A flap folding unit, comprising at least one flap folding device having a disc-like member being configured to be arranged in a first position to urge passing front flaps of an associated cardboard case to fold, and in a second position to allow unfolded rear flaps of the associated cardboard case to pass the disc-like member, the disc-like member comprising a convex portion and a recessed portion, the disc-like member being connected to a link arm, and the link arm extending substantially parallel with a cardboard case feeder, the convex portion being located at one portion of an outer periphery of the disc-like member and the recessed portion being located at a different portion of the outer periphery of the disc-like member.
A flap folding unit for interacting with unfolded front and rear flaps projecting from a cardboard case as the cardboard case moves along a transport path, the flap folding unit comprising:
- a link arm positioned along the transport path and a rotatable disc-shaped member having an outer periphery, a first portion of the outer periphery of the disc-shaped member being a convex portion and a second portion of the outer periphery of the disc-shaped member being a recessed portion, the recessed portion and the convex portion being circumferentially spaced from one another, the disc-shaped member being connected to the link arm and being rotatable relative to the link arm to rotate:
- i) from a first position in which the convex portion of the disc-shaped member contacts the unfolded front flap of the cardboard case while the cardboard case is being moved along the transport path to urge the front flap to fold;
- and ii) to a second position in which the recessed portion allows the unfolded rear flap of the cardboard case to pass by the disc-like member.
