A deposition nozzle has a housing, an inlet into the housing arranged to receive a solution carrying randomly oriented fibers, an orientation component within the housing, the orientation component positioned to receive the solution from the inlet and operate to produce aligned fibers in a predetermined, single direction, and an outlet on the housing arranged to receive the aligned fibers and deposit them on a substrate. A system includes a porous substrate, a deposition nozzle, a reservoir of randomly oriented fibers in solution connected to the deposition nozzle, the deposition nozzle position adjacent the porous substrate and connected to the reservoir, the nozzle to receive the randomly oriented fibers and output aligned fibers, and a vacuum connected to the porous substrate to remove fluid from the porous substrate as the deposition nozzle deposits the aligned fibers on the porous substrate to produce a fiber pre-form having aligned fibers. A method includes providing a reservoir of randomly oriented fibers in a solution, dispensing the solution of randomly oriented fibers through a nozzle having an orientation component onto a porous substrate as a solution of aligned fibers, and immobilizing the fibers to form a fiber pre-form.

| PURPOSE: To fully spread chitin without shrinkage by a method wherein chitin as stock is gradually pressed vertically through an upper and a lower reservoirs by an upper and a lower endless belts so as to separate and remove water content from the stock and, at the same time, spread the stock so as to form chitin sheet. CONSTITUTION: An upper and a lower belts 14 and 15 are narrowed toward their leading sides. In addition, chitin as stock liquid 18 under the state being pinched by an upper and a lower reservoirs 16 and 17 is passed between the belts so as to smoothly separate the water content retained therein from the chitin as stock liquid through the pores of the porous reservoirs for dehydration. The water content passes under vacuum through a net or the pores 15a of the porous lower belt 15 and falls on a dehydrating plate 7 provided beneath the net or the lower belt and is discharged. Further, since the chitin as stock liquid 8, some degree of dehydration from which is performed by a press roller 10 and rollers 9g and 9f, is pressed as is integrally pinched by the upper and the lower reservoirs 16 and 17 and consequently the shrinkage of the chitin is checked by the upper and the lower reservoirs, the chitin is fully spread, even though the chitin has originally plenty of shrink characteristics.

| PURPOSE: To manufacture a reinforced polymer product by bringing reinforcing fiber as well as an aqueous suspension of alternate copolymers of a carbon monoxide and an olefinic unsaturated compound into contact with an outside surface of a rotary wheel having a plurality of molds, and dewatering by pressure reducing and drying operations. CONSTITUTION: A reinforcing fiber of 60 to 80 wt.% and having a length of 3 mm or more and an aqueous suspension of 20 to 40 wt.% of alternate copolymers of a carbon monoxide and an olefinic unsaturated compound having an intrinsic viscosity measured in an m-cresol if 60°C of 0.5 to 10 dl.g -1 are brought into contact with an outside surface of a rotary wheel having a plurality of molds protruding inside or outside for dewatering the suspension by pressure reducing the inside. A substance adhered into or on the mold of the wheel is dewatered by a pressure reducing and at least partly drying operations including heating of the adhered substance. The molded product is removed from the wheel, and a reinforced polymer product is manufactured. The molded product can be executed for an operation for effectively improving a stability of profile dimensions by drying by again hot air drying or microwave or high frequency heating.
