Abstract

A method for operating a textile machine with several identical workstations which each have a basic requirement for negative pressure for regular production operation and an additional requirement for negative pressure following an interruption to production at the workstation, and with a vacuum system with limited suction force to exert the negative pressure on the workstations. A minimum negative pressure (pmin) is set and the number workstations simultaneously supplied with additional negative pressure is limited so that the minimum negative pressure (pmin) is always met. In accordance with the invention, a sub-negative pressure (psub) is specified which is below the minimum negative pressure (pmin) and, if a specified event occurs, the number of workstations simultaneously supplied with additional negative pressure is temporarily limited so that the sub-negative pressure (psub) is always met.
