A machine controller for operation of a spinning mill machine includes a storage of an operating system code, container daemon code, and a plurality of container images. A processor section performs the following: provide a running operating system based on the operating system code; provide a running container daemon based on the container daemon code; and provide running containers based on the plurality of container images. The running operating system includes access functions for accessing the machine of the spinning mill and each one of a set of the running containers provides a service for controlling operation of the spinning mill machine. The running container daemon concurrently interfaces services of the running containers with access functions of the running operating system. The machine controller further includes an update service that updates the container images of the machine controller.

A fiber preparation machine for processing fiber material includes a store or filling chute for storing the fiber material before or after processing. A camera is directed into an interior of the store or filling chute, the camera having an optical axis oriented at an angle () with respect to a vertical axis that is perpendicular to a surface of the fiber material in a range of plus 30 degrees to minus 30 degrees. The camera has a resolution for detecting a particle having an extension of 0.1 mm2 on the surface of the fiber material.

A carder has a drum formed as a hollow cylinder having a drum wall, a longitudinal axis, a circumference, an outer surface, a length, and a clothing provided on the outer surface. Working elements are arranged relative to the outer surface of the drum. Stub axles or a continuous axle is formed along the longitudinal axis of the drum and connected to the drum wall by spokes or disks. One or more acceleration sensors that measures structure-borne sound are mounted on one or more of: a side of the drum wall facing the longitudinal axis, the stub axles, the continuous axle, the spoked, or the disks within the length of the drum.
