two-piece arcuate die plate having confrontable edges mounted
in confrontation collinearly on a cylinder with segments of a
rule mounted in similar collinearity on each of the
confronting pieces of the die plate and (b) a pair of
symmetrical line-up guides allochiral in configuration with
each having a joint line coincident with the confrontable edge
of a respective piece of the die plate.

boards or plates mounted on cylinders and provided with
