Quire-forming method and paper-folding machine

Abstract

While conveying paper, the paper is folded in a first folding pattern at right angles to the conveyance direction (S1). By bending and rupturing the folded paper, one or multiple perforation lines corresponding to a second folding pattern that is at right angles to the fold(s) are formed in the paper (S2). While conveying the paper with perforations in a direction at right angles to the previous conveyance direction, the paper is folded in the second folding pattern along the perforations, thereby forming a quire (S3).

Description

technical field [0001] The present invention relates to a method of forming a quire in which paper is folded in a first folding pattern in a direction at right angles to the direction of conveyance while being conveyed, and to a paper folding machine suitable for carrying out the method The folded paper is conveyed in a direction perpendicular to the previous conveying direction while the folded paper is folded in a second folding mode in a direction at right angles to the folding line to form a fold. Background technique [0002] As a folding machine for folding, for example, a buckle folding unit is connected with other buckle folding units at right angles to the rear section of a buckle folding unit, which is known by those skilled in the art. familiar. [0003] In this paper folding machine, after the paper is folded in a predetermined first folding mode (only mountain fold (or valley fold), or a combined structure of mountain fold and valley fold) by the barrier foldin...

Problems solved by technology

[0016] However, in the case of producing multiple types of folding sheets in small batches, in terms of manufacturing cost and production efficiency, it is not allowed to discard the corresponding folding sheets and adjust the folding unit every time a corner is generated.
