<p>The baler has an internal chamber (14) within which crop materials are coiled up into a cylindrical bale (56) by fore-and-aft spaced-apart, oppositely moving web stretches, the forwardmost stretch of which is looped around a forward drive roll (24). A special bale supporting roller (28) adjacent the bottom of the chamber keeps the bale (56) from riding against the web wrapped around the forward roll (24). The support roll (28) includes a cylindrical shaft and a plurality of resilient flaps extending tangentially outward from the periphery of the shaft. During baler operation, crop material tends to be carried downwardly by the forwardmost stretch into a zone located between the forward roll (24) and the support roller (28), but is immediately ejected from the zone by the roller flaps (64) and into the baling chamber, thereby preventing crop materials from wedging between the forward roll (24) and the support roller (28). When the flaps (64) are brought into contact with the bale, they yield to its weight, conforming to the periphery of the shaft, thereby forming a relatively smooth, circular roller surface for supporting the bale without tearing up the exterior thereof.</p> |
