Method of manufacturing a foamedrubber article

Claim 1

A METHOD OF MANUFACTURING AN ARTICLE CONSISTING AT LEAST IN PART OF FOAMED RUBBER, COMPRISING THE STEPS OF PREPARING A LIQUID RUBBER LATEX MIXTURE FOAM BATH, PREPARING A CARRIER HAVING GAS ESCAPE PASSAGES FORMED THEREIN, HEATING THE SAID CARRIER TO A TEMPERATURE EXCEEDING THE GELLING TEMPERATURE OF THE SAID LATEX MIXTURE FOAM, IMMERGING THE HEATED CARRIER INTO THE SAID LIQUID FOAM BATH UNTIL THERE IS FORMED A GELLED LAYER OF THE RUBBER LATEX MIXTURE ON THE SURFACE OF THE CARRIER WHILE A COATING OF THE LIQUID FOAM OF HTE MIXTURE ADHERES TO THE SURFACE OF HTE GELLED LAYER AND WHILE GAS LIBERATED FROM THE GELLED LAYER, WHILE GELLING, AND FROM THE LIQUID FOAM LAYER IS VENTED THROUGH SAID GAS ESCAPE PASSAGES, THE GELLED LAYER BEING SITUATED BETWEEN THE CARRIER AND THE LIQUID FOAM COATING, WITHDRAWING THE CARRIER WITH THE GELLED LAYER AND ADHERING LIQUID FOAM COATING FROM THE FOAM BATH, IMMEDIATELY EXPOSING SAID CARRIER TO A GELATION PROMOTING ATMOSPHERE SO THAT GELLATION OF THE LIQUID FOAM COATING OCCURS PROGRESSIVELY FROM THE OUTER SURFACE OF THE LIQUID FOAM COATING TOWARD THE GELLED LAYER, HEATING THE WHOLE TO THE VLCANIZING TEMPERATURE OF SAID RUBBER LATEX MIXTURE UNTIL THE SAID LAYER HAS BEEN VULCANIZED, AND REMOVING AT LEAST PART OF THE SAID CARRIER FROM THE ARTICLE THUS OBTAINED.

Claim 2

A METHOD OF MANUFACTURING AN ARTICLE CONSISTING AT LEAST IN PART OF FOAMED RUBBER, COMPRISING THE STEPS OF PREPARING A LIQUID RUBBER LATEX MIXTURE FOAM BATH, PREPARING A CARRIER HAVING GAS ESCAPE PASSAGES FORMED THEREIN, HEATING THE SAID CARRIER TO A TEMPERATURE EXCEEDING THE GELLING TEMPERATURE OF THE SAID LATEX MIXTURE FOAM, IMMERGING THE HEATED CARRIER INTO THE SAID LIQUID FOAM BATH UNTIL THERE IS FORMED A GELLED LAYER OF THE RUBBER LATEX MIXTURE ON THE SURFACE OF THE CARRIER WHILE A COATING OF THE LIQUID FOAM OF HTE MIXTURE ADHERES TO THE SURFACE OF HTE GELLED LAYER AND WHILE GAS LIBERATED FROM THE GELLED LAYER, WHILE GELLING, AND FROM THE LIQUID FOAM LAYER IS VENTED THROUGH SAID GAS ESCAPE PASSAGES, THE GELLED LAYER BEING SITUATED BETWEEN THE CARRIER AND THE LIQUID FOAM COATING, WITHDRAWING THE CARRIER WITH THE GELLED LAYER AND ADHERING LIQUID FOAM COATING FROM THE FOAM BATH, IMMEDIATELY EXPOSING SAID CARRIER TO A GELATION PROMOTING ATMOSPHERE SO THAT GELLATION OF THE LIQUID FOAM COATING OCCURS PROGRESSIVELY FROM THE OUTER SURFACE OF THE LIQUID FOAM COATING TOWARD THE GELLED LAYER, HEATING THE WHOLE TO THE VLCANIZING TEMPERATURE OF SAID RUBBER LATEX MIXTURE UNTIL THE SAID LAYER HAS BEEN VULCANIZED, AND REMOVING AT LEAST PART OF THE SAID CARRIER FROM THE ARTICLE THUS OBTAINED.
