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.

A carding apparatus (2) and a carding method for producing a card web (12) are based on the carding apparatus (2) including a web forming device (5) for creating a preliminary web (3), followed by a web layering apparatus (7) which is followed by a card (6), and a controllable or adjustable profiling device (8). The profiling device (8) precedes or is associated with the web layering apparatus (7). The profiling device (8) is used for profiling the preliminary web (3) in order to preventively compensate for peripheral bulges in the card web (12) discharged by the card (6).

A support is provided for a flexible bend in a revolving flat card, the flat card having a cylinder and a cylinder axis. The support has at least three bearing points, with each bearing point comprising a bearing bolt and an adjusting lever. At each bearing point, the flexible bend is held on the bearing bolt such that a rotational motion of the bearing bolt brings about a displacement of the flexible bend radially with respect to the cylinder axis. Each bearing bolt has a bearing bolt axis, a fastening portion, a moving portion, and a contact surface for contact with the flexible bend. The contact surface is formed by a surface that spirals around the bearing bolt axis.

The invention relates to a support of a flexible bend (7) in a revolving flat card (1) comprising a cylinder (4) and a cylinder axis. The support comprises at least three bearing points (20), each of which has a bearing bolt (21) and an adjusting lever (26). The flexible bend (7) is held, at each bearing point (20), on the bearing bolt (21) in such a way that a rotational motion (22) of the bearing bolt (21) brings about a displacement of the flexible bend (7) radially with respect to the cylinder axis. The bearing bolt (21) has a bearing bolt axis (25), a fastening portion (23), a moving portion (22), and a contact surface (24) for the contact of the flexible bend (7). The contact surface (24) is formed by a surface, which spirals around the bearing bolt axis (25).
