Abstract: A joint bearing 8 is provided between two structural elements of which one is connected with the connecting joint 17 and the other with a hinge pin. In the connecting joint 17, there is provided a pressed-in outer ring 28, a cage 30 located between the hinge pin and the outer ring. The cage 30 is provided with cylindrical roller bodies 31, as well as stops 34, for the axial guiding of the cage. The outer ring 28 is so thin-walled that after pressing into place its inner circumference, must be reworked. The outer ring 28 only extends over the length of the roller body 31. The stops 34 are separated from the outer ring 28 and are attached to the connecting joint 17. Further, the hinge pin 20 may be constructed as a tube 19. The appropriate structural element (lever 9) contacts the outside of tube 19. By means of an outwardly protruding screw or other fastener 21 from the inner space of the tube, this structural element is attached onto the tube wall.

Abstract: A warp knitting machine with bearded needles (5) and a pattern press comprises a driven press bar (10) having individual press elements thereon. These are so controllable that during the working stroke (47) of the press bar (10) at choice there is provided a press contact onto the hooks (19) of the corresponding bearded needles (5) or not. Every pressing element (46) is provided with a piezoelectric bending transducer ((42) attached at one end whose free end (45) in the direction of the needle bed may either move from a first position during the working stroke 47 into a press contact and in a second position in which the press element 46 or a power transmitting element located forwardly thereof in the direction of the needle bed may be displaced. In this manner, it is possible to provide a safely constructed pattern press suited for high velocity operation.

Abstract: In a device for fastening active components (18) to the bar (6) of a warp knitting machine, the bar (6) has transverse channels (24) each of which is intended to receive a guide section (25) of the active component (18), and a longitudinal groove (20) for receiving holding sections (21) of the active component (18). The longitudinal groove (20) has an uncovered insertion opening area. The transverse channels (24) are arranged next to it. The holding sections (21) are wedged into the longitudinal groove (20) by means of the force of a spring (22). A tool (29) for removing and installing the active components (18) has a first driver (34) carried by an operating handle (31), which driver is fitted to a first stopper (35) on the active component (18) and contributes towards extracting the holding part (21) from the longitudinal groove (20). The result of this is a structure without play, with precise positioning and minimal weight.

Abstract: A segment carrying knitting elements for a warp knitting machine comprising a plurality of similar plates. Holes provided in said plates are penetrated by at least one hollow pin, which at its circumference is connected with the plates. This gives rise to low weight segments for attachment to the bars of a warp knitting machine.

Abstract: A warp knitting machine comprises a jacquard guide bar (102) whose guides (7) are movable to and fro between two end stops (113 and 114). This motion is effected by setting members of a guide control. The end positions of the guides have a separation equal to two needle spaces. Additional strikers (115) and (116) are, at choice, made operative by the setting members (transducer 108) of a stop control. When one of the additional strikers is in an operative position, that striker holds the guide (7) in a central position. In particular, needle control and stop controls may operate with piezoelectric transducers. In this manner, it is possible to obtain an extremely large number of patterning possibilities.

Abstract: A stroke control arrangement (1) for influencing individual threads of a thread sheet, in particular for a warp knitting machine, comprises entrainment devices (20) controllable by piezoelectric transducers (19). The entrainment devices (20) are provided adjacent to the transducers (19) in the transverse direction and are born at one end thereof in a portion (25) supported by a carrier (16) and carry at the other end thereof a transport stop (37). The transport stop (37) in a first position carries a stroke element, which in a second position of the transport stop (37), to the contrary, is left uninfluenced. In this way there is obtained a reliable system for stroke control.

Abstract: An electromagnetically-operating Jacquard control device has an electromagnet (1) with a magnetic core (3), an armature (8) and a limit stop (14) for each controlling element (16) to be controlled. The limit stop can optionally be brought into the movement path of a hook (18) attached to the controlling element (16). Two lovers (5, 11) are provided, the first bearing the armature (8) and the second bearing the limit stop (14). These two levers are coupled to one another with positive engagement such that the forces are transmitted substantially perpendicularly to the plane formed by the limit stop (14) and the swivel pin (12) of the second lever (11). This enables wear-related incorrect operation to be avoided.

