Abstract:
1. A double-conveyor type apparatus for manufacturing a floor mat formed of foam resin having excellent elasticity and standardized to a given size such that a flat underside surface of the floor mat comes into close contact with each floor surface of a variety of buildings and a top surface of the floor mat having a plurality of protrusions formed thereon is adapted to prevent sliding thereon, the double-conveyor type apparatus comprising: a plurality of unit upper molds each having a flat surface adapted to be in series connected to each other to form an upper conveyor, so as to mold the flat underside surface of the floor mat; a plurality of unit lower molds each having a plurality of concave grooves formed thereon adapted to be in series connected to each other to form a lower conveyor, so as to mold the top surface of the floor mat having the plurality of protrusions formed thereon; and an uncoiler disposed at the front of each of the upper and lower conveyors so as to continuously supply a mat attachment film to the surface of each of the upper and lower conveyors, wherein the foam resin is supplied to a front end portion of the lower conveyor and conveyed to a space between the surfaces of the upper and lower conveyors by means of the mat attachment film being supplied from the uncoiler, and while conveyed, the foam resin is foamed and molded to continuously produce the floor mat, wherein each unit lower mold of the lower conveyor is of two styles of unit lower molds, that is, a first style unit lower mold having the plurality of concave grooves formed on the surface thereof, and a second style unit lower mold having an end portion-forming horizontal bar protruded in a width direction along the center of the surface on which the plurality of concave grooves are formed, so as to mold shapes of front and back end portions of the floor mat, such that when the number of the first style unit lower molds arranged between the second style of unit lower molds is adjusted, the length in the forward and backward directions of the floor mat is adjusted.
