Abstract

An apparatus for manufacturing a glass fiber chopped strand mat is disclosed, in which the dropping direction of chopped strands is detected at all times, so that whenever the dropping direction is varied, immediately the relative position of an axis of a feed roller and an axis of a cutter roller with respect to a stationary structure is displaced so as to correct the dropping direction thereby to uniformly accumulate the chopped strands on a conveyer means.
