Abstract: A needle-holding device (1) suitable in particular as a package comprises a flat needle carrier section (4) and an adjoining section that has a clamping lip (5) that is resiliently biased against the needle carrier section (4). The clamping lip (5) reaches around the stitch-forming sections of the needles (2) which are held lying next to each in contact with each other on the needle carrier section (4). The resiliently yielding clamping lip (5) permits the insertion and the pull-out of one, several or of all the needles (2).

Abstract: The new gripper design provides a gripper (3) for tufting machines, said gripper comprising a slider (18) that is supported so as to be movable in longitudinal direction. This slider is arranged in a slider receiving space (17) which, preferably, is configured as a slit. The slit extends from the lower narrow side (12) of the gripper body (4) into said gripper body. Said slit is limited by two thin walls (19, 20) or, alternatively, by only one thin wall (20). A cutting edge insert receiving space 39 is provided above the slider receiving space (17), said receiving space (39) extending from the flat side (9) and being recessed in the gripper body (4). Between the cutting edge insert receiving space (39) and the slider receiving space (17), a strip (40) is provided that preferably extends in longitudinal direction of the gripper body (4) and separates the receiving spaces (39, 17) from each other. This design is suitable for the creation of very narrow grippers (3) that permit a division of less than 1/10 Inch.

Abstract: A shaft transmission 3 for a weaving machine comprises a shaft arrangement (8) that supports, on one end, a crown wheel (10) in order to drive the shaft arrangement (8). The shaft arrangement (8) is supported by means of two bearing arrangements (12, 13), between which a package (28) comprising the cam disks (29 through 29i) is non-torsionally held on the shaft arrangement (8). The part (18) of the shaft arrangement (8), which supports the package 28, is connected with the remaining part (17) of the shaft arrangement (8) via a clutch arrangement (19) that represents a separating point. The clutch arrangement (19) is configured, e.g., as a frictional clutch with a cone (39) and an appropriate cutout (40), and is secured, in connected state, by means of a locking means (41) that is to be actuated from one end of the shaft arrangement (8).

Abstract: An inventive heddle for jacquard machines essentially consists of fiber-reinforced plastic material, whereby the thread eye is formed by a mail (12). The heddle body comprises two legs (3, 4). Between the relatively wide thread eye region (5) and the legs (3, 4), ramp sections (6, ) are provided, which sections have a length that is greater than the length of the thread eye (1). Preferably, the length is greater than twice the longitudinal extension of the thread eye. In most cases, said length is between 10 and 30 mm. As a result of this measure, the wear of the plastic material in the vicinity of the thread eye (13) is kept minimal enough that neither any damage to the stiffening fibers (22) in the body of plastic material nor any damage to the warp threads needs to be feared.

Abstract: A nozzle bar used for the water-jet compacting of a fibrous web has an opening on the side facing the fibrous web into which a nozzle strip (5) can be inserted. This nozzle strip is provided with at least one row of nozzle openings (6) for generating parallel water jets that are focused onto the fibrous web and function to compact the fibrous web. The nozzle strip (5) is formed with martensitic hardened steel.

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 inventive coupling rod (12, 42) for a shaft drive rod assembly (11) of a heald shaft (1) is designed as an open bent sheet metal component. The cross-section of this component is uniform along the length of the coupling rod (12, 42), with the exception of its ends (13, 14). Such a coupling rod (12, 42) permits the construction of shaft drive rod assemblies which are cost-effective and light-weight, and are suitable for the high operating speeds of the weaving machine.

Abstract: A system component (1) for a knitting system is composed of a body (3) with butt (18), which projects outward from the narrow side (16) of the body (3). According to a first advantageous embodiment of the invention, the butt (18) is positioned inclined or at an angle to the body (3). A corresponding bending line extends in longitudinal or movement direction of the body (3). The angle (?) is thus defined in an imaginary plane (E) that intersects the body (3) in transverse direction. As a result of this measure, the butt (18) can also be adjusted relatively precisely at a right angle to the cam movement if the system component (1) along with it the body (3) is arranged somewhat inclined inside a corresponding guide slot (4) of a bed (5), wherein the angle ? then compensates for the tilting. A line-type contact between the butt (18) and the guide track (7) is achieved, which reduces wear.

Abstract: Referring to a rehanging needle, the shaft is provided with a cutout that receives the tip of a rehanging spring. The cutout is divided into a first section and a second section, whereby the two sections have different depths. When a half stitch slides onto the rehanging spring, the spring tip can use the space due to the recessed second section and sink into said space, without the rehanging spring experiencing a permanent deformation. Consequently, it is possible for the half stitches to consistently and reliably slide up in order to set up the rehanging operation.

Abstract: The component placement set in accordance with the invention for equipping a knitting machine consists of the system components that are required for equipping the knitting machine, said system components being sorted according to type and arranged in one package in different chambers. The chambers are closed all around and protect the packaged system components against environmental influences and against loss. Preferably, the package can be opened only by destroying it, in which case the chambers of the package can be cut open independently of each other. The order of the system components in the individual chambers preferably corresponds to the order in which they are to be placed in the knitting machine. This applies, in particular, to system components having different foot positions.

