Abstract (en)

A technique of manufacturing a high-quality glass chopped strand mat (particularly, a lightweight glass chopped strand mat) which is applicable to a molded ceiling material for recent cars which have excellent design and a reduced weight, is established. A method for manufacturing a glass chopped strand mat by shaping, into a sheet, glass chopped strand (S) obtained by cutting a glass fiber (F), includes a distribution and putting step of distributing and putting the glass chopped strands (S) while allowing the glass chopped strands (S) to fall in a chamber (10), and an adjustment step of adjusting a state of the falling glass chopped strands (S). The chamber (10) includes a plurality of supply units (20) for supplying the glass chopped strands (S), and a partition member (2) for separating the plurality of supply units (20) from each other. The adjustment step is performed so that the glass chopped strands (S) do not contact the partition member (2) when the glass chopped strands (S) are falling.
