Abstract:
1. A device for removing an oblong burr from a molded part including an energy source that introduces energy into the burr for removing the burr by heating, the energy source comprising: an infrared transmitter that irradiates the oblong burr with infrared radiation, a sleeve for receiving the infrared transmitter with an inner face facing the infrared transmitter and an outer face remote from the infrared transmitter, wherein the sleeve has an outer coating with a surface facing the outside, and an inner face facing the infrared transmitter which at least partially encloses the sleeve, and an outlet region through which energy may be transported in the direction of the burr, wherein the outlet region is formed by a gap in the outer coating that is of oblong configuration such that it may be arranged along the oblong burr following a path of the burr; wherein infrared radiation emitted by the energy source is concentrated by a radiation-forming element, such that only the burr is irradiated by the infrared radiation, and the radiation-forming element is formed by the gap in the outer coating.
