Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
269 words
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 stationarily arranged guiding plate for each sidewall 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 a 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.
Claim 2
Independent Claim
269 words
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 stationarily arranged guiding plate for each sidewall 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 a 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.
Claim 3
Dependent Claim
80 words
The apparatus as claimed in claim 1, additionally comprising a means for adjusting the position each of said guiding plates fixed on each side frame outside each of said guiding plates and fixed to the guiding plates, a plurality of swingingly mounted rollers fitted on both of said side frames and in the region substantially corresponding to the position of the guiding plates, and press bars for each for holding and guiding the film or sheet at its introductory part.
Claim 4
Dependent Claim
59 words
The apparatus as claimed in claim 1, wherein each of said guiding plates is formed of a front end portion of a reverse and symmetrical obliqueness to the rising angle of said foaming material, a fold portion, a middle portion of an obliqueness nearly equal to the rising angle of said foaming material, and a horizontal rear end portion.
Claim 5
Dependent Claim
28 words
The apparatus as claimed in claim 1, wherein the height of said sidewalls of said trough ranges from one-half to one-fifth the height of a finally foamed mass.
Claim 6
Dependent Claim
33 words
The apparatus as claimed in claim 1, wherein said guiding plates and said means for supplying air or gas are surface coated with a synthetic polymer pellicle having a low coefficient of friction.
Claim 7
Dependent Claim
15 words
The apparatus as claimed in claim 5, wherein said synthetic polymer is a fluorocarbon resin.
Claim 8
Dependent Claim
21 words
The apparatus as claimed in claim 1, wherein said means for supplying air is a pipe having a plurality of orifices.
Claim 9
Dependent Claim
28 words
The apparatus as claimed in claim 1, additionally comprising means for applying water droplets to said film or sheet adjacent said means for cutting said film or sheet.
