Improvements in connection with Apparatus for Finishing,
Stretching, Mordanting, and Drying Textile Fabrics."
I MANUEL BECK of 58 Oppenheimer Landstrasse, Frankfort-on-Main in the
Empire of Germany, Engineer and Manufacturer do hereby declare the nature of
this Invention to be as follows:-
The object of this Invention is to provide a simple arrangement of apparatus
whereby textile fabrics can be finished stretched and dried by a continuous
process without any accumulation of material between the sizing or glossing
process and the stretching and drying process as heretofore and whereby also a
saving of labour is effected.
According to this Invention the trough or vessel containing the sizing or gloss-
ing mordanting or like material is arranged close to the stretching or tentering
frame; and the said trough or vessel, as well as the space between it and the
stretching frame, are provided with rollers furnished with spikes or pins or with
frictional surfaces adapted to engage the fabric and feed it as it leaves the trough
or vessel containing the glossing or like material direct to the tenter or stretching
frame
In apparatus hitherto employed in finishing and drying fabrics, one operative
agency is employed for bringing the fabric into the glossing apparatus; while two
other applications of power are necessary for conveying the fabric to the stretching
frame, whereas in the arrangement of apparatus according to this Invention a
single working power only is necessary for feeding the fabric into the trough or
vessel containing the glossing or like material and for uniformly traversing the
fabric towards the stretching frame or tenter, which may be of the ordinary
construction.
The trough or vessel containing the finishing fluid, mordant, or the like, is
fitted, not, as hitherto, with guide rollers, but with any desired number of
rollers furnished or clothed with pins or spikes, so that, as the fabric enters the
trough, or vessel, it is thoroughly gripped and stretched therein.
After the material has passed the rollers and before it reaches the tenter, or
stretching frame, it is engaged by other spiked rollers of any desired number
situated in the space between the trough or vessel and the tenter or stretching
frame in such a manner as to prevent the material from being shifted out of
position.
Means are provided by which in case of the rollers in the trough or vessel
exercising undue tension on the fabric, the said rollers will yield and relieve the
fabric from excess of pressure.
The spiked rollers, in many cases, may be replaced by rollers acting by adhesion

page_text: or frictional contact, the material employed in their construction being, say, for
instance, india-rubber, or some suitable metal casing, capable of acting on the
fabric much in the same way as the spiked rollers.
The improved machine may be utilized for finishing and drying, or for mordant-
ing and stretching, textile fabrics.

· Improvements in connection with Apparatus for Finishing,
Stretching, Mordanting, and Drying Textile Fabrics."
I, MANUEL BECK of 58 Oppenheimer Landstrasse, Frankfort-on-Main, in the
Empire of Germany, Engineer and Manufacturer, 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 provide a simple arrangement of apparatus
whereby textile fabrics can be mordanted or finished mercerised stretched and
dried by a continuous process without any accumulation of material between
the sizing or glossing or like process and the stretching and drying process as
heretofore and whereby also a saving of labour is effected.
According to this Invention the trough or vessel containing the sizing or gloss-
ing mordanting or like liquor is arranged close to the stretching or tentering
frame; and the said trough or vessel as well as the space between the squeezing
rollers and the stretching frame are provided with rollers furnished with spikes or
pins or with frictional surfaces adapted to engage the fabric and feed it as it
leaves the trough or vessel containing the glossing or like materials direct to the
tentering or stretching frame.
The trough or vessel containing the finishing fluid, mordant, or the like, is
fitted, not, as hitherto, with simple guide rollers, but with any desired number
of rollers furnished or clothed with pins or spikes, so that, as the fabric, enters the
trough, or vessel, it is thoroughly gripped and stretched therein.
After the material has passed through the trough and the squeezing rollers
and before it reaches the tentering or stretching frame, it is engaged by any
desired number of adjustable spiked rollers arranged between the squeezing rollers
and the tentering or stretching frame in such a manner as to prevent the material
from being shifted out of position.
1.
When this apparatus is employed for mercerising and stretching fabrics, the
fabric is carried by the tentering or stretching device into and through a tank
containing water or diluted acid to remove from the fabric while stretched, the
lye contained therein.
The mordanting or finishing stretching and drying operations effected by this
improved apparatus requires the attendance of only one person whose duty is. to
feed the fabric at the commencement into the trough or vessel containing the
mordanting or finishing substance from whence it passes directly on to the
tentering or stretching frame, in which it is stretched, so that the fabric cannot
of itself become displaced.
In subjecting fabrics to the mercerising and stretching operation by means of
this device, the whole process can be carried out in a continuous manner, the

