摘要:
A sheet material (1) consisting of an mixture consisting essentially of: a) 10-50 percent by weight of random-oriented fibres, and; b) 90-50 percent by weight of a thermoplastic or thermoplastic elastomer; the weight percentages being based on the overall homogeneous mixture; and the sheet material having at room temperature a Shore D hardness of 40 to 85, preferably of 40 to 60, more preferably of 45 to 55. The sheet material (1) is used as a support in punching applications or as the top layer in punching belts (2).

An apparatus for forming deformations in a nonwoven web is disclosed. The apparatus includes a pair of forming members that form a nip therebetween. The forming members include: a first forming member having a surface comprising a plurality of discrete, spaced apart male forming elements; and a second forming member having a surface comprising a plurality of recesses in the second forming member, wherein the recesses are aligned and configured to receive the male forming elements therein, wherein the recesses have a plan view periphery that is larger than, and may completely surround, the plan view periphery of the male elements. At least one of the forming members has a plurality of discrete surface texture elements thereon.

A method for manufacturing the cushioning elements (200) may include utilizing a die (310) with a plurality of die elements (312) positioned in a particular arrangement. A polymer material, which may be a polymer foam material, is located between the die (310) and an extractor (320). The polymer material is compressed between the die (310) and the extractor (320), and the die elements (312) cut the polymer material to form a plurality of pad components (230), which are arranged like the die elements (312). The die (310) and the extractor (320) are separated, and the pad components (230) are secured to the extractor (320) in the arrangement of the die elements (312). Additionally, the pad components (230) are bonded to at least one material layer (210, 220) such that the pad components remain in the arrangement of the die elements.

A laminating roller (10, 28, 100) for laminating a sheet of a packaging laminate (23, 25, 31 ) is provided, said roller comprising at least one groove (130) extending along the periphery of said roller and forming a border between two circumferential portions, wherein said each of said two circumferential portions are extending continuously around the surface area of said roller. Further, a method for providing a packaging laminate as well as such packaging laminate is presented.
摘要:
The process of the present invention employs the typical steps of manufacturing laminated plastic products, but additionally employs a programmed computer which is used to generate the identification marks and in combination with the identification marks to manage the process to define the position and attributes of each image, graphic, or text element that may appear on a face of the product. By this process, when an individual product or products are rejected as part of quality review process, they can be replaced subsequently and integrated into the production run or collated with other manufacturing steps because the program notes the products that are rejected and automatically can begin the process to manufacture another which will be individually produced.

Disclosed is a method of producing an automobile interior material or construction sheet with excellent processability, and its product made therefrom. More particularly, a method comprises by carding short fibers wherein short fibers are mixed with polypropylene fibers and polyethylene fibers in a mixing ratio of 3 to 7: 7 to 3, on one side or both sides of a foamed layer produced by foaming any one selected from the group consisting of polypropylene chips, polyethylene chips, polyurethane chips, and expanded polystyrene chips; setting the short fibers with a shape of a truss in the foamed layer by interlacing the short fibers through a needle punching process; and thermally forming the short fiber layer(s) on the foamed layer by heating the portions of the short fibers exposed on the outside the foamed layer to 120 to 250'C and pressing thereby melting, cooling and hardening the fused portions of the short fibers.
摘要:
The invention relates to multi-layer laminates consisting of at least two thermosetting binding-agent layers and two layers consisting of textiles, said laminates being suitable for reinforcing planar substrates. The inventive multi-layer system contains a binding-agent layer facing the substrate to be reinforced (11), followed by a fibrous-textile layer (13), covered by a second binding-agent layer (14), which is covered in turn by a second fibrous-textile layer (15). Once cured, the binding-agent layer facing the reinforcing substrate forms an adhesive bond with the substrate to be reinforced and has either an identical or lower elasticity modulus than the second binding-agent layer (14) facing away from the substrate. Multi-layer laminates of this type are suitable for reinforcing thin-walled substrates with no read through effect, in particular automobile construction parts with large surface areas, such as doors, roof parts, engine compartment covers, boot lids or similar.
摘要:
An open flame resistant article is composed of filling materials and a fire barrier fabric including a fire barrier layer and a thermally insulating layer at least partially enclosing the filling materials. Open flame resistance of the article is determined under the California Technical Bulletin TB 117 protocol.
