The present invention relates to an apparatus and method for using the excellent physical and chemical properties after the treatment playing a crosslinked polyethylene foam scrap was added to the resin mixture with sawdust and a pigment thereto to prepare a supporter one for use in semi-permanent, cross-linked polyethylene foam transferor 110 for transferring the scrap; The first extruder (120) for calculating a cross-linked regenerated raw material was granulated by melting the scrap foam supplied by the conveyor 110; The low-density polyethylene (LDPE) / ethylene-vinyl acetate input hopper 130 that supplies a resin mixture, sawdust and pigments (EVA) and; And a second extruder 140, which receives supply of a raw material of the recycled raw material, and each input hopper 130 of the first extruder (120) forming a supporter through a forming die 141 is installed at an end, but the melt / extrusion; And vacuum cooler 150 to the second extruder 140 is supplied to receive the shaped supporter through the primary cooling in vacuum; And a spray condenser (160) to the vacuum through the cooler 150 by spraying cold water on the primary cooling Secondary cooling supporter; Taking the the shaped supporter through the second extruder 140, and the odor (170) for supplying vacuum to the condenser 150; Supporters production apparatus 100 and use them with a cross-linked polyethylene foam scrap consisting of a cutter 180 for cutting the supporter 200 commercialized secondary cooling by the spray condenser 160 is finished to a size intended for use the invention relates to a method.
