Method for warping with a cone sectional warper that winds up the threads (10) in bands on a sectional warping drum (11), in which a support (12) for a thread guide comb is displaced parallel to the warping drum (11) by a forward feed drive, corresponding to the increasing thickness of the wind and predetermined warping data, with the first band being sensed during a measurement phase by a roll (15) under contact pressure and with the sensed displacement travel being recorded as a function of the number of rotations of the warping drum (11), and with the roll being drawn back and pressing on the wind lap after the measurement phase upon further winding in accordance with a mean value obtained during the measurement phase. In order to even out the formation of the wind, the pressure of the roll on the wind lap is continuously measured and monitored during the measurement phase and/or during subsequent winding or copying, and the displacement of the support is corrected in case monitoring results differ from a predetermined set value.
A method for warping, the method comprising the steps of providing a cone sectional warper that winds up threads (10) in bands on a sectional warping drum (11), providing a support (12) for a thread guide comb (13) disposed parallel to an axis of the warping drum (11), and movable relative to the warping drum distances corresponding to an increasing thickness of wound threads and predetermined warping data, sensing a first band under contact pressure during a measurement phase and recording a sensed change of thread surface location as a function of a number of rotations of the warping drum (11), and with a regulating roll (15) being drawn back and pressing on a wind lap (16) after the measurement phase (23) upon further winding in accordance with a means value (v2′) obtained during the measurement phase (23), continuously monitoring pressure of the roll (15) on the wind lap (16) during the measurement phase (23) and during further winding and continuously correcting the disposition of the support when monitoring results differ from a predetermined set value.
Cone sectional warper comprising a thread guide comb (13) carried by a support (12), the support being displaceable on a machine frame (17) parallel to an axis of a warping drum (11), a motorized forward feed drive, a controller (24) for controlling said forward feed drive to produce relative motions between the warping drum (11) and the support (12) corresponding to the growth of wind lap thickness, a roll (15) for sensing wind lap circumference, displacement travel of the roll being stored by the controller as a function of the number of rotations of the warping drum (11), wherein the roll (15) is supported on at least one pressure sensor (18) that feeds data to the controller (24) during a measurement phase (23) and during further winding and copying, the controller being adapted to control the roll (15) in a corrective sense when the measured pressure differs from a predetermined set value, and wherein the roll (15) is pressed against the wind lap (16) by a servomoter.
