A method and system detect and remotely manage sensors and/or devices for feeding textile and/or metallic yarns on textile machines. Each textile machine includes an electronic control unit electrically connected to the sensors and/or feeding devices for receiving identifiers associated with a sensor and/or feeding device, and data and operating parameters representing a sensor and/or feeding device operating state. A first communication system is associated with the electronic control unit. Wireless communication between the electronic control unit and a portable electronic device is by a second wireless communication system with a display interface. The electronic control unit transmits the identifiers to the portable electronic device. The portable electronic device processes the identifiers to generate menus with selectable entries associated with the textile machines. Each menu represents the number/type of sensors and/or feeding devices installed. The main menu is displayed with selectable entries on the portable electronic device display interface.

A textile machine adjustment method is provided. An operating speed of a textile machine within an operating range is set by a processor according to the basic information of the fabric. A motion image of the fabric and the vibration characteristics of the yarns are recorded by a video camera. The operating speed of the textile machine is adjusted at least once, and the vibration characteristics of the yarns is analyzed after each adjustment of the operating speed. Multiple correlation factor functions and the relative weights of the multiple factors related to the operating speed of the textile machine are recorded. The relative weights of the multiple factors are adjusted according to a yield quality of the fabric. When an expected value is met, the fabric continues to be produced at the current operating speed; otherwise, the relative weights of multiple factors are adjusted to correct the operating speed.

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 being 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.
