Braunsihweig, German Empire residing at Hamburgerstrasse 37 and 38 in the
City of Braunsihweig, do hereby declare the nature of the said Invention for

"
This Invention relates to the manufacture of a tube like non-conducting or
insulating material chiefly intended for covering cold conduits or pipes. The
manufacture is carried into effect by plaiting (by means of a braiding or plaiting
machine) a dense hollow tube or hose which during its production is filled with a
non conducting material, say kieselguhr, pulverized cork, ashes, or paper, which
may be in a pulverulent or a pasty condition.
To this end the tube or hose is plaited on a special ring and in the centre of the
ring there is a funnel shaped pipe the lower end of which extends into the tube, or
hose being made and contains a screw which forces the non-conducting material
into the tube so that the latter is delivered by the machine ready filled.
The construction of the machine employed in this manufacture is substantially
similar to that of the usual braiding machine.
It has a suitable number of bobbins operated say by spur wheels and guided in
suitable slots by carriers and race-circles in the usual manner.

The threads or yarns are interlaced on a ring supported in the centre of the
apparatus and the tube or hose passes from this ring downwards.. A conoidal
funnel extends through the ring into the tube and in said funnel rotates a screw.
driven by a strap off the main shaft. The hose encircles the end of the funnel and
is evenly filled by the screw with the material supplied from a reservoir on the
machine.
The hose when ready filled can be wound upon a reel It will be seen that
the non-conducting material consists of any suitable substance enclosed in a
plaited tube.

I HANS BOLZE, doing business under the firm of H. Bolze and Co Manufacturer,
Braunschweig, Germany, residing at Hamburgerstrasse, 37 and 38 in the City of
Braunschweig, do hereby declare the nature of this Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF MATERIAL. FOR PREVENTING THE TRANSMISSION OF
HEAT AND APPARATUS THEREFOR " and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
.
This Invention relates to the manufacture of a tube-like insulating material
intended chiefly for enveloping cold conduits or pipes. The manufacture is effected
by plaiting (by means of a plaiting or braiding machine) a dense hollow tube or
hose and evenly filling the same simultaneously with its manufacture with an
insulating material such as kieselguhr powdered cork, ashes or paper.
To this end the tube is plaited over a ring in the centre whereof a funnel shaped
tube is provided the lower end of which extends into that part of the pipe or hose
that has just been filled and contains a screw for forcing the insulating material
into the hose enabling the same to leave the machine ready filled.
The insulating material may be pulverulent pasty or in the state of a pulp.
In the accompanying Drawings a machine is shown suitable for manufacturing
this insulating material.
Figure 1 is a vertical section.
Figure 2 is a top view of the braiding machine.
Figure 3 plan with the race-disc or curve disc removed.
Figure 4 shows the ring over which the hose is braided; the filling funnel and
the screw.
Figure 5 is a transverse section of a piece of insulating hose embodying this
Invention.
The braiding machine is constructed substantially in the usual manner. In the
example illustrated in the Drawings it consists of 48 bobbins driven in a well
known manner by 24 toothed wheels b gearing with one another and by a like
number of discs c with cruciform slots and they follow a path consisting of two
curves which cross one another.
The cog wheels b are driven off the arbor d. To avoid interference with the
motion of one of the discs c by another these discs are alternately placed at a
different height.
The interlacing of the strands f of the bobbins a equally progressing half of their
number towards the right, half towards the left is effected on a ring r carried by
suitable supports 9 centrally above the bobbins the hose as made passes over the
innor edge of the ring and down through the machine.
Through the ring r the funnel T of conoidal form passes its end extending into
the tubular braid or hose H. In the funnel rotates the screw a driven by a belt h
off the arbor d it uniformly and continuously fills the hose H which is drawn
sufficiently tight over the funnel point with the insulating material. The latter is
supplied in suitable quantity to the reservoir B mounted on the framework of the
machine and above the funnel T.
The finished insulating material that is to say the hose H filled with an insulating.
substance may be wound on a reel below the machine. The insulating material
herein described formed by surrounding an insulating material with plait or braid
if compared with tubes or hose formed from woven fabric by sewing and filled

page_text: through slots at the side, offers the advantage that it better and more closely
adapts itself to the object to be insulated as the braided tubes or hose are more
flexible than those of woven fabric.
The product is moreover more uniform and close and its manufacture is extremely
simple and cheap.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is,
.
1. An insulating or non-conducting material consisting of a tubular plaited or
braided envelope H which whilst it is being manufactured is filled with an
insulating or non-conducting substance.
2. In a plaiting or braiding machine the combination of the plaiting ring r
with a filling funnel T having a screw 8, for manufacturing the insulating or
non-conducting material.
