PROVISIONAL SPECIFICATION.
Improvements in or relating to Fulling Machines and the like.
I, LEOPOLD PHILIPP HEMMER, Machine Manufacturer, of Krugenofen No. 62,
Aix-la- Chapelle, Prussia, do hereby declare the nature of this invention to be as
follows:-
This invention relates to fulling machines and the like.
In addition to stamping and crank fulling machines cylindrical rollers known
generally by the name of fulling cylinders have also been used up to the present
time for fulling textile fabrics.
The present invention relates to fulling machines in which, instead of cylin-
drical rollers, rollers are employed the surfaces of which are profiled curved or
other than straight by which arrangement the following advantages are obtained.
1). The textile fabric treated by such rollers is concentrated in the central part
like a hank so that it can be fulled afterwards in the direction of its breadth
which can be done better than in the cylindrical fulling process, where one
straight cylindrical roller presses on one of the same shape underneath, in which
the material passing between them has a tendency to broaden out towards the
edges of the rollers.
The excessive broadening out of the material cannot take place with these new
rollers, the working surface of the rollers being more or less inclined or curved
inwards in consequence of which the material passing between them is prevented
from broadening out and is concentrated more or less in or towards the centre.
In consequence of the marked concentration in the central part of the shaped
rollers, the pressure of the upper roller on the material is more elastic and more
effective and the fulling of the material in breadth is more rapidly effective.
2). The new profiled rollers cause the different lavers of the textile fabric to
slide one over another and compel the creases in the fabric to change their position
at each passage between said rollers, owing to the different circumferential
velocities of the working surfaces of the rollers.
3). In consequence of the friction between the different parts of the material
passing through the profiled rollers a better felting of the material is obtained.
The material to be fulled passes over a guide roller and through an entrance
guide between the principal working rollers and through the outlet passage to the
bottom of the fulling machine.
The profile of the circumference of the working rollers is a curve or incline
which can be of various forms.
The scrapers or plates arranged on the discharging side of the chief working
rollers are shaped to correspond to the profile of the rollers they serve.
The scrapers are connected respectively to the outlet table and to the cover.

page_text: I, LEOPOLD PHILIPP HEMMER, Machine Manufacturer, of Krugenofen No. 62,
Aix-la-Chapelle, Prussia, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and as-
certained in and by the following statement:-
-
This invention relates to fulling machines and the like.
In addition to stamping and crank fulling machines cylindrical rollers known
generally by the name of fulling cylinders have also been used up to the present
time for fulling textile fabrics.
The present invention relates to fulling or like machines in which, instead of
cylindrical rollers, rollers are employed the surfaces of which are profiled curved
or other than straight by which arrangement the following advantages are ob-
tained.
1). The textile fabric treated by such rollers is concentrated in the central part
like a hank so that it can be fulled afterwards in the direction of its breadth
which can be done better than in the cylindrical fulling process, where one
straight cylindrical roller presses on one of the same shape underneath, in which
the material passing between them has a tendency to broaden out towards the
edges of the rollers.
The excessive broadening out of the material cannot take place with these new
rollers, the working surface of the rollers being more or less inclined or curved
inwards in consequence of which the material passing between them is prevented
from broadening out and is concentrated more or less in or towards the centre.
In consequence of the marked concentration in the central part of the shaped
rollers, the pressure of the upper roller on the material is more elastic and more
effective and the fulling of the material in breadth is more rapidly effected.
2). The new profiled rollers cause the different layers of the textile fabric to
slide one over an other and cause the creases in the fabric to change their
position at each passage between said rollers, owing to the different circumferential
velocities of the working surfaces of the rollers.
3). In consequence of the friction between the different parts of the material
passing through the profiled rollers a better felting of the material is obtained.
In the accompanying drawings several examples of such profiled rollers are
represented.
Figure 1 represents a longitudinal section of the principal rollers of a machine.
Figure 2 being a front view and
Figure 3 a top view with the upper roller and guide board removed.
Figures 4, to 9 show different alternative forms of rollers for a fulling machine.
The material to be fulled passes over the guide roller i and through the entrance
guide between the principal working rollers a, b, and through the outlet passage
to the bottom of the fulling machine.
The profile of the circumference of the working rollers a and b, k and 1, m and
n. o and p, q and r, s and t, u and r, is a curve or incline or curves and inclines
which can be of various forms, as shown in Figures 2, 4, 5, 6, 7, 8 and 9 by way
of example and it is possible to profitably employ other curves or forms of pro-
files for the rollers.
The serapers or plates ed arranged on the discharging side of the chief working
rollers a and b are shaped to correspond to the profile of the rollers they serve.
The said scrapers c and d are connected respectively to the outlet table f and
the cover e.
The cylinder forms represented in Figures 4, 7, 8 and 9, leave a greater passage

page_text: for the work towards the centre than at the edges. In consequence of this ar-
rangement the work is kept more effectively together, thereby receiving the
pressure more evenly.
The shape of the cylinder is chosen according to the weight and description of
the material to be treated.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is
1. A fulling machine characterised by the chief working rollers having such
profiled working surfaces as to produce a friction between the different parts of
the material passing between them and to concentrate the material in the central
or lower portions of said roller surfaces owing to the different circumferential
velocities of the working surfaces substantially as described.
2. Rollers for fulling or like machines of such shape that they leave a greater
passage for the work to be treated between them towards the centre than at the
edges whereby a more evenly distributed pressure, as well as a more even felting,
and felt formation, is obtained.
3. Rollers for fulling or like machines substantially as described or illustrated
in Figures 2, or 4, or 5, or 6, or 7, or 8, or 9 of the accompanying drawings.
