阅读说明:本技术 用于制造纤维料幅的制造装置和方法 (Production device and method for producing a fibrous web ) 是由 J.莫泽 于 2018-04-12 设计创作,主要内容包括:本发明涉及一种用于制造多层纤维料幅(2)的制造装置(1),其具有用于构成多层纤维料幅(2)的网部(3)、用于所述多层纤维料幅(2)进一步脱水的压榨部(11)和用于干燥多层纤维料幅(2)的干燥部(37),其中,所述网部(3)包括透气的第一成形带(4),所述第一成形带设置用于构成所述多层纤维料幅(2)的第一层(2a)并且将所构成的多层纤维料幅(2)输送至具有取料装置(8)的取料位置(7),其中,所述取料装置(8)包括取料抽吸元件(9)和包围所述取料抽吸元件的另外的带(10),并且多层纤维料幅(2)通过在取料位置(7)处的取料装置(8)从透气的第一成形带(4)取下,并且压榨部(11)包括至少三个压区(12,13,14),其中最后两个压区(13,14)通过第三压榨元件(17)和第二压榨元件(16)和共同的配合元件(18)构成,所述共同的配合元件(18)具有用于平整所述多层纤维料幅(2)的第一层(2a)的与透气的第一成形带(4)直接接触的侧面的光滑表面,第一压区(12)通过第二压区(13)的第二压榨元件(16)和第一压榨元件(15)构成。按照本发明规定,第一压区(12)被双层铺设毛毡并且具有顶毡(20)和底毡(21),并且所述另外的带(10)设计为透气的传送带(10)并且延伸到第一压区(12)的底毡(21)上以便构成从取料位置(7)直至纤维料幅(2)的转移位置(23)的传送区(22)。(The invention relates to a production device (1) for producing a multi-layered fibrous web (2), having a wire section (3) for forming the multi-layered fibrous web (2), a press section (11) for further dewatering the multi-layered fibrous web (2), and a drying section (37) for drying the multi-layered fibrous web (2), wherein the wire section (3) comprises an air-permeable first forming belt (4) which is provided for forming a first layer (2a) of the multi-layered fibrous web (2) and for transporting the formed multi-layered fibrous web (2) to a material removal position (7) having a material removal device (8), wherein the material removal device (8) comprises a material removal suction element (9) and a further belt (10) surrounding the material removal element, and the multi-layered fibrous web (2) is removed from the air-permeable first forming belt (4) by the material removal device (8) at the material removal position (7), and the press section (11) comprises at least three press nips (12,13,14), wherein the last two press nips (13,14) are formed by a third press element (17) and a second press element (16) and a common mating element (18), said common mating element (18) having a smooth surface for smoothing the side of the first layer (2a) of the multi-layered fibrous web (2) that is in direct contact with the air-permeable first forming belt (4), the first press nip (12) being formed by the second press element (16) of the second press nip (13) and the first press element (15). According to the invention, the first press nip (12) is double-layered and has a top felt (20) and a bottom felt (21), and the further belt (10) is designed as an air-permeable conveyor belt (10) and extends onto the bottom felt (21) of the first press nip (12) in order to form a transfer zone (22) from the removal point (7) to the transfer point (23) of the fibrous web (2).)
