Abstract: A control device (53) for a clutch assembly (11) of a dobby comprises a selecting finger (28) that is driven by an electromagnet (37). The selecting finger is rigidly connected to an armature (47) that has a curved armature section and a straight armature section. Together with an appropriately curved pole (45) of the magnetic circuit, the curved armature section forms an air gap (48) that is preferably not influenced by the pivot position of the selecting finger. The other pole (46) of the electromagnet (37) forms a preferably straight air gap (49), said air gap being variable and having a size that is a function of the pivot position of the selecting finger. Due to the existing lever ratios, the maximum width of the trapezoidal gap is substantially smaller than the path of the outer end of the selecting finger (28) between its two selection positions. The distance (A) between the pivot center (32) and the variable air gap (49) is substantially smaller than the length of the selecting finger (28).

Abstract: A new shaft drive provides for a switch-on and switch-off of individual heald shafts even at high working speeds. For this purpose switching pawls are provided which couple an eccentric with permanently revolving and/or back-and-forth oscillating disks. Measures for improving the controllability of such a clutch device are the control of the switching pawls by slot guides, associating bi-stabile biasing devices with the switching pawls and/or dividing the switching function into individual switching pawls (27a, 27b) which are associated individually with differently running disks (21, 22). Preferably, one of the two disks executes a continuous rotary motion, while the respective other disk performs only an oscillating motion which determines the heald shaft motion during the resting phases thereof.

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: 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: 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: A needle package (1), particularly for packaging needles (N), has a hold-down device (23) that is disposed in an interior space (I) and serves to secure the needles (N) in the interior space (I). The hold-down device (23) is formed, for example, by one or two resilient elements, such as clamping lips (24, 25), which extend transversely to the needles (N) through the interior space (I). The clamping lips (24, 25) are disposed on the inside of a segment of the package (1) that is moved toward the needles (N) after the package has been filled, so the clamping lips (24, 25) rest against the needles (N). The segment can be formed, for example, by a lid segment (12) that is seated to pivot on the receiving area (3) of the package (1). This package can be filled particularly simply, and is suitable for various types of needles.
