Device for aligning sheets with articulated arm bearing

Abstract

The invention relates to a device (60) for aligning sheets (6), especially sheets made from paper, cardboards or paperboard. The device comprises an alignment device (61) and drive (63) associated with the alignment device (61), wherein the alignment device (61) is movable in the circumferential (U), side (S) and oblique (D) directions, used for aligning a sheet (6) in the circumferential (U), side (S) and oblique (D) directions, and provided with at least one holding member for holding said sheet (6); and the drive (63) is used for enabling the alignment device (61) to move in the circumferential (U), side (S) and oblique (D) directions. According to the invention, at least a two-part articulated arm (64) is provided for supporting the alignment device (61). Advantageously, the device (60) allows a simple, low-cost and high-durability supporting.

Description

technical field

[0001] The invention relates to a device for orienting a sheet-shaped element according to the preamble of claim 1 . Background technique

[0002] The cutting of a cutting die in a closed geometric shape is called die cutting, and the cutting die can be circular, oval or polygonal and any form of irregular shape. Processing carried out in post-press, such as die-cutting with punches, corner cutting and index die-cutting also falls within this sector. Die-cutting is performed against a die-cutting block or against a punch, and is partly also a shearing process. Packaging materials made of plastic, foil material, paper, cardboard, cardboard or corrugated paper are die-cut mainly in sheet format. However, corrugations or crowns can also be additionally applied to the useful part during the die-cutting process. This complex process makes it absolutely necessary that the sheets are individually die-cut. Since the final product is a packaging that is extremely ...
