摘要

Flexible ruler device (10) comprises two profile strips (12.1, 12.2) that are elastically flexible in a transverse direction (E). Between the strips are arranged a number of tensioning blocks (15) at a regular preset separation distance. Each tensioning block is fixed at one of its ends to the first profile strip (12.1), while the other end is detachably held in the second profile strip, when a desired curved shape is obtained.
