Abstract:
A method for warping with a cone sectional warper that winds thread on a warping drum portion of the warper, the method comprising the steps of:providing a support for a thread guide comb adjacent the drum, the support being movable in a direction parallel to an axis of the drum;moving the support and drum relative to one another parallel to the drum axis to move the comb in response to a growing wind thickness and predetermined warping data;providing a roll on the support and positioning the roll spaced from the drum, the roll remaining spaced from the drum and wind thereon until the growing wind thickness of a first band of threads contacts the roll to start rotation of the roll;monitoring pressure of the roll in contact with the wind thickness on the wind and the rotational speed of the roll; andproviding a control device which records parameters including the rotative speed of the drum, and pressure of the roll on the wind, and detects deviation of the parameters from a predetermined setpoint, and initiates corrective movement of the support, and thereby the thread guide comb, to correct the pressure of the roll on the wind and to even out formation of the wind on the drum;wherein the monitoring of the roll is automatically started with a pulse tapped from the rotating roll.
