  • Publication number: 20250011987
    Abstract: An installation and method for producing a multilayer web includes a first circulating belt on which at least a first web is deposited. A cylinder mould former includes a second circulating belt and is disposed following the first device in a material transport direction for producing a layer of wet laid fibres having a top side for contacting the second circulating cylinder and being transported thereby for being deposited on the first web. An entangling and bonding device follows the cylinder mould former entangling and/or bonding the first web to the layer of wet laid fibres. A distance of 10 m maximum is maintained between the point of depositing the first web the layer of wet laid fibres. In another embodiment a second device following the first device for depositing a second web. The cylinder mould former is arranged between the first and second devices to deposit the layer of wet laid fibres on the first web before the second web is deposited.
