Abstract: A knitting tool (1) is provided with a braking spring (15) formed on the knitting tool as a one-piece member thereof. The braking spring has a thickness (W) which is less than that of the knitting tool (1), whereby the braking spring (15) may yield to a great extent and has a soft spring characteristic. Such a result may be achieved even with short spring lengths, whereby dimensional deviations of the spring have only a slight effect on the spring force. The structure is only slightly prone to soiling. The knitting tool may be manufactured in a simple manner.

Abstract: The latch needle (1) of the invention has a latch (7), which is provided on its free end, on its side facing away from the hook (3), with one or more recesses (18, 19). The function of these recesses is to reduce the moment of inertia of the latch (7), which leads to an increased service life of the latch. Between the recesses (18, 19), a rib remains, whose top side functions like a skid for loops to be transferred. The indentations (18, 19) are preferably elongated depressions. However, corresponding openings may be provided as a substitute instead.

Abstract: A shed forming device (1) for a power loom has a plurality of heddle shafts, to which a drive mechanism with a plurality of servo motor groups (13, 14) is assigned. The servo motor groups are located below each of the heddle shafts (3 through 8), in each case as a cluster, and they are located with their pivot axes (27 through 32) on a circle, an ellipse, or a similar figure. They are also axially offset from one another. Each servo motor (15 through 20) is provided with a driven lever (21 through 26). The free ends of all the levers are located approximately at the center of the circle or ellipse or other figure of revolution. They are connected to the heddle shafts (3 through 8) via connecting rods (34 through 39) and form various angles with the connecting rods (34 through 39). The result is a drive mechanism with little inertia, low resilience, and little play. Very fast shaft motions can be attained in a controlled way.

Abstract: A latch needle (1) is provided with a latch (5), which has a clearing profile (19) on its latch shank end (18). The clearing profile (19) serves to keep the sawslot (6) free of dirt. To that end, it has at least one special clearing face (24).

Abstract: A plurality of machine elements, such as needles (2), are combined into a shipping unit (1) by material connections, such as an adhesive bond, and this shipping unit can be easily transported and stored. The machine elements can easily be separated by hand or with simple tools and inserted individually, for instance into the needle tracks of a knitting machine.

Abstract: A shaft rod (2), wherein the heddle support rail (4) is secured in a form-fit to a profile body (9), for example in the form of an aluminum extruded profile, by projections (18) provided on the extrusion profile (9), with the projections 18 extending into substantially correspondingly shaped recesses (19) in the heddle support rail.

Abstract: A device for machine knitting with at least one continuous yarn, in which the yarn, by a hook part of a knitting needle, is passed in a loop through a previously formed loop and forms a new loop, in which the knitting needle, below a needle hook, has a slot into which a downward-oriented transfer hook movable in a vertical direction can be introduced, and the transfer hook is introducable into the slot by a simultaneously controllable transverse motion.

Abstract: A knitting machine needle (1), having a butt (3) pointing away from its needle body (2) and a shank (15) extending from the needle body as far as a hook (16), has a deflection (18) which is disposed between the hook (16) and the butt (3). The deflection (18) is provided with at least one recess (24), which locally alters the wave resistance of the deflection (18) and leads to a reduction in hook breakage when the butt (3) is exposed to impacts.

Abstract: A heddle (14) of the invention is distinguished by end eyelets (15, 16) of reduced size, with which heddle support rails (6, 7) of reduced cross section are associated. The axial play of the heddles on the heddle support rails (6, 7) is limited to from 0.5 mm to 1.5 mm. The lateral play is in the range of 0.2 mm to 0.5 mm. This system formed of heddle support rails and heddles is especially suitable for particularly rigid heddle shafts for power looms with an extremely high operating speed.

Abstract: A novel corner connector for heddle shafts has detent means with which it can be retained in a shaft rod. The load-related locking is effected independently of the detent means by a clamping device that acts between the struts of the shaft rod.

Abstract: A heddle shaft (1) has shaft rods (2, 3), which are embodied as profile bodies (12) having at least one hollow chamber (14). The shaft rods (2, 3) are joined together by lateral bracing posts (4, 5) and at least one center connector (11). For securing the latter, retaining pieces (23) are disposed in the hollow chambers and are accessible through windows (22). The retaining pieces (23) are preferably glued into the hollow chamber (14) and have one or more threaded bores for securing the center connector (11) by means of screws (37).

