ABSTRACT:
Economical and trouble-free operation of automatic processing machines for webs such as photographic film strips and paper is achieved.
A leader tape is threaded through the processing machine. The leading end of a strip of film or paper to be processed is automatically attached to this tape for transport through the machine. Behind the attachment point of the strip to the transport tape, the tape is automatically severed, but is later automatically reattached to the trailing end of the strip. This operation is repeated for consecutive film strips or papers to be processed through the machine.
In this way, an uninterrupted band of either tape or web is always in the machine. This permits simple machine construction, with supports for the web preferably only at its turnabout locations, and with powered drive preferably only at the exit from the machine. Yet, even long webs of film or paper can be automatically processed without wasteful leader tape consumption.
