A knitting machine may include a needle bed and a carriage that is movable along the needle bed. The carriage may be configured to engage at least one feeder to move a dispensing area of the feeder along the needle bed while dispensing a yarn, where the carriage includes an interface for providing power to an auxiliary component.

A method monitors/controls unwinding and supplying thread from a supply device to a textile machine. The supply device includes a control unit and a thread collection and supply unit moved by a motor. A first sensor detects first data indicative of a current driving torque applied to the collection and supply unit. A second sensor detects second data indicative of a current tension value of thread supplied to the textile machine. A first indicator representing driving torque values is calculated, each variation of the first indicator representing a variation of the driving torque value to compensate for a deviation of the first data. A second indicator is calculating representing tension values applied to the thread supplied to the textile machine. Each variation of the second indicator representing a deviation of the second data. Based on the indicators, malfunctions in the unwinding and supply of thread are detected and signaled.

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).

A system for detecting filament and needle breakage, including: an image acquisition module, an image processing module and a host computer detection module. The image acquisition module includes a light source, a camera and a lens. The image processing module includes a preprocessing submodule and a detection model. The host computer detection module includes a shutdown control-data interaction submodule of a warp knitting machine, a sensor control board, and a system operation interface. The image acquisition module captures a blanket knitting image at a knitting mechanism of the warp knitting machine. The image processing module pre-processes the blanket knitting image and detects filament and needle breakage. The host computer detection module controls a textile device according to detection results to generate an alarming information. A detection method implemented by the system is further provided.
