  • Patent number: 6050057
    Abstract: Packing apparatus for packing mail items, magazines, books, CDs and like products composed of one or more layers, comprising a product-assembling path, a folding station, and a separating station, the folding station comprising a first conveyor belt on which at least a part of the packing material web is located which extends below the products to be packed, a pulling element which is arranged above the first conveyor belt and engages parts of the packing material web located at the top side of the products to be packed, and connecting means by means of which the longitudinal edges of the packing material web are interconnected, a pressure plate which is arranged above the first conveyor belt, the top side of which pressure plate is engaged by the pulling element, in operation, with the interposition of at least the longitudinal edges of the packing material web, the distance between the first conveyor belt and the bottom side of the pressure plate being such that products of different thicknesses can pass th

  • Patent number: 5706632
    Abstract: A method for obtaining an output stream of mutually different graphic products in a desired order, for instance sorted according to address code, wherein the products are assembled in an assembly line as desired by an addressee and/or a sender, and after the assembly line the product undergoes at least one additional operation, depending upon the desire of the addressee and/or sender, for which purpose the product stream is divided over at least two sublines in which the or each additional operation, such as for instance packaging, is carried out, whereafter the products are merged again in a single downstream line, characterized in that, for the purpose of avoiding buffers, the order of the products (2) that are formed in the assembly line (3) is such that, allowing for the desired additional operations in the sublines (9, 10), the products, after traversing the sublines, have acquired the desired order in the downstream line (14, 15), while the products in the sublines (9, 10) can be temporarily delayed and

  • Patent number: 5653094
    Abstract: A method and apparatus for the mutual repositioning of products (4), which products are fed at a specific speed and with a specific distance in between, and the mutual position of the products (4) being changed by means of speed influencing means (2, 3), while for the mutual repositioning of products (4) consisting of several layers, for adjusting the mutual position of graphic products in a packing apparatus, a speed influencing means (2, 3) is brought into engagement with the product both at the top side and at the bottom side of the product (4), which two speed influencing means (2, 3) are always driven at the same speed relative to each other.

  • Patent number: 5647192
    Abstract: Folding element (1) suitable for use in a packaging apparatus in which in operation a strip of packaging material (7) to be fed continuously is guided from a feeding direction over the folding element (1) and, while a shell is formed from the material strip, is guided further from the folding element in a product conveying direction, with the feeding direction and the product conveying direction including an angle. The folding element (1) comprises a front face (12) extending in the feeding direction and a top face (17) extending in the product conveying direction, over which front and top faces (12, 17) the material strip (7) moves in operation, the front face (12) being bounded on opposite sides by a fold forming edge (13) which intersects the intersecting line of the front and top faces (12, 17) in a folding point, in which folding point in operation folds are formed in the material strip (7). A packaging apparatus comprising such folding element (1).
