Abstract
Gather-stitcher machine for joining and stapling a plurality of stacks of sheets of a magazine, and method for producing a thumb-tab index on magazines to be stapled by means of the gather-stitcher machine. In order to make it possible for a thumb-tab index to be machine-produced on the magazine which has been assembled together by the gather-stitcher machine, the machine is equipped with at least edge punching device arranged to the rear of a feeder guide mechanism in the transport mechanism's direction of travel, which device only produces punched-out portions in said stack of sheets in the long edges therein once the latter has been deposited.
Claims22
Gather-stitcher machine for joining and binding, or rather stapling, a plurality of stacks of sheets of a printed or other publication, in particular a magazine, having a transport mechanism and feeder guide mechanisms for depositing the stacks of sheets onto the transport mechanism,
- characterised by at least one edge punching device (23) disposed to the rear of a feeder guide mechanism (21) in the direction of travel (22) of the transport mechanism (17).
Method for producing a thumb-tab index on printed or other publications, in particular magazines, that are to be bound, or rather stapled, by means of a gather-stitcher machine, the method comprising the following steps:
- a) depositing a stack of sheets (16a) consisting of at least a single signature onto a transfer and/or processing mechanism (17) of the gather-stitcher machine (15);
- b) producing first punched-out portions (13) on at least one long edge (11) of the stack of sheets (16a) by means of an edge punching device (23) arranged to the rear of the deposition point (21a) of the stack of sheets (16a) in the conveying direction (22) of the transport mechanism (17);
- c) depositing a further stack of sheets (16b) onto the stack of sheets earlier provided with punched-out portions and lying on the transport mechanism, and producing additional punched-out portions (13) on only the signatures of the additional stack of sheets (16b), which additional punched-out portions (13) are offset in the longitudinal direction of the stacks (16a, b) with respect to the punched-out portions (13) in the stack of sheets (16a) lying underneath;
- d) if appropriate, repeating step c) of the method until the desired number of index tabs is obtained;
- e) finishing the printed or other publication by depositing additional unpunched stacks of sheets and/or stapling together the stacks lying on top of one another.
