Abstract
Abstract A web processing device in which a web containing a processing ingredient or solution such as a developer is brought into intimate pressure engagement with an exposed film for a predetermined time to effect processing of the film. Transport and guiding mechanisms are provided for the film and web for guiding the film and web in spaced relation through a processing station. Processing is achieved at the processing station by a member movable from a normal retracted position, in which it is out of engagement with the film and web, to a laminating position, in which it moves portions of the film and web into intimate pressure engagement for a predetermined time interval. The web and film are separated upon return of the member to its normal retracted position by the combined action of the tension on the web and the angles of approach and separation defined by the film and web when they are in pressure engagement. An auxiliary separator member may be provided movable between the film and web and across the processing station to separate the film and web.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
In a filmstrip processing device of the kind in which a filmstrip and a web carrying a processing substance are disposed in intimate pressured contact for a predetermined time to effect processing of the filmstrip, the combination comprising: means for guiding a filmstrip along a normal path; means for guiding a web carrying a processing substance along a normal path which is spaced from said normal filmstrip path; and means for selectively moving at least one of such filmstrip and web between a normal position, wherein such filmstrip and web are disposed in their respective normal paths, and a processing position, wherein such filmstrip and web are disposed in intimate pressured contact to effect processing of such filmstrip; said means for selectively moving including a filmstrip and web separator member and means for mounting said filmstrip and web separator member for movement between such filmstrip and web when disposed in intimate pressured contact.
Claim 2
Dependent Claim
153 words
In a filmstrip processing device of the kind in which a filmstrip and a web carrying a processing substance are disposed in intimate pressured contact for a predetermined time to effect processing of the filmstrip, the combination comprising: means for guiding a filmstrip along a normal path; means for guiding a web carrying a processing substance along a normal path which is spaced from said normal filmstrip path; and means for selectively moving at least one of such filmstrip and web between a normal position, wherein such filmstrip and web are disposed in their respective normal paths, and a processing position, wherein such filmstrip and web are disposed in intimate pressured contact to effect processing of such filmstrip; said means for selectively moving including a filmstrip and web separator member and means for mounting said filmstrip and web separator member for movement between such filmstrip and web when disposed in intimate pressured contact.
Claim 3
Dependent Claim
188 words
In a filmstrip processing device of the kind in which an exposed filmstrip and a web carrying a processing substance are brought into intimate pressured contact, at a processing station, for a predetermined time to effect processing of such filmstrip, the combination comprising: means for advancing, under tension, successive portions of an exposed filmstrip along a normal path which extends across said processing station; means for advancing, under tension, a web carrying a processing substance along a normal path which extends across said processing station and which is spaced from said normal filmstrip path; and means, located in said processing station, for selectively moving successive portions of at least one of such filmstrip and web between a normal position, wherein such filmstrip and web portions are respectively disposed in said normal filmstrip and web paths, and a processing position, wherein such filmstrip and web portions are disposed in intimate pressured contact to effect processing of such filmstrip; said means for selectively moving including a filmstrip and web separation roller and means for mounting said roller for movement between such filmstrip and web when disposed in intimate pressured contact.
Claim 4
Dependent Claim
188 words
In a filmstrip processing device of the kind in which an exposed filmstrip and a web carrying a processing substance are brought into intimate pressured contact, at a processing station, for a predetermined time to effect processing of such filmstrip, the combination comprising: means for advancing, under tension, successive portions of an exposed filmstrip along a normal path which extends across said processing station; means for advancing, under tension, a web carrying a processing substance along a normal path which extends across said processing station and which is spaced from said normal filmstrip path; and means, located in said processing station, for selectively moving successive portions of at least one of such filmstrip and web between a normal position, wherein such filmstrip and web portions are respectively disposed in said normal filmstrip and web paths, and a processing position, wherein such filmstrip and web portions are disposed in intimate pressured contact to effect processing of such filmstrip; said means for selectively moving including a filmstrip and web separation roller and means for mounting said roller for movement between such filmstrip and web when disposed in intimate pressured contact.
Claim 5
Dependent Claim
247 words
In a filmstrip processing device of the kind in which an exposed filmstrip and a web carrying a processing substance are brought into intimate pressured contact, at a processing station, for a predetermined time to effect processing of such filmstrip, the combination comprising: means for advancing, under tension, successive portions of an exposed filmstrip along a normal path which extends across said processing station; means for advancing, under tension, a web carrying a processing substance along a normal path which extends across said processing station and which is spaced from said normal filmstrip path; a pair of roller members; means for mounting said roller members within said processing station, in spaced relation, and in a manner such that said normal filmstrip and web paths extend between said roller members; said mounting means including means for supporting said roller members (1) for movement in a first manner respectively across said normal filmstrip and web paths for deflecting successive portions of such filmstrip and web from said normal filmstrip and web paths into intimate pressured contact with each other and (2) for movement in a second, opposite, manner respectively across said normal filmstrip and web paths for enabling such filmstrip and web, so deflected, to return from intimate pressured contact with each other to said normal filmstrip and web paths; a filmstrip and web separator member; and means for mounting said filmstrip and web separator member for movement between such filmstrip and web when disposed in intimate pressured contact.
Claim 6
Dependent Claim
247 words
In a filmstrip processing device of the kind in which an exposed filmstrip and a web carrying a processing substance are brought into intimate pressured contact, at a processing station, for a predetermined time to effect processing of such filmstrip, the combination comprising: means for advancing, under tension, successive portions of an exposed filmstrip along a normal path which extends across said processing station; means for advancing, under tension, a web carrying a processing substance along a normal path which extends across said processing station and which is spaced from said normal filmstrip path; a pair of roller members; means for mounting said roller members within said processing station, in spaced relation, and in a manner such that said normal filmstrip and web paths extend between said roller members; said mounting means including means for supporting said roller members (1) for movement in a first manner respectively across said normal filmstrip and web paths for deflecting successive portions of such filmstrip and web from said normal filmstrip and web paths into intimate pressured contact with each other and (2) for movement in a second, opposite, manner respectively across said normal filmstrip and web paths for enabling such filmstrip and web, so deflected, to return from intimate pressured contact with each other to said normal filmstrip and web paths; a filmstrip and web separator member; and means for mounting said filmstrip and web separator member for movement between such filmstrip and web when disposed in intimate pressured contact.
