Roll baler

#1. Field of the Invention

#The present invention relates to a roll baler including circumferentially rotatable conveyor elements limiting a compression space therebetween, and a device for wrapping up a roll bale, which is formed in the compression space, with a section of a sheath web, the wrapping-up device including pivotable start-up means for pressing the sheath web, at least in an initial phase of a wrapping-up process, against a surface of one of the rotatable conveyor elements and separation means for cutting the sheath web off after the wrapping-up process ends and pivotable between cutting and non-cutting positions.

#2. Description of the Prior Art

#The drawings show:

#FIG. 1 a side view of a roll baler with start-up and separation devices according to the present invention;

#FIG. 2 a front view of the roll baler shown in FIG. 1; and

#The roll baler, which is shown in the drawings, essentially includes a housing 1 having a compression space 2 which is defined by two conveyor band segments 3 and 4. Between the conveyor band sections 3, 4, there is provided an admission gap 5 through which a to-be-compressed material is admitted from a feed chamber 6 above the feed table 7. One of the conveyor band segments 3, 4, namely, the segment 3 is located in a stationary housing port 8 and is supported by deflection and/or drive rollers 9. The conveyor band segment 3 has a band section 10 which extends so far above the admission gap 5 that it forms a wall of the feed chamber 6. The second conveyor band segment 4 is located in a housing part 13 foldable about an upper pivot axle 11 into a bale discharge position.

#The housing 1 is limited, in the axial direction of the compression space 2, by two side walls 14 which are spaced from each other by a distance corresponding to the width of the compression space 2. The housing 1 is further limited by a rear wall 15 and by an upper cover 16.

#The housing 1 is further provided with a front wall 17. Above the admission gap 5, there is provided a wrapping-up device 18. The wrapping-up device essentially includes a supply roller 20, which is supported by support rollers 19, a start-up device 22, and a separation device 23. The supply roller 20 carries a sheath web 21, e.g., a net or foil. The start-up device 22 provides for take-off of the sheath web 21, and the separation device 23 cuts the sheath web 21 after a predetermined amount has been wound down.
