MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202617080081 A) filed by Trtzschler Group Se on June 29, 2026, for Method For Controlling An Adjustable Working Pressure On A Combing Machine, And Combing Machine.
Inventors include Saeger, Nicole; and Friedrich, Roland.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The invention relates to a method for controlling an adjustable working pressure p on a combing machine (1) during a combing operation to produce a combed sliver (3). In a rolling time window (tstart, tend), a control and regulating unit (56) detects a temporal profile (90) of an actual value x detected by a measuring device (55) and analyses extreme values (91) of the temporal profile (90) of the actual value x, wherein the control and regulating unit (56) carries out a pressure adaptation process (100) if a predetermined number of the extreme values (91) lies outside a predetermined tolerance range (88) by the desired value (87), wherein the pressure adaptation process (100) comprises the following steps: a starting step (101), at which the working pressure p of the current pressure value pact is adjusted to an increased pressure value pinc, which is at least 1.2 times the current pressure value pact, or if the 1.2 times the current pressure value pact lies above the maximum value pmax, corresponds to the maximum value pmax; and an optimization step (103) if, at the working pressure p adjusted to the increased pressure value pinc, the extreme values (91) lie within the tolerance range (88) by the desired value (87), wherein the working pressure p is successively adapted and adjusted to an optimized pressure value popt, at which the extreme values (91) have a predetermined minimum deviation (89) from the desired value (87) and remain within the tolerance range (88) by the desired value (87); or a warning step (107) if, at the working pressure p adjusted to the increased pressure value pinc, at least one of the extreme values (91) lies outside the tolerance range (88) by the desired value (87). The invention further relates to a combing machine (1) which is configured for carrying out the method according to the invention.
