DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method of and a device for mounting transparencies in split-frame transparency mounts or transparency mounts consisting of two frame parts.
Heretofore, if a known apparatus is used for mounting transparencies in transparency mounts, the film has been driven in guides by a conveying means, such as a roller having projections or a gripper, to be conveyed to a cutting means located in a predetermined position relative to said guides, said film has thereafter been cut view by view and each film portion so cut has been conveyed by a suction gripper or a mechanical gripper along a predetermined path to its final position in an open mount held in a holding device, as, for example, described and claimed in German Patent No. 19 18 970. Another known transparency mounting device provides for the film portion to be mounted to be driven into a frame or mount partly held open, to be cut from the film outside said frame or mount and to be moved into its final position in said mount or frame by a gripping means holding each film portion so cut through the window of said mount or frame. All known methods of and devices for mounting transparencies feature guides and cutting means attached thereto being in a predetermined position relative to the mounts or frames presented by a holding device. Such known transparency mounting devices and methods require, for the reliable transfer of the cut film portion from the cut position to the final position in the mount or transparency, the use of an additional gripping device forming an essential part of the apparatus for mounting transparencies and making the operation of feeding said cut film portion into the open mount or frame ready for framing a discontinuous operation undesirably slowing down the mounting process.
Moreover, conventional mechanical methods of and devices for mounting transparencies in transparency mounts heretofore known are unfit for handling short films and mounting the last view on such short films or require considerable manual intervention for such handling or mounting operations, the main reasons being that said last view cannot be held adequately by the guides guiding the film and cannot be moved by the conveying means of such conventional apparatus to a position suitable for said last view to be gripped by the gripping device provided.
The main object of the present invention is the provision of a novel method of and apparatus for mounting transparencies in transparency mounts allowing a reliable automatic transfer of each film view to be so mounted into its final position in said mount and holding said view therein without the use of a separate gripping device. It is another objective of the present invention to transfer each view to be mounted in each such transparency mount reliably to its final position in such mount or frame practically irrespective of the remaining length of the film being conveyed and fed by the guides provided. According to the present invention, a split-frame mount or a mount consisting of two frame parts is provided and kept open for mounting the transparency, the leading end of a developed film being moved into said open frame until the front view or front portion to be mounted has reached its final position in said mount or frame whereupon said view is fixed inside said frame. A cutting means is thereafter moved into said open mount or frame and said view being in its final position in said mount or frame is then cut from said film along a cutting line inside the open frame. The cutting means is thereafter moved out of the open frame or mount, the cut view being held inside said mount or frame, and the mount or frame is thereupon closed over said cut view still being in its final position inside said mount or frame.
The present invention hence abandons the conventional approach of known methods of and devices for mounting transparencies in transparency mounts whereby the position of the cutting device connected to the guides relative to the device holding the frames or mounts or the frames o