Abstract: A heald shaft for weaving machine has a shaft rod (3) which is formed of a one-piece light-metal profile and two stiffening bodies (24, 25) glued to the shaft rod (3). The stiffening bodies bridge the entire width of the shaft rod (3), wherein the width is measured between the side walls (11, 12). The chambers 14, 16 for receiving the stiffening bodies (24, 25) each have at least one open side through which the stiffening body is visible from the outside and through which it may be introduced into the respective chamber (14, 16). This construction facilitates manufacture. Further, a rigidity in the working direction, as well as a good rigidity transversely thereto is achieved.

Abstract: A shaft rod for a heddle shaft is formed by a profile body (15) and an associated additional profile body, which are joined together by a detent means (25) and additionally by an adhesive bond. The detent means (25) is embodied such that it already holds the additional profile body (19) fixed and in the correct position on the profile body (15) when the adhesive that forms the adhesive seam (33) is still liquid or viscous, or in any case has not yet thoroughly hardened. This provision makes it substantially easier to manipulate the shaft rod (4) during manufacture.

Abstract: A novel shaft gear for harmonious engagement and disengagement of individual heddle shafts and for deriving their motion from the rotary motion of a single input shaft has a coupling system with two input elements. While one of the input elements serves to drive the output element of the coupling system permanently, the other input element serves solely to synchronize the output element briefly with the first input element. The switchover takes place in the brief synchronous phases, in selected angular regions that correspond to the top or bottom reversal point of the heddle shaft. For the switchover, such novel shaft drive mechanisms do not require any stoppage of motion for the input shaft or the shaft drive mechanism.

Abstract: A latch needle (1) is provided with a latch (5), which has a clearing profile (19) on its latch shank end (18). The clearing profile (19) serves to keep the sawslot (6) free of dirt. To that end, it has at least one special clearing face (24).

Abstract: A novel rod linkage for driving a heddle shaft includes at least one strap (16), which for damping oscillation has a sandwich structure (37) oriented in the longitudinal direction (L) of the strap assembly (16). The sandwich structure includes at least one rigid element (27), extending in the longitudinal direction, which is joined to one end (17) of the strap assembly (16); a second rigid element (31), likewise extending essentially in the longitudinal direction, which is joined to the other end (19); and a two-dimensional damping element (34), again extending in the longitudinal direction, disposed between the first two. The element (34) exclusively effects the mechanical connection of the two parts (16a, 16b) of the strap assembly (16). Preferably, no additional connecting elements, such as rivets, screws, or other rigid connections, between the rigid elements (27, 31) are provided.

Abstract: A knitting tool (1), particular for high-speed knitting machines, has a shank (2) that is provided with indentations (33, 34). For embodying these indentations, the shank (2) is provided with a slit (25), which creates two legs (29, 31) spaced apart from one another. These legs are bent toward one another so that the desired indentations are created at the flanks (27, 28). The indentations serve to reduce friction and to hold oil.

Abstract: An improved knitting tool, comprising a loop-drawing needle (2) and a transfer needle (3), is improved in terms of its operational reliability, its versatility of use, and its knitting speed, by providing that the loop-drawing needle (2) has a cheek region (12) which is widened compared to the rest of the shank (5) and which is provided with a noucat (16). On the end of the cheek region (12) remote from the hook (9) of the loop-drawing needle (2), a control face (36) is provided, along which the transfer needle (3) runs with its control face (37), as a result of which the spacing between the loop-drawing needle (2) and the transfer needle (3) changes. The transfer hook (26) of the transfer needle (3) is wider than the hook (9) of the loop-drawing needle, and the hook tip is sharpened or pointed in order to fit into the noucat (16) in the loop-drawing needle, Because the transfer hook (26) is embodied as especially wide, the operating safety is increased substantially.

Abstract: A selection element (16) is movably seated in a system element, for example a needle (1). As an assembly aid for temporary fixation, a material-to-material connection in the form of an adhesive, lacquer, a laser weld spot or a thin strip of material is provided on at least one connecting point (34), which breaks or is dissolved in the course of first use.

Abstract: A stitch needle (10) is provided with a tip (29) which is shaped as a center punch and has no recognizable rounding at its terminus (31). The tip (29) is preferably arranged at mid height of the hook-shaped aperture (36) which is structured for capturing the yarn (13). The particular shape of the tip (29) and its positioning minimize the wear of the stitch needle (10) and also minimize damages to the yarn (13).
