More Information
Summary:The invention relates to a binder material activating device (10) to activate a binder material (18) on a fibrous substrate (14), the binder material activating device (10) comprising a heat exposing device (20) to expose the fibrous substrate (14) with the binder material (18) to heat. The heat exposing device (20) comprises a non-focused light source (22) to provide a non-focused light beam (12) and an optics device (28) to be arranged in between the fibrous substrate (14) to be exposed to heat and the light source (22) to focus the non-focused light beam (12) onto the fibrous substrate (14). Further, the invention relates to a preforming device (40) comprising the binder material activating device (10).
