An apparatus for folding the top closures of tubular containers of square to rectangular cross section having a bottom into the form of a gabled roof. The top closure comprises first and second pairs of opposed quadrilateral panels, and each of the first panels has fold lines. The apparatus comprises first and second folding members provided at an intermediate portion of a path of transport of the container by a conveyor, between a filling device and a top closure sealing device along the path. The first folding member inwardly folds the first pair of panels between the second pair while the container is being transported by the conveyor, whereupon the second folding member operates to inwardly fold the second pair of panels over the first pair already folded by the first folding member. The top closure is foldable into the gabled form reliably and can therefore be subsequently sealed free of any trouble.
