发明名称 Method for continuously producing a synthetic polymer foamed mass having square cross section
摘要 An apparatus for continuously producing a synthetic polymer foamed mass having square cross sections which comprises a travelling conveyor belt, a channel-shaped continuously extending trough mounted on said belt and moving with the travelling of said belt for filling with a foaming liquid material, the two sidewalls of said trough being lower than the height of a finally foamed mass, adjacent to each of said sidewalls, inside said trough and in the region where foaming of said foaming liquid material begins to occur and is finished a stationarily arranged guiding plate nearly flush with or higher than the height of a finally foamed mass, said guiding plate having in the middle portion thereof an oblique upper rim portion of an obliqueness nearly equal to or slightly greater than the rising angle of the foaming material and being formed in a twisted and folded shape, a bag-shaped or elongated tubular film or sheet of an synthetic polymer or resin surrounding each of said guiding plates, said film or sheet being movable along said guiding plate in the same direction as and at an equal speed to the speed and direction of said trough and upwardly along the lateral ends of said foaming material in the area of said oblique upper rim portion of said guiding plate, means fixed to the front end of each of said guiding plates for blowing air or a gas into said film or sheet, and means for cutting the top portion of each of said films or sheets, said means being fixed on the rear end portion of said oblique upper rim portion, is disclosed.
