Improved Apparatus for Dyeing or Chemically Treating and Drying
Paper, Felt, or other Fabrics.
We WILLIAM SEARLE of 4 Playhouse Yard Water Lane London Secretary
of Rogers Copying Company Limited and WILLIAM HENRY ELLIOT of
41 Oxford Road Finsbury Park London Commercial Traveller 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:-
The object of this invention is to construct a machine or an apparatus for
saturating tissue papers with a chemical solution and which will also dry the said
paper after saturation and which apparatus shall also be applicable for dyeing
drying damping dressing with chemical solutions starching varnishing or otherwise
treating paper and felted woven or knitted fabrics.
The accompanying drawing represents a machine for saturating tissue paper
constructed according to this invention.
Now according to this invention we provide a suitable bath a to contain the
chemical solution dye varnish or other substance in a liquid state with which the
paper or other fabric is to be treated in this bath dipping below the surface of the
contained liquid is a roller 6 made of copper or other material which is not acted on
by the solution in the bath a ductor roller c which has its axis approximately in the
same horizontal plane rotates in contact with the roller b and transfers the solution
to a roller d covered with felt or other suitable material vertically beneath the
ductor roller c.
The covered roller d rotates in contact with a hollow drum e heated by steam or
other suitable means and caused to rotate at a suitable speed by means of a pinion f
shewn in dotted lines carried on a shaft or stud g carrying also a pair of fast and
loose pulleys h to the former of which the pinion is attached and a spur wheel of
which the pitch line only is shewn by the dotted circle i secured to the trunnion
axis of the drum e gearing with the pinion. In contact with the drum e and
rotating therewith is an endless web or blanket k of about the same width as the
drum e this web or blanket is carried by guide rollers l m n o p q r rotating in
bearings adjusted by the screws l m n o p q r¹ springs being interposed between
the bearings and the nuts to ensure an equal pressure of the web or blanket k on the
circumference of the drum e and to prevent creasing s is a stretching roller.
The web k passes round the roller / round the periphery of the drum e round the
roller r over the rollers 9 and p under the rollers and thence over the rollers on m
back to the roller l.
The sheets of paper to be saturated are placed on the feeding table t and fed in
between the roller d and the drum e the former saturating the paper with the
solution and the latter drying the saturated paper as it is carried round between the
drum and the blanket the dried sheet is removed from the drum e by a strip of
metal or
"doctor" u preferably curved as shewn and falls on the taking off table v.
The "doctor" is preferably mounted in a frame pivoted to the main frame w and
the pressure of the "doctor on the drum e adjusted by weights sliding on levers
secured to or formed integral with the "doctor" frame.
By adding suitable reels for feeding to the saturating roll and taking off the
finished material paper or other fabrics may be treated in a continuous length
instead of in sheets the reels being driven by friction or other suitable gearing which
will allow of the taking off reel to maintain a uniform tension on the finished fabrics.
is a tank to contain the solution from whence it runs to the bath d in which the
liquid is maintained at a constant level.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. In an apparatus for dyeing or chemically treating and drying paper felt or
other fabrics the combination of an endless web or blanket in contact with a heated
roller with a series of adjustable guiding rollers all substantially as described.
2. In an apparatus for dyeing or chemically treating paper felt or other fabrics
the combination of a heated drying roller a saturating roller rotating in contact
therewith a bath for containing the solution rollers for transferring the solution to
the saturating roller and an endless web or blanket all substantially as described.
3. The improved apparatus for dyeing or chemically treating and drying paper
felt or other fabrics substantially as described and shewn and operating in the
manner specified.
Dated this 3rd day of February 1892.
