3 Claims. (01. 91-31) Our invention relates to fabric coating machines and particularly to machines for coating cord fabrics with arubber solution, such fabrics being used in vehicle tires.

The object of the invention is to improve the eiliciency of such machines and ,to remedy the delffcts experienced in previous machines of this so Fig. 1 shows a cross-section of our machine,

and

Fig. 2 shows a modification. Referring to Fig. 1, the chamber A is open at the top and bottom and has sides Al and A2. It-

is supported on a frame above a trough Al containing the rubber solution. A roll 6 dips into the rubber solution in the tank and carries the fabric into and out of the tank. Located above the roll 6 is a guide roll which guides the fabric from the chamber to the roll 6.

Above the chamber is a guide roll I, which is so positioned with relation to the guide roll 5, that the entering dry cloth, which passes over guide roll I from a source of supply, is held in contact with the outside surfaces of'the rolls 2, l and l which are arranged vertically above one another in the chamber. Locatedin the chamber opposite the spaces between rolls and 3 and between 3 and 4 are rolls 1 and 8. The rolls are so related to one another that the dry cloth passes down. in contact with the outside surfaces of rolls 2, I and 4, and, after passing through the solution and arounddip roll 8, the wet cloth passes upwards in contact with the inside surfaces of and preferably are about 4 to 6 in. in diameter,

are of polished steel and are rotated at high speed, by any suitable means, not shown, so that they thus have a surface speed of about to 30 ft. per

I second, preferably in the direction of the feed'of ary. Thus the machine enables high production .efliciency and low production cost to be attained.

rolls 8 and l, the cloth being carried, as shown, about the rolls 5, a, b, c and d.

The cloth is pulled through the apparatus b any suitable means, not shown. a

By means of this arrangement, one or both sets of burnishing rolls are cleaned by the ingoingfabric and the eflicient removal of excess solution from the fabric is achieved and consequently a solution of higher solids content may be employed than has been the previous practice and because of the low moisture content in the fabric a higher drying speed may be used than has been custom- We claim:

1. A fabric coating machinehaving in combination a chamber open at top and bottom and having vertical sides, two sets of burnishing rolls therein, said rolls being rotated with a surface speed of from 15 to 30 feet per} second, the rolls in each set being in alignment with each other. a tank located below said chamber and adapted to contain a rubber solution, a roll dipping into said tank, means to guide the incoming dry fabric against the sides of the rolls of one set with which sides the wet fabric does not contact and means to guide the wet fabric against the opposite sides of said rolls and against the other set of rolls in said chamber.

2. In fabric coating apparatushaving a tank for holding a coating solution and opposed sets of burnishing rolls for removing excess solution coated on fabric passed through the tank, in combination, guide rolls for directing a fabric from a the cloth. The rolls, due to their high surface 4 speed burnish the cloth and eifectively remove excess solution from the surfaces of the cloth and from the fabric, to the incoming cloth which wipes these rolls and: keeps them in a clean condition whereby their efllciency in removing excess solution from the fabric is greatly enhanced.

In the apparatus of Fig. 2, the incoming cloth wipes not only the rolls 2, I and l, but also the source oi! supply through the tank, and thence between and against opposed faces of the burnishing rolls, including guides directing the fabric, prior to its passage through the tank, against and across the outside faces of the burnishing rolls of at least one set.

3. In fabric coating apparatus having a tank for holding a coating solution and opposed sets of burnishing rolls for removing excess solution coated'on fabric passed through the tank, in combination, guide rolls for directing a fabric from a source of supply through the tank, and thence between and against opposed faces of the burnishing rolls, including guide rolls directing the fabric, prior to its passage through the tank,

against and across the outside faces of both sets of the burnishing rolls.
