ABSTRACT:
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 includes 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, and an outlet region through which energy may be transported in the direction of the burr. 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. Infrared radiation emitted by the energy source is concentrated by a radiation-forming element, so that only the burr is irradiated by the infrared radiation. The radiation-forming element may be formed by a gap in the outer coating.
