Abstract: A heddle shaft is formed of a hollow metal profile section into which an expanding element for vibration damping is inserted. The expanding element is for example a precompressed foam strip which expands after insertion into the internal chamber of the hollow metal profile section until it is seated with a certain initial tension between the side walls of the hollow metal profile section. It is embodied as a solid (non-liquid) body and is introduced as such into the internal chamber. For being locked in place, it can be provided with adhesive faces.

Abstract: In a heddle (6), the slender heddle shank (21) has been lengthened, at the cost of the end eyelets (7, 8) and the yarn eyelet region (29). This is accomplished on the one hand by shortening the end eyelet regions (7, 8) to their absolute minimum length and on the other by placing the auxiliary openings (38), which serve to transport the heddles, closer to the end eyelets (7, 8). The radii R in the region of the end eyelets (7, 8) are reduced. Instead of the usual 2 mm width, the heddle shank (21) still has a maximum width of 1.6 mm. The regions (14, 13) of the heddle (6) that protrude past the end openings still have, instead of the usual length of 4 mm, a length of 2.5 mm to 3 mm. Directly around the yarn eyelet (33), the heddle has a width which, as before, is equivalent to twice the width of the yarn eyelet (33). However, the length of this region is shortened to a maximum of twice to three times the yarn eyelet width.

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 stamping device (1), which in particular is arranged for stamping unfired ceramic substrates, has a die holder device (8) with a plurality of dies (4, 5, 6, 7), which for activation can be locked to the die holder device (8) and then jointly with it execute an axial stamping motion. A coupling device (18) which is remote-actuated is used for the locking. For the remote transmission of the actuation motion, a flexible mechanical connecting means is used, such as preferably a cable (16).

Abstract: The heddle shaft rod (4) described originates in an extruded aluminum profile section with relatively thick side walls, which are removed in some regions and thereby made thinner. This can be done without substantial impairment to the rigidity of the heddle shaft rod, yet as a result a substantial reduction in weight is attained. The removal of material can be adapted to the local load conditions. For instance, it is possible at the ends or other force introduction points to leave unweakened thick walls, while the other regions of the side walls are milled off far enough that a uniform thinner wall thickness is attained. It is furthermore possible to vary the amount of material removed, either in multiple steps or in infinitely graduated fashion. The material removal pertains to a reduction in the wall thickness that is measured transversely to the movement direction of the heddle shaft rod.

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 needle (1) for loop-forming machines has a needle body (2) with two even flat sides (6, 7), which are joined to one another on the top and back sides of the needle by narrow sides (5, 8). A narrow slit opens out at one of the narrow sides and extends parallel or at an acute angle to the flat sides (6, 7) into the needle body. A substantially rectangular fastening portion (21) of the transfer spring (14) is retained in this slit (16) by positive and/or nonpositive and/or material engagement.

Abstract: A latch needle (1) has a latch spring (19), which assumes the width of the latch slit (5) in the vicinity of the latch seating (18). However, the latch spring (19) is embodied to be narrower on both sides of this section (25). By means of this, premature wear of the latch or spring in the area of the latch seating device (18) is counteracted on the one hand as is, on the other, the obstruction of the latch slit (5) by dust or dirt. The narrower sections (26, 27) of the latch spring (19) define a passage together with the inner face (8, 9) of the slit walls (6, 7), through which foreign bodies, such as fiber remnants, dust or the like can be conveyed from the upper needle side (11) in the direction toward the needle back (12). In contrast to conventional latch needles, needles (1) of this type of construction show reduced wear, a reduced susceptibility to becoming soiled, and therefore increased dependability.

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: A punching tool for green sheets or similar sheetlike workpieces has a support plate, with punched holes (7) embodied in it, and a holding-down plate, which is disposed above the support plate and in which holding-down openings (24) are embodied. Dies (8) extend with their operative portions (23) through the stripper openings (24) and are guided in them. The operative portions (23) are embodied in graduated form. They have a punching portion (26) of reduced diameter. The length of each punching portion (26) is less than the length of the stripper opening (24). When the die (8) is at its top dead center, the punching portion (26) is located entirely in the stripper opening (24). Moreover, a fragment of the portion (25) that belongs to the operative portion (23) protrudes into the stripper opening (24), in order to guide the die (8).

Abstract: A needle pouch made of a flexible material, such as paper or plastic, for an orderly packaging of needle sets (6), formed of a strip-shaped portion from the desired material. One end of the strip is folded onto the shanks of the needles and is, at the edges, connected to a mid portion on which the needle set is positioned. The connection is effected between the folded-over pouch portion (15) and the mid portion (14) which are in a face-to-face relationship. The strip-shaped locations of connection bilaterally confine the needle set and thus tightly hold the needles against one another. The needle pouch (2) may be made automatically and in a simple manner and may be adapted in the simplest way to different needle sets.