Abstract: The knitting method in accordance with the invention is based on simple knitting tools without means for closing a thread-receiving space that is created by a simple cutout configured as a stitch support shoulder. In the simplest case, the stitch is formed by a simple back-and-forth movement of two knitting tools relative to each other, whereby said knitting tools can be arranged approximately at a right angle with respect to each and can be alternately pierced through each other. In so doing, the taken up thread is pushed through the half stitch respectively carried by the other knitting tool. The knitting method is based on simple and sturdy tools that are minimally susceptible to wear. Considering the manufacture of left-left knitted goods, this method permits, in addition, a significant increase in productivity compared with conventional machines while, at the same time, featuring greater simplicity of the knitting process and of the knitting tools.

Abstract: A novel tufting needle (4) is distinguished by a hollow flute (15) which is preferably symmetrical to a central plane (29) and which is bilaterally provided with chamfers (33, 34). The chamfers (33, 34) are, in an inward-located, that is, in a region lying close to the central plane (29), inclined at a small acute angle (?) to a reference plane (28), while in a region bordering an externally located rim (edges (46, 47)), the chamfers (33, 34) are inclined at a larger acute angle (?) to the reference plane (28). This feature improves the rigidity, the tufting properties and the mechanical strength, as well as the wear resistance of the novel tufting needle (4).

Abstract: A heald (heddle) shaft (1) comprises at least one shaft rod (2) on which a damping element (12)is supported on the shaft rod carrier body (15) to be movable in the longitudinal direction of a heald or heddle (8) mounted on a shaft stave or rail (6) carried by the body (15) so as to be moveable toward and away from an abutment surface (26) of the support body (15) and an outer end surface (22) an eyelet of a heald or heddle (8) mounted on the shaft stave (6). By virtue of movably supporting the damping element (12), an alignment of the healds or heddles (8) is improved and facilitated, and a desired damping effect is obtained during the entire motion course of the healds or heddles (8).

Abstract: A latch needle (1) having a latch (6) provided on its latch spoon on the side facing away from the hook (4), with at least two facets or molded surfaces (10, 11). These facets (11, 11?), which converge toward the latch back (23), decrease the volume of the latch head (8). Consequently, it is possible to reduce the width C of the recess (27), thus resulting in a stabilization of the knitting machine needle (1) in this region.

Abstract: The machine knitting needle of the invention, beginning at its hook (3), between the hook (3) and its latch bearing (9), has a convex or at least not concave shank contour, which defines the inner hook contour and on one end (18) adjoins the concave inner hook contour directly. It is attained as a result that the elevation angle which a yarn (23), located in the hook (3), must overcome if it is to slide on the shank does not increase at any point along the inner contour (17). Preferably, it even decreases steadily. It thus has its maximum value inside a space which is defined on the one hand by the inner hook contour (15) and on the other by a plumb line (L) or (L1) which is dropped, from the hook tip (12) or its tapering portion (11), onto the needle back (16), or if the needle back is not oriented parallel to the direction of motion of the machine knitting needle, onto the arrow that defines the direction of motion.

Abstract: An apparatus according to the invention for producing a knitted fabric with interspacing is embodied in the form of a circular knitting machine with knitting cylinders or with a knitting cylinder and a dial. Between the two needle beds for the needle assemblies defined in this way, a pile thread transfer device 4 is arranged, which is preferably provided with two groups 5, 6 of feed elements that can respectively be moved from an idle position to a thread tucking position. In the process, the feed elements of the one group move toward the needle hooks of the first needle bed and the feed elements of the other group move toward the needle hooks of the other needle bed. In this way, a spaced apart knitted fabric can be produced on circular knitting machines, wherein latch needles can be used and the needle stroke is limited to the standard measure of less than 14 mm. The knitted fabric with interspacing can have a thickness of clearly more than 14 mm, meaning a thickness than far exceeds the needle stroke.

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: An improved heald consists of a flat material, such as tempered steel. It has closed (O-shaped) end eyelets (5, 6) which are one-piece parts of the heald body (4). An edge (10) which extends along the full length of the heald (1), is of entirely straight configuration. In contrast, the oppositely-located edge (11) consists of offset straight portions. A particularity of the heald according to the invention resides in the fact that the openings (15, 16) provided in the end eyelets (5, 6) for receiving the shaft staves are eccentrically arranged, whereby the two webs (17, 18) bordering the openings (15, 16) have unlike widths. With a reduced material input and weight a heald is obtained which, as concerns stability and possibility of utilization in existing weaving systems is at least equivalent to conventional healds.

Abstract: An improved heddle (2), on its end eyelet (7), has a spring means (14) which braces the end eyelet (7) resiliently in at least one direction on a heddle support rail 3. The spring means (14) serves to avoid play between the heddle (2) and the heddle shaft (1). This provision makes it possible to increase the operating speed of power looms.

Abstract: A device for the manufacture of perforated films or foils comprises a means (5) for the perforation of the film or foil (2), as well as a means (19) for crimping the edges of the thusly produced holes. By crimping the edges, the holes are fixed after having been opened. Punching tools for cutting the perforation out of the film or foil are not required. Rather, the desired hole is first created as a puncture, or as a cut, and is then widened. During the crimping operation, the material bent out of the plane of the film or foil is fixed in place in such a manner that it will not close the pierced hole again.
