Abstract

Abstract The present invention relates to a method for mounting bundles of perforated paper sheets between two perforated file covers, and a device for carrying out said method. The method is characterized by first fixing one cover panel of the file in position between guide means and then fixing the bundle of papers by at least two guide pins in positions such that one side, having at least two free holes, overlaps the perforated back portion of the file cover panel with said free holes coinciding with corresponding holes in the file cover panel. The other file cover panel is then placed on top of the sheet bundles in a position corresponding with the first file cover panel. Finally, retaining means are inserted into the free holes and the guide pins are removed. The device is chiefly characterized by a mounting plate having guide structures for fixing a perforated file cover panel in such a position that at least each outermost hole in the spine portion of the cover is located opposite its respective recess in the plate, at least one row of holes spaced raltive to the holes in the bundle of paper sheets being so arranged in the plate relative to the recesses that the bundle of sheets can be fixed by means of two guide pins capable of being passed through the holes in the sheets and holes in the plate so that at least two free holes in one side of the bundle of paper sheets coincides with the holes of the fil cover panel located opposite the recesses.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 147 words
A device for mounting bundles of perforated paper sheets between two perforated file cover panels, characterized by a mounting plate having guide structures for fixing a perforated file cover panel in a position such that at least each outermost hole in the spine portion of the cover is located opposite its respective recess in the plate, wherein at least one row of holes spaced in corresponding relationship to the holes in the bundle of paper sheets is so arranged in the plate in relation to the recesses that the bundle of sheets can be fixed by means of two guide pins capable of being passed through the holes in the sheets and holes in the plate in a manner whereby at least two free holes in one side of the bundle of paper sheets coincides with the holes of the file cover panel located opposite the recesses.
Claim 2
Independent Claim 147 words
A device for mounting bundles of perforated paper sheets between two perforated file cover panels, characterized by a mounting plate having guide structures for fixing a perforated file cover panel in a position such that at least each outermost hole in the spine portion of the cover is located opposite its respective recess in the plate, wherein at least one row of holes spaced in corresponding relationship to the holes in the bundle of paper sheets is so arranged in the plate in relation to the recesses that the bundle of sheets can be fixed by means of two guide pins capable of being passed through the holes in the sheets and holes in the plate in a manner whereby at least two free holes in one side of the bundle of paper sheets coincides with the holes of the file cover panel located opposite the recesses.
Claim 3
Dependent Claim 58 words
A device according to claim 1, characterized in that a first row of holes in the plate extends between the recesses, the plate being arranged to accommodate that bundle of paper sheets on one side of the row of holes, and wherein the guide means for the file cover panel can be adjustably arranged on the opposite side.
Claim 4
Dependent Claim 37 words
A device according to claim 2, characterized in that further rows of holes are arranged at a distance from each other perpendicular to and on the side of the first row of holes opposite the guide means.
Claim 5
Dependent Claim 82 words
A device according to claim 3, characterized in that an end portion of the first row of holes and a portion of at least one of the further row of holes extending perpendicular to said first row of holes is arranged in a portion of the plate which can be moved in the longitudinal direction of the first row of holes relative to the remaining portion of the plate, and which movable portion of the plate can be locked in selected positions.
Claim 6
Dependent Claim 33 words
A device according to claim 4, characterized in that the movable portion of the plate is provided with a recess at each end of the end portion of the first row of holes.
Claim 7
Dependent Claim 29 words
A device according to claim 4, characterized in that the portion of the first row of holes located on the stationary plate portion is located on an exchangeable slide.
Claim 8
Dependent Claim 31 words
A device according to claim 1, characterized in that the portion of the guide pins intended to be inserted in the holes of the plate have an outwardly tapering cross section.
