  • Patent number: 5211620
    Abstract: A cushioning conversion machine for converting a sheet-like stock material, which may be viewed as having two edge sections and a central section, into a cushioning product is provided. The machine includes a conversion assembly for converting the sheet-like stock material into a cushioning product and a supply assembly which supplies the sheet-like stock material to the conversion assembly. The stock material is supplied to the conversion assembly in such a manner that its edge sections must travel in a longer path than the central section thereby creating edge-tension in the edge sections of the stock material. While a certain minimum conversion-tension is necessary in the edge sections of the stock material to properly convert the stock material into a cushioning product, a certain continuous tearing-tension, greater than the minimum conversion-tension, will cause a continuous tear in the stock material.

  • Patent number: 5088972
    Abstract: This invention comprises apparatus and methods for folding and crimping shredded strips of sheet material into preselected lengths of interlocking, decorative material and/or bulk packaging material. The apparatus generally includes an attachment for a commercial paper shredding device which shreds sheet material therein. The apparatus comprises a movable barrier against which the shredded strips of sheet material are impelled upon being expelled from cutting blades of the shredding device. The movable barrier causes the strips to become controllably jammed within a confined area between the barrier and the cutting blades. Further insertion of additional strips into the confined area causes the strips to become compacted, folded, and crimped against a remaining dam of jammed sheet material located within the confined area. This causes the strips to fold and press against themselves, and form lengths of thin sheet material having an accordion-shaped configuration.

  • Patent number: 5056293
    Abstract: An annular container mounted at the base of a passage between a layering tube and a central mandrel is charged with a layered tube of flexible tubing delivered over a floating mandrel when coaxially in contact with mandrel by driving rollers coacting with pinch rollers on the floating mandrel. The tubing passes over the mandrel and gathers in the layering tube while being compacted by two sets of shoes reciprocated 180.degree. out of phase by rotating discs and connecting rods. When sufficient tubing has been delivered the floating mandrel is raised to enable a hot wire to pass between the mandrels to sever the tubing. The layering tube and central mandrel with the container can then be carried by a turntable through further stationary positions where the layered tubing is further compressed by reciprocable rings, a lid is put on the container to form a cassette and the cassette is discharged.

  • Patent number: 4718883
    Abstract: A process for manufacturing articles of filter paper in which the wet strength of the regions of weak points resulting from mechanical working is increased by the application of a wet strengthener of cross-linked cationic polyalkylenimines. For this purpose, the wet strengthener is applied only to the regions of the weak points after the filter paper has been manufactured. Seams or edge reinforcements are formed by relief printing before the application of the wet strengthener and a heat treatment takes place after application of the thermoplastic wet strengthener to cause the wet strengthener to harden. The application of the wet strengthener is effected in measured doses so that the legally prescribed maximum amounts to be added are not exceeded.
