Claims13
A method for marking batches in a continuously produced sheet corresponding to different batches of raw elastomeric material in a sheet, wherein the method comprises steps of:
- continuously producing a sheet in a longitudinal direction;
- providing the sheet with a series of different batch markings, wherein each different batch marking is unique to a respective sheet batch, wherein a series of batch markings are provided intermittently at a regular interval along the longitudinal direction of the continuous sheet;
- and
- providing a start or end marking indicating the start or end, respectively, of a respective sheet batch in response to a switchover to a new batch of raw elastomeric material.
