Method for controlling a warping machine and warping machine for implementing the method

摘要

A warping carriage (10) is displaced in accordance with the increasing lap thickness with respect to the warping drum (1). In the case of the first warp layer (26a), a prescribed forward movement of the warping carriage first warps a base lap (27) and then a measuring lap (28). The measurements obtained from the measuring lap (28) are used by a processor (31) to determine an adjusted forward movement of the warping carriage (10) for the rest of the lap (29). The subsequent layers (26b, 26c etc.) are copied from the first warp layer (26a). Warp data obtained when the data is input and/or from the adjusted forward movement, the free lap capacity and the already wound warp thread length of the base and measuring laps are used to calculate a maximum warp length and for purposes of comparison with a desired warp length which has been input. If the desired warp length exceeds the maximum warp length, the warping machine is stopped. A squeezer roll (22) can be provided, the effect of which can either be detected as early as the measuring phase or can be taken account of by the input of an assigned adjustment factor for the forward movement. <IMAGE>
