Abstract
The warp threads (Ka) are clamped as a thread layer, are divided off individually from this and are stretched with a simultaneous measurement of the tensile force and/or stretching. These operations take place before the weaving process in a step of the weaving preparation process in which the warp threads are in the form of a prepared warp-thread layer. The device contains means (1, 2) for clamping the warp-thread layer, means (4) for dividing off the warp threads and means (FP) for measuring the tensile force and/or stretching of the divided-off warp threads, the means (1, 2) for clamping the warp-thread layer forming an integral part of a warp preparation machine, preferably of a knotting unit or of a drawing-in unit.
