page_text: We, IIFINRICH PAM and SAMUEL PAM, Paper Spool Manufacturers, both of
Neunkirchen, Austria do hereby declare the nature of our said invention to be as
follows:-
Our invention relates to spools for winding yarn and such like, and has for its
object the manufacture of such improved spools of paper. These spools are composed
of the body or tube, of the two flanges at the end of the latter and of a short bushing
nt either end of the said tube.
For manufacturing such spools we first produce paper tubes of different inside
and outside diameters, by winding paper of any desired width, to which a glue is
applied, upon a mandrel the diameter of which corresponds to the inside diameter
of the tube to be formed. In this manner the paper is wound tightly upon the
maudrel until a tube of the desired outside diameter has been formed. Of such
tubes three kinds are required for the production of a spool, uz one kind, the size
of which corresponds to the tubular body of the spool, one kind, the inside diameter
of which fits the outside diameter of said bushings of the spool, while its outside
diameter corresponds to the diameter of the flange to be produced, and a third kind,
for the bushings, which fits into the tubular body of the spool, and the inside
diameter of which corresponds to the spindle upon which the spool is to be used.
From the paper tube, intended for the flanges, disks are cut off of a thickness a
little greater than the finished flange is to have. The other tube, intended for the
bushings, is likewise cut into suitable lengths. Now one of the aforesaid flange-
disks is glued upon the end of each of the said bushings in such manner that this
end projects a little beyond the face of the flange, so that it may be bordered down
against said face of the flange The flange and bushing thus united are now
brought between the dies of a press and there compressed into a solid body of the
desired dimensious.
The paper tube for the body pieces of the spool having also been cut into suitable
lengths, a bushing, provided with a flange in the described manner, is glued into
each end of a body piece whereby the spool is completed. These spools may yet be
turned off and varnished or polished to finish them ready for the market.

We, HEINRICH PAM, and SAMUEL PAM, Paper Spool Manufacturers, of
Neunkirchen, Austria, do hereby declare the nature of our said invention and in what
manner the same is to be performed, to be particularly described and ascortained in
and by the following statement —
Our invention clates to spools for winding yarn and such like, and has for its
object the manufacture of such improved spools of paper.

page_text: These spools are composed of the body on tube, of the two flanges at the end of
the latter, and of a short bushing at either end of the tube.
In the annexed drawing, Fig. 1 shows a spool of this kind in side view, partly in
section, and Fig 2 is an end view of the spool Fig. 3 shows a section of the same
spool with a modified flange.
As will be seen from the diawing, our improved spool consists of the tube or
cylinder a, of the two flanges b, and of the two bushings c.
In the manufacture of these spools, paper tubes of different inside and outside
diameters are used, which are produced in the well known manner, by winding paper
of any desired width, to which a glue is applied, upon a mandrel the diameter of
which corresponds to the inside diameter of the tube to be formed. The paper is
thus wound tightly upon the mandrel until a tube of the desired outside diameter
has been formed. Of such tubes three kinds are requied for the production of our
improved spool, tizone kind the size of which corresponds to the tubular body a
of the spool, another kind the inside diameter of which corresponds to the outside
diameter of the bushings c, while its outside diameter is that of the flange b to he
formed, and a third kind, for the bushings c, which fits into the tubular body a of
the spool, and the inside diameter of which corresponds to the thickness of the
spindle upon which the spool is to be used.
From the paper tube intended for the flanges, discs are cut off, of a thickness
somewhat greater than the finished flange is intended to have. The other tube
intended for the bushings is likewise cut into suitable lengths Now one of the
aforesaid flange-discs is glued upon one end of each of the bushings in such
manner that this end projects a little beyond the face of the flange. This
projecting end of the bushing is now bordered down upon the flange by means
of one of the well known devices for this purpose, whereupon the flange and
bushing thus united are brought between the dies of a press and there complessed
into a hard and solid body of the desired dimensions.
The paper tubes for the body pieces of the spools also having been cut into
suitable lengths, a bushing provided with a flange in the described inannet is glued
into each end of this tube a, whereby the spool 15 completed
These spools may
yet be turned smooth and vanished or polished to finish them ready for the
market.
Instead of cutting the flanges b from long tubes, they may also be formed singly,
the same as the long tube, by employing strips of paper having a width suitable for
one flange only.
b
The flanges may also be produced from two, three or more tubes of different
diameters, fitting one into the other, as indicated in the sectional view, Fig 3.
These tubes are, either before or after they have been cut off, glued into each other,
so as to form a tube or ring of the desired dimensions of the flanges.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. Improved spools for yarn and such like, made exclusively of wound paper
tubing and consisting of the body or tube a, the flanges b, and the bushings c,
substantially as described.
2. Improved spools for yain and such like, produced from wound paper tubing
of three sizes, one corresponding to the body a, one to the flanges and one to the
bushings c, by cutting the cfrom suitable lengths for the sand three parts, inserting
the bushings into the flange discs, bordering the end of these bushings c down upon
the outside face of the flanges b, compressing the glued together flanges and
bushings into the desired dimensions, and finally inserting and glueing the bushing c
with their fice ends into the ends of the body tubes, substantially as described.
3. Improved spools for winding yan and such like, of the kind herein described,
in which the flange discs are formed by winding a strip of glued paper of the width

page_text: of the disc to be produced upon a suitable mandrel until the desired outside diameter
has been obtained.
4. Improved spools for winding yarn and such like, of the kind herein described,
in which the flange discs are formed from two or more paper tubes of different
diameters, and fitting one into the other, substantially as described.
