ABSTRACT OF THE DISCLOSURE Improvements of an apparatus for continuously producing a sheet shaped product from polymerizable liquid raw material are disclosed by using confronting upper and lower endless belts. In one of the improvements, a feeding means for feed- ing the liquid raw material into the apparatus comprises at least a liquid raw material feeding device detachably mounted on a carrier engaged with a part of the apparatus. The car- rier has means for mounting the feeding device thereon whereby the feeding device is always prevented from coming into con- tact with the upper and lower endless belts. In the other improvement, the apparatus is provided with means for contin- uously feeding gaskets from the stock into the apparatus in order to seal the side openings of the space between the end- less belts, at a speed substantially the same as the running speed of the endless belts. The gasket feeding means com- prises a heater through which the sealing gaskets pass prior to being fed into the apparatus while undergoing heating whereby residual stress present in the sealing gaskets is re- moved, and deformation of the sealing gaskets is eliminated. - 1 -
