Abstract
A system and method (10) for heating objects (O) during a thermal treatment process in a production line (P) is described. The system (10) comprises a transport system (11), a minor arrangement (201, 202, 203, 204, 205, 206) comprising a first mirror surface (21, 21′, 21″) and a second minor surface (22, 22′, 22″) arranged at opposite sides, so that the objects (O) may be transported between the minor surfaces (21, 22, 21′, 22′, 21″, 22″) along the production line and a radiation device (30) comprising a number of lasers for generating light (L). The radiation device (30) and the mirror arrangement (201, 202, 203, 204, 205, 206) are constructed such that the main direction (R) of light (L) that enters the mirror arrangement (201, 202, 203, 204, 205, 206) is directed towards the first mirror surface (21, 21′, 21″) at an angle to the production line (P), and the light (L) subsequently undergoes multiple reflections between the mirror surfaces (21, 22, 21′, 22′, 21″, 22″) so that a series of multiple reflections of the light (L) travels in the transport direction (OT) along at least a section of the minor surface (21, 22, 21′, 22′, 21″, 22″) or travels against the transport direction (OT) along at least a section of the minor surface (21, 22, 21′, 22′, 21″, 22″) and heats the objects (O) being transported between the minor surfaces (21, 22, 21′, 22′, 21″, 22″).
