oneA of the sides. Ordinarily the cardboard is of sufHcient length to form a number of boxes and after being glued and folded is cut to the desired lengths to form the sides of the box.
This invention is susceptible -to many changes inthe form, arrangement, and construction of-parts without departing from the sco e thereof, and I do not Wish to linut mysel to the embodiment of my invention herein disclosed.
Having thus described my invention, what I claim is- 1. In a machine for stripping cardboard blanks or the like, the combination with a suitable frame, of a feeding device for feeding the blanks forward, and a stripping device in the path of the blank for reducing the thick.- ness of the mar inal portion of the latter so that the reduced marginal portion is of even thickness throughout.
