Abstract: The invention relates to a device and to a method for producing containers (2) such as bottles or drums, using preforms (3) preferably made of plastic, including the steps of supplying preforms (3), pre-heating the performs (3) by radiation in a heating module (5), and stretching and/or blowing the performs (3) by a blower (7), characterised in that the radiation has a wavelength between 1.5 ?m and 2 ?m and a device (1) for the production of containers (2) such as bottles or drums, using performs (3) preferably made of plastic, including a preform (3) conveyor (4), a heating module (5) including infrared emitters (6) and a bottle blower (7). The radiation has an emission peak corresponding to a wavelength between 1.7 ?m and 5 ?m, and the metal filament has an emission surface such that the ratio of the emitter input power to the filament emission surface is between 0.080 and 0.250 W/mm2.

Abstract: A device for diverting sheet, web or mat material treated continuously uses an air cushion (6) formed about a cylindrical surface (4). Infrared transmitters (7), whose radiation is directed to a portion of the material (1) being diverted, are provided in or under the cylindrical surface (4), in addition to the air-blowing means (5) generating the air cushion (6). The same volume therefore houses means for diverting the material (1) and means for heating it, especially in order to dry it. At the same time that the blown air flow generates the air cushion (6), it also cools the infrared transmitters (7). Application, in particular, in the manufacture, transformation and treatment of materials such paper, fabric and synthetic film.
