Apparatus for pneumatically feeding at least one spinning preparation machine, for example a carding machine or cleaner |
摘要 |
Automatic modification of volumetric air flow in an apparatus for pneumatically feeding a spinning preparation machine, by means of fiber-flock charging shafts located upstream of individual spinning preparation machines and connected to a pneumatic fiber-transporting line, the transporting line connected by way of a fiber material feed fan to the fiber-processing machine upstream. A set of characteristic curves describing air flow is stored in a characteristic curve set element; a measurement signal for the pressure difference at the fan and values relating to rotation of the fan are ascertained in a computer unit. The computer unit determines value of the volumetric air flow from the characteristic curves. In the event of departure from a desired value for the volumetric air flow, the operating point for the speed of rotation of the fan is displaced to the desired value.
