Embodiment Construction

[0027] figure 1 A schematic diagram of a flatbed die cutter 100 according to the present invention is shown. The illustrated embodiment of the flatbed die-cutter 100 is modularly constructed in a horizontal configuration. In this schematic illustration, the processing of the printed material web 24 (such as folding boxes printed on a cardboard web in the previous rotary printing press 8) proceeds from right to left: from the web supply device 14, the printed material web The belt 24 reaches a flat-bed die-cutting station and / or an embossing station (hereinafter referred to as flat-bed die-cutting station 12) along the web running direction B, in which the The stroke movement H of the lower platen 28 towards the upper platen 26 causes the printing material web 24 to be cut into such that in a subsequent processing step individual printed products (eg folding box blanks) can be cut out of the printing material web 24 and separated from each other. Instead of or in addition to...

Abstract

The invention relates to a method for register correction of a flatbed punch and / or embossing machine (100), wherein by measuring the corresponding printed image (25) and Registration of / or the punched image (29) and / or the embossed image and / or the grooved image enables determination of register deviations and correction paths (k) for compensating for register deviations. For this purpose, shortened or overlong sheets ( 6 ) can be produced using the transverse cutter ( 10 ), which can then be ejected. Advantageously, the method according to the invention for register correction carries out a register correction very quickly, and only a small number of waste pages are generated. The invention also relates to a flatbed punch and / or embossing machine (100) for carrying out the method.

Description

technical field [0001] The invention relates to a method for register correction of a flat-bed die-cutter and / or embossing machine and to a flat-bed die-cutter and / or embossing machine. Background technique [0002] Die-cutting is described as the cutting out of a cut-out shape with a geometry that is closed in itself, which can be circular, oval or polygonal as well as all types of imaginary shapes. Said die-cutting takes place towards the die-cutting mat or towards the punch, partly also a shearing process. Packaging materials formed from plastics, film material, paper, cardboard, cardboard or corrugated cardboard are die-cut mainly in sheet format and also in web format. During the die-cutting process, it is also possible to additionally emboss groove lines or Import the application. Because the final product involves packaging that is demanding in terms of technical and graphic implementation (special packaging for cosmetics, cigarettes, medicine, food, etc.), specia...
