Abstract: A tufting needle is disclosed. The needle consists of a butt (3) and a shank (7). The butt can be integrally formed at least partially in a needle module (1), while the shank has a needle tip, provided with an eye (9), and a thread guide groove (8) on one side as well as a chamfer (10) at one edge of the side (11) which is located opposite the thread guide groove (8). A chamfer (10) is likewise provided at a second edge of the side (11) opposite the guide groove (8), and the tufting needle is symmetric relative to a plane centrally dividing the thread groove (8) and the side (11) opposite the guide groove (8).

Abstract: A needle module and needle bar is disclosed in which tufting tools are cast at one end into a plate-shaped module basic body having a plane face bearing on a plane bearing face of the bar and at least one perforation, through which a fastening screw can engage and be screwed into the bar, wherein the module is secured positively to the bar in the vertical direction by means of a first groove-and-tongue joint and in the horizontal direction by means of a second groove-and-tongue joint and is held non-positively in the direction of the bar by means of the fastening screw.

Abstract: In a bar with modules for tufting tools, in particular a needle bar with needle modules, in which the tufting tools (3) are cast at one end into a plate-shaped basic body (1) of the module, at least one groove (9) running horizontally is worked in the bar (4). There extends from a plane face (2) of each module at least one moulding (7; 8) which projects perpendicularly to this face (2) and which engages into the groove (9) of the bar (4) and, alone or jointly with further mouldings (7; 8), holds the respective module fixedly in terms of rotation in the bar (4).

Abstract: A combination of a bar having a bore therein, and a tufting tool module for the bar including a bore extending therethrough. A fastening screw extending through the bore of the module, and threaded into a cooperatively threaded portion of the bore of the bar. The module has a plate shaped body having a first plane face which bears against a first plane face of the bar, and is urged into contact with that face by the fastening screw. There is a first stop strip extending from the first face and along a first edge of the module body. The first face of the module body is locked in a given angular position relative to the fastening screw. In one embodiment a first collar which projects from the first face of the module body, is positioned annularly around the bore and received in the bar with a locating fit. The first stop strip is closely adjacent the surface of the bar.

Abstract: An improved sinker and tufting tool module combination. The sinker, especially a needle sinker, is provided with a horizontally extending groove and a threaded bore. The tufting tool module, especially a needle module, has tools secured to a lower edge thereof and is provided with a through bore for receiving a securing screw. The module has a first, sinker facing surface and on that surface, there is provided a moulding which extends perpendicularly from that surface and engages the groove in the sinker. The module is supported on the sinker so that it can be pivoted about an axis running in the longitudinal direction of the sinker. Devices are provided for locking the module to the sinker in a desired angular position. By this arrangement, the position of the module can be adjusted, slightly, so that it may be precisely adapted to prevailing conditions.

Abstract: In a module with tufting tools, especially needles the tufting tools are cast with one end in a plate-shaped base The length of the base corresponds to a multiple of the center distance of the cast-in tufting tools. The base has at least one opening which is in the form of a slot running perpendicular to the locating strip(s), which is open to the upper edge of the base. The base can be of symmetrical design and have a locating strip both at its front and at its rear locating face, serving to precisely position the module on a bar. The module and thus also the tufting tools cast into it can thus be used in two different rotational positions.

Abstract: A module with tufting tools, in particular needles, in which the tools (2) are cast in a basic body (1) the length of which is equal to a multiple of the mean distance between the tufting tools (2) cast into the basis body, is provided on its rear face (3), which can be attached to a bar, with a bearing ridge (5) and recesses and on its front face (4) with a receiving shoulder (7) and projections. The module is traversed lengthwise, from the rear face (3) to the front face (4), by an elongated hole (9). The recesses on the rear face (3) are formed by the spaces between a countersunk row (6), of teeth (10) which are identical and equidistant from each other and have straight flanks. The projections on the front side are formed by a projecting row of teeth (8), the teeth (12) and the spaces (13) between the teeth of the row of teeth (8) match the spaces (11 ) and the teeth (10), respectively, of the row of teeth (6).

Abstract: In a tufting needle with an eye (7) elongate in the direction of the needle axis (8), one side face is bevelled at one longitudinal edge by a land (6) and at the other longitudinal edge by a bias grind (14) reaching into the zone of the eye. The uppermost zone of that edge (9) of the eye, which zone is furthest from the needle point (13), is offset towards the land (6) relatively to the central axis (8) of the eye (7) to facilitate trouble-free co-operation between the looper (2) on the one hand and the needle and yarn (5) on the other hand.

Abstract: In a tufting needle for tufting machines comprising an operative shank portion of oblong cross-section and containing a thread guide and eye and an anchoring shank portion by which the needle is embedded in a needle module, said anchoring portion is of elliptical or rhombic cross-section and the major axes of the cross-sections of both portions are disposed in substantially the same plane.
