To decorate boxes, boxes and the like with colored stripes on the edges, it is customary to attach the panels or discs used to make the boxes to those Mark the areas where the edges are to be formed with colored stripes.

In contrast to this, in the present invention, the ornamentation takes place Edges by applying paint directly to the finished boxes or boxes.

In the case of angular boxes, the aid in the accompanying drawing serves as an aid through Fig. 1, 2 and 3 and, in the case of round boxes, those on the accompanying drawing device illustrated by Figs.

On a horizontal shaft w , two metal disks m are slidably arranged, the circumference of which is stepped off. These disks are immersed in trays / filled with printing inks, which are carried by arms α which are attached to a rail u belonging to the frame of the device. On this work sheets b are slidably attached, the ends of which are cut out so that they follow the profile of the panes with little clearance. The disks are set on the shaft w so that the distance between their shoulders is equal to that of the edges of the boxes to be colored. After the shaft w has been rotated in the direction of the arrow (Fig. 2), the box is placed on the discs and pressed against them by hand so that it moves on them. As a result, the edges of the same in the width and height of the heel of the discs are covered with paint.
■ In a somewhat expanded form, such a device can be used to apply paint to the edge and edge of round box halves. A workpiece holder ρ is then added, which enables the edge of the round box to be pressed against the disc m which emits the paint. For this purpose, the workpiece holder consists of a sliding pin in a koulissenartigen frame \ with rod s which passes through the upper part of the frame, k terminates in a push button and is below the same / surrounded by a coil spring. A washer g is screwed against one end face of this pin, the shape of which corresponds to the clear cross section of the box half at its edge. The workpiece holder is attached to the device described in such a way that the disk g is in the same vertical plane as the step on the disk m (see FIG. 6).

The edge of the box to be decorated is placed on the pane g and then pressed against the pane m by pressing the button k . As a result of this, the rotation of the latter is transmitted to the box, so that all parts of its edge and edge come into contact with the layer of paint on the disc.

The device of Fig. 1 to 3 can also be used to the edges

Claims (3)

and to color the edges of a cardboard disc. It is then expedient to add pressure disks d as shown in FIG. 7, which stress the edges of the cardboard disk when they are placed on the dye disks and are transported by them. Patent claims: i. An apparatus for coloring the edges of boxes made of paperboard and the like., Characterized by two on a shaft (n>) displaceably arranged discs (m) with step-shaped contrasting extent that the color of them received in the Farbebehältem (I) at its rotation transferred to the edges of the cardboard box inserted under pressure between their paragraphs. 2. For coloring the edge and edges of round boxes, a device according to claim 1. in connection with a workpiece holder (pj, consisting of a disk (g) displaceable in a coulisse against spring pressure for attaching the boxes and pressing them against one of the boxes 'rbescheiben (m). 3. A device according to claim 1 in connection with printing disks (d) over the coloring disks (fn) for the purpose of coloring cardboard disks at the edges. 1 sheet of drawings.
