Abstract
A device for use on palletized loads of containers for maintaining tension in vertical strapping comprises a rectangle (20) having outer dimensions commensurate with the dimensions of a pallet or dolly on which. containers are to be stacked in layers, each side of the rectangle comprising upper and lower leaves (21L, 22L) diverging from hinge means at the inner edge of the side, the lower leaves (22L) of all four sides being disposed in a common plane, and spring means (23) urging the outer edges of the upper and lower leaves apart. In one form of the device (20) the sides of a pair of rectangular frames (21, 22) constitute the upper and lower leaves (21L, 22L) and conical coil compression springs (23) are provided between the frames to urge them apart, tethering means (25, 27) adjacent the inner edges of the frames being such as to form the hinge means between the leaves, while tethering means (24, 26) adjacent the outer edges of the frames limit the extent to which the leaves (21L, 22L) are caused to diverge. In other forms the spring means is integral with the hinge means.
