The invention relates to a device for hot stamping emer writing or the like in conical workpieces, with one that can be pressed into the workpiece Tool and a workpiece holder carrying the workpiece, with between tool and Workpiece holder a hot stamping foil is arranged

A known hot stamping device of this type (Magazine »Kunststoffe« 2/1963, p. 168 to 170) is designed with a turntable as a workpiece holder, which is used, like a rotating magazine, to convey the workpieces that can be inserted outside of a lowerable punch serving as a tool to the embossing station and after they have been placed on and Lifting the tool to bring it to an Entnalunstelle. The workpiece stands still during the embossing process quiet; the lowered die is adapted to the workpiece surface and leads to full With the press position at rest, the inscription of the workpiece is carried out using the hot stamping foil placed in between. In another embodiment this The embossing device is the embossing stamp both

una UCiU um m «uumvi * ■» .. «..— _o however, a non-rotatable tool can roll against its embossing surface.

According to a further development of the invention, for this purpose the rolling device has a conical friction surface that can be rolled on a friction surface of the tool. For the same and predetermined attachment of a label, lettering or the like. On the. Workpieces, such as knobs, toggles, etc., are the same starting point for the beginning to comply with the imprint. In a further development according to the invention, full revolutions of the Turntable by means of a fixed microswitch and a cooperating with this, on the Turntable arranged stop controllable.

Since the rolling device can be moved deviating from a full revolution during an embossing process is, an automatic return of the rolling device to a defined starting position is useful. According to a further embodiment of the Invention achieved in that the center of gravity of the rolling device is outside its axis of rotation

located.

Another advantageous embodiment of the invention is achieved in that on the turntable a stop device is provided which has a pawl which can be deflected in one direction by the rolling device and a stop pin which inhibits its countermovement.

The invention is explained in more detail below with reference to an exemplary embodiment shown in the figures explained

Fig. 1 shows a section of a device for hot stamping and

2 shows a plan view of the device according to Fig. 1 with the rolling device removed.

The device shown for hot stamping a lettering or the like in conical workpieces is suitable for installation in known hot stamping machines, which are designed as hot stamping dies Tool 1 can be raised hydraulically or pneumatically and lowered to stamp a workpiece 2, wherein between the aut of the embossing surface 3 of the tool 1 arranged lettering unwound Od. Like. And the conical surface 4 of the workpiece 2 to be printed, a hot stamping foil 5 is provided To accommodate the workpiece 2, in the example a toggle switch is provided, a rolling device is used 6, which is rotatably arranged with its pin 7 in an ao Lager8, the axis of rotation 9 of The workpiece and the rolling device run through the center of the lowered tool as The head part of the rolling device 6, formed by the workpiece holder, rolls with the conical friction surface 10 on as a friction surface 11 of the tool 1 from when the bearing block 12 carrying the bearing 8 is with a driven turntable 13 rotates with the bearing block 12 with the bearing 8 is eccentric on the