page_text: fabric being passed through the trough containing soda lye being stretched and
rinsed at one continuous operation.
Means are provided by which in case the fabric should undergo too intense a
tension in longitudinal direction by the stretching operation, the pressure of the
rollers of the finishing machine can be relieved so as to allow the fabric to pass
more freely between them.
The spiked rollers, in many cases, may be replaced by rollers acting by adhesion
o frictional contact, the material employed in their construction being, say, for
instance, india-rubber, or some suitable metal casing, capable of acting on the
fabric much in the same way as the spiked rollers.
The improved machine may be utilized for mordanting finishing and drying or
for mercerising and stretching textile fabrics.
Figure 1 of the accompanying drawings is a side sectional elevation of an
apparatus constructed according to my Invention for mordanting or finishing
stretching and drying textile fabrics and Figure 2 is a view similar to Figure 1
but provided with an additional tank in which the mercerised fabrics can be
washed in a stretched condition. A is a trough or vessel containing the finishing
fluid, mordant or the like with which the fabric B is to be treated the said trough
or vessel being provided in the interior with rollers a a clothed with card teeth on
otherwise roughened to engage with the fabric as it passes through the trough the
said fabric passing beneath and in contact with the said rollers which are immersed
in the fluid. The fabric after passing from beneath the rollers a passes between
squeezing rollers bb by which superfluous finishing fluid or the like, is pressed
out of the fabric, which on leaving the rollers 61 enters between another pair of
rollers having roughened surfaces or clothed with card teeth like the rollers a.
On leaving the rollers c the fabric is directly engaged at its edges by the hooks or
clips of a tentering or stretching frame shewn diagrammatically at C by which
the fabric is stretched after which it is conducted by guide rollers d to a beam or
roller e on which it is wound. The fabric is dried in its passage through the
stretching frame and on its way to the roller or beam e. When the apparatus is
used for mercerising and stretching fabrics a trough D containing water or diluted
acid is provided beneath the tentering or stretching frame as shewn in Figure 2
through which water or the like the fabric is caused, by the tentering clips or the
like, to travel so that the fabric while being stretched is rinsed and cleansed from
The
any lye it may contain before it passes to the winding beam or roller e.
roller 6 between which and the rollers the fabric passes, after leaving the
trough A is mounted in sliding bearings which are connected by a cord or chain 63
to a counter weight which will prevent the roller 61 from pressing too forcibly
upon the fabric and thus preserve the fabric from damage while being stretched.
Having now particularly described and ascertained the nature of my Inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In apparatus for mordanting, or finishing, stretching, and drying textile
fabrics, the combination with a trough to contain the mordanting or finishing.
fluid or the like, of rollers clothed with card teeth or provided with an equivalent
covering or surface and arranged to rotate beneath the surface of the fluid in the
trough in contact with the fabric to be treated, pressing rollers through or between
which the fabric passes and is pressed after leaving the fluid in the trough, and
rollers clothed with card cloth or provided with equivalent covering or surfaces
between which rollers the fabric after leaving the pressing rollers passes direct
onto a tentering or stretching frame by which the fabric is stretched, the several
parts being arranged that the fabric can be mordanted, or finished stretched and
dried by one continuous process substantially as hereinbefore described.
2. The combination and arrangement of this apparatus for mercerising and
stretching by which the fabric in a stretched condition is caused to pass through a

page_text: water bath, or a bath of dilute acid to wash the fabric or to liberate any caustic
soda or the like contained in the fabric substantially as hereinbefore described.
