DEFINITION

Classification: 242/331

Intermediate storage (e.g., low inertia bin):

(under subclass 324) Subject matter comprising a buffer zone specifically provided for temporarily storing a length of information-bearing carrier between the supply coil and take-up coil, which length is significantly greater than the distance taken along a normal carrier path.

(1) Note. A buffer zone accommodates a low inertia reserve length of a carrier during periods of rapid carrier acceleration to avoid excessive carrier stress, or at times when driven components may not be in precise harmony.
