Abstract
A method and apparatus for separating layers of a laminated thermographic media is disclosed. The apparatus has a torque roll cooperating with a pair of peel rolls which breaks a tab on the media without a hard stop thereby avoiding shock induced premature delamination. After the media is initially delaminated, a deflector roll operable independently of the peel rolls engages the backside of the substrate for establishing a deflector angle. An anti-skew system is also incorporated for aligning the media with the torque roll and peel rolls.