Abstract: An improved punching tool (1) has a lower tool (3), which is subdivided into a lower tool base plate (7) and a lower-tool operative part (8). The lower tool base plate (7) has a receiving face, with which uniform base areas of a plurality of lower-tool operative parts (8) are associated. The dividing place between the lower-tool operative part (8) and the lower tool base plate (9) is disposed such that all the workpiece-specific designs are present exclusively on the lower-tool operative part (8), while the lower tool base plate (7) is the same, without change, for all workpieces to be machined.

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: For keeping knitting tools (2) in readiness and mounting them on knitting machines or other loop-forming machines, a tool holder (4) is provided, which is formed by or contains a transport rail (5). The transport rail (5) has two clamping legs (9, 11), which are parallel to one another and are provided with regularly distributed slots (16, 17). The slots firmly clamp inserted knitting tools by frictional engagement. With the knitting tools (2), the transport rail (5) forms a manipulable unit, in which when it is freely handled, the knitting tools (2) do not fall out of the transport rail (5). The pitch of the transport rail preferably matches the pitch of a needle bed of a machine to be equipped. The equipping of the machine is done by placing the transport rail on the needle bed or attaching it to it and pressing the knitting tools away, in a direction approximately perpendicular to the back portion (6) of the transport rail (5), out of their frictionally engaged mounting into their needle channel.

Abstract: To improve the handling of a needle (1) having a selector element (16) that is seated to pivot on the needle body (2), a fastening element (32) is additionally provided. This element secures the selector element (16) to the needle body (2) in a form fit. One or more individual securing elements (34, 35, 36) acting in the transverse direction (33) serves or serve as the fastening element (32). The individual securing elements (34, 35, 36) can act in one direction or in both transverse directions. They are embodied to prevent the selector element (16) from falling out of the needle body (2) in both lateral directions. For this purpose, at least one individual securing element 34, 35, 36 that acts in the transverse directions 33a, 33b is provided. It is possible to combine all of the individual securing elements 34, 35, 36.

Abstract: A latch needle (1) has a latch spring (19), which assumes the width of the latch slit (5) in the vicinity of the latch seating (18). However, the latch spring (19) is embodied to be narrower on both sides of this section (25). By means of this, premature wear of the latch or spring in the area of the latch seating device (18) is counteracted on the one hand as is, on the other, the obstruction of the latch slit (5) by dust or dirt. The narrower sections (26, 27) of the latch spring (19) define a passage together with the inner face (8, 9) of the slit walls (6, 7), through which foreign bodies, such as fiber remnants, dust or the like can be conveyed from the upper needle side (11) in the direction toward the needle back (12). In contrast to conventional latch needles, needles (1) of this type of construction show reduced wear, a reduced susceptibility to becoming soiled, and therefore increased dependability.

A narrow slit opens out at one of the narrow sides and extends parallel or at an acute angle to the flat sides (6, 7) into the needle body. A substantially rectangular fastening portion (21) of the transfer spring (14) is retained in this slit (16), by positive and/or nonpositive and/or material engagement.

Abstract: The needles (18, 19) of a needle set (17), which substantially agree in their geometry, have butts (28, 29) of different lengths, which have a predetermined breaking point (57, 58). The predetermined breaking points are differently embodied, so that the breaking torques of the butts (28, 29) of the needles (18, 19), which are a part of the set (17), are different. By means of this it is possible, on the one hand, to assuredly prevent damage to the knitting machine, but on the other hand to assure the dependable operation of the needles.

Abstract: A package (1) for packaging and storing elongated items such as sewing needles (2, 3) has a tray (5) and a lid part (6), which are held or connected together to define a housing space. The tray (5) and the lid part (6) each have a flap-type section (14, 19) at their bead end. These sections can be pivoted toward and away from one another, and can be latched together. When the two flaps (14, 19) are pivoted away from one another, they expose the ends of stored items, e.g., the sewing needles (2, 3), projecting out of the housing space (48), so the items can easily be pulled out of the housing space (48). It is therefore possible to secure the items or sewing needles (2, 3), for example, in a frictional, in the housing space (48).

Abstract: A stamping device includes a base body; an elongated punch having a longitudinal axis; a supporting arrangement for holding the punch in the base body and for guiding the punch for axial displacements between an advanced position and a retracted position; a driving unit releasably held in the base body and including a driving device for axially displacing the punch; a coupling device having a first state in which the coupling device operatively connects the driving device with the punch and a second state in which the driving device is disconnected from the punch; and a receiving arrangement for holding the punch in a desired axial position when the coupling device is in its second state.
