Spinning preparation machine with outlet regulation

摘要

Spinning preparation machine, in particular track, carding machine or combing machine, with a drafting device (4) for drawing and optionally doubling of presented fiber material (FB), wherein the drafting device (4) has an upstream pair of rollers (5) and a downstream pair of rollers (7) a sensor (2, 3, 20) in front of the drafting device (4) for measuring the fluctuations of the fiber material (FB) in terms of mass, thickness or density, with a processor device (22) connected to the sensor (2, 3, 20), which, due to the sensor signals, actuates the downstream pair of rollers (7) in order to change their rotational speed in the form of an outlet regulation, with the drafting unit (4) downstream calendering rollers (14) for drawing the drawn fiber material (FB ') out of the drafting arrangement (4) and the latter Further transport, and with a storage device (16, 17) with a turntable (16) for depositing the fiber material (FB ') in a pot (18), characterized in that the downstream ge roller pair (7) and the Kalanderwalzenpaar (14) by driving by means of the processor device (22) at least temporarily changed speeds are driven, the storage device (16, 17) with less dynamics or substantially without speed change compared to the downstream pair of rollers (7 ) and the Kalanderwalzenpaar (14) are driven.
