<p>A feeder device (13) for a baler is operative to apply a sheet (8) to the cylindrical outer surface 12 of a cylindrical bale (7), so that the sheet (8) can form at least one covering layer on the outer surface (12) of the bale (7). The feeder device (13) comprises a feeder mouth (11) through which the sheet (8) can pass, a movable support (14, 15, 17) on which the feeder mouth (11) is mounted, means (13b) mounting the support (14, 15, 17) for movement between an inoperative withdrawn position in which the feeder mouth (11) is spaced from the outer surface (12) of the bale (7) and a feeding position in which the feeder mouth (11) is adjacent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), and at least one lip (16a, 16b) arranged in the feeder mouth (11) so as to guide the leading end (26) of the sheet into engagement with the outer surface (12) of the bale (7). The lip (16a, 16b) has a special shape, and a leading end (16A') of the lip is smaller than the width of the bale and/or the sheet and is extended to a base (16A") which is about the width of the bale and/or the sheet in order to curl up the edges of the sheet and to fold the edges of the sheet over the corners of the bale.
