  • Patent number: 3964655
    Abstract: A pair of endless moving link chains have respective spans which are disposed in opposed relationship and driven in the same direction. One of the pair of the link chains carries thereon outwardly projecting blank holding pins at intervals along the length of the chain, while the other link chain carries thereon outwardly projecting sheet product pushing out pins. The spans of the link chains are disposed in converging relationship with respect to the moving direction of the spans. A blank comprising at least one sheet having cut lines defining a sheet product is supplied into the space between the spans at the upstream end of the space with respect to the moving direction. As the blank is conveyed between the spans the sheet product pushing out pins move transversely relative to and toward the blank holding pins because of the convergence of the spans and finally push out the sheet product from the remaining part of the blank which is being held by the blank holding pins.
