  • Patent number: 10240261
    Abstract: 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.
