Description
Technical field
The present invention relates to a kind of device that the laminated object that preferably moves at the compound type folding machine is positioned of being used for.
Background technology
The grid cutter folding machine of combination, promptly so-called combination folding machine is pressed the folding parallel folding line of buckle-fold principle in the first folding station, and intersection folding line is subsequently realized by the folding blade of vertical work.After parallel folding line finished, the page or leaf that is folded was opened by load-transfer device and fricton-tightly is transported to intersection folding station for this reason.In order to guarantee really fricton-tightly to carry, must compress the plane object that is transferred and it vertically is pressed on the load-transfer device.In order to produce required for this reason vertical pressure, not only use to load ball, and use guide roller.This loading ball system is for example open by German utility model DE 84 06 391.But strengthening the use of guide roller in the recent period, this for example is described among the German utility model DE 93 04 281.These guide rollers are compared with loading ball system has special advantage, for example, can reach the accurate page or leaf of track by guide roller and open guiding.
For accurately folding in knife-fold mechanism, must accurately locate the guide roller of the most close intersection folding line backstop, in other words, page or leaf is opened " freely " between preceding seamed edge backstop and guide roller.In order to guarantee this point, essential positioning and guiding roller like this, promptly this guide roller just also rotates and neither opens on the trailing edge also not directly on folding sheets at page or leaf.This device is open by German utility model file DE 299 04 757.Wherein propose a kind of device that is used to compress and load the laminated object of motion, in this device, be provided with one or more guide rollers in order to compress object.For positioning and guiding roller exactly, at least one in these guide rollers is provided with mark.
