Abstract: In the case of a method of folding stacks of sheets, which can consist of one or of a plurality of sheets that may have different folding resistances, by supplying a plurality of stacks of sheets to a folding device by means of a temporally successive, cyclic supply which comprises phases of movement and pauses in movement, a stack folding resistance for a respective stack of sheets is first determined on the basis of at least the number and/or the folding resistance of the individual sheets forming a stack of sheets. Following this, the respective stack of sheets is folded, the folding speed used by the folding device for folding said stack of sheets being controlled in dependence upon the stack folding resistance that has been determined for this stack of sheets, the control of the folding speed of the folding device being carried out during respective pauses in movement of the cyclic supply.
Abstract: A machine for and a method of manufacturing folded containers, especially folded blanks. The machine has a mechanism for applying adhesive, a folding station, and a pressure-application station with pressure-application mechanisms for forcing the adhesive-coated seams together to seal them. The invention ensures that, when the machine is stopped, all the blanks to which adhesive has been applied but which have not yet been folded to form sealed seams are automatically marked or rejected. The machine has both a marking or rejecting mechanism downstream of the pressure-application station and computerized controls that, when the machine is stopped, determine the number of folded blanks in the production line between the adhesive-application mechanism and a first pressure-application mechanism in the pressure-application station and, once the machine is started again, control the marking or rejecting mechanism.
Abstract: A dunnage converter mechanism for producing relatively low density pad-like cushioning dunnage product from flexible sheet-like stock material in roll form. The converter includes means for pulling the sheet-like stock material from a supply roll thereof into the mechanism while causing inward rolling of the lateral edges of the sheet-like stock material, resulting in a pad-like cushioning product emitted from the machine, with the product having lateral relatively resilient pillow-like portions and a central connecting section holding the pillow-like portions together in generally side-by-side attached relation.
Abstract: Method for fixing a handle to a package. The closing flap of a package is provided with the ears is attached, which strip rises to form a handle when the foldable ears bearing the strip are folded towards the strip.
