MULTIPLE ORIFICE GLUE APPLICATOR Filed Sept. 5, 1965 FIG-'2 42 4a INVENTOR. HAROLD w. HUFFMAN ATTOR N EY S cleaning or adjustment, and simple and United States Patent 3,298,353 MULTIPLE ORIFICE GLUE APPLICATOR Harold W. Hufiman, Hamilton, Ohio, assignor to The Hamilton Tool Company, Hamilton, Ohio, a corporation of Ohio Filed Sept. 3, 1963, Ser. No. 306,224 21 Claims. (Cl. 118-411) The present invention relates to a multiple orifice glue applicator, such as may be employed in applying lines or stripes of liquid glue to one or both faces, at selected 10- cations, of a moving sheet or web.

An object of the invention is to provide a simple yet effective applicator for attachment to a machine such as a collator, for applying lines or stripes or liquid glue to a moving sheet or web.

Another object of the invention is to provide a glue applicator effective to apply stripes or lines of glue to opposite faces of a moving sheet or web, at selected locations thereon.

p to controlling the application of glue stripes upon a web,

as to avoid undesirable soiling and smearing of the handling equipme'nt'with excess glue.

A further object is to provide an applicator of the character mentioned, which is compact, easy to attach and detach from existing web handling equipment for inexpensive to manufacture.

The foregoing and other objects are attained by the means described herein and illustrated in the accompanying drawing, in which:

FIG. 1 is a perspective view of an applicator embodying the present invention.

FIG. 2 is a rear elevational view of the same.

FIG. 3 is a front elevation showing a web passing through the applicator.

FIG. 4 is a rear elevation of FIG. 3.

FIG. 5 is an enlarged cross-sectional view taken on line I 55 of FIG. 3, and showing the applicator attached to a glue supply pipe.

FIG. 6 is a cross-section taken on line 6-6 of FIG. 5. FIG. 7 is a cross-section taken on line 7-7 of FIG. 6, the moving we'b being omitted.

FIG. 8 is an enlarged cross-sectional view taken on line 8-8 of FIG. 7.

In the drawing, W indicates a sheet or web of material such as paper for example, movable continuously in one direction at high speed. It is sometimes necessary or desirable to apply to one or both faces of the web, a stripe or line of liquid glue or the like while the web is in motion, usually at a high linear speed. In some instances, the line or stripe of material may desirably be applied to the web at a greater or lesser distance from a side edge of the web, and this is made possible in the design and construction of the instant applicator.

The applicator primarily is in the form of an initially solid block of metal or other suitable material, shaped to provide an elongate sleeve portion 10 having a chamber or elongate bore 12 to receive the cylindrical end 14 of a supply pipe 16 delivering glue or other liquid to the applicator. The supply pipe may be reduced in diameter where it fits the sleeve portion of the applicator,

3,298,353 Patented Jan; 17, 1967 ICC thereby to provide an annular shoulder 18 adapted to bear against a ring gasket 20 preventing leakage of liquid from the end 22 of the sleeve bore.

At its terminal end 24, the reduced section of the supply pipe may carry a screw-threaded stud 26 which passes through an end opening 28 of sleeve portion 10, to receive a nut 30 whereby thesleeve portion is detachably secured to the supply pipe. Removal of the single nut 30 is all that is required for disconnecting the applicator from the supply pipe for cleaning.

Supply pipe 16 and its reduced section 14 are provided with ablind bore 32 terminating at wall 34 and intermediate said wall and the shoulder 18 there is provided a plurality of openings or outlets 36 and 38 arranged transversely of the supply pipe at different distances from end 24. Pressurized glue or other liquid flowing in the direction of the arrows on FIG. 5, may enter the outlets 36 and 38 as is apparent.

Extending laterally from sleeve portion 10, and partly overlying the supply pipe 16, is a head section 40 to be referred to as the. lower section of the applicator head, said lower section 40 being overhung by an upper head section 42. The upper head section is spaced from the lower head section as shown in FIG. 1, to accommodate the travelling web. An upstanding neck 44 which may be integral with headsections 40 and 42, maintains the spaced relationship of the head sections. The intervening space between the head sections may be considered the throat 46 of the applicator head. In practice, the throat may be provided by milling a slot in the head parallel to the axis of sleeve portion10. The throat accommodates one side margin of the travelling web.

