PROVISIONAL SPECIFICATION.
Improvements in and relating to Machines for Forming and Fixing
the Fold of Folded or Doubled Fabrics.
I, FERNAND DEHAITRE of 1 Boulevard St. Denis, Paris, France, Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
11
The machine which constitutes the subject of this invention is composed of two
hollow cylinders of sheet steel or other material heated internally by steam and
supported on suitable frames. Each cylinder is partly surrounded by an endless felt
the tension of which can be regulated as required by means of movable rollers over
which it passes.
The two cylinders are not driven directly but are drawn into rotary motion by the
friction of the endless felts; these receive their movement from rollers driven by
bevel gearing from the main shaft. The journals of the cylinders turn on rollers so
as to soften the movement and prevent slipping of the felts on the cylinders. For
some fabrics i employ in lieu of the endless felts, sheets of metal or of canvas or other
textile material.
The folded or doubled fabric is carried by one of the felts around one of the
cylinders and then by the other felt around the other cylinder, the one face of the
fubric coming in contact with the first cylinder and the other face in contact with
the second cylinder; both sides of a folded or doubled fabric can thus be finished
or calendered while the fold is being formed and fixed.
More than two hollow heated cylinders can be employed if necessary.
With the machine I combine a folding or doubling machine of any known con-
struction from which the folded or doubled fabric travels to the forming and fixing
machine above described and I actuate it by gearing from the forming and fixing
machine so that the two machines may work in unison, which is very important.
Behind the cylinders are a folder of any ordinary kind and a taking up .roller;
the folder is for folding the doubled fabric transversely into laps after it leaves the
cylinders and the taking up roller is for rolling or winding up the doubled fabric.
Either the folder or the taking up roller is used according to whether the doubled
fabric is required to be in folds or in a roll.

COMPLETE SPECIFICATION.
Improvements in and relating to Machines for Forming and Fixing
the Fold of Folded or Doubled Fabrics.
I, FERNAND DEHAÎTRE of 1 Boulevard St. Denis, Paris, France, Mechanical
Engineer, 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 machine which constitutes the subject of this invention is represented in
longitudinal elevation in Figure 1 of the annexed drawings and in plan in Figure 2,
and is composed of two hollow cylinders A and B of sheet steel or other material
heated internally by steam, and supported on suitable frames CD. Each cylinder
is partly surrounded by an endless felt E and F, the tension of which can be
regulated as required by means of movable rollers over which it passes; these rollers
are lettered GHIJKLM and N.

page_text: The two cylinders A and B are not driven directly but are drawn into rotary
motion by the friction of the endless felts these receive their movement from
rollers OP driven by bevel gearing Q and frictional gearing V from the main shaft.
The journals of the cylinders A and B turn on roller bearings at R and S so as to
soften the movement and prevent slipping of the felts on the cylinders. For some
fabrics I employ in lieu of the endless felts, sheets of metal or of canvas or other
textile material.
.
The folded or doubled fabric is carried by the felt E around the cylinder A and
then by the other felt around the other cylinder B, the one face of the fabric
coming in contact with the first cylinder and the other face in contact with the
second cylinder; both sides of a folded or doubled fabric can thus be finished or
calendered while the fold is being formed and fixed.
More than two hollow heated cylinders can be employed if necessary.
With the machine I combine a folding or doubling machine of any known con-
struction such for example as is shown at X from which the folded or doubled fabric
travels to the forming and fixing machine above described and I actuate it by
gearing from the forming and fixing machine so that the two machines may work
in unison which is very important.
Behind the cylinders A and B I show a folder T of any ordinary kind and a
taking up roller U; the folder is for folding the doubled fabric transversely into
laps after it leaves the cylinders, and the taking up roller is for rolling or winding
up the doubled fabric. Either the folder or the taking up roller is used according
to whether the doubled fabric is required to be in folds or in a roll.
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 :-
1. The machine hereinbefore described for forming and fixing the fold of folded
or doubled fabrics, the said machine comprising two or more hollow steam heated
cylinders, not driven directly' but caused to rotate by the friction of endless felts or
fabrics which pass round then as set forth.
2. The combination with the machine referred to in Claim 1 of a folding or doubling
machine, the two machines being driven by gearing the one from the other so that
they shall work in unison, as herein before described.
