Method for operating a textile machine and a textile machine

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 a workstation, and wherein the textile machine comprises a vacuum system with limited suction force to exert the negative pressure on the workstations,

• whereby a control unit is present and is used to specify a minimum negative pressure (pmin), wherein, at said minimum negative pressure (pmin), an absolute value of the minimum negative pressure (pmin) is at its lowest level during standard operation, and wherein the control unit is designed so that the number of workstations simultaneously supplied with additional negative pressure is limited so that the minimum negative pressure (pmin) is met,
• characterised in that,
• a sub-negative pressure (psub) is specified at the control unit, wherein an absolute value of the sub-negative pressure (psub) is below the absolute value for the minimum negative pressure (pmin), and
• that the control unit is designed so that, 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 met.
