Apparatus for applying foam onto continuously advancing webs of material in which several nozzles are provided which are connected to a foam distributor which comprises a chamber with foam outlets as well as a distribution rotor which rotates in the chamber and is in communication with a foam feed line directing the foam from the inside toward the foam outlets.

Apparatus for applying foam

In apparatus for applying foam to a moving web comprising a foam generator and a foam box which is coupled to the foam generator, the foam box arranged transversely to the web, extending over its width, and having on its underside an opening which extends over the width of the web and under which a rotatable cylinder is arranged which extends over the width of the web, the cylinder being sealed against the foam box except for an exit for the foam, the cylinder in its rotation, carrying foam from the foam box along at its surface and depositing it on the web passing underneath the cylinder, is a wall element is disposed on the side of the cylinder which is descending during revolution, the wall element, together with the cylinder, forming a canal which is tapered in the circumferential direction of the cylinder with the canal ending in the region between the height of the axis of the cylinder and one half the height of the cylinder above, and a wiper inclined downwardly toward the web rests against the cylinder below the end of said canal to permit foam to be deposited on the web by gravity.

Apparatus for applying foam to a moving web

A nozzle which produces a wide liquid jet includes a housing open on one side with two longitudinal edges, one of which forms one edge of the nozzle aperture with the other edge of the nozzle aperture formed by the free end of a wall connected to the other longitudinal edge of the housing. Bolts are distributed over the width of the nozzle aperture outside the nozzle aperture for adjusting the wall over the nozzle width to slightly deform the wall and change the thickness of the nozzle aperture.
