Embodiment Construction

[0026] figure 1 Shown is a sheet folder 100 with a sheet feeder 10 , a supply station 20 , a fence folding station 30 and a signature collector 40 . In the region of the sheet feeder 10 , the respective sheets 1000 are separated from the sheet stack 1001 and passed on to the supply station 20 . The corresponding sheet 1000 is fed from the feeding station 20 to the fence folding station 30 along the sheet transport direction T. FIG. In this case, the processing of the sheet 1000 can take place via the upstream knife spindle 31 in order to prepare the crease. In the fence folding station, the actual processing, ie folding of the sheet 1000 , takes place via the interaction of the folding fence 33 with the folding rollers 32 . The structure of the fence-type folding station 30 will be further described below according to additional drawings. The sheets 1000 that have been folded in the fence folding station 30 are set as signatures 1002 in the signature collector 40 .

Abstract

The invention relates to a fence type folding station and a pages fold machine. The fence type folding station is provided with at least one folding fence and a plurality of folding rollers for folding page-shaped elements, wherein a respective folding fence is provided with an upper guiding surface and a lower guiding surface, the corresponding page-shaped elements enter and leave the space between the upper guiding surface and the lower guiding surface, and the lower guiding surface is provided with a lower lip arranged on the end part of the folding roller side and used for guiding the corresponding page-shaped elements to enter and leave the folding fence. According to the invention, the lower guiding surface is provided with at least one support element, and at least folding roller is provided with at least one bearing element on the peripheral region, wherein the support element is supported on the bearing element. In this way, an advantageous manner is adopted to substantially reduce the bending of the lower lip, to substantially improve page guiding and further to improve the folding quality.

Description

technical field [0001] The invention relates to a fence folding station with the features according to the preamble of claim 1 and to a sheet folding machine according to claim 10 . Background technique [0002] Barrel folding machines and knife folding machines are known from the prior art. A combination of a fence folder and a knife folder is popular as a hybrid folder. Here, the parallel folds are folded in a fence folding device and the crossing folds are folded in a subsequent knife folding device. In this case, the sheets pass through at least the following stations in the direction of travel of the hybrid folder: feeder, transfer table, fence folding mechanism, knife folding mechanism, collector. [0003] DE 10 2004 041 471 A1 discloses the construction of a fence folding machine with a plurality of fence folding mechanisms. In this case, each fence-type folding mechanism comprises a folding fence and three folding rollers, which are arranged as two folding roller ...
