Abstract: The tool (10) for textiles according to the invention consists of chromium steel, into which carbon has been embedded in locally varying amounts during a carbonizing process. Thermal treatment achieves a formation of martensite with the maximum achievable hardness, in particular in those zones in which larger carbon fractions have been introduced. A tool for textiles with zones of differing hardnesses can thus be produced without having to subject the individual zones with differing hardnesses to different process conditions during the production process. The hardness is controlled on the basis of the degree of deformation of the tool for textiles.

Abstract: Quality assurance in sewing a textile sewn sequentially in a plurality of workstations (11) can be provided using a carriage 14 that can be moved between the workstations (11). Should a needle (12) break off in a workstation (11), the carriage (14) is moved to this workstation (11). The fragments (13) of the needle (12) are arranged in the container (20) and once it has been established that all the fragments (13) have been removed from the workstation (11) a replacement needle is provided for this workstation. The container (20) has an accommodation space (21) delimited by a main body (22) and a lid (23). A retaining magnet (34) is arranged in the region of a base (32) of the main body (22) extending along one axis (A) to retain magnetizable fragments (13) of a needle (12).

The method claimed involves the following steps: producing a prefabricated structural element (3) comprising first reinforcement structures (18), which feature textile reinforcement structures, and first thermal insulation elements (6), pouring concrete into a shell mold (13) to form a first concrete layer (11), lowering the prefabricated structural element (3) onto the first concrete layer (11).

Abstract: A textile part is configured for producing a composite-material element (11) or a composite-material body (12). The textile part (10) has a reinforcing system (15) including reinforcing warp threads (16) and reinforcing weft threads (17), and a binding system (25) with binding warp threads (27) and binding weft threads (26). The reinforcing system (15) has at least one first portion (20), into which the reinforcing threads (16, 17) are interwoven with one another directly for binding to facilitate withstanding high mechanical. The reinforcing system (15) also has at least one second portion (21), in which the reinforcing threads (16, 17) form binding-free crossover locations (22) preferably laid on one another in a drawn-out state to constitute a laid structure surrounded by the binding threads (26, 27). The laid structure of the reinforcing system (15), ensures particularly good draping and deformation capability at this location of the composite material.

Abstract: A fabric (10) for use in composite materials having a reinforcing system (11) made of reinforcing warp threads (13) and reinforcing weft threads (14), which are placed on top of one other in two different reinforcing layers (16), (17). A binding system (12) of binding warp threads (20) and binding weft threads (21) is formed from a binding yarn (30) with a lower yarn count than the reinforcing yarn (15). The reinforcing system (11) is enclosed between the binding warp threads (20) on the one side and the binding weft threads (21) on the other side, and thus, held in place at binding points (22). At each binding point (22), a binding warp thread (20) is guided and held between a stationary warp thread (25) and a regular warp thread (24) of a warp thread pair (23) of binding warp threads (20). Between two adjacent binding points of a warp thread pair (23), the stationary warp thread (25) and the regular warp thread (24) have intersecting points (26).

Abstract: A clothing wire for a clothing roller of a carding machine extends in a wire longitudinal direction and having a base segment, which is thicker transversely to the wire longitudinal direction. A leaf segment, which is narrower compared to the base segment, protrudes from the base segment. A plurality of teeth is formed on the leaf segment along the clothing wire in the wire longitudinal direction. Each tooth has two leaf segment lateral surfaces adjoining the base segment. On at least one of the leaf segment lateral surfaces, at least one projection is formed on each tooth. The cross-sectional profile of the projection is asymmetric and preferably has the contour of a nose. The design of the clothing wire results in a homogenization or parallelization of the fibers, with little wear of the clothing wire and less damage to the fibers.

The nozzle foil (12) consists of at least two adjacent foil segments (25) that can be mechanically connected with each other in a form-fitting manner. With the connection established, the upper sides (15) and the undersides (17) of the foil segments (25) are in a common plane. To accomplish a form-fitting connection, connecting means (27) provided on one foil segment (25) interact with opposing connecting means (28) of the other foil segment (25). The connecting means (27) and the opposing connecting means (28) are integral components of the respective foil segment (25) and preferably are manufactured at the same time as the respective foil segment (25) and consist of the same material as the respective foil segment (25).

Abstract: A tool unit (II) includes an ability to change the width (B) of a punching gap between a first tool (12) and a second tool (13). A plurality of second tools (13) jointly form a die tool with a circumferential die cutting edge in which the first tool (12) can engage with a cutting edge (22). Between the cutting edge (22) of the first tool and the respective cutting edge (21) of a second tool (12) a punching gap (23) is formed with a width (B) measured between the cutting edges (21, 22) across the working direction (A). Via lamping means (33), the deformation force acting on a second tool (13) can act transversely to the working direction (A), whereby the position of the affected cutting edge (21) and, with it, the width (B) of the punching gap (23), can be changed and set.

Abstract: A knitting tool (10), preferably a latch needle, intended for fast-running knitting machines has a meandering shaft with reduced-thickness regions. The meandering shaft is adjoined by a straight shaft extension (16) which likewise has a reduced-thickness portion (32). The shaft extension (16) is distinguished from the shaft (15) by way of its height H2, which is less than the height H1 of the shaft (15). The reduced-thickness region (32) of the shaft extension (16) has a length which is at least much greater than the length of the stitch-forming structure (28) carried by the shaft extension (16). Preferably, the reduced-thickness region (32) is longer overall than the non-reduced-thickness region of the shaft extension (16). With this configuration, a surprisingly efficient high-speed-compatible knitting tool (10) is created.

Abstract: A sewing needle is used in a sewing machine. The sewing needle has a working portion with a needle eye and a region which tapers into a needle tip.
