AI Technical Summary
Technical Problem
Existing technologies struggle to maintain high production speeds while processing substrates with varying properties with high quality, especially in bag-folding processes where paper of different thicknesses is prone to folding issues.
Method used
The design employs a folding roller frame with an inclined insertion well, combined with optional inserted folding bags and sheet deflectors, to optimize the sheet folding process by adjusting the offset of the folding rollers and the inclination of the insertion well.
Benefits of technology
It enables high-quality processing of substrates with different characteristics at high productivity, reduces problems in the folding process of flake-shaped sheets, and improves the folding effect.

Abstract
The invention relates to a device for folding a sheet, comprising two folding rollers with a common folding gap having an infeed side and an outfeed side, a first insertion well with a first insertion plane for an optionally inserted folding pocket with a folding pocket opening, wherein the first insertion well is configured such that the folding pocket opening of the optionally inserted folding pocket is arranged at the infeed side of the folding gap, and a second insertion well with a second insertion plane for an optionally inserted folding pocket with a folding pocket opening. The second insertion plane is configured with an inclination relative to the first insertion plane, and the second insertion well is configured such that the folding pocket opening of the optionally inserted folding pocket is arranged at the infeed side of the folding gap. The invention also relates to a method for folding a sheet using the device.
