ABSTRACT OF THE DISCLOSURE APPARATUS FOR CREASING FOLD LINES IN A SHEET OF CARDBOARD Apparatus for creasing fold-lines in a sheet of cardboard, especially for a lid e.g. for a tin plate stack, has an upright support surface for the cardboard sheet and a conveyor for bringing the sheet in an upright position against the support surface. Adjacent the support surface is a resilient track, and a pressing wheel having a tapered periphery forming a creasing edge is arranged to move along said track so as to form a creased fold line in a front side of the sheet when the sheet is interposed between the wheel and the track. A suction pad engages and picks up the sheet on the support surface and is movable horizontally and vertically so as to bring the sheet into the desired position for creasing on the said track and is rotatable so as to rotate the sheet in its plane in order that fold lines at angles to each other can be creased in the sheet. Creasing tongs are arranged to engage the rear side of the sheet to form creases therein.
