signor to I.* Miller"& Sons, Inc., Long Island City, N. Y., a corporation of New: York Application April 12, 1937, Serial 'No. 136,355

* 2 Claims. (01. 91-43) This invention relates to means, forapplying adhesives to lengths of material, for example, bindings, tapes, etc. or other strips or sheets-of indefinite lengths.

While the adhesive-applying means of the:

the inner strip, which is usually composed'of fabric. In the manufacture. .of such bindings, especially whenrubber cement is used as the adhesive, difiiculty is experienced in applying the adhesive to the inner surfaceof the strip material without soiling the outer surface .of such material with the adhesive. One object of the present invention, therefore, is to provide means for obviating this difficulty, and for that purpose to facilitate the application .of adhesive to one surface of the strip, or to a predetermined p'or tion of said surface without coming in contact with the outer surface of said strip.

As the strip materials vary in width depending, among other things, upon the width of the bindings to be produced it is desirableto provide means for regulating the flowv of cement toIthe strip material in accordance with the. width thereof. Furthermore, in some cases, it is necessary to confine the application of the cement to a portion only of the width .of the strip as for example to a marginal edge portion only of the strip, leaving the remaining, portion of the width of the strip uncoated. This can be readily accomplished by the regulating means hereinbefore referred to. I A further object of the inventionis .to provide means for applying, cementto and evenly distributing the same over the surfacel of. the

material.v Another object of the invention is generally to provide an adhesive-applying means which is simple in construction and designed to facilitate the application of cement to strip material so that large quantities .of such material may be .coated with cement in an efficient manner whereby the time and labor required for that purpose may be substantially reduced.

The above objects of the invention and other objects which might hereinafter appear .willbe fully understood from the following description considered with reference to the accompanying drawings.

In the drawings: H i Fig. 1 is a perspective view of the adhesiveapplying means, in accordance-with .the preferred embodiment of the invention;

Fig. 2 is a side elevation view,on a larger scale,

of the adhesive-applying means shown in Fig. 1;

Fig. 3 is a transversesectional view on th line -33 of Fig. 2;

Fig. 4 is a transverse sectional view on the line 4-4 of Fig. 2; v

Fig. .5 is a detail plan, view.

Referring more particularly to the drawings, the adhesive-applying means comprises an ad hesive applicator-container 10 connected toan adhesive supply container l2 by a pipe 14 provided withan adjustable valvejl'd for regulating the flow of adhesive from saidsupply container 12 to said applicator-container ill. An indicator,

comprising a stationary dial It and a pointer I1 movable with the valve stem, is provided to facilir tate adjustment of the valve for the desired flow of adhesive to container III.

which is preferably made of metal; has a bottom and'a top wall 26. All-of said iwalls'ar'e assembled and secured together in a manner to de-' As here shown, the ,applicator container Ill,

, 20 18, side walls 20, a front wall 22, a rear wall 24,

fine a cement chamber 28 to which .the in 16$s of air is substantially eliminated sothat the cement within said chamber maybe maintained in proper condition forapplicationto the strip material Access of the vided through an opening in theform of a relatively narrow slot 30 formed in thetop wall 26 and extending longitudinally thereof, the end of the slot beingindicated at 30a and 30bin Fig.

2. The lengthof said slot is determinedby the 7 maximum width .of the material whichthe present adhesive-applying means is designed to treat.

The-effective length of said slot, however, may

be .varied or adjusted in accordance with the present invention, and for that purpose, there is provideda valve block.32 slidably mounted on cement to the material ispromovable over. said slot for regulating the length of the opening. Said block 32 is adjustedlongitudinally by means of ascrew 36 which has a screw-threaded. engagement with said block whereby rotation ofsaid screw in eitherdirection by manipulation of the screw head 36zis efiec- T tive to move said valve block longitudinally of slot 30 for increasing and decreasing the-length thereof. Said-screw 34' constituting the valve block adjusting means is mounted for rotation in the upwardly projecting portion 38 of wall 22,

the.:upper surface of wall 26 overslot- 30 and '4 the adhesive will flow by gravity from container IE to container It). If desired, however, said adhesive may be supplied to container it! under fluid or other pressure instead'of, or in addition to gravity pressure. When the apparatus is in use, the chamber 28 is kept filled, there being a regulated flow of adhesive into said chamber under the control of valve [5 and out of said chamber in contact with the material to which it is applied. Thus, ordinarily, for the same class of work, the valve I5 will be opened more or less as the opening through slot 30 is increased or decreased, respectively.

