发明名称 Method of making paint roller bearings
摘要 An open and shut molding method of making a paint roller bearing with offsetting core support surface for use in paint roller applicators that permit the user to change a paint roller quickly and efficiently on a paint roller applicator by bringing together a first mold and a second mold until a portion of the molds contact each other to thereby provide central regions in the mold cavity to exclude moldable material therefrom and then flowing a moldable plastic material into the mold cavity formed between the first mold and the second mold and separating the first mold from the second mold to enable removable of a ready to use molded one piece paint roller bearing housing having a central opening extending therethrough for inserting of a shaft therein for rotatable supporting the ready to use paint roller bearing housing thereon.
