Improvements in the Process of and Means for Finishing or Dressing
Textile Fabrios.
.
I, GUSTAV BERNHARD GERLACH, of the firm of Kettling and Braun, of the City
of Crimmitschau, in the Kingdom of Saxony and German Empire, Manufacturer,
do hereby declare the nature of this invention to be as follows:
My invention relates to improvements in the process of and means for finishing
or dressing textile fabrics, particularly woven fabrics such as dress goods which are
calendered or pressed under the application of heat in order to give them a smooth
surface, a firm feel, and an attractive lustrė.
The work person who has to sew dress goods and the like requires that they
shall be in a suitable condition and such goods are considered to be ready for the
needle when they do not shrink any further or deteriorate in appearance under
the application of a tailor's iron and damp cloth, nor change materially, when made
up, by exposure to the weather.
The object of my invention is to so finish goods of the indicated nature that they
will fulfil all the above specified requirements and I accomplish this object by the
following process and apparatus.
'
I employ an endless band of cloth or other suitable material travelling round a
revolving roller and any convenient number of guide rollers. Beneath the revolv-
ing roller is a correspondingly shaped hollow basin or vessel over which is another
endless band kept in motion by another revolving roller. The upper cloth or
both cloths may be kept moist by any convenient means and if necessary the
surplus moisture may be removed by a pair of squeezing rollers.
The woven or other fabric to be treated is passed between the two travelling
cloths and is pressed between the revolving roller and hollowed basin both of
which are heated. The basin or vessel may be placed above instead of below tho
revolving roller, or instead of the basin and roller, two calender rollers may be
employed, and one of the endless bands might be dispensed with.

page_text: 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:-
My invention relates to improvements in the process of and means for finishing
or dressing textile fabrics, particularly woven fabrics such as dress goods which are
calendered or pressed under the application of heat in order to give them a smooth
surface, a firm feel, and an attractive lustre.
The work person who has to sew dress goods and the like requires that they
shall be in a suitable condition and such goods are considered to be ready for the
needle when they do not shrink any further or deteriorate in appearance under
the application of a tailor's iron and damp cloth, nor change materially when made
up, by exposure to the weather.
The object of my invention is to so finish goods of the indicated nature that they
will fulfil all the above specified requirements and I accomplish this object by the
following process and apparatus.
I employ an endless band of cloth or other suitable material travelling round a
revolving roller and any convenient number of guide rollers., Beneath the revolv-
ing roller is a correspondingly shaped hollow basin or vessel over which is another
endless band kept in motion by another revolving roller. The upper cloth or
the lower cloth is to be kept moist by any convenient means. The woven or other
fabric to be treated is passed between the two travelling cloths and is pressed
between the revolving roller and hollowed basin both of which are heated. The
basin or vessel may be placed above instead of below the revolving roller.
The arrangement illustrated by the accompanying drawing, consists mainly of
the rotary cylinder or roller a round which runs the endless travelling band e of
cloth or other suitable material capable of absorbing moisture, and this band e
passes over two or more rollers or guides h. Below the roller a is the stationary
hollow basin b round which runs the endless travelling band d of felt or other
suitable material, the band passing over rollers or guides ' and being actuated by
a rotating roller. The band e is kept moist by means of a water jet for any
other convenient and suitable arrangement.
The band d is kept dry and the roller a and basin bare heated by means of steam
or other means.
When the apparatus is working the material to be treated enters in the direction
indicated by the arrows and passing between the two travelling bands d and e is
damped by the cloth e whilst receiving simultaneously heat and pressure. In con-
sequence the moisture absorbed by the material begins to evaporate and
the resulting steam penetrates the material under the pressure to which it is sub-
jected' whilst the excess of vapour is absorbed by the band d which moves with it.
The material issues from between the pressure roller and basin with a lustrous
finish on both sides, the lustre being duller on the upper than on the lower side,
and saturated with sufficient moisture to prevent it shrinking further.
The material having been kept continuously under pressure during the damping
process presents a completely even and uniform face with a permanent finish.
Moreover as the two bands which cover the material all the time it is being pressed
travel with it there is no strain or change in the position of its fibres. If it be
required that both sides of the material shall have the same finish and appearance
the material must be turned over and taken in this position through the apparatus
once more.
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 I claim
is:-
1. In combination the rotary heated roller a and the stationary heated hollow
basin .

to continuous pressure substantially as herein set forth.
2. The general combination and arrangement of parts embodying my improve-
ments in the process of and means for finishing or dressing textile fabrics substan-
tially as herein set forth.
