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.

Method of making an inking ring

An inking ring and wheel for code daters, the ring being formed as an elongate length of ink absorbent strip material of generally rectangular cross-section arranged secured end to end to define a ring, said ring being seated in a thin wall U-shaped shell whereby the outer portion of the ring extends radially from the shell so that a portion thereof is disposed outward of the shell. Preferably, the strip is formed of foam rubber and the shell is formed of uncured rubber. A slurry of a solvent and uncured rubber is used as an adhesive for joining the ends of the strip, as well as the strip to the shell. The assembly is vulcanized to effect permanent securement. The thus formed inking ring is mounted upon a cylindrical hub and a pair of side plates retained thereon on both sides of the inking ring to define an inking wheel.
