Abstract

PURPOSE: To make no caterpillar trace leave behind on the surface material of a building plate by winding wires closely in the moving direction of a lower caterpillar over all its circumferential surface.
CONSTITUTION: This production apparatus consists of a lower caterpillar 2 for transferring the surface material of the building plate, a synthetic resin injection head for foamy synthetic resin and an upper caterpillar for foamy synthetic resin molding. Between guides 9 at both ends of the external circumferential surface 4 of this lower caterpillar 2 wires 5 wound closely in order to put and transfer a surface material of the building plate 2 so as to prevent caterpillar marks from being produced on the plate surface.
