Abstract
A method and machine for folding and finishing training pant diapers, whereby the diapers are formed from respective flat blanks, each of which is fed to a continuously-rotating, suction-type first wheel, and is folded into a U by clamping an intermediate portion of the blank on the first wheel by means of a folding member; retaining a trailing half of the blank on the first wheel, while detaching a leading half from the first wheel by means of a continuously-rotating, suction-type second wheel; transferring the leading half to a continuously-rotating, suction-type third wheel; and gradually superimposing the leading half of the blank onto the trailing half, as the trailing half advances on the first wheel, and after first removing the folding member from the blank.
