ABSTRACT:
A method and apparatus for the application of foam backing to a fabric web without the introduction of hose and streak marks on the fabric breaking. A foam pillow is established on a fabric web by confining it on two sides thereof with guide plates, and on the front thereof with a doctor blade or stationary roller. The web is started moving, whereby the pillow is caused to generally roll or rotate about a generally horizontal axis. A gap of predetermined size between the bottom of the doctor blade or roller and the top surface of the web allows only a portion of the foam from the pillow to adhere to the web and be carried along therewith, the foam providing a backing for the fabric. The volume of foam in the pillow is maintained by the introduction of new foam into the volume of the pillow at at least two points on either side of the pillow, to flow generally along the axis of rotation of the pillow.
