Abstract
In a lamination system for laminating a film with a heat adhesive layer on at least a surface of a plastic card applying heat and pressure by heat rollers, each of two rectification devices for rectifying warp in the laminated card is provided independently of each other, at the downstream of the heat rollers, respectively along each of sides of the card along card transfer direction. Each of the rectification devices comprises a pair of rotatable rollers.
Claims3
A lamination system having a thermocompression bonding means for laminating a laminate film with a heat adhesive layer on at least a surface of a card made of a plastic material by applying heat and pressure by heat rollers;
- wherein two rectification means for rectifying warp in said card are provided independently of each other, downstream of said thermocompression bonding means, respectively along each side of said card along a card transfer direction, said two rectification means capable of being displaced independently of each other along a plane transverse to the direction of travel of the card and fixed in place, each of said rectification means comprising a pair of opposing rotatable rollers, with said opposing pairs of rollers each adapted to engage opposite edges of said card as said card travels along said card transfer direction.
