Title:
【発明の名称】大きな引張り強さを有する変形可能な繊維マットの流体動力学的な製造方法及びその製造装置
Document Type and Number:
Japanese Patent JP3178840
Kind Code:
B2
Abstract:
Disclosed is a process for dynamic-flow production of ductile, highly tear-resistant fiber mats from a fibrous web consisting of cellulose fibers impregnated with a binder and thermoplastic fibers and/or natural, vegetable fibers, where the apparatus, arranged in the flow direction of the material, consists of a web forming machine (1), a pair of press rollers (3, 4), a pair of draw-in rollers (5), a cylinder (6), an air channel (10) which is fed by ventilators (12) and fitted with one or more control members (25) in the form of one or more adjustable flaps, a venturi rod (7), a diffuser (13), a mat forming roll (15), feed rollers (16, 17), a surface weight measuring device (19), a needle machine (20), a flattening device (21), a cutting machine (22) and a stacking device (24). Disclosed also is the use of a ductile, highly tear-resistant fiber mat produced by the process as per the invention, where one or more of the fiber mats (23, 23') is used for producing form pieces by pressing at elevated pressure and temperature.
