Claims

[Claims for Utility Model Registration] 1. Supplying a foamable thermoplastic resin to a resin channel of a covering mold, extruding the resin from an extrusion port at the end of the channel and foaming the resin, and at the same time inserting a core material into the covering mold. In an apparatus for supplying core material and moving a through-hole for transferring the core material in the resin extrusion direction to cover the entire surface of the core material with the resin, the resin passage is axially moved at least at the extrusion port and the vicinity thereof. A device for covering a core material with a thermoplastic resin foam, which is composed of a plurality of holes and is equipped with a sizing mold near the extrusion port. 2. The device according to claim 1, wherein the plurality of holes are provided at equal intervals on a circumference concentric with the core material transfer through hole. 3. The device according to claim 2, wherein the concentric circles formed by the plurality of holes are a plurality of circles having different diameters.
