Abstract
When producing plastic cards, a plurality of layers is laminated under application of heat and pressure resulting in unpredictable shrinking. In order to compensate shrinking, the laminated web is elongated to adapt to its nominal alignment size. Elongation is produced by material displacement along grid bars separating to-be-fabricated cards later punched off the web leaving a waste grid.
