FIELD: textile, paper. ^ SUBSTANCE: invention relates to manufacture of products from fibrous material, namely egg cartons, glasses for drinks, food trays. There used is the first device which is permeable to air and water and the second device which is heated up to temperature at least 220C. Raw material is supplied to a forming bath. The first device is submerged into it and the initial product is shaped on it by means of application of negative pressure through it. After the first device is taken from initial raw material, it is supplied to the second device. Formed product from fibrous material is placed between the first and the second device. It is heated with the second device with evaporation of at least some water contained in the shaped product from fibrous material. Water is removed until dry matter content in it is at least 70%; after that the product is subject to drying with superhigh frequency radiation. ^ EFFECT: providing uniformity of strength properties of the product, effective dehydration and preventing its surface being burnt through. ^ 29 cl, 33 dwg |
