ADHESIVE-APPLYING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 746,657, dated December 15, 1903.
Application filed Novemberlt, 1902. Serial No. 131,112. (No model.)
To aZZ whom it may concern.-
Be it known that I, JOHN C. F. BALZE, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Adhesive-Applying Mechanisms, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
This invention relates to certain improvements in paste-applying devices.
In applying paste to moving material running at high speedsas, forinstance, the webs of paper in printing-machines, to which paste is applied on therun--it is necessary that the paste-applying blade or other device run at a high speed. In the constructions generally employed for the purpose of pasting webs the blade or other pasting device takes its adhesive from a fountain and delivers it to the web. The adhesive in these constructions is delivered, as is customary, by a fountain-roll which runsin a supply of adhesive. It is of course apparent that the speed of the applying device should' be substantially equal to that of the web at the time it applies the adhesive thereto, and it is also apparent that the speed of the applying device should be the same as or substantially the same as the speed of the fountain-roll at the time it takes its adhesive therefrom. It is impracticable, however, to run the fountain-roll at the same speed as'the web, because the adhesive will fly off it by centrifugal force, so that the machinery and frequently the web becomes gummed and soiled. To, avoid this difficulty, it has been proposed to run the fountain-roll at a slower speed than the web and operate the paste-applying blade by mechanism of such a character that the blade will move at the speed of the web at the timeit is applying the adhesive to the web and will move at the speedof the fountain-rollat the time it is taking adhesive from said roll. The
mechanism, however, which it has been proanism by which adhesive can be taken from the fountain-roll running at one speed and applied to a web or other material mpving at a different speed.
With this and other objects in view the .Fig. 2 is a detail sectional view. Fig. 3 is a plan view.
Referring to the drawings, which illustrate one concrete embodiment of the invention, 1 indicates the frame of a printing-machine, which may be of any usual construction and configuration. The machine selected to illustrate the invention prints on a Web 2, which is printed and perfected by the usual couples indicated at 3 and 4, 5 and 6. After being printed the web passes over a guide 7 and after being operated upon by the pasting device, to be hereinafter described, is or may be subjected to the action of a slit-tor or slitters 8, which cooperate, as usual, with a driven roll, said roll in the present instance being driven by means of a bevel-gear 9, which receives its motion from another bevelgear 10, mounted on the end of a vertical shaft 11. This vertical shaft 11 is provided with a bevel-gear 12, which meshes with another bevel-gear 13, driven from the gearing by which the usual collecting and folding mechanism 14 is operated. This mechanism is driven in turn from a counter-shaft 16 by means ofatrain of gears. (Indicated by dotted lines at 17 in Fig. 1.)
The adhesive-applying mechanism may be located at any desired point in the machine and may be varied widely in its details of construction. carrier is cylindrical in outline and comprises two heads 35, mounted on a shaft 36, suitably journaledin the fra-me,said shaft being driven in any suitable inannera's, for instance, by a gear 37, which is in turn driven by gearing In the construction shown the from the slitting mechanism. The paste-applying device may be varied in form and construction. As shown, a plurality of such devices is employed, each of said devices comprising a blade 38, mounted on a shaft 39. The shafts 39 are journaled in the heads 35 of the cylinder.
The paste may be supplied from any suitable source. As shown, there is provided a fountain 25, in which runs the usual fountainroll 26, said roll being provided with a gear 28, which meshes with a gear 29, mounted on the shaft 86. In the construction shown the carrier runs at a less speed than the speed of the web, and the fountain-roll is driven at a speed which is less than the speed of the carrier.
It is of course desirable that at the time when the paste-applying blades touch the fountain-roll they move at the speed of the roll, and it is also desirable that when they apply the paste to the web they move at the speed of the web. In order to vary the speed, so that the blades may move as before stated, the blades are given a movement which is independent of the movement of the carrier. This independent movement of the blades may be produced by any desired mechanism; but when the blades are mounted on shafts, as in the construction shown, it will preferably be efiected by rocking the shafts. To this end each of the'shafts 39 is provided with a crank-arm 40, said arms being provided with the usual cam-rolls 41. A stationary cam 42 is provided, said cam being secured to the frame in any suitable manner, and the cam-rolls of the crank-arms 4O engage the groove formed in this cam. This groove is so shaped that at the time when the carrier in its rotation brings a blade in contact with the paste-fountain roll 26 the shaft is rocked to give the blade a movement in a direction opposite to the movement of the carrier, this movement being of sufficient extent, so that the speed of the blade is brought down to the surface speed of the fountain-roll. After the blade has touched the fountain-roll the cam rocks the shaft in the opposite direction, its contour being such that at the time when the blade touches the Web to apply its line of paste thereto the blade is moving in the direction of the carrier, but independently of the carrier, so that its speed is brought up to the speed of the web.
The details of the'construction by which the invention is carried into effect may be varied within wide limits. While the invention is particularly adapted for use with printing machinery, it may be used in other relations. The invention is not, therefore, to be limited to the specific details of construction hereinbefore set forth or to the specific use described.
What is claimed is 1. In a pasting device, a moving carrier, a paste-applying device mounted in the carrier,
to vary its speed in taking and delivering the paste, substantially as described.
3. In a pasting device, the combination with a paste-supply, of means for supporting and moving a web in proximity thereto, a rotating carrier, a pasting-blade mounted in the carrier, and means for giving the blade movements independent of the movementsof the carrier in order to vary its speed in taking and delivering the paste, substantially as described.
4. In a pasting device, the combination with a paste-supply, of means for supporting and moving a web in proximity thereto, a rotating carrier, a paste-applying blade mounted in the carrier, means for giving the blade a movement in a direction opposite to the movement of the carrier at the time it takes the paste and for giving it a movement in the direction of movement of the carrier at the time it delivers the paste to the web, said means being independent of the movements of the carrier, substantially as described.
5. In a pasting device, the combination with a paste-supply, of means for supporting and moving a web in proximity thereto, a 1'0- tating carrier moving at a substantially constant speed, a paste-applying blade mounted in the carrier, means for giving the blade a movement in a direction opposite to the movement of the carrier at the time it takes the paste and for giving it a movement in the direction of movement of the carrier at the time it delivers the paste to the web, said means being independent of the movements of the carrier, substantially as described.
