A method is provided for supplying a corrugated board article or a paperboard sheet article from a feeder apparatus for receipt by an article processing host machine. The method includes feeding the article to a feeder apparatus including a sheet supporting feed table surface having a feed end and a delivery end, feed elements, and a control surface selectively movable between a covering state and an exposing state. In the exposing state the feed elements are exposed to contact and drive the article along the sheet supporting feed table. The control surface is selectively movable to an angled state to selectively angle the control surface to consecutively conceal the respective feed elements as the article moves over the feed elements.

It is generally a goal to reduce the height dimension of a case-making device. A case-making device 90 comprises a box-sheet-holding part 10 and an extraction part 20. The box-sheet-holding part 10 holds a plurality of box sheets S to be processed into container boxes B such that the box sheets S extend in an upright direction UR. The extraction part 20 extracts one box sheet S from the box-sheet-holding part 10. An upright-direction UR dimension of the box sheet S is a first dimension H1. The extraction part 20 moves the box sheet S in the upright direction UR by a second dimension H2 shorter than the first dimension H1.

A machine for assembling boxes comprising five independent parts including two head walls, two side walls and a base with peripheral flanges that engage with grooves in a lower portion of the side walls and the head walls. Ends of the head walls have end tongues that are inserted into notches adjacent to ends of the side walls. The machine includes a central assembly station comprising a base ring inside which a stationary forming die is disposed. A base of a box to be formed is positioned on a lower face of the stationary forming die such that while the base of the box is held in position, horizontal push devices are activated which move the head walls and the side walls towards the base of the box which is locked in position against the lower face of the stationary forming die.

A machine for manufacturing disposable cups, including a side element, obtained from a blank of sheet material folded into a conical shape and sealed by a bottom element of circular shape, including a forming wheel rotatable with continuous motion. The forming wheel has a plurality of peripherally distributed forming assemblies including respectively a mandrel of tubular form carried by a support member swinging around an axis parallel to said axis of rotation of the forming wheel. First feeding means is adapted to orderly collect and insert single bottom elements into corresponding forming assemblies of the forming wheel. Second feeding means is adapted to collect single blanks in an orderly manner from a store in which the blanks are stacked and to transfer them in sequence, in an extended configuration, to the corresponding forming assemblies of said forming wheel.

Provided in a paper sheet feeding apparatus and a box making machine are: a plurality of wheels capable of supplying a sheet by coming into contact with a lower surface of the sheet; a grate liftable and lowerable to an ascending position positioned above upper edges of the plurality of wheels and a descending position positioned below the upper edges of the plurality of wheels; a drive motor; an elevating device capable of lifting the grate to the ascending position by rotating the drive motor in one direction and capable of lowering the grate to the descending position by rotating the drive motor in the other direction; and a control device capable of adjusting an amount by which the grate is lifted and lowered by the elevating device by controlling the drive motor.
