ABSTRACT OF THE DISCLOSURE An improved method is provided for making a hickey roller. It includes the first step of providing an elastomeric matrix material having elongated substantially parallel fibers therein, supporting the elastomeric matrix material on a cylindrical support to define a roller having a longitudinal axis and having an outer tubular portion, the supporting step also serving to arrange the fibers approximately parallel to the longitudinal axis; the second step of curing the outer portion in a moisture-free environment to define a cured elastomeric matrix having the fibers embedded therein with each fiber having a cohesive strength which is greater than the cohesive strength of the elastomeric matrix and each of the fibers also having a cohesive strength which is greater than the adhesive force holding each fiber in said elastomeric matrix; the third step of machining the outer portion to remove elastomeric matrix from and thereby to expose portions of the fibers which are arranged radially outwardly of a cylindrical surface defined by machining while radially inwardly arranged portions of the fibers are held inwardly of the cylindrical surface by the elastomeric matrix. By these steps, the exposed outer portions of the fibers extend outwardly from the cylindrical surface to define a brush-like construction for the hickey roller. The machining step results in comparatively large increments of the exposed outer portions of the fibers being engaged and temporarily moved transverse the longitudinal axis in a non-shearing manner due in large measure to the fibers having the cohesive strength which is greater than the cohesive strength of the elastomeric matrix, the exposed outer portions returning essentially to their original positions following the machining step to define the brush-like construction. Thus a hickey roller is provided which removes hickeys from printing plates, without absorbing an excessive amount of ink, and which is easy to clean and maintain.
