  • Patent number: 6106452
    Abstract: A machine and method for making cushioning dunnage products by crumpling paper as well as the produced dunnage product is disclosed. The dunnage product is produced from multi-ply paper-like material in which the lateral edges are folded back, and the material is then driven, crumpled, and connected by successive compressions. The folding, crumpling and connecting operations are formed independent of each other in successive steps. By separating the steps, perforations or tearing is avoided, thereby permitting the use of less expensive raw materials, such as recycled paper, rather than the more expensive high quality kraft paper.

  • Patent number: 5891008
    Abstract: An improved method is disclosed for forming a strata of overlapping sheets suitable for use in a pop-up dispensing system. The sheets are cut from ribbons which initially have edges essentially parallel to the longitudinal axis of the ribbon. At least one side edge of each ribbon is stretched to form a knee-like protrusion, with the opposing side edge being either, substantially parallel to the longitudinal axis of the ribbon, or also stretched to form one or more knee-like protrusions on the opposing edge. The ribbons are then aligned so that a knee-like protrusion on one edge aligns with either the essentially parallel edge of an adjacent ribbon or a knee-like protrusion on the side edge of an adjacent ribbon. After phasing, the ribbons are overlapped creating a series of predetermined areas of greatest overlap adjoining areas of least or no overlap, such that successive ribbons are bonded only by the interfacial interaction between each ribbon.

  • Patent number: 5876317
    Abstract: A method and apparatus are provided for preparing discrete blanks from a wound strip comprising a plurality of connected blanks. Each blank has a determined separation point and a marker at a determined distance from the determined separation point for making soft-type wrappers. First, the wound strip is unwound under tension. Next, at least a section of a particular blank of the unwound strip is cut and any other milling and preparatory steps are performed by appropriate rollers and mechanisms. The tension of the unwound strip is slackened periodically, e.g., via chocking these rollers, and the unwound strip is realigned relative to the marker of the particular blank during this slackening, e.g, by identifying the marker via a sensor and driving the strip via rollers. The particular blank of the realigned strip is separated at the determined separation point of the particular blank to separate the particular blank from the realigned strip.

  • Patent number: 5871430
    Abstract: A machine for producing containers comprises processing stations with components adaptable to the shape and size of the material sections used for the container. In the case of a change in form, in particular a change in the format of the sections of material to be used, it is necessary to change the relevant adaptable components. Instead of the conventional approach where the new components must be fine-tuned after an exchange has taken place, fitting surfaces are provided at the processing stations, against which a section of the adaptable components can always be placed in the same position. Therefore, time-consuming installation of exchangeable machine components is avoided.
