COMPLETE SPECIFICATION.
Apparatus for Stretching Stuffs or Fabrics.
I, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, as cominunicated to me by Christian
Dierig, Manufacturer, and Gustav August Falke, Director of Weaving Mill, both
of Oberlangenbielau, Silesia, Germany, to be particularly described and ascertained
in and by the following statement:-
This invention relates to apparatus, for stretching stuffs or fabrics, in which the
use of cog-wheels as hitherto employed for gearing the stretching rollers together
is dispensed with. This is effected by the employment of rollers made of rubber
and of a conical shape which lie with their circumferences against an intermediate
cylindrical roller.
The accompanying drawings shew an example of apparatus for stretching stuffs
or fabrics constructed according to this invention. Fig. 1 is a section Fig. 2 an
end elevation and Figs. 3 and 4 plan views, the latter with the top cover g
removed.
The same letters of reference indicate the same parts in the various figures.
The cylindrical intermediate roller b is made of rubber, and one end of its axle a
rotates in a bearing d formed in the principal or main part e of the frame, while
the other end of said axle a rotates in a bearing formed in a downward
prolongation f on one end of the cover g; said cover g being connected at the
other end to the main part e of the frame, see Figs. 1 and 2. By this construction
it is possible to introduce the edges of the stuff or fabric between the conical
rubber rollers h h and the intermediate cylindrical rubber roller b.
On one end of the axle a is fixed a hand wheel c by means of which the
cylindrical roller b can be rotated so as to enable the workman to pass the stuff or
fabric out from between the rollers when so desired.
In this arrangement, as in all stretching apparatus hitherto employed, the
rollers are rotated by the drawing of the stuff or fabric between them.
The conical rollers -h are so placed in the principal or main part e of the
frame that their reduction of size lies towards one end of the apparatus, which
takes only part of the width of the stuff or fabric, consequently the rollers hh
taper towards the centre of the stuff or fabric. By the rotation of the rollers.
the stuff or fabric is drawn in an undulating manner between them and is laterally
stretched from the centre outwards by reason of the shape and disposition of the
conical rollers without tearing or spoiling the stuff or fabric, contrary to the
manner where cog-wheels are employed, which have hitherto been deemed to be
indispensable.
Besides the example shewn in the drawings a number of others can be produced
in such a manner that the number of elastic rollers can be changed or the
arrangement constructed differently according to requirements.
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 ;-
Apparatus for stretching stuff's or fabrics comprising conical elastic rubber

page_text: rollers reduced in size from one end of the apparatus and working together with
an intermediate cylindrical roller substantially as and for the purpose hereinbefore
described.
