Title: Die for forming extruded shape having high fin
Inventor: SUGIO EIJI
IPC: B21C23/10
Filed: 1987-05-27
Abstract: PURPOSE:To improve the accuracy in a product and to reduce the cost by providing plural thin projections for a fin forming inside a die, arranging the bridge for reinforcing the projection by stepping over all the projection as well and linking the bridge and each projection in zigzags. CONSTITUTION:A thin projection 5 is provided in plural pieces inside a die main body 3, a narrow hole 4a for forming a high fin is formed and a wide hole 4b for forming a thick shape main body is arranged. Two projection reinforcing bridges 7 are then arranged in parallel in the form of stepping over the right and left projections 5 on the wall face at a heated billet flowing side of the die main body 3. In this case, the intermediate part of the projection 5 and the projection opposing part of the bridge 7 are linked in zigzags by a linking part 8. The breakdown of the projection 5 and the lateral fall of the bridge 7 and linking part 8 are thus prevented surely. Consequently the accuracy of a product shape is improved and the die service life is extended, hence the cost of product is reduced.

Title: Production of antistatic sized glass fiber, antistatic roving, fibrous substance for reinforcing resin and sheet molding compound
Inventor: TSUGE TOSHIO
IPC: C08J5/24
Filed: 1988-05-31
Abstract: PURPOSE:To contrive both reduction in amount of an antistatic agent used and prevention of a strand from coloring, by applying an antistatic agent or further a lubricant to the surface of a glass fiber bundle, prepared by applying a sizing agent without containing any antistatic agent to glass fibers and sizing the glass fibers. CONSTITUTION:A sizing agent without containing any antistatic agent is applied to glass fibers and sizing thereof in a required number is carried out to form a strand, which is preferably dried. An antistatic agent is then applied to the surface thereof by a method for spraying a solution containing the antistatic agent thereon, etc. Thereby, sufficient antistatic effects are obtained by using a small amount of the antistatic agent and coloring in drying the strand while heating can be prevented. Since the antistatic agent is applied separately from the sizing agent, various antistatic agents can be used without limiting the kind of usable agents in relation to the sizing agent. Furthermore, reaction of the antistatic agents with additives in the sizing agent can be prevented to improve resin impregnating ability in using the strand as a reinforcing material.
