Abstract
A main cylinder casing segment for use with a revolving flat on a card, each of the segments including opposite end portions, adapted for fastening on a frame of the card, and a longitudinal body between the end portions for covering the main cylinder. The body includes two plate-shaped parts, a first of the parts has a surface adapted to be inwardly directed toward a working area of the card, during operation of the card, and a second of the parts constituting a stiffener for the segment. Further, the first part of the second part are connected for transferring bending stresses between the parts. The segment is thus formed as a hollow body, preferably extruded.
