6 and Japanese Utility Model Application No. 166635', 1983, etc., but in both cases, the veil chamber was in the form of a single chamber. For this reason, after the grass was rolled in a single room, it was necessary to stop the supply of grass to the bale room while tying the grass with a string and discharging it from the bale room in the same room.

Means for Solving the Problem This invention provides a bale chamber (2) for rolling the grass (1) to be picked up, and a system for feeding the rolled grass (3) rolled up in the bale chamber (2). The roll baler has a structure in which a packing chamber (5) is provided, and a string (4) is hung on the outer circumferential surface of the packing chamber (5) to be tied.

Functions and Effects of the Invention When the picked-up grass (1) is sent to the bale chamber (2), the bale chamber (2) rolls the grass (1) and rolls it into a roll-shaped grass (3). When the grass is fed into the packing room (5), the packing room (5) receives the grass and ties it up with a string (4) around the outer circumferential surface of the roll-shaped grass (3), knots it, and then discharges it.

The bale chamber (2) receives and rolls the grass (1) that is continuously picked up, since the string (4) of the rolled grass (3) may depend on the packing chamber (5) for knots. Since it can be rolled up, efficient continuous work is possible.
