ABSTRACT:
A method for winding yarn on a cross-and-cone wound bobbin, the yarn being ed at a constant speed from a spinning frame or from a texturing machine and temporarily held in a receptacle and then wound on the bobbin at a variable and controlled speed. The speed of winding is controlled by changing the position of the point of contact between the bobbin and a drive element, or by periodic breaking of contact between the bobbin and the drive element, the drive element rotating at a higher speed than the speed at which the yarn is fed, or by changing the rotational speed of the drive element in accordance with the deviations from the value of required filling of the receptacle with yarn. The apparatus includes a vacuum receptacle for the yarn equipped with a measuring sensor, a controller of the bobbin position including a pneumatic power device and a slider in which a holder of a cone element is rotably mounted, the controller being mounted on an arm and being connected with a piston rod of a power device. An analog system connects the measuring sensor with the power device.
