Abstract

A process for developing a photosensitive material, and a device therefor, are disclosed wherein an image on a photosensitive material consisting of a cover base laminated through the intermediary of a photosensitive layer to a support member is developed into a visible image by stripping the cover base from the support member. A preliminary stripping step of stripping the cover base from the support member in the leading end portion thereof is first performed. This is immediately followed by the reorientation of the leading end portion of the cover base to bring the same into registration with the support member. Therefore, a final stripping step is performed wherein the cover base is successively separated from the leading end portion thereof towards the trailing end thereof from the support member.

Dependent claims

A stripping and developing process for a photosensitive material consisting of a cover base laminated through the intermediary of a photosensitive layer to a support member, wherein the cover base is stripped from the support member thereby providing a visible image on the support member, said stripping and developing comprising the steps of

a preliminary stripping step of stripping said cover base from said support member in the leading end portion of said photosensitive material, said stripping being due to friction in a direction opposite to an advancing direction of said photosensitive material, followed by the reorientation of the leading end portion of said cover base to the advancing direction of said photosensitive material, thereby bringing the leading end portion of said cover base into registration with said support member, wherein the reorientation of the leading end portion of said cover base to the advancing direction of said photosensitive material is accomplished by friction in the direction of the advancing direction of said photosensitive material, and
a final stripping step of stripping said cover base of said photosensitive material after said preliminary stripping step first from the leading end portion thereof successively towards the trailing end thereof, whereby the cover base is completely separated from the support member.

A stripping and developing device for a photosensitive material consisting of a cover base laminated through the intermediary of a photosensitive layer to a support member, wherein the cover base is stripped from the support member thereby providing a visible image on the support member, said stripping and developing device comprising:

means for preliminarily stripping said cover base from said support member in the leading end portion of said photosensitive material, said stripping being due to friction in a direction opposite to an advancing direction of said photosensitive material, and for thereafter reorientating the leading end portion of said cover base to the advancing direction of said photosensitive material, thereby bringing the leading end portion of said cover base into registration with said support member, wherein the reorientation of the leading end portion of said cover base to the advancing direction of said photosensitive material is accomplished by friction in the direction of the advancing direction of said photosensitive material, and
means for finally stripping said cover base of said photosensitive material by separating and clamping the leading end portion of said cover base and thereafter separating said cover base from the leading end portion towards the trailing end thereof from said support member.
