FIELD: machine building. ^ SUBSTANCE: group of inventions refers to procedure and device for manufacture of formed item with reinforcing fibre produced by means of forming strip-like laminar material and consisting of arranged in layers large amount of sheets with reinforcing fibre and of material for maintaining laminar material to keep laminar state. Also, the formed item has at least two bent parts in its cross section shape perpendicular to lengthwise direction of strip-like laminar material and a bridge formed between ends of adjacent bent parts. The formed item has at least two flange parts projecting from the bridge through the bent parts. The procedure consists in a stage of supply of strip-like laminar material, in stage of fabrication of bent parts for making at least two bent parts, and a stage of transfer for periodic transfer of strip-like laminar material continuously located in a zone form the stage of supply to the stage of fabrication of bent parts. Also, the stage of bent parts fabrication includes at least two stages facilitated in two places in the direction of strip-like laminar material transfer. At least two stages of bent parts forming consist in the first stage of bent part forming at the nearest side downstream and the second stage of bent part forming positioned further from the first stage of forming. The first stage of bent part forming makes at least one bent part from at least two bent parts; while the second stage of bent part forming makes at least one bent part from at least two bent parts different from the bent part, formed during the first stage. At least two stages of bent parts forming can include the first stage of bent part forming positioned on one end side in the direction of width of strip-like laminar material and the second stage of bent part forming positioned on another end side in the direction of width of strip-like laminar material. The first and/or the second stage of bent part forming includes the stage of changing distance between bent parts. The device consists of a supplying unit for supply of strip-like laminar material, of a unit for fabrication of bent parts and of a carrying unit for periodic transfer of strip-like laminar material. The unit of bent parts fabrication includes at least two appliances for bent parts forming facilitated in two places in the direction of strip-like laminar material transfer. At least, two units for bent parts forming include the first unit on the nearest side downstream, and the second unit located further downstream from the first unit. The first and the second units for bent part forming have correspondingly the first and the second forms each containing two parts facing one another, opening and closing for maintaining strip-like laminar material and for exerting pressure on it to form a bent part, the first and second appliances for opening/closing to open an close the first form, and the first and second heating facilities for heating correspondingly the first and the second forms. The device can also include a mechanism for form position change for varying relative distance between the first form and the second form in the direction perpendicular to the direction of strip-like laminar material transfer. ^ EFFECT: raised efficiency of manufacture of item with reinforcing fibre; reduced expenditures and time for manufacture of said item. ^ 20 cl, 30 dwg |
