Abstract (en)

A glass chopped strand mat manufacturing apparatus is provided which can improve the production efficiency and quality of a glass chopped strand mat, particularly a lightweight one . An apparatus for manufacturing a glass chopped strand mat (M) by shaping glass chopped strands S into a sheet, includes first conveying means (50) for continuously conveying the glass chopped strands (S) in a distributed form while spraying resin powder (A) serving as a binder, and second conveying means (60) for continuously conveying the glass chopped strands (S) to which the resin powder A adheres while performing a heating treatment on the glass chopped strands (S) at a temperature higher than the melting point of the resin powder (A). The second conveying means (60) includes a plurality of rollers arranged from upstream to downstream, where a conveying direction of the glass chopped strands (S) is defined as a flow direction, and a cooling structure is provided for at least one of the plurality of rollers.
