Abstract

A wasteless type lamination system comprises a first transfer device for transferring along a first transfer path a continuous laminate film; a cutter for cutting the continuous laminate film in a predetermined length, provided beside the first transfer path at the downstream of the first transfer device; a second transfer device for transferring along the first transfer path a cut laminate film; a film detection sensor for detecting a leading edge of the continuous laminate film, provided beside the first transfer path at the downstream of the cutter; a card transfer device for transferring a card along a second transfer path; and a thermocompression bonding device for laminating the cut laminate film to the card. The continuous laminate film is moved backward from the cutter by a predetermined distance by the first transfer device before or after cutting action of the cutter.

Claims

1. A wasteless type lamination system comprising:

a first transfer means for transferring along a first transfer path a continuous laminate film with a heat adhesive layer on a surface and drawn out from a supply roll;

a cutting means for cutting said continuous laminate film in a predetermined length, provided beside said first transfer path at the downstream of said first transfer means;

a second transfer means for further transferring along said first transfer path a cut laminate film in said predetermined length;

a film detection means for detecting a leading edge of said continuous laminate film, provided beside said first transfer path at the downstream of said cutting means;

a card transfer means for transferring a card along a second transfer path that converges with said first transfer path at a point of convergence; and

a thermocompression bonding means for laminating said cut laminate film, laid on a surface of said card transferred, to said card, provided at the downstream of said point of convergence,

wherein said continuous laminate film is moved backward, in the direction upstream of said cutting means, by a predetermined distance, by said first transfer means before or after cutting action of said cutting means.
