Abstract

In order to configure the bending of a plate in an intermediate space between two blade rings, arranged along an axis of a compressor and having blades extending along a radius in a simpler and more effective manner, the novel concept provides a bending device which can be positioned in the intermediate space and has, according to the invention, a fixing element for the bending device, a hydraulic system and a punch which can be actuated by the hydraulic system. Accordingly, a method for bending a plate in the intermediate space provides for a bending device to be positioned in the intermediate space, for the bending device to be fixed in the intermediate space, and for a punch of the bending device to be hydraulically actuated for bending the plate, the punch being moved toward the plate to be bent, and the plate being bent under the effect of the punch.
