GEORG MARWITZ of Thicket Road Penge in the County of Surrey " IMPROVE-
MENTS IN THE PROCESS AND APPARATUS FOR DRESSING STIFF NET AND SUCH
LIKE FABRICS". [Communicated to him from abroad by Gustav Heinrich Gruner
of Dresden in the German Empire.]
This invention relates to means of dressing, and thereby rendering stiff and
glassy, net and fabrics of like character. For this purpose, I first starch the piece
of fabric and then I stretch it on a frame which is provided with screws so as to
open it laterally with such strain on the fabric as is found necessary. The frame
is provided with wheels running on rails so that it can be run into a chamber in
which the stretched fabric is subjected for a few minutes to steaming. The frame
is then withdrawn from the steaming chamber and the fabric, after it is dried, is
removed from the frame in a finished condition. When additional stiffening is
required, the steamed fabric, which may be moistened by cold water brushed over
it, is powdered over with starch dust applied in the following manner.
is run on wheels along the length of the frame, this vehicle containing finely
pulverised starch, and having a silk such as is employed in flour dressing machines
stretched over a frame at its bottom. The axles of the vehicle have on them cams
which, as the vehicle runs along, actuate hammers that strike the silk frame, thus
causing the fine particles of starch to pass through the pores of the silk to the
fabric below. The fabric when thus dusted with starch is again run into the
steaming chamber and is there steamed for about a quarter of an hour, whereupon
it is withdrawn in a finished condition.

IMPROVEMENTS IN THE PROCESS AND APPARATUS FOR DRESSING STIFF NET AND
SUCH LIKE FABRICS A communication to me from Abroad by Gustav Heinrich
Gruner of Dresden in the German Empire
"
My invention relates to means of dressing, and thereby rendering stiff and glassy,
net and fabrics of like character. For this purpose, I first starch the piece of
fabric and then I stretch it on a frame which is provided with screws so as to open
it laterally with such strain on the fabric as is found necessary. The frame is
provided with wheels running on rails so that it can be run into a chamber in
which the stretched fabric is subjected for a few minutes to steaming. The frame
is then withdrawn from the steaming chamber and the fabric after it is dried is
removed from the frame in a finished condition. When additional stiffening is
required, the steamed fabric which may be moistened by cold water brushed over
it is powdered over with starch dust applied in the following manner. A vehicle
is run
on wheels along the length of the frame, this vehicle containing finely
pulverised starch, and having a silk, such as is employed in flour dressing
machines, stretched over a frame at its bottom. The axles of the vehicle have on
them cams, which as the vehicle runs along, actuate hammers that strike the silk
frame thus causing the fine particles of starch to pass through the pores of the
silk to the fabric below. The fabric when thus dusted with starch is again run in
to the steaming chamber and is there steamed for about a quarter of an hour,
whereupon it is withdrawn in a finished condition.
Fig. 1 of the accompanying drawings is a longitudinal section partly in elevation,
and Fig. 2 is a plan of apparatus according to this invention for operating as above
described. Fig. 3 is a half transverse section and half end elevation of the
steaming chamber. The frame on which the fabric is stretched is run on rails A
into the steaming chamber which is closed tightly by a door B. Steam is admitted
to pipes C which extend along the chamber and have numerous perforations
through which the steam issues. The water of condensation is discharged by a
siphon outlet D. To prevent dripping from the roof of the chamber, it is made
with sloping partitions E. For powdering with starch, the starch box F is run
along over the fabric while it rests on the framing G.
:
Having thus described the nature of this invention and in what manner the
same is to be performed, as communicated to me by my foreign correspondent, I
claim :-
First. The herein described process for dressing stiff net and similar fabrics.
Second. The construction of apparatus for dressing stiff net and similar fabrics,
combined and operating substantially as herein described with reference to the
accompanying Drawings.
In Witness whereof I the said Georg Marwitz have hereunto set my hand
and seal this twenty fifth day of August in the year of our Lord One thousand
eight hundred and eighty-three.
