Method for controlling the consumption of yarn in a weaving process
10662557 · 2020-05-26 · ·

A textile machine receives a plurality of yarns from respective feeders, each provided with a control unit that calculates, for each garment produced, the amount of yarn consumed (YCmeas) and compares it with a reference consumption value (YCref). If the difference exceeds a preset limit value (% max) that indicates an anomaly, then an alarm is generated. Periodically, the control unit calculates an average consumption value (YCmed) on the basis of a preset number (Nmed) of already-finished garments, and compares it with the reference consumption value (YCref). If the difference exceeds a preset threshold value (% maxmed), then the reference consumption value (Yref) is set to the average consumption value (Ymed).

Method and system for managing and controlling the feeding of at least one thread to a textile machine as a function of the operating step of the latter
10544529 · 2020-01-28 · ·

Method and system for managing and controlling feeding of at least one thread to a textile machine as a function of the machine operating step in product production or thread processing, such production or processing providing for a succession of steps corresponding to obtaining product parts or treating thread. The thread fed to the machine by a feeder at constant tension and/or speed and/or controlled by a sensor which monitors sliding or inherent characteristic thereof such as tension, speed, diameter, quantity and color. The sensor and/or feeder controlled by a setting controller. The setting controller receiving synchronization signals from the machine and detectingaccording to the latterthe operating steps and thus product or production status. The operation setting programmed as a function of operating steps. The machine generates a unique synchronization signal, for each operating step, independently from step length.

DEVICE FOR PROCESSING THREADS OR YARNS OF TEXTILE FIBERS

A device for processing threads or yarns of textile fibers includes a supporting structure for at least one spool for feeding a thread or a yarn of textile fibers and at least one textile machine, associated with a control panel, which uses the thread or yarn unwound from the at least one feeder spool. The device also includes a supporting structure for weighing the feeder spool, which is functionally connected to a control and actuation device. The weighing device is associated with protection elements adapted to avoid excessive stresses of the weighing device during the operations for loading and/or unloading the feeder spool onto and/or from the supporting structure.
