DEFINITION

Classification: 242/554.4

Differentiated material portion (e.g., material end, tear, or signal):

(under subclass 554) Subject matter wherein the automated control is adapted to detect a particular characteristic or condition in the elongated material and initiate the splicing operation in response to the characteristic or condition.

(1) Note. The characteristic can be a control signal, a tear or other intentional or accidental imperfection in the material, while the condition can be a highly tensioned segment of material, a break, expiration of the material, or other prevailing condition, any of which initiate the start of the splice including simply stopping the unwinding so that the splice can be performed.
