摘要:
A method for controlling a brake device (60) of a wrapping material dispensing system (30), further comprising wrapping material roll (31) with wrapping material (41), of a baler (1) whereby the brake device (60) is controlled according to a braking force profile (80, 80', 80") with different levels of braking force in function of the discrete wrapping phases. According to the invention the braking force profile (80, 80', 80") is a function of at least one wrapping material characteristic that is the type of wrapping material (41).
摘要:
An agricultural baler (10)comprises a chamber (14) for forming therein cylindrical bales of crop material and a pick-up (12) for picking up crop material from a field and feeding it to said bale forming chamber (14). A dispensing mechanism (20) is provided for dispensing sheet-like wrapping material, e.g., stretch film, from a roll (32) to said chamber (14) and comprises components (34-40, 48) that have surfaces that contact said wrapping material during the wrapping process. Each of said contact surfaces has low wettability characteristics to thereby reduce the risk of said wrapping material adhering to said surfaces.
摘要:
An agricultural round baler (1) comprises a mechanism (30) for placing netwrap (41) over the edge of a cylindrical bale that is created in the baling chamber (24a). The mechanism includes a netwrap delivery assembly (50) having of a pair of arms (51) pivotally affixed to the outside of the baling chamber sidewalls (24). The arms hold an assembly frame (54). An actuator (70) controls the pivoting motion of the delivery assembly (50) inserting the netwrap between the stationary dimple roll (8) and the pivot roll (9) of the sledge assembly (26). Positioned outside the sidewall (24) and inside an outer frame member (25) is a transition area (90). The netwrap (41) is inserted between the stationary dimple roll (8) and the pivot roll (9) as well as into the transition area (90). Because the width of the delivery assembly (50) is wider than that of the cylindrical bale, a portion of the netwrap (41) is inserted over the edge of the bale by use of the transition area (90).
