Abstract
Improvements in the object of the patent 376,332, for Improvements in the devices for forming fibrous sheets, and more particularly in the devices for forming a fibrous sheet (W) from a dilute aqueous suspension of imbricated fibers that move together and leave from a slit (11a) in the manner of a jet stream, substantially unidirectional and tape-thin, devices comprising first (13) and second (14) head cylinders mounted to rotate in a horizontal plane and spaced at a distance that defines a space (G) that extends generally vertical, opposite first (F1) and second (F2) sections of fabric that move substantially at the speed of the jet stream, by the first (13) and second (14) head cylinders), respectively, by an initially small spacing in the space (G), which receive the jet stream between them and which move immediately afterwards converging by a forming zone and towards a general parallelism with the wet fibrous sheet (W) trapped between them, in which parallelism the fabric sections (F1, F2) are maintained as they move together, characterized by the sections (F1, F2) of fabric with the sheet (W) imprisoned between them are moved upwards by a plurality of substantially aligned and staggered opposing sheet means (15a, 15b), successively spaced away from the space (G) in the direction of the current in jet, defining between them a generally vertical wavy displacement path aligned upwards that generally coincides with the direction of the jet stream, each of the laminar means (15a, 15b) having a smooth and fixed surface that presents a curved edge (15y) of entrance to one of the sections of fabric, edge that forces the one of the sections of fabric towards said parallelism against an opposite zone of the other of the sections of fabric free of contact with restrictive means and that guides the one of the fabric sections in parallelism by a turn away from the direction of the jet stream with a relatively fast rate of deviation to extract water through and from the other of the fabric sections.
