摘要：
A feeder device (13) for covering the outer surface (12) of an agricultural bale (7) with a covering sheet (8), and which is intended primarily to be incorporated in a baler or a bale wrapper apparatus, and in which the bale is rotatable about its axis in order to pull the sheet (8) from a supply of sheet material (25) via the feeder device (13) and so that the sheet (8) can form at least one covering layer on the outer surface of the bale (7), the feeder device (13) comprising: A feeder mouth (11) through which the sheet (8) can pass as it is withdrawn from the supply (25) to cover the outer surface (12) of the bale (7)； A moveable support (14, 15, 17) on which the feeder mouth (11) is mounted； A means (13b) mounting the support (14, 15, 17) on the device (13) for movement between an inoperative withdrawn position in which the feeder mouth (1,1) is spaced from the outer surface (12) of the bale (7) and with a leading end (26) of the sheet projecting from the feeder mouth (11), and a feeding position in which the feeder mouth (11) is adjacent to the outer surface (12) of the bale (7) so that the leading end (26) of the sheet (8) can engage with the outer surface (12) of the bale 7； A pair of rollers (19, 20) mounted on the support (14, 15, 17) and located along the path of travel of the sheet (8) from the supply (25) to the feeder mouth (11), and so as to be engageable with opposed faces of the sheet (8) and thereby hold the leading end (26) of the sheet (8) when the support (14, 15, 17) is in its inoperative withdrawn position and as it moves to its feeding position, and in which the holding action of the rollers (19, 20) is capable of being overcome upon engagement of the sheet (8) with the outer surface (12) of the rotating bale (7) and consequent pulling force being exerted on the sheet (8)； and At least one flexible lip (16a, 16b) arranged in the feeder mouth (11) so as to be engageable deformably with the outer surface (12) of the bale (7) in order to guide th
