ABSTRACT OF THE DISCLOSURE A process and apparatus for the manufacture of high bulk paper, or a high bulk layer of a multi-layered paper, which uses a mixture of fibres in a paper- making bond forming state and substantially dry fibres. The dry fibres may be mixed with the con- ventional slurry of bond forming fibres shortly before the headbox. The web may be dried primarily by pressing, with the dry fibres remaining incom- pletely wetted throughout the process and ensuring a bulky product; through-air driers need not be used. The invention also covers the novel product of this process.
