Apparatus for Applying Adhesive Substance to Sheets of Paper and™.
other Material.
I, FERDINAND EMIL JAGENBERG, Manufacturer, of Reichsstrasse, Düsseldorf,.
in the German Empire, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
Hitherto it has been usual to apply adhesive material to wallpapers and
other long sheets by means of a brush, which process is troublesome and takes.
much time, and the adhesive liquid applied in this manner is often unequally
distributed.
The present invention has for its object, to dispense with the use of a brush and.
avoid the drawbacks mentioned above.
In the accompanying drawings, Fig. 1 is a vertical section of an apparatus.
embodying my invention, and Fig. 2 is a front elevation of the same.
The apparatus chiefly comprises a narrow receptacle g, having immediately
above its bottom a pair of slots s, one along each of its long sides, said slots.
being just wide enough to allow the sheet of paper to be drawn through the
same.
As the adhesive liquid is comparatively thick, the said slots may be left open,.
even when they do not contain the paper. Each of the slots may, however, be
armed with an adjustable slide adapted to regulate the width of the slot, or the
bottom of the receptacle may be movable, so that it can be raised or lowered
relatively to the sides.
Slides may be applied also to the sides of the box g, for varying the length of the.
slots according to the width of the paper.
The receptacle g, together with accessories, is mounted on a cast iron stand
or pair of stands n, which carry a cradle m for the roll of paper, and a guide-
roller w, or several guide rollers for guiding the paper on its way to the slot of the
box g.
.
Ou that side, where the paper or travelling sheet comes out of the box g, a.
vertically movable slide a is mounted, which can be placed higher and lower by
means of set screws. In the example shown by the drawing, the slide a is attached
to springs fand controlled by set screws c adapted to draw the slide downward in.
opposition to the upward pressure of the springs f.
The said set screws c abut against the baseplate or frame p, and are screwed
through the slide a, so that by turning the screws to the right, the slide a will be-
drawn down. This slide a may carry at its upper edge a friction roller, and serves.
to guide the paper upward more or less, after it has left the box g.
By varying the position of this slide, and therefore the angle at which the paper-
issues from the slot of the box g, the thickness of the layer of adhesive liquid on the
paper may be regulated. If the slide stands high and the paper therefore rises at
a sharp angle, more of the adhesive liquid is scraped off, than when the paper passes.
out of the receptacle almost horizontally.
It is evident, that not only wallpapers, but also sheets of textile fabrics,.
leather, and other materials, may be provided with adhesive liquid by means of this.
apparatus.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :
1. In apparatus for applying adhesive liquid to sheets of paper and other material
by causing the sheets to pass over the bottom of a receptacle for adhesive substance,
the combination of a receptacle having in its side walls immediately above the
bottom a pair of slots, with a vertically adjustable slide situated on the delivery
side and adapted to vary the angle at which the travelling sheet leaves the said
receptacle, substantially as described.
2. Apparatus for applying adhesive liquid to sheets of paper and other material,
substantially as described and represented by the drawings.
