Abstract

An apparatus for vibrating and dewebbing tire cord fabric treated with a liquid bonding agent for promoting the adhesion between the warp cords of the fabric and the rubbery material in which the cords are embedded. The fabric, freshly coated with the liquid bonding agent, is guided along a desired vertical pathway between a pair of rotating cylindrically shaped cams which are eccentrically mounted for rotation about axes which are equally spaced from the pathway of the fabric. The rotation of the cams is synchronized such that the cams continuously contact the fabric as they alternately push the fabric in opposite directions from the desired pathway to vibrate the fabric between the rotational axes of the cams. Thus, excess liquid coating is shaken from the fabric to help remove any liquid coating webbing the openings between the warp cords and weft threads of the fabric.

Dependent claims

An apparatus for shaking fabric coated with an undried liquid, comprising in combination:

a. means for guiding a sheet of fabric along a desired pathway which is angularly disposed to the horizontal;
b. a pair of elongated cams disposed in spaced relation, the length of each cam being at least coextensive with the width of the fabric;
c. means for mounting the cams for rotation about parallel axes which are parallel to the desired pathway of the fabric and spaced apart both in horizontal and vertical directions;
d. means for positioning the cams such that their rotational axes are equally spaced in opposite directions from the desired pathway of the fabric;
and
e. means fo 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 alternately push the fabric in opposite directions from the desired pathway, thereby vibrating or shaking the fabric between the rotational axes of the cams.
