Abstract
Abstract A plurality of limbs or the like are secured together, to form a limb bundle (B). The limbs are positioned in a space defined laterally between a pair of posts (34, 38 or 80, 82) on one side (14) of a frame (12, 78) and a second pair of posts (36, 40 or 36', 40' or 86, 88) on the opposite side (16) of the frame (12, 78). A windlass (50, 52) is supported at the upper ends (46, 48) of the posts (34, 38 or 80, 82). A cable (60, 64) extends from the windlass (50) either downwardly and around the girth of the limb bundle (B), and then hooks on itself (62), to form a noose around the limb bundle (B), or it extends from the windlass (50) down to and around a pulley (68) then upwardly and over a mid portion of the limb bundle (B'), and then down to a dead end connection (66) at a lower portion of the frame (12). In either case, tightening of the cable (60, 64) imposes a squeezing force on the limb bundle (B, B').
