ABSTRACT:
A method of making a resilient expandible inking ring by forming a ring of elastomeric ink-absorbent material of generally rectangular cross-section, seating the ring in a thin wall U-shaped shell of unvulcanized rubber leaving the outer portion of the ring outwardly to extend from the shell introducing a bonding material formed of an uncured rubber slurry between the shell and the ring and vulcanizing the assembly. The ring may be formed by end to end bonding of a strip of said ink-absorbent elastomeric material.
