ABSTRACT:
A flexible rake has a set of flexible tines extending forwardly from a supporting panel and means for retaining the tines in the form of a pair of retaining strips one of which contains on one side thereof a number of spaced inverted cups and the other of which contains on one side thereof a number of spaced nipples. The spacing between the nipples is somewhat different from the spacing between the cups. One of the strips is placed above the tines and the other of the strips is placed below the tines so that the nipples can extend between the tines and into corresponding cups, and they are fastened together. Each tine is thus individually held between a spaced-apart pair of nipples and cups, and is allowed freedom of movement both laterally and vertically relative to the retaining strips. The retaining strips are also allowed some movement in a fore and aft direction and in a twisting direction, relative to the tines. The retaining strips have a convex arc and also a crown so that the center part of the rake tines is at a higher elevation than the side parts.
