Abstract: 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.

Abstract: The invention relates to a process and apparatus for the random storage of tubes stacked on top of each other in a tube magazine, and for the transfer of the tubes at a transfer position to a conveyor. The tubes are stored randomly in the magazine with their longitudinal axes essentially parallel to each other. Tubes are separated between the transfer position and the magazine and are conveyed out of the magazine in the axial direction.

Abstract: In a textile machine, the machine frame is provided with frame walls made of sheet metal, each of which being made as a bearing element. For this purpose the frame walls are provided with 90 degree offset edges and are connected by combined plug-in and screw connections to connection elements and via the latter to at least one additional frame wall and receive structural and function elements by additional combined plug-in and screw connections.

Abstract: The invention relates to a process and to a device for the cleaning of a textile machine belt by means of a suction pipe. The belt is taken through the suction pipe and is subjected to suction. The suction pipe is provided with two slits for that purpose, by means of which the suction pipe surrounds the belt.
