ABSTRACT:
A type carrier belt formed into an endless loop comprising at least one elastomeric band having a trapezoidal cross-section and a plurality of interchangeable type segments snap-fitted onto the band in a side-by-side manner. Each of the segments has a flat back surface forming the radially inner surface of the belt loop, tapered leading and trailing edge portions adapted to enable said belt loop to be rotatably driven, and an indicia-bearing outer peripheral portion. The outer portion includes at least two raised pedestal portions each having an outer surface parallel to the back surface and adapted to position an indicia thereon and a dove tail-shaped slot disposed between the pedestal portions for receivably retaining the band therein. The indicia may be adapted to form alpha-numeric characters or to act as timing marks or both types may be employed on the different pedestals if desired.
