ABSTRACT A process for laminating discrete sections of a supported photosensitive layer to a sheet substrate comprises advancing the substrate through a nip between converging surfaces of opposed heated application rolls together with a continuous length of the supported photosensitive layer. The advance of the substrate is interrupted when it reaches a first location between the application rolls as is the supply of the photosensitive layer. The converging surfaces of each of the application rolls are moved from an inactive disengaged position transversely toward the substrate to an active position to cause pressure contact between the photosensitive layer and the substrate whereby the photosensitive layer is laminated to the substrate. The substrate is again advanced with the application rolls in active position and the supple of the photosensitive layer resumed. The disclosed process avoids localized poor adhesion and the known problems stemming from that condition.
