Abstract
Abstract A roll forming crop baling machine (10) which forms the bale (42) by the use of rigid rollers (24, 26, 28, 30, 32, 34, 36, 38, 48, 50, 52, 54, 56, 58) and which nevertheless produces bales with a more even bale density. One set of stationary rollers (24, 48, 50, 52, 54, 56 and 58) and another set of shifting rollers (26, 28, 30, 32, 34, 36, 38) are used to form and compress the bale during a major portion of its growth. Each shifting roller gradually moves outward from an initial position near the core (40) of the forming bale which is radially inward from the stationary rollers, to a final position forming a continuous outer boundary with the stationary rollers

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
124 words
1 . A baler for forming cylindrical bales comprising multiple rotating rollers generally enclosing a bale forming region and operable to impart motion to baleable material as it is fed into the bale forming region to form a bale of cylindrical shape, characterized by means (86, 94, 95) permitting shifting of at least a portion of the rollers (26, 28, 30, 32, 34, 36, 38) from a closely grouped position at the beginning of the formation of the bale (40) to a position of expanded grouping as the final size of the bale (42) is reached; and means (90) for restraining the shifting rollers (26, 28, 30, 32, 34, 36, 38) in their expansion paths to create compressive force on the bale so formed.
Claim 2
Dependent Claim
124 words
1 . A baler for forming cylindrical bales comprising multiple rotating rollers generally enclosing a bale forming region and operable to impart motion to baleable material as it is fed into the bale forming region to form a bale of cylindrical shape, characterized by means (86, 94, 95) permitting shifting of at least a portion of the rollers (26, 28, 30, 32, 34, 36, 38) from a closely grouped position at the beginning of the formation of the bale (40) to a position of expanded grouping as the final size of the bale (42) is reached; and means (90) for restraining the shifting rollers (26, 28, 30, 32, 34, 36, 38) in their expansion paths to create compressive force on the bale so formed.
Claim 3
Dependent Claim
60 words
A baler according to claim 1, characterized in that it comprises a set of rollers (24, 48, 50, 52, 54, 56, 58) which are stationary in position at the prescribed outer limits of the bale size, and a further set of shifting rollers (26, 28, 30, 32, 34, 36, 38) positionable inwardly of the stationary rollers and movable outwardly therefrom.
Claim 4
Dependent Claim
41 words
A baler according to claim 1 or 2, characterized by the path of a shifting roller (26, 28, 30, 32, 34, 36, 38) being part of a circular orbit around an adjacent stationary roller (24, 48, 50, 52, 54, 56, 58).
Claim 5
Dependent Claim
42 words
A baler according to any of the preceding claims characterized by each shifting roller (26, 28, 30, 32, 34, 36, 38) being powered by a chain drive (84, 86, 88) from the adjacent stationary roller (24, 48, 50, 52, 54, 56, 58).
Claim 6
Dependent Claim
61 words
A baler according to any of the preceding claims characterized by the final expanded grouping position of a shifting roller (26, 28, 30, 32, 34, 36, 38) being such that it acts in cooperation with the adjacent stationary roller or rollers (24, 48, 50, 52, 54, 56, 58) to rotate and compress the bale (42) in its final size and position.
Claim 7
Dependent Claim
24 words
L. A baler according to any of the preceding claims characterized by the restraining means of the shifting rollers being formed by springs (90).
Claim 8
Dependent Claim
38 words
A baler according to any of the preceding claims characterized by the shifting motion of the shifting rollers (2o, 28, 30, 32, 34, 3D, 38) being caused by the force resulting from the expansion of the forming bale.
Claim 9
Dependent Claim
57 words
A baler according to any of the preceding claims characterized by bale ejection means for unloading the final size bale from the baler (10); the bale ejection means comprising means (26, 36, 38) for moving the bale rearward on the baler frame (12) to a location where the bale weight is unsupported and falls from the frame.
Claim 10
Dependent Claim
39 words
A baler according to claim 8, characterized by the baler comprising a clamshell tailgate (60) and means (102) to raise the tailgate to a height which permits unrestrained movement of the final size bale rearward on the frame (12).
Claim 11
Dependent Claim
29 words
A baler according to claim 8, characterized by the bale ejection means being formed by the frontmost shifting rollers (26, 36, 38) and the restraining means (90) acting thereon.
