Abstract

The invention relates to a method for operating an air-jet spinning device following an interruption in spinning, a thread guiding channel, and an air-jet spinning machine comprising such a thread guiding channel. A drawing frame for drawing a fibre band is connected upstream, in the running direction of said fibre band, of the air-jet spinning device, and a single-motor thread draw-off arrangement for drawing off a thread spun by the air-jet spinning device is arranged downstream. According to the invention, following an interruption in spinning, the end of the spun thread, which is wound onto a take-up bobbin, is picked up by a suction nozzle and transferred to a thread end preparation device connected downstream of the air-jet spinning device in the running direction of the fibre band; the thread end is processed in said thread end preparation device and subsequently transferred into the region of the outlet opening of the spinning cone; the thread end is conveyed pneumatically to the inlet opening of the spinning cone and positioned there, inside the air-jet spinning device, at a distance in front of said inlet opening; and the drawing frame of the work station in question is lifted up and the fibre band is thus conveyed through a fibre band guide of the nozzle block into the region of the inlet opening of the spinning cone and joined to the prepared end of the spun thread.

Abstract

The invention relates to a method for operating a ring spinning frame (1). According to said method, fibers in the form of a sliver (3) are supplied to the ring spinning frame (1) and the sliver (3) is drawn in a drawing frame (2) between an input clamping line and an output clamping line and the fibers downstream of the output clamping line are twisted to a thread (4) by means of a spindle (5). According to the invention, the thread (4) is subjected to a mechanical vibration with a frequency of more than 10 Hz.

IPC Classes  ?

• D01H 5/18 - Drafting machines or arrangements without fallers or like pinned bars
• D01H 13/04 - Guides for slivers, rovings, or yarns; Smoothing dies

Abstract

The invention relates to a method for operating a textile machine (1) having a plurality of work stations (2), wherein state data of the electric drives (31, 41, 51, 61A, 61B, 91, 111) of the textile machine (1) are detected. According to the invention, the overall power consumption of the textile machine (1) is calculated as a function of the state data of the electric drives (31, 41, 51, 61A, 61B, 91, 111) and the overall power consumption of the textile machine (1) is displayed. The invention further relates to a textile machine (1) having a corresponding display (16). The display (16) of the total power consumption allows an energy-optimized parameterization of the textile machine (1).
