<p>A process is disclosed, which makes it possible the optimum winding speed to be determined, in order to obtain a greater productivity, on an automatic coner machine fed with a batch of a certain type of yarn. Also the values of acceleration and braking are optimized, together with the various production parameters deriving from the functions of the devices the yarn meets along its path, such as the yarn tension, the slub catching level, the amount and nature of the lubricant, or of the paraffin, applied to the yarn. The whole collection front of the individual machine is subdivided into various winding sectors (2), and each sector is preset, by means of a central microprocessor unit (6), to operate at a winding speed, and with operating parameters which are partially differentiated from, and partially equal to, the operating parameters according to which the other sectors (2) operate, according to a program pre-set in said central unit (6). This latter processes the data received from each individual sector (2), and compares them to one another, in order to define and display the values of the operating parameters, which make it possible the highest productivity to be obtained in the yarn winding process.</p> |
