摘要： In the method according to the invention, a wire (11) provided with teeth (15) passes sequentially through a first inductor (16) and a second inductor (18). The inductors (16, 18) function at different frequencies and generate different temperatures. The first inductor (16) heats in particular the base section (17), which is not to be hardened, to a high temperature below the austenitizing temperature range. The second inductor (18) heats the teeth (15) to a still higher second temperature within the austenitizing temperature range. Defined, hardened teeth of consistently high quality result at quenching.

摘要： A method and a device for the automated transport of weaving accessories is disclosed. A device is provided which has at least one rail and at least one rail carrier. The at least one rail carrier carries the weight of the at least one rail, on which weaving accessories can be movably disposed in the longitudinal direction of the rail. The method is characterized in that the at least one rail carrier is displaced relative to the at least one rail, in the longitudinal direction thereof, in order to move weaving accessories disposed at the rail along the rail in the longitudinal direction thereof.

摘要： A device (1), a sinker arrangement (5) and a method for loop-forming are described. The device (1) may include a cylinder (2) with first grooves (3) for needles (4) accommodated in a first groove (3), whereby the needles (4) include a loop forming section, and a sinker ring (27) with second grooves (15) for the sinker arrangement (5). The sinker arrangement (5) may include an actuating section (12) and a loop forming section (7). The loop forming section (7) includes an opening (11), and the sinker arrangements (5) are accommodated in one single second groove (15). The opening (11) may be delimited in the width direction (x) by two side faces (23) and the loop forming section of the needle (4) is movably disposed between the two side faces (23) of the opening (11).

摘要： The invention relates to a textile machine tool part (11) that is used in textile processing in a textile machine and to a method for producing same. The textile machine tool part (11) has a tool core (16) made of a core material and is coated, at least in part, with a wear-resistant coating. The wear-resistant coating (17) is applied to a core surface (18) that has a first microstructure (19). The first microstructure (19) is preferably created using electrochemical etching in the core surface (18). The wear-resistant coating (17) applied thereto is preferably applied directly to at least a section of the core surface (18) having the first microstructure (19) using electrochemical deposition and has a layer thickness of a maximum of 20 μm.

摘要： A loop-forming process includes moving a plurality of system components (11, 12) relatively to a needle bed (14). The system components (11, 12) contact threads (23) for forming loops. At least one spacer (10) is placed between at least two adjacent system components (11, 12) of the plurality of system components (11, 12) and defines the distance (21) between the two adjacent system components (11, 12), the spacer (10) being in mechanical contact to the two adjacent system components (11,12). The spacer (10) is placed away from and does not contact threads (23) and is moved with respect to the needle bed (14). The spacer (10) is also moved with respect to both of the two adjacent system components (11, 12) at least for a period of time during the loop forming process. An equivalent device is also disclosed and claimed.

摘要： A reed and a method for producing a reed. The reed has a multiplicity of dents, which are arranged in a width direction, forming interspaces each having a dent spacing. Each dent has two opposite end sections, at which the dents are respectively connected to a carrier and to the immediately adjacent dent or dents by an adhesive connection. In at least one end section, the dent has a plurality of a spacer studs, which are preferably produced by embossing. The spacer studs form a depression on the one, first side and, on the opposite, second side, form a projection having a stud outer surface. The sum of all the stud outer surfaces of the spacer studs of a single end section of a dent has a proportion of at most 15% of the total end section surface on this second side.

摘要： A sewing machine needle includes a blade extending substantially in the needle's longitudinal direction, an eye, which passes through the needle substantially in its elevational direction, and a scarf, which extends along the needle behind the eye. Compared with the contour of the blade, the scarf contour is recessed in the needle's elevational direction. At least in part of the scarf's extension along the needle, the scarf contour in a sectional plane perpendicular to the needle's longitudinal direction is substantially an arc of a circle. The circular-arc-shaped area covers a first angular portion of the needle's circumference. In this part of the scarf's extension along the needle, the radius of the substantially circular-arc-shaped contour in this first angular portion of the needle's circumference is between 35% and 100% of the needle's maximum lateral reach. The needle's lateral direction is perpendicular to its longitudinal and elevational directions.

摘要： A loop gripper (10) for a tufting machine has a gripper body (11) with a gripper finger (12) extending in an extension direction E from a retained end (13) to a free end (14). On the gripper finger (12) underside (16), a cutting region (20) transitions into a sliding surface (19) at a transition point (21). A retaining element (35) near the transition point (21) is mounted to be pivotable about a pivot axis S relative to the gripper finger (12). The pivot axis S extends in a transverse direction Q at right angles to the extension direction E. The retaining element (35) is urged into a starting position A by a force, for example a spring force and/or a weight force. In the starting position A, a retaining surface (37) of the retaining element (35) extends obliquely or at right angles away from the sliding surface (19).
