    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 method for winding a synthetic yarn coming from an extruder including the steps of connecting at least one yarn exiting from an extruder with at least one corresponding bobbin rotatable around a longitudinal axis thereof, on which the yarn is wound; rotating the bobbin by imparting a specific speed and/or torque to the bobbin; measuring a value of the tension acting on the yarn upstream of the bobbin; adjusting the speed and/or the torque to maintain the measured tension value substantially equal to a constant reference value of the tension.

    摘要： A storage yarn feeder (1) comprises a body (2) having a portion or drum (3) onto which winds a yarn (4) forming at least one coil, said yarn (4) coming from a reel, being provided with a braking organ (8) cooperating with said drum (3) to brake the yarn (4) leaving said drum (3), said braking organ (8) comprising braking means capable of cooperating with the yarn (4) when it detaches from the drum (3) as it leaves the feeder and heads towards a textile machine. The drum (3) comprises a first (3A) and a second portion (3B), the latter being capable of supporting the yarn (4) and being separable from the first portion (3A) so as to be capable of being replaced, said first portion being connected to the body (2) of the feeder.

    摘要： A device for feeding yarn to a textile machine, including a main body defining an entry portion and an exit portion for yarn; a rotatable drum for winding the yarn originating from the entry portion and a motor connected to the drum for rotating the drum; a control member active at least on the motor to regulate its torque and velocity; exit portion being selectively switchable between a first configuration in which it defines a free exit section for the yarn, through which the exiting yarn defines a closed path about a rotation axis of the drum, and a second configuration in which it defines a limited exit section, through which the exiting yarn defines an open path.

    摘要： A device (1) for cutting a textile yarn (F) during its feed to an operator element such as a textile machine for its processing or a member for feeding it to such a machine, said device (1) comprising a blade member (21) inserted into a housing (2) presenting at least one aperture (10) for passage of said yarn (F), said blade member (21) being carried by a movable support element (20) subjected to actuator means for its movement, said movable support element (20) being able to assume two working positions, a first position in which the blade member (21) is spaced from the yarn (F) and a second position in which said member cooperates with the yarn (F) and cuts it. The actuator means comprise bistable electromagnetic means (12), a spring (25) mounted about the movable support member (20) urging the blade member (21) into the cutting position.
