Urethane foaming apparatus

Claim 1

AN APPARATUS USEFUL IN MAKING POLYURETHANE FOAMS WHICH COMPRISES AN ELONGATED FOAMING MOLD SUPPORT WITH A SUBSTANTIALLY HORIZONTAL BOTTOM AND WITH VERTICAL SIDEWALLS AND WHICH IS ELEVATED AT ONE END TO FORM AN APPRECIABLE DOWNWARD SLOPE, A MOVEABLE WEB LINING THE INSIDE, BOTTOM AND SIDE SURFACES OF THE SAID MOLD SUPPORT, SAID SIDE SURFACE OF SAID WEB BEING ESSENTIALLY PERPENDICULAR TO THE BOTTOM SURFACE OF SAIE WEB SO THAT A SUBSTANTIALLY USHAPED ELONGATED MOVEABLE MOLD IS FORMED, MEANS FOR DISCHARGING A FOAMABLE POLYURETHANE LIQUID STREAM ONTO THE BOTTOM SURFACE OF SAID MOVEABLE ELONGATED MOLD AT SAID ELEVATED END OF SAID MOLD SUPPORT SO THAT SAID STREAM WILL HAVE A PROPENSITY TO FLOW TOWARD THE OPPOSITE END OF THE MOLD, NARROW FLOATING ESSENTIALLY HORIZONTAL ADJUSTABLE MEANS POSITIONED FROM SAID LIQUID STREAM DISCHARGE MEANS AND ADJACENT SAID STREAM WHERE IT IS STILL SUBSTANTIALLY A LIQUID FOAM STREAM AND EXTENDING ACROSS THE SURFACE OF SAID LIUQID FOAM STREAM AND ACROSS ESSENTIALLY THE WIDTH OF SAID BOTTOM SURFACE OF SAID MOLD, A POROUS TOP COVERING MATERIAL FOR THE FOAM, SAID TOP COVERING MATERIAL BEING GUIDED INTO CONTACT WITH THE SUBSTANTIALLY LIQUID FOAM STREAM BY SAID FLOATING ADJUSTABLE MEANS AND FORMING THE TOP SURFACE OF A FOAMING TUNNEL, SAID TOP COVERING MATERIAL BEING ESSENTIALLY THE AME WIDTH AS THE BOTTOM OF SAID USHAPED MOLD AND BEING A MEDIUM THROUGH WHICH LIGHT PRESSURE MAY BE TRANSFERRED FROM SAID FLOATING ADJUSTABLE MEANS TO THE SURFACE OF THE SUBSTANTIALLY LIQUID FOAM STREAM AND ADAPTED TO APPLY EVEN PRESSURE TO SAID LIQUID FOAM STREAM AND TO ORIENT THE LIQUID FOAM STREAM TO AID IN OBTAINING UNIFORM DENSITY, SAID TOP COVERING BEING INCLINED UPWARD TO CONFORM TO THE TOP SURFACE OF THE RISING FOAM AND BEING COEXTENSIVE WITH THE TOP SURFACE OF THE RISING FOAM, A VERTICALLY AND HORIZONTALLY ADJUSTABLE CONVEYOR HAVING AN ENDLESS POROUS BELT AND BEING POSITIONED ABOVE THE TOP CONVERING MATERIAL AND PARALLEL TO THE DIRECTION OF MOVEMENT OF THE MOVEABLE U-SHAPED MOLD, SAID CONVEYOR ALSO BEING POSITIONED FROM SAID LIQUID STREAM DISCHARGING MEANS AND FROM SAID FLOATING ADJUSTABLE MEANS, THE LOWER SURFACE OF SAID BELT OF SAID CONVEYOR BEING IN CONTACT WITH THE TOP SURFACE OF SAID TOP COVERING, SAID CONVEYOR ADAPTED TO PRESS AGAINST THE TOP SURFACE OF SAID TOP COVERING MATERIAL WHERE THE FOAM REACHES AT LEAST SUBSTANTIALLY MAXIMUM HEIGHT AND THEREBY ALSO AGAINST THE FOAM TO ORIENTRATE SAID FOAM BEFORE IT IS CURRED, AND MEANS FOR MOVING SAID U-SHAPED MOLD ALONG SAID SUPPORT AWAY FROM SAID DISCHARGE MEANS, MEANS FOR MOVING SAID TOP COVERING WITH THE RISING FOAM AND WITH SAID U-SHAPED MOLD IN THE SAME DIECTION AS SAID U-SHAPED MOLD, AND MEANS FOR OPERATING SAID CONVEYOR IN THE SAME DIRECTION OF MOVEMENT AS SAID TOP CONVERING.

