摘要:
Disclosed herein is a seaming element for attachment to an industrial textile. The industrial textile has opposed first and second seamable edge regions, while the seaming element has: i) a first lateral edge; ii) a second lateral edge; iii) a trailing edge; iv) a forward portion comprising a plurality of protruding seaming with successive loops spaced apart by an aperture, and v) a rearward portion continuous with the forward portion, with the rearward portion comprising an upper member and a lower member. The upper and lower members are substantially planar and have mutually opposed inner surfaces, with a portion of each inner surface bonded to the industrial textile at a selected one of the first and second seamable edge regions. At least one of the upper and lower member comprises one or more slits between the first lateral edge and the second lateral edge, with the one or more slits extending from the respective trailing edge in a direction towards the forward portion of the seaming element.
摘要:
A seaming element for an industrial textile and a method of manufacture. The seaming element comprises an elongate body folded along its length at a folded connection region comprising a plurality of channeled protrusions securable to corresponding channeled protrusions of a complementary seaming element affixed to an opposing seamable edge. First and second body members extend from respective edges of the folded connection region, each body member being directly securable to the first seamable edge. At least one of the body members comprises a longitudinal profiled region proximate and substantially parallel to a free edge of the respective member. The method includes providing an array of apertures to form the channeled protrusions, and the profiled region is formed in a progressive roll forming process. The seaming element enables improved consistency and reliability of bonding of the element to the textile by laser welding, adhesives or other methods.
摘要:
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.

Non-woven double layer industrial textiles comprising a plurality of interconnected selectively slit and profiled panels formed from suitable sheet or film materials. Each panel includes two fold regions at each end. Each fold region has an array of slots and strips which form hem loops and hem loop-receiving openings by folding each region beneath and toward the panel body. The panel further includes two seam regions at a central portion of the panel, which when folded, provide seam loops and seam loop receiving openings. Outside free edges of the end fold regions are returned and sealed interior to the double layer so as to avoid fraying of free ends. Each seam region of the folded panel is interconnectable with the corresponding seam region of adjacent similar folded panels by means of a seam connecting member. Additional panels composed of heat- or wear-resistant material can be connected to lateral outside edges of panels forming the textile.

摘要:
A nonwoven industrial fabric comprising a first layer secured to a second layer, with each layer comprising a plurality of flow-through apertures and profiling protrusions, wherein: a) at least a portion of the flow-through apertures of the first layer is aligned with at least a portion of the flow-through apertures of the second layer; b) the first layer comprises a plurality of securing protrusions integral to the first layer; c) the second layer comprises a plurality of detents integral to the second layer; and d) the first layer is secured to the second layer by a plurality of locking pairs, each locking pair comprising a securing protrusion lockably engaged with a detent. A method of making the nonwoven industrial fabric is also described.
摘要:
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.
