Bei einer Schervorrichtung für Stoffbahnen unter Verwendung eines einen gelochten Mantel aufweisenden hohlen Scherzylinders (12), dessen Innenraum an eine Saugeinrichtung angeschlossen ist, soll mit konstruktiv und apparativ einfachen Maßnahmen das Aufrichten der zu scherenden Fasern oder Fäden (19) im Scherbereich und der Abtransport der zu entfernenden Partikel aus der Scherzone zuverlässig sichergestellt werden. Dies wird nach der Erfindung im wesentlichen dadurch erreicht, daß die Mantelfläche des Scherzylinders vorsprungsfrei glatt ist und daß der Scherzylinder nahezu vollständig von einem bis auf eine schmale Saugöffnung im Scherbereich geschlossenen Düsenkasten umgeben ist. Dies ermöglicht eine ganz gezielte, eng auf die Scherzone begrenzte Absaugung. Deren Wirkung kann noch dadurch gesteigert werden, daß mit geringem Abstand zur Zylinderinnenwand ein Düsenrohr maschinenfest im Scherzylinder angeordnet ist. Eine apparativ besonders einfache Absaugung ergibt sich, wenn mit dem Scherzylinder mindestens ein in oder an dessen Stirnendbereich angeordneter Ventilator drehfest verbunden ist, womit besondere Unterdruckerzeuger entbehrlich werden.

A fiber mat, a component for a wind turbine, an apparatus for producing the fiber mat and a method for producing the fiber mat.

A fiber mat for use in the production of a component for a wind turbine, in particular a rotor blade, is provided. The component is curved at least in parts. The fiber mat comprises several rovings being arranged side by side and being connected to one another in at least two connection areas, wherein at least one of the rovings is continuous between the at least two connection areas and wherein at least one of the rovings is discontinuous between the at least two connection areas.

The fiber mat is advantageous in that the fiber mat can be laid along a curved path without producing wrinkles or crinkles at an inner edge of the fiber mat.

A method of manufacturing an embroidered element, the method comprising: forming a base layer comprising a polymer layer and a textile layer; embroidering the polymer layer and the textile layer with a thread such that a section of the thread lies adjacent to the textile layer and substantially parallel to the textile layer throughout a distance of at least five centimeters; and cutting the polymer layer, the textile layer, and the thread such that an end of the section of the thread is located at an edge of the textile layer. A method of manufacturing an article of footwear by incorporaing said embroided element into an upper of the footwear.

Es wird ein Scherzylinder (2) einer Schermaschine mit mehreren auf der Mantelfläche wendelförmig angeordneten Schermessern (3) beschrieben. Um den speziell beim Scheren von Flor-Noppenware gefürchteten Moirée-Effekt auszuschließen, werden die Schermesser (3) am Scherzylinderumfang mit zumindest zum Teil ungleichen gegenseitigen Abständen (a,b,c,d,e,f) verteilt.

A fabric shearing machine, having one or more shearing units, provided with a shearing drum (2) having shearing blades (4) equipped with first cutting edges (6) which respectively describe one same cylindrical path (8); a sheet (10) having a second cutting edge which makes contact with the first cutting edges (6) in operation; a table (14) having a surface for guiding the fabric (12) up to an area (16) in close proximity to the second cutting edge and lubricating means for lubricating said first cutting edges (6) and said second cutting edge, comprising a fibrous member (20) impregnable with a fatty fluid and adapted to remain in contact with said shearing blades (4). At least four fifths by volume of said fibrous member (20) are situated at a level below the level at which said area (16) in close proximity to said second cutting edge is situated.

Shearing table (10) for textile surfaces (12) which comprises a work platform (11) on which such textile surfaces (12) are positioned, the work platform (11) having advantage­ously a rectangular geometric shape, on which table (10) is comprised a headstock (17) which shears the textile surfaces (12) and can slide on a support (15) secured to the shearing table (10) in a position parallel to the longer side of the table (10), the support (15) extending along the whole length of the longer side and being positioned above the work platform (11) of the table (10) substantially in correspond­ence with the outer edge of the work platform (11), the table (10) comprising also a gripper assembly (23) cooperating with the textile surfaces (12) in a position parallel to the longer side of the shearing table (10), the gripper assembly (23) being suitable to move the textile surfaces (12) on the work platform (11) in a direction at a right angle to the direction of the sliding of the shearing headstock (17) on the support (15).

Denim fabric is treated (12-20) to raise the warp yarns adjacent the face of the fabric so that they can be rubbed and abraded to loosen the surface fibres; the tips of the warp crimp are subjected to abrading and rubbing (22) to reproduce the surface abrasion of washing and tumble drying without raising a nap or fuzzing the face. The abrading may be sanding using sandpaper in the range of about 50-100 grit, employing a 9-roll T-Ralph sander with 6 rolls running at a speed of about 50 ydm (50 metres/minute). The fabric may be lightly singed (10, 30) before raising which may be done by scouring (32) with a blend of phosphated esters; open-width washing (34) through about 5-10 wash boxes at speeds of about 30-80 yards per minute (30-75 metres/minute); first and second rope washings (36, 38) of about 15-25 minutes each, the first at about 180°F (80°C) and the second at about 140°F (64°C); drying under tension (40); finishing (42) utilizing wetters and softeners; and sanforising (44). After the abrading step (46), the fabric is shrunk (48) to 0.2% warp shrinkage.
