  • Linear apparatus and method for high speed production of air-laid non-woven webs
    Patent number: 3966858
    Abstract: A non-woven fibrous web is continuously air-laid by directing a fluid stream of fibers from a rotating spinner against the inner surface of a moving foraminous belt which travels in an arc substantially around the circumference of the spinner, with suction being applied to the outer surface of the foraminous belt to facilitate uniform fiber lay-down and to remove the fluid.

  • Method of preparing tobacco smoke filter
    Patent number: 3966912
    Abstract: A tobacco smoke filter element for use in cigarettes, cigarette holders, cigar holders or pipes is formed from a bonded non-woven fabric composed wholly or partly of wool fibers. It is preferred that the content of wool fibers shall be as high as is economically feasible. It is preferred that in the case of a filter for a cigarette the filter is made by converting a web of bonded non-woven fabric to a filter rod of substantially circular cross-section.

  • Method of preparing colored fibrous sheet materials
    Patent number: 3963819
    Abstract: In a method of preparing colored fibrous sheet materials wherein a fiber-pulp is treated in a defibrator to form a stream of gas containing suspended fibers which are caused to form a fibrous layer on a forming surface, a dye or dye solution is added to the fiber-pulp which is introduced into said defibrator.

  • Method of forming a lightweight airlaid web of wood fibers
    Patent number: 3949035
    Abstract: A method of forming an airlaid web at high speeds, the web being suitable for tissue and toweling applications, includes air forming a flimsy continuum on to a foraminous surface, wetting the continuum in a prescribed fashion, employing the wetted surface of the continuum to achieve stripping from the foraminous surface and transfer to a transfer surface and bonding the continuum to yield a coherent web while the wetted continuum remains adhered to the transfer surface.

  • Aligning fibres
    Patent number: 3947535
    Abstract: Aligned fibre mats are produced by passing a continuously accelerating or decelerating stream of fibre dispersion over a permeable surface and simultaneously withdrawing a limited proportion of the dispersion liquid through the permeable surface to deposit aligned fibres thereon. Mats having a wide variety of shapes and alignment patterns may readily be produced and may subsequently be impregnated with resins, metals etc. to form fibre-reinforced composite materials.
