Abstract: Apparatus to make decorations on a prefabricated water-proofing bitumen-mix membrane, wherein the decorations are made by depositing solid particles, in the form of flakes, grains, sand or grit, suitable to adhere to at least one surface of said prefabricated water-proofing bitumen-mix membrane. The apparatus comprises at least one transfer member provided with a support surface suitable to receive, support and transfer the solid particles toward the surface to be enhanced of the prefabricated water-proofing bitumen-mix membrane. The support surface is provided with a plurality of cavities suitable to receive the solid particles. The cavities are made inside at least one surface portion of the support surface and the surface portion, essentially reproducing the shape and sizes of at least one of the decorations.

Abstract: The invention relates to a method and an apparatus for spinning and crimping a multifilament yarn, and wherein a thermoplastic melt is extruded through a spinneret to form a filament bundle. The filament bundle is divided into a plurality of bundle components before being crimped. Each bundle component is separately crimped and combined to a multifilament yarn after being crimped. The yarn is subsequently wound to a package.

Abstract: In a nozzle (10) for the treatment of threads, being divided in conveying direction in a conveying part (14), a compression section (16) and a guiding part (18), the compression section (16), for the purpose of forming a yarn plug, basically comprises fixedly arranged, towards each other radially and axially directed lamellar, whereat the ends of the lamellar (28) which face the guiding part, are neither in contact with each other nor with any surrounding parts of the nozzle (10), so that fibers which are being located in the gaps between the lamellar (28), and which radially exit the channel being formed by the lamellar (28), can reach an inlet funnel (18a) of the guiding part (18) or a plug guide tube (18) respectively, without colliding with any edges.

Abstract: In the production of multicolored yarn from differently colored filament bundles, the individual bundles may be texturized collectively. Then they are separated again into crimped part-threads 11.3 through 11.5 and are compacted individually in after-compacting means 8 before these part-threads are jointly compacted in a collective compacting means 9 and subsequently are wound up as a yarn 12 in a winding device 10.

Abstract: Non-woven fabric comprising polybutylene terephthalate continuous filaments having a three-dimensional crimp of unfixed shape provides remarkable resiliency, flexibility, and strength. A method of manufacturing such non-woven fabric forms a blended yarn of polybutylene terephthalate continuous filaments and highly shrinkable continuous filaments having a low melting point through direct coupling with high speed take-off means, and subjecting the resultant web to a relax heat set.
