Abstract

This method determines a reference lateral position of a copy (30) in a folding machine (2), the copy (30) having a given width and being delimited by a first lateral edge (44) and a second lateral edge (46), the folding machine(2) being designed to convey the copy (30) in a path and having at least two first conveying members (36) that convey the copy over a first portion of the path (32), each first conveying member (36) defining, for each of the first and second lateral edges (44, 46), a first preferred lateral zone (48). At least one of the first preferred lateral zones (48) extends laterally beyond the associated first conveying member (36) and partially laterally straddles this first conveying member (36). The reference lateral position is determined in such a way that at least the first lateral edge (44) lies inside a first preferred zone associated with this first lateral edge (44). Application to the folding machines of offset rotary presses.

Description

technical field [0001] The invention relates to a method of determining the reference lateral position of a copy (copie) having a given width and bounded by first and second sides in a folder designed to follow a path A copy is conveyed and there are at least two conveyance members conveying the copy through a first portion of the path, and each first conveyance member defines a first preferred lateral region for each of the first and second sides. Background technique [0002] From document EP-A-658 426 a method is known for determining the lateral position of copies in a folder so that the copies are not damaged when the fingers of the collating rollers grip the leading edge of the copies. Position the copy laterally so that the sides are at least half covered by the belt. [0003] However, folders have a number of conveyors arranged one behind the other in the folder and used to feed the copies through the folder. These conveyor means consist, for example, of conveyor b...
