Abstract

A device is provided for uniformly appyling foam onto textiles. The applicator includes a pair of concentric pipes dimensioned to define a space between the pipes which is filled with a porous material. The inner pipe is provided with at least one longitudinally extending slit angularly offset with respect to a longitudinally extending discharge slit in the outer pipe. Foam supplied to the inner pipe passes through its slit(s), the porous material, and the discharge slit of the outer pipe so as to be deposited on the textile material.
