  • Patent number: 8323162
    Abstract: An inclined position of a product, leaving a nip between two folding rollers of a longitudinal folding machine, is corrected. The product is pressed into the nip between the rollers by a folding blade that can be moved up and down relative to a folding table. The product thus leaves the nip between the rollers and is transported in a direction of transport. The time of passage of a leading or a trailing edge of a product is detected at two measurement points which are spaced apart from each other and which are arranged transversely to the direction of transport of the product to be folded. Based on the times of passage that are detected by the two measurement points, and on commutation and/or data processing techniques, a deviation between a time offset detected during the passage of the corresponding product edge at the two measurement points, and a nominal time offset, is determined and analyzed.

  • Patent number: 5021039
    Abstract: An apparatus for manufacturing air-cushion dispatch packages, the apparatus comprising an unwinding mechanism for paper webs and air-cushion foil webs. The apparatus introduces air-cushion foil webs between the paper webs and seals each paper web to a foil web over a large area. Transverse and longitudinal sealers seal the edges of the packages. After each sealing operation, the webs are subsequently cooled. Pulling rollers press the paper webs in the edge regions of the packages and advance the webs. Cutters cut the dispatch packages to the desired format. Web controllers correct deviation of the paper webs. A cycle controller is included.

  • Patent number: 4994009
    Abstract: An improved easy open can end having a retained tear strip extending diametrically partly across the can end defined by a score line, and a graspable pull tab adjacent and outside the open end of the score line. The pull tab is attached to the can end by means of a rivet, the can end around the base of the rivet being deformed so as to slightly tilt the rivet toward the finger end of the pull tab. Accordingly, initial lifting of the pull tab is fully directed to the initial fracture of the score line immediately in front of the rivet, thereby ensuring desirable venting action of internal pressure and allowing opening of the can end with less effort.

  • Patent number: 4701155
    Abstract: A folder suitable for automatically folding successive sheets of paper, such as engineering drawings, by conveying them into a folder pocket to various distances depending upon where the fold is to be formed. To arrest the sheet at the proper position in the pocket, a photosensor senses when the leading edge of the sheet has reached a reference position in the pocket and, when the sheet has advanced further to the desired position, a solenoid-operated clamp is actuated to move transversely into the pocket and clamp the sheet momentarily in the desired position while the fold is being made. The amount by which the sheet advances beyond the reference position is controlled by producing an electrical pulse each time the sheet conveyor moves a predetermined amount, and counting these pulses to cause the clamp to be actuated when a count corresponding to the desired fold position has been accumulated.
