Apparatus for vibrating and dewebbing tire cord fabric coated with an undried liquid

Claim 3

The apparatus of claim 1, wherein each of the cams is cylindrical, and the rotational axis of each cam is eccentric in relation to the longitudinal axis of the cam.

Claim 4

The apparatus of claim 1, wherein the fabric contacting surfaces of the cams are composed of stainless steel.

Claim 5

The apparatus of claim 1, wherein the cams are rotated, in unison, in opposite directions at from 500 to 5000 revolutions per minute.

Claim 6

The apparatus of claim 1, which includes a housing surrounding the cams for containing liquid coating shaken from the fabric.

Claim 7

The apparatus of claim 1, wherein the housing includes a pair of curved scraper blades for contacting opposing sides of the fabric in vertically spaced relation.

Claim 8

The apparatus of claim 1, wherein each of the cams has an elliptical cross-section taken in a plane normal to the longitudinal axis of the cam.

Claim 9

The appartus of claim 7, wherein the rotational axis of each cam coincides with the longitudinal axis of the cam, the longitudinal axes being at the intersection of planes containing the major and minor axes of the elliptically shaped cams.

Claim 10

The apparatus of claim 8, wherein the fabric contacting surfaces of the cams are composed of stainless steel.

Claim 11

In combination: a. a dip tank containing a liquid coating including a bonding agent for promoting the bond between fabric and rubbery material in which the fabric is embedded; b. means for directing a sheet of fabric into the liquid coating in the dip tank; c. means for guiding the fabric from the dip tank in a desired pathway which is angularly disposed to the horizontal; d. an elongated cam positioned on either side of the desired pathway of the fabric immediately above the dip tank, the cams being spaced apart both in a vertical and horizontal direction; e. means for mounting the cams for rotation about parallel axes which parallel the desired pathway of the fabric; f. means for positioning the cams such that the rotational axes thereof are equally spaced from the desired pathway of the fabric; and g. means for synchronizing rotation of the cams such that I. the outer surface farthest from the rotational axis of one of the cams and the outer surface closest to the rotational axis of the other of the cams, simultaneously contact the fabric and Ii. the cams continuously contact the fabric as they push the fabric in opposite directions from the desired pathway of the cord, thereby vibrating the fabric between the rotational axes of the cams.

Claim 12

In combination: a. a dip tank containing a liquid coating including a bonding agent for promoting the bond between fabric and rubbery material in which the fabric is embedded; b. means for directing a sheet of fabric into the liquid coating in the dip tank; c. means for guiding the fabric from the dip tank in a desired pathway which is angularly disposed to the horizontal; d. an elongated cam positioned on either side of the desired pathway of the fabric immediately above the dip tank, the cams being spaced apart both in a vertical and horizontal direction; e. means for mounting the cams for rotation about parallel axes which parallel the desired pathway of the fabric; f. means for positioning the cams such that the rotational axes thereof are equally spaced from the desired pathway of the fabric; and g. means for synchronizing rotation of the cams such that I. the outer surface farthest from the rotational axis of one of the cams and the outer surface closest to the rotational axis of the other of the cams, simultaneously contact the fabric and Ii. the cams continuously contact the fabric as they push the fabric in opposite directions from the desired pathway of the cord, thereby vibrating the fabric between the rotational axes of the cams.

Claim 13

The combination of claim 10, wherein each of the cams is cylindrical and eccentrically mounted for rotation about a rotational axis which parallels the longitudinal axis thereof.

Claim 14

The combination of claim 11, which includes a housing at least partially surrounding the cams for directing liquid coating shaken from the fabric back into the dip tank.

Claim 15

The combination of claim 12, wherein the housing includes a pair of curved scraper blades for contacting opposing sides of the fabric, the width of each scraper blade being at least coextensive with the width of the fabric.

Claim 16

The combination of claim 12, wherein the outer cylindrical surfaces of the cams are composed of stainless steel.

Claim 17

The combination of claim 12, wherein the cams are rotated, in unison, in opposite directions which are opposed to the direction in which the fabric moves past the cams.