Claim 2

AN APPARATUS USEFUL IN MAKING POLYURETHANE FOAMS WHICH COMPRISES AN ELONGATED FOAMING MOLD SUPPORT WITH A SUBSTANTIALLY HORIZONTAL BOTTOM AND WITH VERTICAL SIDEWALLS AND WHICH IS ELEVATED AT ONE END TO FORM AN APPRECIABLE DOWNWARD SLOPE, A MOVEABLE WEB LINING THE INSIDE, BOTTOM AND SIDE SURFACES OF THE SAID MOLD SUPPORT, SAID SIDE SURFACE OF SAID WEB BEING ESSENTIALLY PERPENDICULAR TO THE BOTTOM SURFACE OF SAIE WEB SO THAT A SUBSTANTIALLY USHAPED ELONGATED MOVEABLE MOLD IS FORMED, MEANS FOR DISCHARGING A FOAMABLE POLYURETHANE LIQUID STREAM ONTO THE BOTTOM SURFACE OF SAID MOVEABLE ELONGATED MOLD AT SAID ELEVATED END OF SAID MOLD SUPPORT SO THAT SAID STREAM WILL HAVE A PROPENSITY TO FLOW TOWARD THE OPPOSITE END OF THE MOLD, NARROW FLOATING ESSENTIALLY HORIZONTAL ADJUSTABLE MEANS POSITIONED FROM SAID LIQUID STREAM DISCHARGE MEANS AND ADJACENT SAID STREAM WHERE IT IS STILL SUBSTANTIALLY A LIQUID FOAM STREAM AND EXTENDING ACROSS THE SURFACE OF SAID LIUQID FOAM STREAM AND ACROSS ESSENTIALLY THE WIDTH OF SAID BOTTOM SURFACE OF SAID MOLD, A POROUS TOP COVERING MATERIAL FOR THE FOAM, SAID TOP COVERING MATERIAL BEING GUIDED INTO CONTACT WITH THE SUBSTANTIALLY LIQUID FOAM STREAM BY SAID FLOATING ADJUSTABLE MEANS AND FORMING THE TOP SURFACE OF A FOAMING TUNNEL, SAID TOP COVERING MATERIAL BEING ESSENTIALLY THE AME WIDTH AS THE BOTTOM OF SAID USHAPED MOLD AND BEING A MEDIUM THROUGH WHICH LIGHT PRESSURE MAY BE TRANSFERRED FROM SAID FLOATING ADJUSTABLE MEANS TO THE SURFACE OF THE SUBSTANTIALLY LIQUID FOAM STREAM AND ADAPTED TO APPLY EVEN PRESSURE TO SAID LIQUID FOAM STREAM AND TO ORIENT THE LIQUID FOAM STREAM TO AID IN OBTAINING UNIFORM DENSITY, SAID TOP COVERING BEING INCLINED UPWARD TO CONFORM TO THE TOP SURFACE OF THE RISING FOAM AND BEING COEXTENSIVE WITH THE TOP SURFACE OF THE RISING FOAM, A VERTICALLY AND HORIZONTALLY ADJUSTABLE CONVEYOR HAVING AN ENDLESS POROUS BELT AND BEING POSITIONED ABOVE THE TOP CONVERING MATERIAL AND PARALLEL TO THE DIRECTION OF MOVEMENT OF THE MOVEABLE U-SHAPED MOLD, SAID CONVEYOR ALSO BEING POSITIONED FROM SAID LIQUID STREAM DISCHARGING MEANS AND FROM SAID FLOATING ADJUSTABLE MEANS, THE LOWER SURFACE OF SAID BELT OF SAID CONVEYOR BEING IN CONTACT WITH THE TOP SURFACE OF SAID TOP COVERING, SAID CONVEYOR ADAPTED TO PRESS AGAINST THE TOP SURFACE OF SAID TOP COVERING MATERIAL WHERE THE FOAM REACHES AT LEAST SUBSTANTIALLY MAXIMUM HEIGHT AND THEREBY ALSO AGAINST THE FOAM TO ORIENTRATE SAID FOAM BEFORE IT IS CURRED, AND MEANS FOR MOVING SAID U-SHAPED MOLD ALONG SAID SUPPORT AWAY FROM SAID DISCHARGE MEANS, MEANS FOR MOVING SAID TOP COVERING WITH THE RISING FOAM AND WITH SAID U-SHAPED MOLD IN THE SAME DIECTION AS SAID U-SHAPED MOLD, AND MEANS FOR OPERATING SAID CONVEYOR IN THE SAME DIRECTION OF MOVEMENT AS SAID TOP CONVERING.
