ABSTRACT:
Apparatus and process is provided in which a blast of air is impinged on a fruit-bearing limb grouping to cause it to bend, preferably downwardly, and thereafter cause a second blast of air to impinge on the bent-limb grouping in the opposite direction. Advantageously, the two blasts of air move in unison laterally along and around the tree with the first blast being ahead of the second blast and with the spacing between the two blasts being correlated with the rate of transverse movement so that, as soon as the first blast of air passes the limb grouping which is bent down, the second blast of air impinges on said grouping from beneath, in a manner to reinforce the natural rebound of the limb, whereby the normal whiplash effect which takes place on the rebound of the limb grouping is enhanced. In one form of the invention, the means for directing the blasts is stationary except for the transverse movement. In another form, it is adapted to rotate about a common center as a rotating unit, which in turn is adapted to rotate about a second common center which is fixed except for said transverse movement.
