Abstract

The apparatus is for the dry formation of fibrous tissue and incorporates a mixer (6) which has a channel, in which are inclined, downwardly directed guide plates for formation of a labyrinth channel. With the guide plates are placed spiked rollers which create a fiber-loaded air current. The mixer issues via a funnel-shaped outlet aperture (7) into a distributor (10). - The distributor has a rotor with fingers. The rotor impels the fibers through an outlet (18), which either directly or via a tube (15) feeds to an outlet aperture (13), which is connected to inlet apertures (14) in shaping receptacles (6).

Description

PATENTKRAV 1. Apparat til tørformning af et fibrøst væv, omfattende organer til opblanding af op-splittede fibre i en luftstrøm og til fremføring af den fibermedbringende luftstrøm til en formerkasse, der er anbragt oven over en formerwire overfor en vakuumkasse, hvilket fibermateriale valgt blandt syntetiske fibre og naturlige fibre, kendetegnet ved, at opblandingsorganeme omfatter en kanal, der ved modstående vægge har guideplader, som er rettet ind i kanalen for dannelse at en labyrintkanal, at der ved guideplademe er anbragt roterende pigvalser, som skaber en fibersky i luftstrømmen gennem kanalen, at det omfatter en distributor, der har en rotor med et antal vinger, og som er anbragt mellem opblandingsorganeme og formerkassen, og som har et eller flere udløb, der udmunder i formerkassen. 2. Apparat ifølge krav 1,kendetegnet ved, at rotoren har et antal stort set radialt orienterede vinger, hvilken rotor er anbragt i et kammer har et centralt indløb for luf-topblandede fibre og at udløbet/udløbene er stort set cirkulære idet tilslutning til formerkassen er dannet tilspidsende i ét plan og udvidende i et plan vinkelret herpå for at danne et eller flere spalteformet indløb i formerkassen. 3. Apparat ifølge krav 1 eller 2, kendetegnet ved, at opblandingsorganemes kanal, har et udløb med en tragtformet tilspidsning. 4. Apparat ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at guideplademe er orienteret skråt nedefter og dækker mellem 15 og 50%, fortrinsvis ca. 30 % af kanalens tværsnit. 5. Apparat ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at opblandingsorganeme omfatter guideplader der er anbragt overfor hinanden på modstående sidevægge, og at der under hver af guideplademe er tilvejebragt en pigvalse med pigge der tilnærmelsesvis dækker tværsnitsarealet under den spalte, der er dannet mellem to guidepladers frie sidekanter. 6. Apparat ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at der er anbragt mellem to og fire niveauer af guideplader i en kanal. 7. Apparat ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at hældningen på guideplademe er mellem 15 og 60°.A device for dry forming a fibrous web, comprising means for mixing split fibers into an air stream and for conveying the fiber carrying air stream to a mold box disposed above a mold wire opposite a vacuum box, said fiber material selected from synthetic fibers and natural fibers, characterized in that the mixing means comprise a channel having, at opposite walls, guide plates which are directed into the channel for forming a maze channel, that rotating spike rollers are arranged at the guide plates, which create a fiber cloud in the air flow through the channel It comprises a distributor having a rotor having a plurality of blades arranged between the mixing means and the molding box and having one or more outlets opening into the molding box. Apparatus according to claim 1, characterized in that the rotor has a plurality of substantially radially oriented blades, which rotor is placed in a chamber having a central inlet for air-top blended fibers and that the outlet (s) are substantially circular when connected to the forming box. is formed tapering in one plane and expanding in a plane perpendicular thereto to form one or more slit-shaped inlets in the mold box. Apparatus according to claim 1 or 2, characterized in that the channel of the mixing means has an outlet with a funnel-shaped taper. Apparatus according to any one of the preceding claims, characterized in that the guide plates are oriented obliquely downwards and cover between 15 and 50%, preferably approx. 30% of the channel cross-section. Apparatus according to any one of the preceding claims, characterized in that the mixing means comprise guide plates arranged opposite one another on opposite side walls and that under each of the guide plates there is provided a spike roller with spikes approximately covering the cross-sectional area below the gap. formed between the free side edges of two guide plates. Apparatus according to any one of the preceding claims, characterized in that between two and four levels of guide plates are arranged in a channel. Apparatus according to any one of the preceding claims, characterized in that the inclination of the guide plates is between 15 and 60 °.
