FIELD: textile, paper.
SUBSTANCE: device for uncoiling control of a web wound on a linen rod comprises of a turning rod, an actuator, a sensor and a controller. The rotating rod has a target position for receiving the web. The actuator is connected to the rotating rod and has a displacement axis. The sensor measures the position of the web in the transverse direction relative to the target position and transmits the input signal to the controller. The signal is transmitted if the position in the transverse direction of the web does not correspond to the target position. The controller sends an output signal to the actuator. The actuator moves the rotating rod along the axis of displacement so that the web remains substantially on the same line with the target position.
EFFECT: rapid detection and elimination of problems associated with the alignment of webs, elimination of web twisting.
