The system comprises at least one treatment unit being configured to dispense one or more coating substances onto the at least one thread when activated and a thread speed sensor being driven by the motion of the at least one thread. A method is further provided. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A system for in-line treatment of thread for use with a thread consuming device, comprising: a treatment unit comprising at least one discharge device being configured to dispense one or more coating substances onto the at least one thread when activated; a thread speed sensor configured to measure a speed of the at least one thread, wherein the thread speed sensor is arranged just before or just after the discharge device, and a control unit being, wherein the control unit is configured to: receive speed data from thread speed sensor, control the operation of the at least one discharge device of the treatment unit based on said received speed data. ### Claim 22 (depends on 21) The system according to claim 21, wherein the thread speed sensor is arranged upstream said at least one treatment unit. ### Claim 23 (depends on 21) The system according to claim 21, wherein said control unit is configured to control activation of said treatment unit based on a predetermined operation scheme of said thread consuming device. ### Claim 24 (depends on 21) The system according to claim 21, wherein the thread speed sensor comprises a rotational sensor being driven by the motion of at least one thread. ### Claim 25 (depends on 24) The system according to claim 24, wherein the rotational sensor comprises a pulley. ### Claim 26 (depends on 25) The system according to claim 25, wherein the thread speed sensor further comprises an encoder being in operative communication with the pulley. ### Claim 27 (depends on 26) The system according to claim 26, wherein the encoder is a rotary encoder. ### Claim 28 (depends on 21) The system according to claim 21, further comprising a light detection system for illuminating the at least one thread in order to receive light which is reflected from the at least one thread when said at least one thread is illuminated, wherein the light detection system is arranged downstream the at least one treatment unit along the travel direction of the at least one thread. ### Claim 29 (depends on 28) The system according to claim 28, wherein the light detection system comprises at least one light source and an optical sensor. ### Claim 30 (depends on 28) The system according to claim 28, wherein the coating substance is a colouring substance, and wherein the system further comprises a control unit configured to: receive data from the light detection system, and determine the colour of the colouring substance that has been dispensed to a specified section of the at least one thread based on said received data. ### Claim 31 (depends on 30) The system according to claim 30, wherein the control unit is further configured to: compare the determined colour against a predetermined colour scheme, and if said determined colour and the predetermined colour scheme does not match within a tolerance limit, generate an alarm signal and/or adjust the operation of the treatment unit. ### Claim 32 (depends on 21) The system according to claim 21, wherein the treatment unit comprises a plurality of nozzles arranged at different positions relative the at least one thread, said at least one thread being in motion in use, each nozzle being configured to dispense one or more coating substances onto the at least one thread when activated. ### Claim 33 (depends on 32) The system according to claim 32, wherein the nozzles are inkjet nozzles. ### Claim 34 (depends on 21) The system according to claim 21, further comprising a thread consuming device. ### Claim 35 (depends on 34) The system according to claim 34, wherein the thread consuming device is an embroidery machine, a sewing machine, a knitting machine, a weaving machine, a tufting machine, a thread winding machine, and or any combination thereof. ### Claim 36 A method for in-line treatment of at least one thread for use with a thread consuming device, comprising: providing a treatment unit comprising at least one discharge device being configured to dispense one or more coating substances onto the at least one thread when activated providing a thread speed sensor configured to measure a speed of the at least one thread, wherein the thread speed sensor is arranged just before or just after the discharge device, and a control unit being, wherein the method further comprises: receiving speed data from thread speed sensor, and controlling the operation of the at least one discharge device of the treatment unit based on said received speed data. ### Claim 37 (depends on 36) The method according to claim 36, further comprising: controlling activation of said at least one treatment unit based on a predetermined operation scheme of said thread consuming device.