In order to convey fluid from the supply pipe to the upper and lower sections of the applicator head, a network of holes is drilled in the block constituting the applicator. Some of the holes are plugged, and others are provided with nozzle elements which may be interchanged with removable plugs to establish desired points of fluid discharge.

Nozzle tips are indicated at 48 and 50, and each nozzle element may comprise in addition to the tip, an externally threaded plug-shaped body 52 turned intermediate its ends to provide an annular channel 54. Channel 54 is adapted to register with a fluid supply passageway, so that fluid from a passageway may enter a transverse opening 56 within channel 54, which opening communicates with the tip and feeds fluid thereto as the fluid emerges from the tip to coat the travelling web. The nozzle elements may have socket heads 58 (FIG. 1) to receive a Wrench for unscrewing the nozzle element and removing it. In some instances a nozzle element removed may be replaced by a screw-threaded plug 60, similarly provided with a socket head or other means for application of a tool to rotate the plug.

From the foregoing, it will be understood that nozzle element 52 may be interchanged with the plug such as 60, to alter the location at which fluid will be applied to the web. Also, a plug 60 may be substituted for a nozzle element, to eliminate application of fluid to the web at the area of substitution.

Nozzle tip 50-, according to FIG. 5, may have direct communication with supply pipe outlet 36, for applying fluid to the under face of web W. The web so coated at 50 passes on through throat 46, where a transverse channel 62 provided in the lower section of the applicator head, provides relief under the coating to preclude wiping off the coating applied by nozzle tip 50. This of course, assures maintenance of a clear head and throat,

:screw 66 may be provided. Plug screw 66 may threadedly engage a tapped hole 68 extending transversely of bore 64, which it intersects, so that bore 64 and nozzle 50 may be closed by advancing the plug screw to the base 70 of bore 68.

In order to supply fluid to the nozzle member 52 in the upper section 42 of the applicator head, a hole 72 may be drilled from the rear of the lower head section, to intersect the outlet 38. Then another hole 74- may be 'drilled from the end face 76 of the lower head section to intersect hole 72, this bringing the fluid as far as the neck 44. Another hole 78 may then be drilled from the top of upper head section 42 downwardly to intersect hole 74; and finally, a hole 80 is drilled lengthwise of upper head section 42 to intersect hole 78, the final hole 80 being closed at its point of starting by a plug 82.

The point of drilling for hole 72 is closed by a plug ti l; that of hole 74 is closed by a plug 86; that of hole 78 is closed by a plug 88; and that of hole 80' is closed by the plug 82. By the above described network of drilled holes, fluid from the supply pipe is conveyed to the nozzle element 52 and plug 60, which latter may be replaced by a nozzle element similar to 52, if desired. A channel 90 similar to channel 62 may be provided in the upper face 92 of head section 40, to perform as does channel 62 to preclude wiping of fluid from the web as the latter progresses through throat 46. 7

As indicated by FIGS. and 6, the web W is subject to slight distortion wherever it passes over or under a nozzle tip, this being due to pressure of fluid discharging from the nozzle onto the web face. The indicated distortion of the web should be taken into account in establishing the depth of channels 62 and 90', and in determining the height of the throat between the upper and lower head sections 40 and 42. In FIG. 6 for example, channel 62 is made sutficiently deep to overcome any tendency of the force at nozzle tip 48 to depress against the lower section of the head, the coating applied by nozzle 50. s

In conclusion, it is noted that the device of the invention has no expensive moving parts subject to wear or maladjustment, and that long periods of uninterrupted service and reliability of operation are assured. The de vice moreover is simple and inexpensive to manufacture and maintain.

It is to be understood that various modifications and changes may be made in the structural details of the device, within the scope of the appended claims, without departing from the spirit of the invention.
