Abstract
A method of removing waste material from an annular, elastomeric article 10. The method includes the steps of: securing at least a portion of the annular, elastomeric article 10; securing at least a portion of the waste material; penetrating the waste material with a cutting tool 52; and guiding the cutting tool 52 through the waste material. The method is characterized by the step of stretching the waste material prior to guiding the cutting tool 52. In the preferred method, the waste material is stretched a distance sufficient to simultaneously apply some degree of tension to the unsecured portions of the waste material.
