Abstract: A film for conveying in an industrial process, industrial fabrics made from the film, and methods of manufacture. The film has a plurality of protrusions separated by land areas. Each protrusion comprises a top member having opposing lateral edges and is supported by opposed compression resistant first and second end walls, which with at least one of the lateral edges define an aperture extending through the film to provide a flow path. The base edge of each end wall has a configuration selected from at least one of the base edge being convexly curved away from the protrusion body; and each end wall extending below at least a part of each of the first and second lateral edges and being connected to each of the first and second lateral edges. The film structure provides physical properties equivalent to a woven fabric, with improved strength, stability and compression resistance.

Abstract: A nonwoven industrial textile for conveying in an industrial process, seaming elements and methods of manufacture. The textile comprises at least first and second layers of film. Each layer comprises protrusions separated by land areas and each defining an aperture for a flow path through the layer. For at least one of the layers, the protrusions comprise a first set having first and second ends integral with contiguous land areas, and at least a second set of protrusions each comprising a first end integral with a contiguous land area and an opposing second end having a configuration selected from a detached free end; and a weakened end portion integral with but detachable from a contiguous land area in response to strain. The construction allows for relative movement of the layers during travel over machine components such as rolls, reducing internal strain and risk of delamination.

Abstract: An oriented multi-layer polymer material, an industrial textile and seaming elements therefor, and methods of manufacture. The polymer material comprises at least two thermoplastic polymeric layers, wherein at least one of the layers includes a radiation absorbent material to provide a weldable outer surface of the polymer material and at least one of the layers permits through transmission of laser energy. The polymer material can be provided as a bi-axially oriented film or as a filament; and allows for accuracy and reliability of welding, while avoiding the disadvantages associated with accurate placement and alignment of separate welding strips.

Abstract: A seaming element for an industrial textile, a textile with seaming elements, and a method. The seaming element has first and second end regions, a fold line in an intermediate fold region, and outer and inner surfaces. Each end region comprises slits extending from the outer surface through to the inner surface, defining protrusions which provide a profile to at least one of the surfaces. Apertures aligned along the fold line define a plurality of land areas. When the seaming element is folded along the fold line, the land areas form a plurality of loops defining a channel. When the seaming element is secured at each end region to a first end of the industrial textile, the loops are interdigitatable with corresponding loops on a compatible seaming element at a second end of the industrial textile, to define a single aligned channel to receive a securing means.

Abstract: A seaming element for seaming an industrial textile, an industrial textile, and a method of seaming. A first region of the seaming element comprises at least one securing member, and a second region is securable to the textile. Spaced-apart protrusions in the securing members are interdigitatable with corresponding protrusions in an opposing element, or the other seamable edge of the textile. Opposing protrusions are interdigitated to define first and second channels for securing means. Where the seaming element has two or more securing members, the protrusions of the outer securing member are aligned with those of an inner securing member of the opposing element, and the protrusions of an inner securing member are aligned with those of the outer securing member of the opposing element. Where the securing means is a pintle, the free ends can be inserted back into the channel to secure the seam.
