Patented Oct, 8, 1929 -Jaime WILLIAM arm, or unsure, GERMANY CARD CLOTH HAVING A FELT LAYER Application filed September 12, 1927, Serial No. 219,062, and. in Germany April 19, 1927.
The present invention relatesto card cloths having a felt layer.
The known card cloths provided with a felt layer have the disadvantage that the cards obtained by means of this cloth are easily damaged in use and therefore do not usually last long. I
A considerable amount of fibrous material adheres to the rough felt surface and, on cleaning the card, partial brushing out of the felt layer of the card cloth along with the adherent threads cannot lac-avoided so that the felt layer soon becomes thin and non-uniform. The resistance of the card wires consequently drops-since on decrease in thickness of the card cloth only a shorter end of the legs of the card wires is led into the cloth. F inally after a short time the operation of the card wires also leaves something to be desired since each leg of the card wires on moving to and .fro impresses a slit like depression in the felt layer in which it oscillates to and fro without the resilient felt mass-acting on the wire.
It has accordingly already been proposed to glue a thin sheet "of pure rubber, cut in the cold, on to the felt layer as a protective coating. A rubber layer of this type is however very sensitive and easily pulls away on stripping with the hand card so that shreds of the rubber layer are pulled out along with portions of the felt. Also the protective layer of rubber dissolves on the action of oil and is not reliable in the sun and heat. Finally the flat smooth coating of rubber adheres badly to the felt layer.
These disadvantages existing in card cloths 'havin a felt la er are avoided accordin to it: b
the invention by mounting a covering layer of vulcanized rubber on the felt layer and se- 4 curing this thereto by means of a layer of thread as resilient as possible, for example,
a loose or porous cotton cloth.
The vulcanization of a rubber layer on the felt layer of the card cloth is impossible in view of the animal substances contained in the felt. The layer of thread provided according to the invention, for example a loose or porous cotton cloth, under the covering layer allows of a layer of vulcanized rubber being applied to the card cloth with the felt "of thread. This fabric layer allows of a se- .of the card cloth with a felt layer. Cards pretion. A vulcanized rubber layer 3 which is Ilaayer instead of the known cover of pure rub- The method adopted according to the invention is to mount the rubber firston a fabric layer preferably cotton, and to vulcaniz e it thereon, the covering layer so obtained being I then secured to the felt layer by means of a solution of rubber, cement or other adhesive.
The fabric layer, which on vulcanization, acts as a support for the rubber mass and is united with the latter, should be as resilient as possible so as' to reduce the elasticity of the rubber layer as little as possible by the layer cure union between the rubberand the felt layer on gluing the fabric layer supporting the vulcanized rubber on to the felt layer, so that a surprising adherence of the whole covering layeris obtained which is essentially greater than that of, a simple layer of nonvulcanized rubber.
The'improved card cloth having a felt layer and covering layer of vulcanized rubber possesses to-a greater degree the advantages pared therefrom are accordingly more suitable than cards bf the known card cloths with unprotected thicker layers'of milled woolen felt, particularly for spinning wool and similar purposes. The thin card cloths provided with vulcanized rubber layers hitherto known which consistedsolely of woven fabric could on the other hand, only be used for preparing cards for cotton spinning.
The feltlayer in the improved card cloth can exert its favourable action on the movement of the card wires permanently without damaging this layer in any way on cleaning. The vulcanized rubber layer is itself extraordinarily resistant to damage, adheres firmly to the felt layer and is not dissolved or injured by oil and heat. Further, less fibrous material adheres to the smooth rubber surfaceof the card cloth than felt surface.
A section of a card cloth on the fabric base 1 of which is arranged a felt layer 2,-in the usual manner is shown in Fig. 1 of thedrawings as a form of construction of the inven- I vulcanized on a fabric layer 4 is glued to this felt layer as a covering layer. The fabric layer -1- produces a secure union between the covering layer 3 and the felt layer 2.
Figure 2 is a cross section through the improved card cloth showing the improved arrangement of the separate layers in card cloths provided with a felt layer.
I declare that What I claim is 1.. A card cloth consisting of a fabric base and a felt layer cemented to the said fabric base and provided with a covering layer of loose cotton cloth cemented to the felt and having a previously vulcanized layer of rubber.
2. A method of producing a card cloth consisting of-mounting a layer of felt on a fabric base, coating a loose cottfoncloth with a layer of vulcanizable rubber, vulcanizing said layer of rubber and then fastening the said cotton cloth to the layer of felt by means of an adhesive substance.
In testimony whereof, I have signed my name to this specification at Leipzig, Germany, this 18th day of August, 1927.
