Improvements in Clothing for Carding Engine Cylinders and Flats,
and in Mounting the same.
I, EUGENE APPENZELLER, of the Société Anonyme Filature et Filteries
Reunies, Alost, Belgium, Cotton Spinner, do hereby declare the nature of this
invention to be as follows:-
My invention relates to card fillets for clothing cylinders and flats and in mounting
the same.
The object of my invention is to clothe the cylinders and flats in an improved
manner.
When cylinders of carding engines are clothed with card fillet there is great
difficulty in grinding the card teeth near each end of the cylinder properly because
the fillet being cut off taper where it forms the end coils gives less support to the
wire the teeth of which remain longer than the others consequently a perfect
adjustment of the carding engine is impossible and its work will be imperfect.
To remedy this I propose to increase the thickness of the foundation, which
may be of any suitable manufacture, of the card fillet for a given length about
equal to the length of a coil, at those portions of the foundations which will form
the first and last coil when wound on the cylinder to be covered. I do this
gradually and during the manufacture of the foundation or subsequently by sewing
or otherwise.
Thus for example, For a card fillet manufactured with say a three plait or fold
foundation I make a four, five or six plait or fold foundation for those portions of
the fillet which would form the first and last coil when on the cylinder. For a fillet
with a four or five plait or fold foundation I increase the thickness to six seven or
eight plaits or folds, or more if required.
By increasing the thickness of the foundation of the fillet which forms these
end coils I obtain a more solid foundation to which greater tension can be applied
thus affording greater support to the wires which will be more rigid and offer
greater resistance to the grinding roller thereby allowing them to be ground and
to wear uniformly with the rest of the card clothing on the cylinder.
When card fillet is secured on card flats in the usual manner there is great
difficulty in imparting the desired rigidity to the card teeth. To ensure this I
apply immediately under the foundation of the card fillet and between it and the
base of the card teeth or between adjoining plaits of a plaited foundation a band
of leather, artificial leather or other suitable material preferably thinner at the
edges than at the middle and about equal in width to the space covered by the card
teeth.
By this means all the card teeth bear equally on the card flat and the points of
the teeth are all properly set in the same plane after the fillet is mounted which
would not be the case if ordinary card fillet were mounted on a card flat which
was slightly crowned or raised along the middle.

Improvements in Clothing for Carding Engine Cylinders and Flats,
and in Mounting the same.
I, EUGENE APPENZELLER, of the Société Anonyme Filature et Filteries
Reunies, Alost, Belgium, Cotton Spinner, 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 :-
My invention relates to card fillets for clothing cylinders and flats and in mounting
the same.
The object of my invention is to clothe the cylinders and flats in an improved
manner.
When cylinders of carding engines are clothed with card fillet there is great
difficulty in grinding the card teeth near each end of the cylinder properly because
the fillet being cut off taper where it forms the end coils gives less support to the
wire the teeth of which remain longer than the others consequently a perfect
adjustment of the carding engine is impossible and its work will be imperfect.
To remedy this I propose to increase the thickness of the foundation, which may
be of any suitable manufacture, of the card fillet for a given length about equal
to the length of a coil, at those portions of the foundations which will form the
first and last coil when wound on the cylinder to be covered. I do this gradually
and during the manufacture of the foundation or subsequently by sewing or
otherwise.
Thus for example,-For a card fillet manufactured with say a three plait or fold
foundation I make a four, five or six plait or fold foundation for those portions of
the fillet which would form the first and last coil or more when on the cylinder.
For a fillet with a four or five plait or fold foundation 1 increase the thickness to
six seven or eight plaits or folds or more if required.
This part of my improvements is illustrated by Figs. 1 and 2 of the accompanying
sheet of drawings which views show one end of the foundation for a card cylinder
fillet.
In these views the part lettered (a) is say of five ply or fold thickness, (b) is six
ply (c) is seven ply and (d) the end section is eight ply the whole cemented together
in the usual manner.
By increasing the thickness of the foundation of the fillet which forms these end
coils I obtain a more solid foundation to which greater tension can be applied thus
affording greater support to the wires which will be more rigid and offer greater
resistance to the grinding roller thereby allowing them to be ground and to wear
uniformly with the rest of the card clothing on the cylinder.
When card fillet is secured on card flats in the usual manner there is great
difficulty in imparting the desired rigidity to the card teeth. To ensure this I
apply immediately under the foundation of the card fillet and between it and the
base of the card teeth or between adjoining plaits of a plaited foundation a band
of leather, artificial leather or other suitable material preferably thinner at the
edges than at the middle and about equal in width to the space covered by the card
teeth.
This part of my improvements is illustrated by Figs. 3 to 8.
In Figs. 3 and 4 (e) represents the flat, (f) the card fillet the foundation (¹) of
which is composed of several plies of material cemented together and (g) the layer
of material which in this case is shown about the width of the space occupied by
the card teeth, the card teeth passing also through the material (g).
In Figs. 5 and 6 in addition to the layer (9) another layer (h) of similar material
but as wide as the flat (e) is shown, the card teeth passing also through the layers (g)
and (h).
Instead of placing the material (g) below the foundation (f¹) it might be placed
above the foundation.

page_text: In Fig. 7 the layer (9) is of special shape and is fitted between the plies of the
foundation (¹) Fig. 8 shows the same rivetted to a flat (c).
By this means all the card teeth bear equally on the card flat and the points of
the teeth are all properly set in the same plane after the fillet is mounted which
would not be the case if ordinary card fillet were mounted on a card flat which was
slightly crowned or raised along the middle.
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 use and application of additional plies or folds to increase the thickness
of those portions of the fillet which form about the first and last coils or more
when on the card cylinder substantially as described and as illustrated by Figs. 1
and 2.
2. The use and application of a layer or layers of suitable material in combination
with card fillet for covering flats substantially as and for the purposes herein
described with reference to Figs. 3 to 8.
