摘要:
A feeder for receiving a bale confined within a cylindrical body of the feeder comprises a cylindrical skirt and a plurality of bars upstanding from the skirt for confining animals outside of the feeder for accessing the bale within the feeder. The skirt is manufactured from a single integral sheet of metal which is bent about parallel horizontal lines to form coplanar skirt portions and flange portions and is then curved to form into the cylindrical shape. The upstanding bars are then simply welded to the skirt portions so that the structural strength for the feeder is provided by the cooperation between the curved and bent skirt sheet and by the vertical bars. The design reduces the materials required in the conventional hoop members and reduces the amount of labour required for manufacture while providing equal or increased strength.
