Abstract
"SISTEMA DE FORMAçãO DE FOLHA". A invenção se refere a um sistema de formação de folha (1) de uma máquina de fabricar uma folha de massa fibrosa (2), de uma suspensão de massa fibrosa (3, 3.1, 3.2), com um formador de tela longa (4.1), que apresenta uma cinta de desaguamento (5), e com uma caixa de entrada (6, 6.1) que abrange uma instalação de adução (7, 7.1, 7.2) de uma suspensão de massa fibrosa (3, 3.1, 3.2) que apresenta um bloco de turbulência (8, 8.1) com vários canais (9.i) para a geração de correntes individuais turbulentas (10.i), e um bico de caixa de entrada (11), cujo jato de suspensão de massa fibrosa (12) incide numa superfície livre (13) da cinta de desaguamento (5) do formador de tela longa (4.1). A invenção se caracteriza pelo fato de que o bloco de turbulência (8, 8.1) substituível, consiste de um bloco de material sintético inteiriço (14), no qual foram abertos vários canais (9.i), e que o bico de caixa de entrada (11) apresenta um comprimento de bico (L~ D~) de <242> 400 mm."SHEET FORMATION SYSTEM". The invention relates to a sheet forming system (1) of a fibrous dough sheet forming machine (2), a fibrous dough suspension (3, 3.1, 3.2) with a long web former (4.1). ) having a dewatering belt (5) and an inlet box (6, 6.1) covering an adduction installation (7, 7.1, 7.2) of a fibrous mass suspension (3, 3.1, 3.2) features a multi-channel turbulence block (8, 8.1) for generating turbulent individual currents (10.i), and an inlet nozzle (11) whose fibrous mass suspension jet ( 12) focuses on a free surface (13) of the dewatering belt (5) of the long screen former (4.1). The invention is characterized by the fact that the replaceable turbulence block (8, 8.1) consists of a block of one-piece synthetic material (14), in which several channels (9.i) have been opened, and that the gearbox nozzle The inlet (11) has a nozzle length (L ~ D ~) of <400 mm.
