ABSTRACT:
A process is disclosed for the joining of lines of acetalyzed polyvinyl alcohol foam with each other or with textile fabrics. The process is characterized by the fact that the parts of the lines to be joined together are brought into contact with each other and hot pressed, in the presence of moisture at tool temperatures of from 100.degree. to 300.degree. C. and a pressure of 1-10 kp/cm.sup.2. The process is further characterized by the fact that the line of acetalyzed polyvinyl alcohol foam is saturated with water to its swelling limit, and by the application of the process to a line of formaldehyde-acetalyzed polyvinyl alcohol foam, of which the degree of acetalyzation amounts to about 20% by weight.
