It is an object of the present invention to uniformly disperse fibrous material such as short glass fibers so as to be distributed on a collection conveyor, without using compressed air for dispersion of the fibrous material. The present invention provides a method for collecting fibrous material, wherein the fibrous material fiberized by a spinner of a fiberizing unit is dispersed by a hollow bucket disposed just under the spinner, so as to be collected on a collection conveyor disposed below the hollow bucket, comprising:

Method and apparatus for collecting fibrous material

A method for distributing fibrous material, wherein fibrous material, which is fiberized by a spinner of a fiberizing unit, is accumulated on a collection conveyor disposed under the spinner, is characterized by rotatably disposing a hollow cylindrical bucket at a position just under the spinner, the hollow cylindrical bucket having a two-stage structure comprising an upper stage part and a lower stage part, the lower stage part being inclined at an angle with respect to a rotary axis of the hollow cylindrical bucket; and rotating the hollow cylindrical bucket, dispersing the fibrous material in the hollow cylindrical bucket and accumulating the fibrous material on the collection conveyor after flowing down the fibrous material in the hollow cylindrical bucket.

Method and apparatus for distributing fibrous material

A long-fiber-reinforced thermoplastic resin sheet comprises short strands, each of which has a width of from 0.2 to 5 mm and a length of from 10 to 150 mm and is made of a unidirectionally long-fiber-reinforced thermoplastic resin. The short strands are oriented at random and are fixed together at intersections thereof. The long-fiber-reinforced thermoplastic resin sheet has a basis weight of from 30 to 500 g/mand is provided with openings therein. The long-fiber-reinforced thermoplastic resin sheet can be produced by evenly spreading and piling up short strands of substantially circular or elliptical sections, and subjecting the short strands to pressureless hot-melt adhesion or to hot-melt compression bonding under pressure such that the sheet has a basis weight of from 30 to 500 g/mand is provided with openings therein. The short strands of the substantially circular or elliptical sections have an average diameter of from 0.1 to 1.5 mm and an average length of from 10 to 150 mm, and are made of a unidirectionally long-fiber-reinforced thermoplastic resin.
