摘要： A round baler is disclosed as including an improved bale wrapping mechanism that provides positive feeding of the wrapper at the start of the wrapping cycle. The mechanism includes a shiftable frame carrying a pair of feed rollers, with one of the rollers being brought into engagement with a stretch of the belts moving toward the baling chamber when the frame is shifted to a starting position. The wrapping mechanism is configured so that the belt stretch and the one feed roller cooperatively define a nip that is located downstream along the wrapper path from the nip defined between the feed rollers. A cutting assembly is disposed to sever the wrapper at a point spaced downstream from the nip defined between the belt stretch and the one roller, thereby insuring the wrapper presents a free end that is trapped between the one roller and the belt stretch when the frame is moved to the starting position. The wrapper is consequently gripped between the belts and the one feed roller so as to be pulled from its supply.

摘要： The baler uses a single stuffer assembly to take crop materials from the center gathering augers of the windrow pickup and sweep such materials upwardly and rearwardly through a loading duct into the baling chamber via an opening in the bottom of the latter. A single set of side-by-side crop engaging forks of the stuffer assembly moves through a generally kidney shaped path of travel that includes extending the forks forward of the deposit zone, plunging the tips of the forks down to the deposit zone between the augers at a point forwardly of the mouth of the duct, sweeping rearwardly and upwardly thereafter through the remainder of the duct along the lower stretch path of fork travel, and the returning downwardly and forwardly along the upper stretch of the path of fork travel to the deposit zone. Such forks are able to extend forward of the deposit zone by positioning the augers, the deposit zone and the mouth of the duct back underneath the axis of rotation of the rotary drive of the forks.

摘要： The baler uses a single rotary feeder to take crop materials from the center-gathering augers of the windrow pickup and to sweep such materials upwardly and rearwardly through a loading duct into the baling chamber via an opening in the bottom of the latter. A single set of side-by-side crop-engaging forks of the feeder rotates through 360 degrees of travel in a complete cycle of revolution that includes movement up into the bale chamber for presenting the crop materials to the plunger as the latter moves rearwardly in its compaction stroke. Such forks pass through clearance slots in the plunger as the latter wipes crop materials off the forks, but then the forks dip down quickly and temporarily out of the bale chamber into clearance positions as a trailing transverse knife on the plunger comes across the inlet opening of the chamber to sever any dangling strands of crop materials. The forks then pop back up into the bale chamber behind the rearwardly moving plunger until sweeping on down around and into the proximity of the center-gathering augers as their cycle of revolution is completed.
摘要翻译：打捆机使用单个旋转进料器从地层拾取器的中心收集螺旋钻采集作物材料，并且通过后者的底部中的开口将这种材料向上和向后扫过装载管道进入打包室。供料器的一组并排作物接合叉在完整的旋转循环中旋转360度行程，其包括向上进入捆包室的运动，用于当料斗材料向后移动时将作物材料提供到柱塞其压实冲程。这样的叉子通过柱塞中的间隙，因为后者将作物材料从叉子上擦拭，然后叉子快速地临时从捆包室中伸出到间隙位置，因为柱塞上的后横向刀穿过入口开口该房间切断任何悬挂的作物材料。然后，叉子弹回到向后移动的柱塞后面的捆包室中，直到它们的旋转周期完成为止，绕过中心收集螺旋钻的周围。
