Apparatus for Coating Sheets of Paper, Woven Fabrics, Leather, and
the like, with Thin Paste, Liquid Gum, or other Liquids that will
Adhere to the same.
I, EMIL JAGENBERG, Junior, Manufacturer, of Reichstrasse, 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:-
This invention relates primarily to an apparatus designed to supersede the
familiar spreading plate or board, by means of which paste, or size, has been
hitherto applied to sheets of paper and like articles, and is adapted to spread the
adhesive substance rapidly and evenly, without any portion of it being wasted,
as in the case of the spreading plate; without any wear of brushes, and without
the necessity of employing skilled labour, but the invention is applicable generally
for coating sheets or strips of paper, woven fabrics and the like with liquids,
that will adhere to the same.
In the accompanying drawings, Fig. 1 is a side elevation of an apparatus
embodying my invention; Fig. 2 is a longitudinal section, and Fig. 3 a plan of
the same.
The device comprises in its construction a roller W, which either dips into the
paste or size trough direct, or to which paste is supplied through the medium of one
or more other rollers or equivalent mechanism. Where, as in the example illustrated
in the drawings, a paste-supplying or priming roller is provided; this roller is
placed at a predetermined distance from the roller W. This distance is rendered
controllable, either by providing the roller with adjustable bearings, or by con-
structing one or both of the rollers with laterally projecting edges or flanges. In
front of the roller W are mounted the paper feeding rollers a and b. The peri-
pheral speed of these rollers a, b, is preferably less, than that of the roller W,
in order that the said roller W may perform a sweeping or brushing motion under
the paper, owing to which motion the adhesive medium is transferred to the
paper in a more satisfactory manner.
In order, that the paper may come in contact with as large a portion as possible
of the periphery of the roller W, the rollers a and b should be mounted lower
than the axis of the said roller W, and in such a relative position to each other,
that the paper passing through between them is directed upwards and may with
certainty be taken along in the upward direction by the roller W.
In the rear of the roller W there are arranged a number of strippers S adapted
to remove the sized sheet of paper from the roller. These strippers are preferably
arranged sufficiently close together to be capable of lifting even the narrowest strip
of paper off the roller, while at the same time they should be so narrow, as not to
be liable to scrape off the layer of size or paste. The tablet serves to hold the pile
of sheets of paper to be operated upon, so that the sheets need be removed but
slightly on their way to the machine, after which the latter does all the rest auto-
matically. Textile fabrics, leather and the like may be sized or coated with
liquid by means of this device in the same way as paper.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. Apparatus for applying adhesive liquid to sheets or strips of paper, woven
fabrics, leather and the like, comprising in its construction a roller adapted to
take up the adhesive liquid, and feed rollers arranged in front of the same, the
whole being adapted to operate substantially as described.
2. A pasting, sizing or coating apparatus constructed and adapted to operate
as described and illustrated by the drawings.
