  • Patent number: 7765921
    Abstract: A press cage bar for a device for expressing liquids, which is bounded by at least one pressing edge in the area of a wear surface of a hard layer and which, in the area of at least one lateral face of the body of the cage bar, has at least one spacer that is raised above the lateral face. The spacer is formed as a deposit weld on the lateral face of the cage bar and is provided with a certain bottom clearance from the underside of the cage bar, which is on the opposite side of the cage bar from the wear surface. The spacer extends along the lateral face no farther than to the hard layer. The extent of the spacer transversely to a longitudinal axis of the lateral face is greater than its extent in the direction of the longitudinal axis of the lateral face. The spacer has increasing thickness perpendicular to the lateral face in a direction extending from the hard layer towards the underside of the cage bar.

  • Publication number: 20070062858
    Abstract: Disclosed is a cage bar for a liquid pressing device, which is delimited by at least one pressing edge in the area of a wearing surface of a hard layer. Said cage bar comprises a spacer that is located in the region of at least one lateral face of a basic member and rises above said lateral face. The spacer (15) is welded onto the lateral face of the cage bar (8), is located at a basic distance (20) from a base (17) of the cage bar (8), which faces away from the wearing surface (11), and extends along the lateral face, no further than to the hard layer (14). The spacer (15) also extends perpendicular to a longitudinal axis of the lateral face, said extension being greater than the extension thereof in the direction of the longitudinal axis of the lateral face (21). The spacer (15) has an increasing thickness (22) perpendicular to the lateral face in a direction extending from the hard layer (14) to the base (17).
