PURPOSE:To simplify constitution, by a method wherein, in a title device for a molded material, e.g. lenses, a discharge pipe and a branch pipe, separated from each other in an up state, are connected to the tapered-off bottom of a material reserving tank having a size larger than the diameter of a material feed pipe to form a distributor. CONSTITUTION:A branch pipe 1c and a discharge pipe 1d are connected, in a state to be upwardly separated from each other, to a tapered-off bottom part 1a of a material reserving tank body 1. The branch pipe 1c is connected to a material receiving hopper 3 of a molder D. The discharge pipe 1d is connected to an input pipe 1b of a distributor A at a subsequent stage. In this way, connection in a multistage to an air suction device C is effected. In this constitution, a material fed through the input pipe 1b to the material reserving tank body 1 is naturally dropped from the tapered-off bottom part 1a to a short pipe 1e. In this case, since the branch pipe 1c and the discharge pipe 1d are both risen, a naturally dropping material is prevented from jumping up and entering a pipe on the reserve side. This constitution eliminates the need for a valve body and the like, and enables simplification of constitution.
