Abstract: The invention relates to a process and a device for monitoring the quality of a strip (37, 44, 50) made of textile fibres which is moved in its longitudinal direction. In order to create a device and a process which allow flaws in a strip to be dealt with in a targeted manner and which facilitate the production of a strip which is as free as possible of variations in the cross-section or mass, variations in the mass of the strip are to be continuously detected and converted into an electrical signal. This signal should also be compared with a plurality of predetermined limiting values, limiting values for variations transverse to the longitudinal direction being provided and limiting values for variations in the longitudinal direction of the strip being provided.

Abstract: The invention relates device for drawing an elongated textile intermediate product (2), such as a staple fiber fleece or sliver, into a receiving element (3) of a textile machine station. In order to be able to take in, transport onwards and twist elongated textile intermediate products, there is to be provided a guide (1) for the intermediate product. This has a guide face (13) and nozzles (7, 8) for injecting a fluid, e.g. compressed air, along axes (10, 11) which are inclined in relation to the axis (12) of the guide face. The exit apertures of the nozzles are at a distance from the intermediate product.

Abstract: A device for measuring the mass of fiber slivers contains an entry part for the fiber sliver to be measured and a measuring part adjoining the entry part. Arranged on the measuring part are two measuring members working on different measurement principles, specifically a so-called fiber-sliver mechanically, and so-called active-pneumatic measuring member for measuring the pneumatic pressure generated by the fiber sliver at a contraction. In addition to measuring the mass of fiber slivers, the device can be used for obtaining a characteristic variable for their composition or for separate regulation and monitoring in a control stage.

Abstract: A spinning machine has a plurality of spinning stations and a transport installation including a conveyor belt for receiving ready spun spinning bodies and for conveying them to a container in a predetermined sequence. A thread sensor scans the spinning stations with respect to thread breaks and supplies corresponding data to an evaluation device. This device has a memory in which the thread break number and thread break standstill time of the individual spinning bodies are stored and expressed on call. These stored values are used to control a sorting device which operates in such a way that the spinning bodies are sorted into different containers according to their thread break number and thread break standstill time. A quality selection of the spinning bodies may, therefore, be made in that, for example, all spinning bodies which are produced without any thread breaks and with the same yarn length are judged as being perfect and may be directly further used.
