METHOD FOR THE PRODUCTION OF HYDROPHILIC POLYMER.

摘要

Quantitatively supplying an introduced material to a subsequent stage comprises restricting the depth of a material sent along the upper surface of a transfer mechanism from an introduction end to a transfer end before the material reaches the transfer end, the upper portion of the depth-restricted material being taked out quantitatively by a raking member long enough to cut into the portion of the material, this raked-out portion of the material being discharged by the raking member as the lower portion of the depth-restricted material which is not raked out by the raking member is discharged by the transfer mechanism.
