Abstract
Various embodiments relate to a device for the production of preforms for aircraft structural components, having a supply unit for the continuous supply of a layer structure with at least one fiber layer, having a heating unit with at least one infrared heater which has an infrared radiation source, wherein the supplied layer structure is passed through the heating unit in a conveying direction and can be heated there over at least part of its width in cross section by the at least one infrared heater, a disk which is permeable to infrared radiation being arranged between the layer structure and the infrared heater.

A device for the production of preforms for aircraft structural components, comprising a supply unit for the continuous supply of a layer structure with at least one fiber layer, having a heating unit with at least one infrared heater which has an infrared radiation source, wherein the supplied layer structure is passed through the heating unit in a conveying direction and can be heated there over at least part of its width in cross section by the at least one infrared heater, a disk which is permeable to infrared radiation being arranged between the layer structure and the infrared heater.
The device as claimed in claim 17, wherein the infrared heater comprises a particularly adjustable reflector, which is configured such that the width can be set transversely to the conveying direction, on which the infrared radiation source takes effect on the layer structure.
The device as claimed in one of the preceding claims, wherein the heating unit has at least one further infrared heater which heat the layer structure from above, and/or at least one infrared heater which heat the layer structure from below.
