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 (p.sub.min) is set and the number workstations simultaneously supplied with additional negative pressure is limited so that the minimum negative pressure (p.sub.min) is always met. In accordance with the invention, a sub-negative pressure (p.sub.sub) is specified which is below the minimum negative pressure (p.sub.min) 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 (p.sub.sub) is always met.

A wiring machine includes a lever group and magnets. The lever group includes a plurality of lever arms which are spaced apart and a plurality of rotary shafts on each of which one lever arm is mounted correspondingly so as to facilitate the rotate rocking motion of the lever arms. One end of each lever arm is provided with a wire gripper and the other end is provided with an attraction head. The magnets are arranged in association with the plurality of attraction heads.

A textile machine includes a plurality of workstations adjacently situated in a longitudinal direction of the textile machine, the workstations combined to form multiple sections wherein each section includes one or more of the workstations. A plurality of electrical supply units supply electrical energy to the workstations, wherein one of the electrical supply units is assigned to each section or to each workstation. A cooling arrangement includes at least one coolant circuit configured with the electrical supply units such that waste heat generated by one or more of the electrical supply units is absorbed by a coolant within the coolant circuit and transported to a common discharge area of the textile machine.

In a method for producing a musical string, wherein at least one first winding element is wound on a string core of the musical string in the form of a helical line around the string core, it is proposed that during the winding of a first longitudinal section of the string core using the first winding element, a first pre-tension is applied to the string core, and during the winding of a second longitudinal section of the string core, which is different from the first longitudinal section, using the first winding element, a second pre-tension, which is different from the first pre-tension, is applied to the string core.

A method determines an electrical characteristic at a spinning machine or winder, wherein the electrical characteristic is one or both of electrical power and electrical energy consumption. The spinning machine or winder includes a plurality of adjacently arranged workstations that each include an electrical working element. A total electrical characteristic for the spinning machine or winder is measured with a central measuring unit. The workstations are subdivided into at least two production groups that operated independently of one another. A distribution key is defined and used to calculate the electrical characteristic specific to each of the production groups by allocating the total electrical characteristic to the production groups with the distribution key. The specific production group electrical characteristics are displayed at the spinning machine or winder and transmitted to a computer that is at a higher control level than the spinning machine or winder.

A method is provided for operating a suction device of a textile machine having a plurality of workstations wherein an air flow and a vacuum are produced with aid of the suction device. The method includes filtering the air flow with a filter element, and determining a loss of pressure or volume flow at the filter element. Based on the loss of pressure or the volume flow, an actual value is calculated for present maximum vacuum-requiring operations of the workstations that can be simultaneously executed. Based on the number of operating workstations, a setpoint value is determined for the maximum vacuum-requiring operations of the workstations that can be simultaneously executed. The setpoint value is compared to the actual value for control of the suction device.