The arrangement includes a thread brake 5 having a local portion 6 and a portion 8 movable relative thereto, between which the thread 1 is pulled during the wind-up or wind-off and which provides a frictional force upon thread 1. Furthermore, the arrangement includes an actuator 13 for applying a frictional force applied by thread brake 1 to thread 1 may be controlled. Preferably included is a piezoelectric sensor 14 which may be deformed by the force applied by the thread to the sensor 14. In the prior art, the actuator comprises a setting nut and a spring whose operation is time-consuming.

Abstract: A flexible electric cable (1) has a conductor (2,3) and a fiber layer (4,5) of electrically conductive fibers which are in contact therewith. A cable of this type (1) is particularly suitable for electrical connection between two components that can move In relation to each other, one of which carries numerous activating elements, which may be controlled by voltage pulses. In this way, cables which are under stress through vibration, bending and tension stress, etc., can retain their function over a longer period.

Abstract: Textile machine in particular a warp knitting machine having attached, side-by-side, on a carrier (1), stroke elements (2) which grip on the threads, which are individually displayable in the longitudinal direction. To the carrier (1), are provided control element (21) which are electrically activatable and can be brought into two positions. A common activating arrangement (8) which runs along the length of the carrier (1) and is driveable to and fro in the stroke direction, influences the stroke element (2) in the first position of the appropriate control element (21) in the at-rest position and carries it with it in its second position in a working mode. In this manner it is possible to control the individual stroke elements without the need for harness cords.

Abstract: A holding device can holding implements for a knitting machines such as needles or guides. A needle (or guide) head (2) is held detachably on a carrier (9) by means of plug-type connections and a locking device. The needle head (2) is connected in one piece with a shank (3), which is flat and has a lateral recess (16) near its end. A holder (4) is arranged on the carrier (9). Following a guide section (19) matched to the shank cross section, the holder has a sprung catch (15) movable in the shank plane perpendicular to the shank axis. This catch can engage the recess (16) under pretension. More particularly, the holder (4) has between two external cover plates(6, 7), a middle plate (5) having free punchings forming the guide section (19) and the spring tongue (14). In this way the needle heads can be easily replaced individually.

Abstract: In a method for manufacturing a warp knitted fabric, the guides can also be displaced by one needle space (pitch) in addition to the overlap and underlap shog of the guide bar, so that the guides are not only selectively displaceable during the underlap shog, but also selectively during the overlap shog. A warp knitting machine for the purpose of carrying out the method comprises at least one thread system which consists of pattern threads laid in intermixed, varying patterns. These pattern threads have underlaps of n, n+1 and n-1 needle spaces and can produce a float and/or a twill. The number of pattern possibilities can be increased in this manner.

Abstract: A Jacquard bar (1) for warp knitting machines having at least one row of guides (4), which can be moved to and fro between two stops (6). A thread redirecting edging (11) covers the intermediate spaces between the stops (6). The redirecting edging (11) is fixed positionally by connection with the stops (6). In this way the weight of the components bearing the redirecting edging can be reduced allowing precise positioning of the guides in operation.

Abstract: In a warp knitting machine at least one guide bar (8,9) carries piezoelectric bending transducers (14,15) to which are attached guides (11,12). A control arrangement (16) comprises a computer (17,19,20) and a potential generator, which provide the control potential via control lines (25) to the bending transducers. The potential source provided to a guide bar (8,9) comprises a plurality of serial to parallel converters (23) whose data and command inputs (22) are connected via a common data and command bus (21) with the computer and whose outputs (26) are connected with the bending transducers via the control lines (25). The serial to parallel converters (23) take up the data sequentially and upon occurrence of the switching command transmit them simultaneously in the form of control potentials. In this way rapidly running and/or large warp knitting machines can be provided with a operative piezoelectric jacquard control.

Abstract: A guide bar arrangement for a warp knitting machine has at least one guide bar, which is axially displaceable by means of a displacing arrangement and is carried, suitably on an axially rigid holding arrangement attached to a swinging shaft, through the intermediation of a compensating arrangement. The compensating arrangement and the displacement arrangement include bending transducers, which are attached at one end thereof on the holding arrangement (a lever 19 holding rails) and on the other end thereof on the guide bar and are bendably deformed under the influence of a direct current control signal. This leads to a simple construction of the guide bar arrangement with little frictional loss.
