Abstract
A process for determining the optimum winding speed to obtain greater productivity of an automatic coner machine fed with a certain type of yarn. Acceleration and braking values are optimized, as well as various production parameters of the devices along the path of the yarn. For example, the yarn tension, the slub catching level, and the amount and nature of the lubricant, or paraffin, applied to the yarn. The collection front of the machine is subdivided into various winding sectors. Each sector is preset, by means of a central microprocessor unit, to operate at a winding speed, and with operating parameters which are partially different from, and partially equal to, the operating parameters of the other sectors, according to a program pre-set in said central unit. The central microprocessor unit processes the data received from each individual sector, and compares them to each other to define and display the values of the operating parameters. This allows the highest productivity to be obtained in the yarn winding process.
