Abstract: Apparatus for making tapered four-sided sheet metal containers comprises a tapered four-sided mould 42 and a folding mechanism 26.1 for folding a sheet metal blank onto the mould. The folding mechanism comprises a carrier 28 and four folding elements 30, 32 pivotally mounted on the carrier. When the mould and the folding mechanism is displaced towards one another with the sheet metal blank 10 disposed between them, the folding elements pivot about their pivotal mountings and fold peripheral portions of the blank onto the sides of the mould.

Abstract: A bin for transporting and storing agricultural produce and industrial products. The bin comprises a metal base frame, four metal posts, and a metal top frame. The top frame is constituted by components forming downwardly open channels which receive the upper ends of vertical slats. The top frame can be taken apart to release the top ends of the slats. The frame can have inwardly directed teeth onto which the slats are impaled, or the slats can have slots or holes into which the teeth fit. Crossed straps join the posts to prevent outward bulging of the slats when the bin is filled. The floor can also be constituted by slats.
