Problems solved by technology
When the amount of finishing agent applied is small and thus the conveying speed is small, the temperature drift may be so large that the difference in the sensed signal does not have a significant edge (pulse) sufficient to reliably determine the presence of finishing agent

Embodiment Construction
[0037] The accompanying drawings simply illustrate the subject matter of the present invention and are not to scale. The individual components of the subject matter of the inventive solution are drawn in such a way that their structure is well represented.
[0038] exist figure 1 A schematic view of a finishing device (oiling device) according to the invention is shown in . The yarn 2 to be finished is unwound from a feed bobbin 3 in a bobbin position and is wound on a package bobbin 4 . Here, a certain application amount of finishing agent is applied to the running yarn 2 by means of a coating device 6 , which is positioned in the region of the spinning process of the yarn 2 and is designed as a coating nozzle. The finishing agent to be applied, ie the amount of finishing agent applied, is conveyed via a liquid line 8 into the application nozzle arrangement. The finishing agent is conveyed by means of a dosing system 11 controlled by a control unit 10 with, for example, a ...

Disclosed is a method for monitoring the presence of a finish on an applicator (6) when an amount of finish is applied to an advancing textile thread or yarn (2) by means of said applicator (6). The disclosed method comprises the following steps: - the amount of finish to be applied is delivered, especially from a storage vessel, through a duct (8) in the direction of the applicator by means of adosing system (11) for controlled delivery of the finish to be applied; - a progress of a first finish temperature is measured in a first measurement point on the duct by means of a first temperaturesensor (13); - a progress of a second finish temperature is measured in a second measurement point on the duct by means of a second temperature sensor (14); - the finish to be delivered is heated between the first and the second measurement point by means of a heater (16); and - the progress of the difference between the measured finish temperatures is determined, and the presence of the finish is monitored by evaluating the progress of the difference between the measured finish temperatures. The amount of delivered finish (25) is temporarily increased beyond the amount of finish to be applied during a certain interval by means of the dosing system (11) when the finish temperatures are measured.
Description
technical field [0001] The present invention relates to a method for monitoring the presence of finishing agents, especially oil (finishing agent monitoring method). This method is on a coating device. When applied to a running textile thread or a running textile yarn, the invention also relates to a device for carrying out the method. The presence of finishing agent also refers in particular to the presence of finishing agent, ie the flow velocity of the finishing agent flow. The finishing agent monitoring method has the following method steps: [0002] - by means of a dosing system, the amount of finishing agent to be applied is delivered from a storage container via a liquid line in the direction of the coating device for controlled delivery of the finishing agent to be applied, [0003] - measuring a time profile of the temperature of the first finishing agent at the first measuring point on the liquid line by means of the first temperature sensor, [0004] - measuring ...
