Problems solved by technology

A disadvantage is that in the mode of operation in which the module carriers are each equipped with a single braking module, the total contact area of ​​the contact part between the braking band and the printed sheet to be braked is relatively small
Since the total contact area available for transferring the braking force from the sheet braking system to the printed sheet is so small, the amount of braking force that can be transferred is also too severely limited

Embodiment Construction

[0018] FIG. 1 shows a detail of a printing press 1 with delivery 2 . The printing press 1 is a perfecting press and is optionally operable in a pure one-sided printing job mode and a perfecting printing job mode for duplex printing of printed sheets, in which pure one-sided printing jobs In mode printing sheets are printed on only one sheet. The sheet braking system 3 and the delivery stack 4 of the delivery 2 are shown in this section. The sheet brake system 3 comprises a plurality of sheet brakes, namely a sheet brake 5a on the drive side of the printing press 1, a sheet brake 5b on the operating side and a sheet brake arranged in between them 5c. The sheet stoppers 5a to 5c have the same structure, and the number of these sheet stoppers may be four or five or more in the case of larger sheet sizes.

[0019] FIGS. 2 and 3 show that the sheet brakes 5 a to 5 c each comprise a carriage 6 on which the module carrier 8 is pivotably mounted via a hinge 7 . The module carrier ...

Abstract

The present invention relates to a sheet braking system (3) for braking printed sheets, which includes sheet arresters (5a, 5b, 5c) setting in a row. The sheet arresters comprise module carriers for carrying brake modules (10, 11). The module mountings are movably arranged on each other, and the brake modules are disconnectably formed to and from the module carriers. The brake modules (10, 11) are coupled to one of the module carriers in an operation mode.

Description

technical field [0001] The invention relates to a sheet braking system for braking printed sheets, the sheet braking system comprising sheet brakes arranged in a row, which have sheet brakes arranged displaceably relative to one another for carrying A module carrier of the braking module, the braking module being configured to be coupled and decoupled from the module carrier. Background technique [0002] Such a sheet braking system is described in DE10103235A1. In the sheet brake system of the prior art, in one mode of operation a single brake module with a brake band and in the other mode of operation a single support module with a drying wheel is carried with the corresponding module Piece coupling. Disadvantageously, in the operating mode in which the module carriers are each equipped with a single braking module, the total contact area of ​​the contact portion between the braking band and the printed sheet to be braked is relatively small. Since the total contact are...
