Problems solved by technology

[0008] The disadvantage of the fence folder described above is that it can cause problems when forming the piers
If the pier is not caught quickly enough and securely by the pulling rollers, it can collide with the following sheet and thus cause a material jam

Embodiment Construction

[0039] exist figure 1 The folding device of the fence folding machine 100 is shown in FIG. 1 , as it is basically known from the prior art. The folding device comprises a first folding roller 1 , a second folding roller 1 . 1 and a third folding roller 2 . The folding rollers 1 and 1.1 together form a first pair of rollers, which is also called pair of advancing rollers. The pair of rollers 1 , 1 . 1 pushes a sheet 30 into the folding fence 6 of the folding device. The folding fence 6 has a sheet stop 6.1, which is transported up to the feed sheet stop. Here, the sheets are guided by an upper barrier lip 6.2 and a lower barrier lip 6.3. As soon as the sheet 30 touches the sheet stop 6 . A crease is formed in the sheet 30 which appears as a fold edge in the finished folded product. The rollers 1.1 and 2 thus form a folding roller pair, which is also referred to as a pulling roller pair. Said roller 1.1 thus forms a special roller with a double function, since it is not on...

Abstract

The invention relates to a method for folding applied for a buckle plate folding machine. The buckle plate folding machine has at least one first roller pair, a first later folding buckle plate at the paper running direction and a later folding roller pair at the paper running direction, wherein the the peripheral speed of one roller in the folding roller pair is always higher than the peripheral speed of of the other folding roller. A paper is drawn to pass through a folding station in a tension state through the speed difference. The invention also relates to the folding machine employing the method, wherein the application schemes of a standard rolling unit and a special rolling unit are set. According to the invention, the drive line or the folding roller diameter of the folding machine is adjusted.

Description

technical field [0001] The invention relates to a method for folding sheets as claimed in claim 1 and to a fence folder as claimed in the preamble of claims 8 or 9 or 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 passage of the hybrid folder: feeder, transfer table, fence folding device, knife folding device, delivery. [0003] DE 10 2004 041 471 A1 discloses the construction of a fence folder with several fence folders. In this case, a crease is produced in each folding device. Each fence folding device comprises a folding fence and three folding rollers arranged in two folding roller pairs. The fold...
