Embodiment Construction

[0022]The invention relates to the field of print further processing. Here, these are devices such as collating machines, adhesive binders or cover feeders. FIG. 1 shows a part of a collating machine 10 in simplified form, namely only one feed station 11 of the collating machine 10 is shown. The feed station 11 has a magazine 12 for accommodating a stack 13 of signatures which lie one above the other, which are folded sheets 14 in the present case. The folded sheets 14 of the stack 13 are separated in the region of the feed station 11, by a lowermost folded sheet 14 being pulled off from under the magazine 12 gradually.

[0023]The respectively lowermost folded sheet 14 of the stack 13 is separated in a first step by the apparatus according to the invention which is configured as a tilting sucker 15 in the collating machine 10 which is shown here. An edge region 16 (it also being possible for it to be only a corner region) of the lowermost folded sheet 14 is tilted away from the stack ...

Abstract

An apparatus for tilting away a part of a sheet to be separated, in which apparatus a compressed-air supply is sufficient for operating the tilting sucker. To this end, the tilting sucker of the apparatus is assigned a vacuum generator which can be fed with compressed air and which generates a vacuum from the supplied compressed air.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The invention relates to an apparatus for tilting away a part of a signature to be separated from a stack, having at least one sucker which is arranged on a carrier and can be moved, preferably pivoted, by the carrier for tilting away a part of the signature to be separated, and having at least one supply channel in the carrier for supplying the respective sucker with vacuum.[0003]2. Prior Art[0004]In the print further processing of signatures such as individual sheets, covers or quires, individual signatures are to be pulled off from a stack of signatures. In the separation of the signatures which occurs in this way, first of all a part of the signature to be separated, in particular an edge strip or a corner region, is tilted away with respect to the stack. An apparatus of the type which is addressed here serves for this purpose, which apparatus is also known briefly as a tilting sucker in the specialist language.[0005]An ap...
