DEVICE FOR CUTTING A SUBSTRATE LAYER, AND CORRESPONDING METHOD

摘要

The invention concerns a device for automatic high-precision cutting of a material layer (20a) which is integral with a source substrate (20b) via a weakened zone (200c), the source substrate and the layer to be cut forming together an assembly to be cut (20), the device comprising cutting means (101, 102) as well as means for retaining (100a, 100b) the assembly to be cut. The invention is characterized in that the retaining means are designed for controlled displacement so as to accompany actively the divergence and/or the deformation of each part of the assembly to be cut, and to rectify said divergence and/or said deformation. The invention also concerns a corresponding automatic cutting method.
