PROBLEM TO BE SOLVED: To inexpensively prevent leakage of forage crops from a roll space by a simple structure.SOLUTION: The roll baler comprises: a half-split stationary housing and a movable housing a plurality of stationary-side rotary rollers supported by the stationary housing so as to form a semicircle opened to a cross-direction one side in width-direction view and a plurality of movable-side rotary rollers supported by the movable housing so as to form a semicircle opened to the cross-directional other side in the width-direction view, with the movable housing located at a closed position. The roll baler further includes a plurality of support bars that extend in the width direction, are adjoined with each other in the circumferential direction and located in a diametrically outward side of clearances between the rotary rollers, and a flexible sheet supported by the plurality of support bars so as to cover the diametrically outward side of the corresponding rotary rollers.COPYRIGHT: (C)2014,JPO&INPIT【課題】簡単な構造で且つ安価にロール空間から飼料作物が漏れ出ることを防止する。【解決手段】半割状の固定筐体及び可動筐体と、幅方向視において前後方向一方側に開く半円を形成するように前記固定筐体に支持された複数の固定側回転ローラと、前記可動筐体が閉塞位置に位置された状態の幅方向視において前後方向他方側に開く半円を形成するように前記可動筐体に支持された複数の可動側回転ローラとを有しているロールベーラ装置において、幅方向に延び且つ周方向に隣接する前記回転ローラ間の隙間の径方向外方側に位置する複数の支持バーと、対応する前記回転ローラの径方向外方側を覆うように前記複数の支持バーに支持された可撓性シートとを備える。【選択図】図5
