发明名称 DOLL HAVING A SUBSTANTIALLY SEAMLESS FOAMED INTEGRAL TORSO AND NECK PORTION
摘要 Methods and means for producing foamed articles such as doll bodies which are substantially seamless. A limited internal discontinuity is defined during the foaming operation, and stripping of the article through a limited opening in a seamless mold part is accomplished by urging portions of the foamed article into the internal discontinuity. Pressurized gas is introduced between the article-forming surfaces of the mold cavity and the foamed article to facilitate the stripping operation.
