Abstract
A cradle stake (28) for being inserted transversely into a lane (20) between first and second rows (16) of tubes (14) in a tube bundle (10), for damping movement of the tubes in the bundle, includes first and second elongated metal strips (30, 32), which are arranged with their inner sides (40) facing one another, and a plurality of compression springs (42, 44 and 46) extending between the inner sides and being attached to the metal strips. In one embodiment, the springs have progressively greater lengths so that the metal strips are tapered, one to the other. In one embodiment, each elongated metal strip has a V-shaped bend along its length so that the metal strips themselves are also resilient, and each of the elongated metal strips includes indentation saddles (52) on outer sides thereof for engaging the tubes.
