Abstract: The invention relates to a pin assembly which keeps single-piece, two-piece or multi-pieced yarn processing elements, especially yarn interlacing spinnerets or thermal treatment elements, in an exact position during an entire service life, despite the extreme effects of preparations used. Instead of a traditional soldered joint or an adhesive connection, mechanical clamping means are used to fix the dowel pins to one part of the spinneret. Fixation of the dowel pins is not affected by heat or chemical preparations. The clamping means consists of a simple clamping ring holding the dowel pin in position directly inside the body of the spinneret between the clamping pin and an after-body. The novel positioning solution can be used with individual parts of spinnerets, parts of spinnerets in machines or multiple parts of spinnerets. The dowel pins enable the entire spinneret to be substantially miniaturized and allow narrow separation between various yarn runs, which was previously impossible.

Abstract: A method of air jet texturing is described wherein the intensity of texturing is proposed to be increased in that an air flow exceeding Mach 2 is obtained by the design of the nozzle duct. The total opening angle of the nozzle duct (11) directly in front of the texturing zone is designed to be greater than the ideal Laval angle with an effective length which is preferably a multiple of the smallest diameter of the nozzle. This predominantly improves the quality of texturing, quite particularly at higher production rates. These can be increased into the range of 600 to 1000 m/min and higher. It has surprisingly been found that the novel nozzle core (10) can be designed so that it has all advantages of the novel invention and can be used as a substitute for prior art nozzle cores. The same applies to the complete texturing head as the novel invention can be used within the same geometric external dimensions, the same air pressure and the same quantity of air.

Abstract: An apparatus and method for the manufacture of a mixed yarn consisting of two components, continuous filament yarn and staple fibers. The mixed yarn is manufactured by an air jet texturing process. It has been possible to bind the staple fibers undisplaceably into the yarn, and this is ensured by the loops on the continuous filaments produced during texturing. Owing to the formation of a suction zone of the airstream directly before the beginning of actual texturing, the staple fibers can be sucked in and can be blended into the interior of the yarn and can be secured firmly in the yarn by the loops. The invention relates to a new method of manufacture and to an apparatus, or an entire machine, with which the known loop yarn or the new mixed yarn can now be manufactured selectively.

Abstract: A device for securing cloth-forming parts to the sley (1) of a loom comprises, to receive fixing screws (4), a clamping element (51, 52) in the form of a slide block. The clamping element bears directly on the sley on only one side of a plane which extends parallel to sley length and through the axes of the screws. Consequently, the securing elements (4, 51, 52) can be introduced preassembled into the corresponding groove (15) in the sley (1), so that assembly is rapid. Depending on the construction of the device it has the advantage over known solutions of the problems of simpler fabrications and low mass of the sley holder.

Abstract: In a device for securing cloth-forming parts (19) to the sley of a loom, two clamping members (71, 72, 91, 92) directed towards one another wedge-fashion are tightened on one another by a clamping screw (6), the clamping members bearing on one side in the sley by way of clamping surfaces (140, 141) disposed at an inclination to the screw axis. At least one of the parts bears on its other side directly on the cloth-forming part (19). The second clamping member (71, 72) can bear on its other side on the first clamping member (91, 92). Consequently, the securing elements (71, 91, 6) can be introduced preassembled into the corresponding groove (16) in the sley, so that assembly is rapid.

Abstract: Vacuum support for a burst protection device of graphite, which support is a graphite disc formed by a multiplicity of graphite rings, each of which consists of at least two parts and has a prismatic cross section, the prism surfaces being inclined relative to the plane of the disc.

Abstract: A hard gelatin capsule, especially for medicaments, having a cylindrical body and a cylindrical cap that telescopes over the open end of the body in which the interior surface of the cap, which overlaps the body, is provided with toothlike projections spaced around the circumference thereof to lock the body and cap against relative axial and rotational movement. In a preferred form of the invention the projections have gently-sloping side walls in both the lateral (circumferential) and longitudinal (axial) directions, which facilitate removing the cap from the dipping pin on which it is formed.

Abstract: A drive device for a carrier of a filling-thread gripper head on a loom in which the carrier is moved back and forth by a drive wheel that is rotated alternately in opposite directions through a planetary gearing arrangement, the operation of the drive device being synchronized with the movement of the batten and harness of the loom.
