  • Apparatus for the guidance of thread in a spinning station
    Patent number: 6276122
    Abstract: The invention concerns an apparatus for the guidance of a spun thread in a spinning station, wherein, after the thread has been produced, it runs in its travel direction through a withdrawal device, a measuring instrument, and a traversing apparatus. The invention makes possible a smooth and stable thread guidance between the withdrawal device and the traversing apparatus, so that both the run of the thread and the quality of wound filament of the thread can be monitored. Between the measuring instrument and the traverse apparatus, at least one deflection roll is provided.

  • Open-end spinning machine
    Patent number: 5431006
    Abstract: An open-end spinning machine with a machine frame with at least one section. The latter is provided for each longitudinal machine side with a rigid structural unit which consists of several longitudinal structural elements and two end walls. Intermediate walls are provided at least between two adjoining pairs of spinning stations. These intermediate walls are rigidly connected to the longitudinal structural elements as are the intermediate walls, whereby the groups of technological spinning elements, including the parts of drive units and the winding mechanisms are attached to longitudinal structural elements and/or to the intermediate walls. The end walls of the two structural units are connected to each other in pairs.

  • Process to detect and count yarn defects having a color background and a camera
    Patent number: 5420439
    Abstract: A process and device to detect and count yarn defects in a yarn segment including a camera (5), a computer (8) and an image processing program. The yarn (30) is illuminated with an intensity dependent upon the thickness of the yarn (30) and is photographed by the camera (5). The photographed image is digitalized in the computer with the image processing program and low-contrast points are filtered out. The remaining points are gathered together into coherent areas the sizes of which are classified into predetermined size classes and are stored.

  • Process and device for pneumatic introduction of fibers into a spinning machine
    Patent number: 5343686
    Abstract: A process for introducing a fiber sliver into a fiber processing machine which has an openable sliver feeding device and a sliver introduction funnel and a sliver injector, comprising the following steps: opening the openable sliver feeding device, grasping the leading end of the sliver pneumatically into and through the sliver introduction funnel and into the opened feeding device and closing the sliver feeding device on the sliver. The invention also includes a device for carrying out the process.
