1. A laminator, comprising:
a substrate supply part for supplying a substrate on which a metal pattern is formed for each predetermined unit area;
a coverlay supply part for supplying a film to which a plurality of coverlays punched to a predetermined size is attached;
a heating roller part for bonding the substrate and the film so that the plurality of coverlays respectively covers the metal pattern;
a substrate tension adjustment part for adjusting tension of the substrate transferred to the heating roller part;
a film tension adjustment part for adjusting the tension of the film transferred to the heating roller part;
a bonding state image photographing part for measuring an interval between the plurality of coverlays after the heating roller part bonds bonding the substrate and the film; and
an adjustment part for adjusting any one or more of the tension of the substrate adjusted by the substrate tension adjustment part and the tension of the film adjusted by the film tension adjustment part so that the interval between the plurality of coverlays measured by the bonding state image photographing part maintains a preset allowable interval,
wherein the heating roller part includes:
a pair of first heating rollers opposite to both surfaces of the substrate; and
a pair of second heating rollers opposite to both surfaces of the substrate, located behind the pair of first heating rollers to secondarily heat the substrate and the film primarily heated by the pair of first heating rollers, and
wherein the bonding state image photographing part includes:
a first bonding state image photographing part for measuring an interval between the plurality of coverlays in the substrate and the film bonded by the pair of first heating rollers; and
a second bonding state image photographing part for measuring an interval between the plurality of coverlays in the substrate and the film bonded by the pair of second heating rollers.
