Abstract:
A method of making a coated fabric to be used in a phase separation process comprising the steps of impregnating a cloth with at least one coagulable polymer latex and coagulating the polymer on/or in the cloth. The coagulation is carried from a water phase so as to provide a cloth having a porous polymer coating thereon and/or therein.
Abstract:
A filter fabric apparatus (40) for a filter press comprises two tubular members (41, 42) arranged such that one is located over the other so as to define a twin walled feed passage. A filter cloth is connected to each of the tubular members. In an alternative embodiment a third tubular member is provided between the first two members.
Abstract:
An endless belt for an extended nip press is disclosed which comprises an apertured membrane (11) having a coating layer (12, 13) of a matrix material at one or both sides thereof, the membrane including reinforcing yarns (14), extending at least in the intended running direction of the belt and the belt preferably having a ribbed or profiled surface at that side thereof remote from the shoe. Reinforcing yarns may also exist in the intended cross-machine direction of the belt and further profiled reinforcing yarns may be provided within the membrane to extend outwardly therefrom in register with longitudinally extending ribs existing at the felt side of the belt.
Abstract:
A method of forming a barrel neck connection between filter cloths (22, 23) for application to an apertured press plate is proposed, the method involving the steps of creating an aperture (13) in a flange-forming fabric having thermoplastic properties, heating the fabric in a region extending about the said aperture (13), and displacing the fabric in such region to form an outwardly extending tube (18) for telescoping engagement with a corresponding tube formed in a second flange-forming fabric arranged in opposed disposition with respect thereto. Displacement of the fabric is ordinarily effected by a plug (15) which is brought into contact with the fabric (11) and is moved into progressive engagement with a through hole (16) in a support (12) supporting the fabric (11) the plug (15) being heated and serving to heat the flange-forming material in the relevant region thereof. The flange-forming material may itself comprise a filter cloth.
Abstract:
L'invention concerne un tissu de fabrication de papier et notamment un tissu de machine à onduler, dans lequel une structure multi-couche tissée à plat est amenée sous une forme sans fin par des moyens de raccordement (14) agencés obliquement par rapport au sens de défilement du tissu et du côté du rouleau de celui-ci. La disposition angulaire de la couture a pour effet de réduire les niveaux de bruit, le marquage des feuilles et la rupture de la bande.
Abstract:
A deformable multi-layer fabric for use in forming heat resistant bodies is proposed which comprises a multi-layer fabric formed from carbon yarns, the yarns being provided in plural form in the warp and/or weft directions and preferably in plural form throughout the whole of the fabric. The warp yarns in each group Cl-C12 exist in side-by-side disposition whilst the individual weft yarns of each group W1-W6 are subjected to a small degree of twist. The fabric is capable of ready deformation without cutting and facilitates the creation of complex shapes or profiles without reference to the warp direction thereof.
Abstract:
A method of jointing the ends of a papermakers or like industrial fabric, typically a corrugator belt, is proposed wherein the ends (12, 13) of a multilayer fabric, of which adjacent layers (17, 18, 24) are joined by binder yarns, are cut back into complementary stepped configuration, the step being in a plane between two successive fabric layers (17, 18) and a clipper seam (14) is provided between the fabric layers of the respective opposing fabric ends existing below the level of the step, the fabric being slitted (at 21) beyond the line of the clipper seam and into the body of the fabric to provide a tongue (19) to receive clipper seam hooks.
