Abstract
Abstract Method and device for stapling stacks of sheets situated in bins placed one above another in parallel with a stapler movable along the bins, the stapler being rotatable about an axis of rotation so as to move the stapler at each bin from an inoperative position, in which the stapler is turned away from the bins, to an operative position, in which the stapling elements of the stapler surround an edge portion of the stack of sheets to be stapled, the stapler having a pressure surface which, during this rotatory movement, pushes to one side of an adjacent bin a stack of sheets already stapled and positioned in the adjacent bin.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
An apparatus for stapling stacks of sheets in parallel bins, comprising: a plurality of bins having a surface for storing stacks of sheets, and a stapler movable in a vertical direction with respect to said bins to a position adjacent to two of said bins, said stapler at said adjacent position being rotatable about an axis perpendicular to said surface of said bins between an inoperative position and an operative position, said stapler being provided with a pressure surface such that when said stapler is in said operative position, a stack of sheets in one of said adjacent bins is displaced by said pressure surface in a direction along said bin surface while a stack of sheets in the other of said adjacent bins is stapled by said stapler.
Claim 2
Independent Claim
129 words
An apparatus for stapling stacks of sheets in parallel bins, comprising: a plurality of bins having a surface for storing stacks of sheets, and a stapler movable in a vertical direction with respect to said bins to a position adjacent to two of said bins, said stapler at said adjacent position being rotatable about an axis perpendicular to said surface of said bins between an inoperative position and an operative position, said stapler being provided with a pressure surface such that when said stapler is in said operative position, a stack of sheets in one of said adjacent bins is displaced by said pressure surface in a direction along said bin surface while a stack of sheets in the other of said adjacent bins is stapled by said stapler.
Claim 3
Dependent Claim
36 words
An apparatus in accordance with claim 1, wherein said stapler, when in its inoperative position, is situated, seen in a direction transverse to said direction of displacement, outside said stacks of sheets positioned in said bins.
Claim 4
Dependent Claim
21 words
An apparatus in accordance with claim 1, wherein said pressure surface forms an angle with a lateral surface of said stapler.
Claim 5
Independent Claim
96 words
An apparatus as in claims 1, 2 or 3, further including a means for applying pressure to sheets stored in said bins, said means being disposed on a side of said bins remote from that side where said pressure surface is situated in said operative position, and comprises a pressure element which is movable between a position in which said pressure element presses sheets lying in said bins against a side stop and a position in which said pressure element is free of sheets which are displaced away from said side stop by said pressure surface.
Claim 6
Independent Claim
116 words
A method of stapling stacks of sheets in parallel bins of a sheet stacking apparatus with a stapler which can be moved into a stapling position relative to each bin, the method comprising: positioning said stapler into a stapling position adjacent to two of said bins, rotating said stapler about an axis perpendicular to a sheet support surface of said bins between an inoperative position and an operative position, placing a staple in a stack of sheets in one of said adjacent bins while said stapler is in said operative position, and displacing a stack of sheets in the other of said adjacent bins along said support surface while rotating said stapler to said operative position.
Claim 7
Independent Claim
116 words
A method of stapling stacks of sheets in parallel bins of a sheet stacking apparatus with a stapler which can be moved into a stapling position relative to each bin, the method comprising: positioning said stapler into a stapling position adjacent to two of said bins, rotating said stapler about an axis perpendicular to a sheet support surface of said bins between an inoperative position and an operative position, placing a staple in a stack of sheets in one of said adjacent bins while said stapler is in said operative position, and displacing a stack of sheets in the other of said adjacent bins along said support surface while rotating said stapler to said operative position.
