Apparatus for extrusion of interlaced webs

Claim 2

Apparatus for making a woven web by extrusion including a plurality of spaced extrusion plates each having an opening extending therethrough, means for continuously delivering flowable strand-forming material to the openings in the said extrusion plates, and means for moving said extrusion plates in a generally horizontal plane along like sinuous paths which are 180* out of phase with each other and symmetrical, relative to a common vertical plane, with the movement of extrusion plates along one of such sinuous paths being opposite to the movement of extrusion plates along the other of such sinuous paths.

Claim 3

Apparatus as defined in claim 1 wherein the opening in the respective plates is disposed centrally therein and wherein said means for continuously delivering flowable strand-forming material to the openings in said extrusion plates includes a housing having sidewalls and a bottom wall having a slotted portion, said extrusion plates being movable relative to the housing bottom wall, and further including filler plates for maintaining said extrusion plates in spaced-apart relationship and movable therewith along said sinuous paths, said extrusion and filler plates being of like rectangular configuration and together covering the slotted portion of the housing bottom wall.

Claim 4

Apparatus as defined in claim 2 wherein said extrusion and filler plates are together moved along the sinuous paths by pushrods extending through the housing sidewalls.

Claim 5

Apparatus as defined in claim 2 wherein the slotted portion of the bottom wall of said housing includes a pair of substantially parallel, like elongated slots extending longitudinally thereof, and a series of longitudinally spaced slots extending perpendicularly between said elongated slots and together therewith defining the like sinuous paths along which said extrusion and filler plates are together moved.

Claim 6

Apparatus as defined in claim 4 including a partition positioned on the top surface of said bottom wall, a pair of like longitudinal grooves and a series of like transverse grooves formed in the bottom surface of said partition, said grooves being aligned with the slots in the housing bottom wall and together with said bottom wall defining passages along which the extrusion and filler plates travel as they are moved along the sinuous paths, and elongated and cross slots extending through said partition, said partition elongated and cross slots conforming in size and being aligned with the corresponding slots in the housing bottom wall.
