First Claim
Patent Images
1. A production line for producing sheets based on hydraulic binder from a preform, comprising:
- in an upstream zone of the production line, a marking device for marking a facing material of the preform with a mark;
in a downstream zone of the production line, a detecting device for detecting the mark made by the marking device;
a cutting device;
an actuating device for actuating said cutting device after receiving a detection signal from the detecting device;
an additional detecting device for detecting the mark so that the mark is detected at least twice;
a device for making an impression in the preform; and
an additional actuating device for actuating said device for making an impression in the preform after receiving a detection signal from the additional detecting device, whereinthe mark is distinct from the impression.

19. A production line for producing sheets based on hydraulic binder from a preform, comprising:
-
in an upstream zone of the production line, a marking device for marking a facing material of the preform with a mark; in a downstream zone of the production line, a detecting device for detecting the mark made by the marking device; a cutting device; an actuating device for actuating said cutting device after receiving a detection signal from the detecting device; an additional detecting device for detecting the mark; a device for making an impression in the preform; and an additional actuating device for actuating said device for making an impression in the preform after receiving a detection signal from the additional detecting device, wherein the device for making an impression in the preform comprises an upper forming plate and a lower forming plate between which the preform and at least one wire pass, and the at least one wire makes the impression by accompanying the preform between the forming plates, after which the device for making the impression separates the at least one wire from the preform from above the preform.
