    摘要: A device to enable yarn to be fed for textile applications and the relative turns to be separated. The device includes a wheel/drum directly or indirectly motorized for rotation about its axis, the wheel/drum presenting in its lateral surface a series of slits to receive relative blades the projecting profile of which enables the yarn turns wound on the wheel/drum to advance. The blades form an assembly which rotates together with the wheel/drum but about an axis having an inclination and/or an eccentricity relative to the axis of the wheel/drum, such that the profile projection of the blades from the relative slits varies gradually along the perimeter of the wheel/drum, from a minimum to a maximum, to then return to a minimum, but remains constant with time. The blades have a length to be able to receive all the yarn turns which concern the device.

    摘要: A device (1) for feeding a yarn (F) to a textile machine (T) comprises a housing (1A) with which a rotary member (2) is associated to cooperate with the yarn (F) unwinding from a package and directed, on leaving the device (1), to said machine (T) where it is processed, correct feed of the yarn (F) being monitored by feed control means (5) associated with said housing (1A) in accordance with at least one measured parameter related to the rotary member (2) or to an intrinsic characteristic of the yarn (F) such as its tension or its feed velocity, a yarn cutting member (13) being provided. This is connected to and controlled by said control means (5) on the basis of the measured parameter of the yarn (F), said cutting member (13) being activated by said control means (5) to cut the yarn (F) whenever the parameter monitored by said means has a value exceeding a predetermined required value.

    摘要: A swivel arm (14), which is operated by a motor (15) driven by a control unit (UC), winds yarn loops forming a weft reserve (RT) on a stationary drum (12). A position detector (20) controls the angular position and the speed of the swivel arm, and comprises an annular permanent magnet (22) which is keyed to the shaft (15a) of the motor and is diametrally magnetized with a sinusoidal distribution of the magnetization. A pair of Hall sensors (24, 26), which are angularly spaced at 90° from each other about the axis of the magnet, are arranged near the magnet for detecting the diametral component of the magnetic field generated by the magnet, and are connected for sending signals to the control unit, which is programmed for calculating the absolute angular position (Ω) of the motor shaft on the basis of the signals from the Hall sensors.

    摘要: The invention relates to a yarn feeding device (B) of a weaving machine (W), comprising at least two yarn feeding appliances (F1, F2) delivering the same yarn quality in a weft mixing process. Each yarn feeding appliance comprises a variable speed control system (C), a sensor arrangement (6) which supplies control signals for the size of the reel, and at least one fault sensor (Z1, Z2), by which means a fault signal (X) indicating a change in the weft mixing condition, e.g. a yarn break in the upstream from the reel, can be emitted. According to the invention, a fault signal transmission link (Q1, Q2) is provided by each yarn feeding appliance for the speed control system (C) of each other yarn feeding appliance, and an over-regulation routine (6) is provided in each speed control system (C), said routine enabling the speed to be increased before the change in the weft mixing condition, by means of the fault signal (X), independently from the control signals of the sensor arrangement (6).

    摘要: A micro-controller (MC) receives pulses ( mp0, mp1 , ...) related to the revolving speed of the motor, and generates a stop signal (LS) for disabling the loom when the time between two successive pulses exceeds a predetermined maximum time (ML). Such maximum time (ML) is calculated by the micro-controller as a value that is inversely proportional to the operating speed of the pre-feeder/pre-measurer, preferably to the synchronization frequency set for the motor ( fs ) or to the weft-consumption rate (Vmc), at least over a main span of its range.
