Abstract:
1. 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 two spacers that are raised above the lateral face, wherein the body has a substantially rectangular cross section having an upper surface formed by the wear surface, the wear surface being angled and inclined such that pressing edge of the cage bar projects above a wear surface of a preceding cage in a direction of rotation, wherein each spacer ( 15 ) is formed as a deposit weld on the lateral face ( 21 ) of the cage bar ( 8 ); that each spacer ( 15 ) is provided with a certain bottom clearance ( 20 ) from the underside ( 17 ) of the cage bar ( 8 ), which is on the opposite side of the cage bar from the wear surface ( 11 ); that each spacer ( 15 ) extends along the lateral face ( 21 ) no farther than to the hard layer ( 14 ); that the extent of each spacer ( 15 ) transversely to a longitudinal axis ( 9 ) of the lateral face ( 21 ) is greater than its extent in the direction of the longitudinal axis ( 9 ) of the lateral face ( 21 ); and that each spacer ( 15 ) has increasing thickness ( 22 ) perpendicular to the lateral face ( 21 ) in a direction extending from the hard layer ( 14 ) towards the underside ( 17 ) of the cage bar ( 8 ), wherein the surface of each spacer ( 15 ) that faces away from the lateral face ( 21 ) is ground, wherein each spacer is shaped so that the spacing region between neighboring cage bars extends and increases from the hard layer in the direction of the underside, the spacers being spaced from one another along the lateral face ( 21 ).
