Device for control of value of hardness of textile threads includes executive device, measuring block, rigidity calculator that includes filter and amplitude measuring device connected to division block. Device has as well cam drum that rotates from micro-electric motor, transformer of force of pressure of textile threads on drum to electric signal, amplifier of that signal load of which is noise filter and constant component. Output of filter is connected to output of amplitude measuring device, divider with two outputs and one input where first input is output of amplitude measuring device, second input is output of master of respective elongation of textile threads and its output is connected to input of register of rigidity of threads. |
