    CROWING OR EMBOSSING TOOL
    The present invention relates to a creasing or embossing tool consisting of a base body made of a flat, strip-shaped material blank and one formed on one of its longitudinal edges, triangular in cross section perpendicular to its longitudinal center plane with a linear, end-formed creasing or embossing edge, which extends at least partially over the length of the base body.
    Such creasing or embossing tools are known. These known creasing and embossing tools have, inter alia, a planar working section running perpendicular to the longitudinal center plane. It has been found here that these creasing and embossing tools have a shortened service life, which is due to increased abrasion.
    The present invention is based on the object of improving the known creasing and embossing tools of the type described above in such a way that reduced abrasion and thus a longer service life are achieved.
    According to the invention this is achieved by the features of claim 1 in that the embossed edge is formed by a planar, perpendicular to the longitudinal center plane working section which merges at its longitudinal edges over an outwardly curved rounded area in the side surface of the tip. A sharp-edged transition between the working section and the side surfaces of the tip is thus avoided, so that less material deformation occurs in the area of the working section. The resulting reduced wear in the area of the working section enables a longer service life.
    According to the invention it is advantageous if the working section has a width of 0.015 mm to 0.03 mm, preferably 0.017 mm. The radius of the rounding of the two rounding areas is preferably 0.026 mm to 0.036 mm, the center point being on the longitudinal center plane.
    An interior angle enclosed by the side surfaces of the tip is preferably 15 ° to 90 °, in particular 15 ° to 70 ° and preferably 52 ° to 54 °. In particular, the interior angle can be less than or equal to 42 °. The tip is advantageously designed as a similar or isosceles triangle, specifically with respect to a section perpendicular to the longitudinal center plane.
    A tool according to the invention is advantageously produced by a machining process, for example by chasing, scraping or planing.
    A tool according to the invention is particularly suitable for processing cardboard or corrugated cardboard.
    The invention is explained in more detail using the exemplary embodiment shown in the drawings. Show it:
    1 shows a side view of a creasing or embossing tool according to the invention and
    FIG. 2 shows a cross section through a section of the tip in the area of the working surface according to the section line II-II in FIG.
    In the various figures of the drawing, the same parts are always provided with the same reference numerals.
    In the following description it is claimed that the invention is not limited to the exemplary embodiments and not to all or more features of the described feature combinations, rather each individual partial feature of the / each exemplary embodiment is also detached from all other partial features described in connection therewith for itself and also in combination with any features of another embodiment of importance for the subject matter of the invention.
    As shown in Figure 1, a creasing or embossing tool according to the invention has a base body 1 for embossing linear folding grooves or embossing grooves in materials such as cardboard or cardboard boxes, fine cardboard boxes or corrugated cardboard. The base body 1 has a grooved or embossed edge 4 on one of its longitudinal edges 2, 3, which extends at least over the entire length of the base body 1. The creased or embossed edge 4 is designed in cross section as a triangular point 5, wherein the point 5 can be designed as an isosceles or equilateral triangle. The creased or embossed edge 4 is formed by a planar working section 6 running perpendicular to the longitudinal center plane X-X, as can be seen from FIG. This working section 6 merges into the side surfaces 8, 9 formed by the tip 5 via rounded areas 7 that are curved outward.
    The working section 6 preferably has a width of 0.015 mm to 0.03 mm, preferably 0.017 mm. The two rounded areas 7 are rounded with a radius r of 0.026 mm to 0.036 mm, based on a center point M lying on the longitudinal center plane X-X.
    It is advantageous within the scope of the invention if the side surfaces 8, 9 of the tip 5 with each other enclose an interior angle of 15 ° to 90 °, in particular from 15 ° to 70 ° and preferably from 52 ° to 54 °. In particular, an interior angle of less than / equal to 42 ° is also advantageous.
    Due to the configuration according to the invention, the creasing or embossing edge 4 wears less during operation due to less abrasion and less deformation, so that overall a longer service life of the creasing or embossing tool is achieved according to the invention. The creasing or embossing tool according to the invention can be produced in one work process, in which case machining processes in particular are used; processes such as chasing, scraping or planing can be used here.
    A base body 1 used according to the invention has, for example, a thickness of 0.7 mm to 1.4 mm, in particular 1.05 mm. The base body 1 is made, for example, from steel strip, in particular from spring steel strip. In the area of its embossed edge 4, it can advantageously be hardened.
    The invention is not limited to the illustrated and described exemplary embodiments, but also includes all embodiments that have the same effect within the meaning of the invention. It is expressly emphasized that the exemplary embodiments are not limited to all features in combination; rather, each individual sub-feature can also have an inventive significance in isolation from all other sub-features. Furthermore, the invention has not yet been restricted to the combination of features defined in claim 1, but can also be defined by any other combination of specific features of all of the individual features disclosed. This means that in principle practically every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application.
