    摘要: Apparatus for the production of fixed point multifilament yarns with a whirling unit provided with a passage (15) through which the filaments to be whirled are driven and whirled together as at least one blasting nozzle injects gas into said passage. To obtain high filament feed rates and provide for the desired fixed points the blasting nozzle is in the form of a De Laval nozzle (20) whose jet is directed at an angle or perpendicularly to the longitudinal direction of the passage (15).

    摘要: The invention relates to a weaving loom which is provided with a selection device allowing the programmed selection of that weft thread among a plurality of threads which has to be inserted into the weaving shed by means of an insertion device. The selection device comprises a program control device and a positioning device controlled by such program control device, which positioning device moves the weft thread carrier so that only the selected weft thread is brought to an active position ready to be inserted into the weaving shed. The selection device comprises a microcomputer provided with a microprocessor, a read-only memory, a pattern computer and a keyboard intended for programming and operating. The positioning device is provided with electromagnets controlled by program control signals of the program control device, which electromagnets control the positioning of the weft thread carriers so as to move the weft threads from the passive positions to the active positions and vice-versa.
