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.

A carder includes a machine frame, a controller, and a drum provided with a clothing on an outer surface thereof. Working elements are disposed relative to the outer surface of the drum. The drum includes two stub axles or a continuous axial along a longitudinal axis thereof, the continuous axle having a first end and an opposite second end and each of the stub axles having an outer end face. An acceleration sensor that measures structure-borne sound is mounted on the end face of at least one of the stub axles or on the first end of the continuous axle.
