"Process and device for the production of, Relief embossing and coloring of the embossing for wooden objects "

Tools and other utensils often own Wooden handles. To increase the grip, it is known to provide these with relief embossing, whereby these mostly experience an additional coloring. Waaen thereby these operations carried out separately from each other / whereby in particular the latter is mostly done by hand

will. This is labor and time consuming.

The invention is based on the object of a method and specify a device for the production of relief embossing, which enables such operations to be carried out in the shortest possible time and without any significant amount of work allows.

The invention relates to a method for producing Embossing in relief and practicing embossing on wooden objects and consists in the fact that the wooden objects in one of the embossed items of at least two Pormteile existing form are used, a tape provided with the color pattern to be transferred from flexible Material, in particular made of a film, through the molded parts above the wooden object used out and then adjusted the molded parts under pressure against each other and at least that bearing the embossing Part is heated.

The invention also relates to a device for implementation of the procedure. The device is characterized by that a press has a heatable mold half on its head and the other mold half is slidably mounted on the press table and between the two mold halves a sample to be transferred or the drawing to be transferred having molding tape is passed. At least one of the mold halves is expedient with an elastic one Insert. In addition, the press table can in the direction

Patent Attorney Dr. W. Andrejewskl, Dr. M. Honk ·, 43 Esten, Kettwiger StraBe

on the press head, in particular via a hydraulic one Lifting device, be adjustable. According to a particular proposal of the invention, the press table is orthogonal to the closing direction of the press, in particular via a hydraulic one Adjusting device, adjustable. This makes it easier to insert the wooden objects. Particularly beneficial is an embodiment in which the ribbon is on a drive is connected and via this step-by-step by the length of a pattern or one on the ribbon provided drawing is adjustable. The ribbon expediently consists of a stretchable material.

The advantages achieved by the invention are primarily to be seen in the fact that the relief embossing and coloring are practical can be carried out by machine in one operation and, in particular, the provided samples or drawings Transferred to the wooden object in a well-defined whiteness.

In the following, the invention is explained in more detail with the aid of a drawing showing only one exemplary embodiment; show it:

Fig * 1 shows a device according to the invention in perspective,

Fig. 2 shows a section from the enlarged scale The object according to FIG. 1 in side view, partially in section, in the area of the molded parts,

3 and 4 show a wooden object before and after treatment by the device according to the invention.

Referring to Figures 1 through 4 of the drawing, there is the device according to the invention from a mechanical press 1 of known design, in which structural changes have been made on the usual press table 2 * which in this case is flexible instead of rigid, in such a way, that he his horizontal position elastically by means of an oil dynamic or air-pressurized servomotor 3 *, which is arranged below the press table, can change, which is provided with a horizontally reciprocable table top 4 in the direction of arrow E, which by means of known and for the sake of clarity not shown means is adjustable.

Both on the punch 5 of the press head 6 of the press and on the plate 4 of the press table there are plates 7 » 8 for cementing the mold halves 9 and 10, with a heater for the mold halves 9 and 10 being provided in the plate 7, with the plate 7 a heater for the mold half 9 made of electrical resistors or the like is embedded.

The mold half 9 has such a shaped recess C, that the wooden object P to be provided with embossing or corrugation F can be accommodated therein, including the shape has engravings corresponding to the design or pattern of the embossing to be pressed in.

The lower mold half 10 is with one of the recess C. the upper mold half provided corresponding recess, the is shaped to match the middle and lower profile ·.

of the HLzartikel P fits, this recess with a elastic layer or an elastic insert made of rubber or similar material is lined with a corresponding Having thickness.

In order to also have a coloring, in the manner of gilding, at the same time as the embossing or corrugation Z on the wooden object P To carry out silver plating or the like, a device for pressing on is acting between the mold halves of a colored coating directly on the embossing intended.

This device has two pairs of roller sets 11 and 12 as well as a spool 13 for unwinding and a spool 14 for rolling up a ribbon B for embossing. These roll sets and the winding spool sit on a Konsde ΐβ, on which the associated drive parts driven by the press 1 are provided, the translations as known per se are not shown.

The ribbon B consists of a thin foil 19. » which on one side with gold, silver or other coloring Pigments 18 is splashed or coated. The ribbon can optionally be used on the uncoated side one or more plastic strips 20 be reinforced so that when the relief is embossed on the wooden object P the tape is not damaged or tears due to the pressure.

The device also has a number of electrical or pneumatic organs for running the work cycle, such as

Patent attorneys Dr. W. Andrejewski, Dr. M. Honke, 43 Essen, Ketfwiger Strasse

further described in more detail on: these organs as well as the circuits are not shown in detail, as they each Are known to those skilled in the art.

The working cycle is as follows: in the press 1, the wooden objects P (e.g. brush handles) already pre-treated or pre-painted for the embossing or fluting, the Ink ribbon 8 is fed from and to reels 13 over rollers 11 and 12 in a straight line and step by step under the mold halves 9 and guided over the mold half 10, and when a button is pressed, the press starts up; the table top 4, in the recess of which a brush handle P has been inserted is moved under the press head in a straight line 6 out, wherein the mold half 10 is arranged below the upper mold half 9, resulting in a predetermined pause occurs, for example by a delay switch, during which the mold half 9 is lowered and the embossing or the corrugation on the upper surface of the wooden object P makes while at the same time the embossing pressure during a predetermined period of time, which is also controlled by a delay switch. Then the Mold half 9 w3ä3er lifted upwards, with their adjustment distance is limited by means of a limit switch, while on the other hand the kinematic-mechanical Control comes into effect to remove the tabletop 4 from the To move out table 2 of the press and the ribbon is fed step-by-step by one step, whereupon it is ready for the next operation.