A frame $6 is mounted on top wall 26. Said frame is substantially U shaped, having longitudinally extending side portions 42 and 44 and an end portion 56. Said side portions 42 and 44 are disposed at opposite sides of valve block 32 in engagement with the latter, constituting guideways therefor. Metal strips 48 are secured to said side portions '42 and 44 by means of screws Ell in engagement with the upper surface of valve block 32, thus holding the latter in engagement with the top wall 26.

, c For applying cement to the strip material, the

latter is fed transversely of the applicator container In over the opening 30 therein. A guide passage for the strip material is provided by a groove 54 formed in the side portions 42 and 44 of frame 45!. As the strip material is moved across opening 30, it is pressed firmly against top wall 26 by resilient means here shown as a spring 56. Saidspringis fastened at one end 58 thereof between the top surface of frame portion 54 and a releasable retaining member 66.

Said spring retaining member is pivoted at one end 62 thereof tothe frame portion 44 and is movable from the spring retaining position shown in Fig, 1. may be held releasably in spring retaining posishown in Fig. 2 to the spring releasing position Said spring retaining member tion bya pivoted latch 54 fastened to the top of end portiondfi of frame 40.

As best shown in Fig. 3, the spring 56 is U-shaped and has an intermediate fiat horizontally extendingleg portion 66 which bears on the upper surface of the strip S, and a reiiexed horizontally disposed and upwardly spaced or leg portion ,68 which is engaged by the end of a screw it, which is adjustable for regulating the pressure of the spring on strip S. Said screw H1 is threaded through an opening in a bracket--72 and may be held in adjusted position by a holding nut 74 which releasably engages said bracket. Bracket 72 is mounted to the top wall 26 of applicator container l0 and is adjustable longitudinally of said wall. For that purpose the wall engaging portion iii of bracket I2 is provided with a slot 18 and is engaged in said slot by a holding screw 80 threaded into the top wall 26.

The manner of using the adhesive-applying means described above is more or less obvious from the above description. The valve block 32 is adjusted to provide an efiective opening through the slot 30 of a length depending upon the width of strip material or upon the width of sive.

of pressure on the spring, depending upon the thickness of the strip material and the quantity of adhesive to be applied thereto. With the parts adjusted the strip material is then moved over'the opening 30 and beneath the spring 56 which bears thereon. Thus, the adhesive is applied continuously and uniformly to the surface of-the strip or to a portion of said surface, and the adhesive is prevented from contacting the outer surface of the strip or any surface portion of the strip beyond the area of slot 30.

Thus, it is seen that the construction herein shown and described is well adapted to accomplish the several objects of the present inven-- tion. It will be understood, however, that the invention may be embodied otherwise than as here shown, and that certain changes in the construction and arrangement of parts of the present embodiment may likewise be made without departing from the present invention. Therefore, I do not wish to be limited precisely to the present disclosure except as may be required by the appended claims considered with reference to theprior art.

What I claim and desire to secure by Letters Patent is:

1. Adhesive-applying means comprising acontainer for the adhesive, said container having a wall provided with an elongated slot constituting an outlet opening for the passage of adhesive from said container, a member movable on said wall over said slot longitudinally thereof for adjusting the length of the slot opening, and means for guiding a length of strip material for movement over said wall and transversely of the length of said slot and over the-open part thereof for coating the adjacent surface of said strip material with adhesive during the movement of said strip material across said slot, said slotopening adjusting member having a surface part extending transversely of said slot and constituting a part of said strip-guiding means, and spring means to press said strip against said wall at both longitudinally extending sides of said slot during the movement of said strip material thereacross.
