[0038] This prior document is silent on whether and how the data sensed in analog mode and the data sensed in digital mode influence each other when determining the characteristic of the filamentary material being measured (eg diameter)
[0039] Existing literature is also silent about the scan time of the product

Embodiment Construction
[0057] With reference to said drawings, in particular figure 2 , which shows a system 1 for detecting the characteristics of a thread F fed to a handling machine M. This line works together with an optical sensor 2, which in the example in the figures has an analog detection part 3 and a digital detection part 4, which are associated with a single container body 5, and the analog The detection part 3 and the digital detection part 4 are positioned in this body 5 at a short distance from each other. This makes it possible to have a detection system 1 (or detection unit or detection device) of very small size, so that this detection system 1 can be applied together with other identical systems on textile machines operating on hundreds of threads - such as knitting machines etc. - for each wire being monitored in
[0058] When said detection means 3 and 4 are also present in the body 5, the compactness of the system 1 can also be achieved due to the fact that there is only 1 l...

Method for detecting the characteristics of a textile or metal wire (F) fed to a manipulating machine (M), said method comprising generating a light signal impinging on the wire so as to be generated on an optical sensor device connected to a device (8) Shading, the means (8) for monitoring a characteristic of the wire based on electrical signals emitted by such sensor means according to the shadow produced by the wire (F) itself on said sensor means, said characteristic being a physical characteristic of the wire Such as the diameter of the wire, or the feed characteristics of the wire when it is in motion, such as the feed rate. The method comprises: the signal detected by said sensor device (2) comprises a signal detected in analog mode and a signal detected in digital mode, the signal detected in digital mode provides real-time calibration of the signal detected in analog mode, thereby An electrical signal characteristic of the monitoring line used by the monitoring device (8) is generated. An operating system according to this method is also claimed.
Description
technical field [0001] The invention relates to a method for detecting features of a textile or metal thread fed to a textile machine according to the preamble clauses of the main claim. A system for detecting the characteristics of such a wire and operating according to said method, as well as a sensor used in this system, according to the respective independent claims also comprise the object of the present invention. Background technique [0002] As is known, when feeding the wire into the operating machine, it is usually provided that at least one characteristic of the wire, which may be dimensional or feed-related (such as feed speed), is monitored by suitable sensor means . This allows the final product to leave the operating machine with characteristics and qualities that meet predetermined specifications. [0003] In this context the term "wire" is intended to mean both textile thread or yarn as well as metal wire; similarly the term "operating machine" covers both...
