Abstract
Improvements in the object of the patent 376,340, for: Improvements in the arrangements for forming fibrous sheets, and more particularly in the apparatus for forming a relatively light fibrous sheet, starting from a dilute aqueous suspension of manufactured fibers that move together and that Appliances comprising first (13) and second (14) head cylinders mounted to rotate in one direction are exited in the downstream direction from a slit in the manner of a high speed, substantially unidirectional jet stream. common vertical plane and spaced at a distance such as to define between them a narrow space (G) substantially horizontally aligned, first (F1) and second (F2) sections of forming fabric that move substantially at the speed of the jet stream on the first (13) and second (14) head cylinders respectively by a small initial spacing in space (G) to receive e Between both the jet stream and immediately thereafter converging through a formation zone in general parallelism with the wet fibrous sheet (W) trapped between them, in which parallelism the fabric sections (F1, F2) are maintained when moving downstream jointly, characterized in that the sections (F1, F2) of forming fabric with the sheet (W) imprisoned between them move on the third (15), fourth (16) and fifth (17) guide-fabrics, having the third guide- fabrics (15) a smooth, generally curved, fixed and waterproof surface that presses one of the fabric sections (F2) towards said parallelism against an opposite area of the other section (F1) free of contact with restrictive means to gradually increase the pressure against the other fabric section (F1), in order to effectively force water through the other fabric section (F1), while simultaneously rotating the one (F2) of the fabric sections in such parallelism through a path d e generally curved displacement substantially coinciding with the third fabric guide surface (15); the fourth fabric guide (16) presenting a rotating surface to receive the fabrics (F1, F2) in parallel from the third fabric guide (15) and to direct the fabrics (F1, F2) gradually separating them from the direction of the current jet to effectively force water through the other length (F1) of fabric; the fifth fabric guide (17) presenting a fixed water removal surface, downstream of the fourth fabric guide (16) in working relationship with the sections (F1, F2) of forming fabric against the one (F2) of the fabric runs, which surface directs the fabric runs (F1, F2) in a substantially straight line of travel from the fourth fabric guide (16) to effectively remove water from the one (F2) of the fabric runs.
