Abstract: The invention relates to a box-like container for flat mailings in the upright position, comprising a stack support, which may be removed from the container open at the top, a base, two narrow front face walls and two lateral longitudinal walls. The mailings are arranged with the largest sides thereof facing the front face walls. The inner sides of the lateral longitudinal walls comprise straight long recesses, open to above, arranged at regular intervals perpendicular to the base, which are wider in the longitudinal direction of the lateral longitudinal walls than the slot like openings thereof to the container interior. The stack supports have formed elements at both lateral ends thereof which may only be slid into place in the long recesses perpendicular to the base with a positive fit connection through the slot like opening.

Abstract: The present invention relates to an apparatus for stacking articles. The articles may comprise mail pieces. The apparatus comprises a base having a top surface. The top surface defines a rake element having extending fingers defining open spaces therebetween. A receiving unit is mounted proximate to the rake. The unit may be made to rotate. The unit further comprises a plurality of coils. The coils may be helical, concentric and vertically displaced so as to define a vertical open space therebetween. When rotating, the coils may be made to move in the direction of a support positioned atop the top surface. The support may further comprise a spring bias to urge the support against a stack of articles. A supporting wall is also provided as well as a supply element which directs incoming articles into the vertical opening. The movement of the coils transports the articles to a stack which is support on one side by the support, on another by the supporting wall and on yet another by the top surface.

Abstract: The invention concerns a process and a device for unloading a mail piece container, open at the top, with sidewalls that slant toward the outside, that is loaded with mail pieces that stand upright next to one another. According to the invention, the mail piece stack, after having been compressed, is held by holding supports that are inserted into the container and that feature driven revolving conveyor bands. While the supports are being inserted, the conveyor bands are driven in such a way that the conveyor band segments in contact with the mail piece stack are motionless with respect to the mail pieces. Next, the container is tilted by >90° along with the mail pieces and the holding supports. After the container is tilted back somewhat, a base plate is inserted and the whole ensemble is tilted back to the point where the stack stands on the horizontally positioned base plate. Then the container is removed towards the bottom.

Abstract: The stack of flat mail pieces that are arranged adjacent to one another on a support can be portioned with the aid of at least one displaceable holding support containing a conveyor belt because the support is divided into a horizontally oriented, stationary section and an adjacent section that can be pivoted about a pivoting axis positioned at the end of the pivotable section in the stacking direction. During the portioning process, the pivotable section extending downward at an angle from the stationary section is pivoted downward into a horizontal position. A holding support with a conveyor belt that is driven downward during the pivoting process is arranged underneath the stationary section at its border with the pivotable section. An additional support is arranged on the frame of the pivotable section of the support above the mail pieces. This additional support holds the stack remaining on the stationary section of the support.

Abstract: In the device for emptying of rectangular open-top mail piece containers (1) featuring lateral guiding elements (2), the mail piece containers (1) are guided and shifted on lateral guiding tracks (3). The bottom of the mail piece container (1) features continuous recesses (11) that extend in the shifting direction. Between the guiding tracks (3) freely protruding supporting fingers (6) are provisioned that are oriented in a direction toward the shifting direction. The recesses (11) in the container bottom and the supporting fingers (6) are dimensioned and positioned in such a way that the supporting fingers (6) move into the recesses (11) underneath the mail pieces, when the mail piece container (1) is shifted in its position. The—in the shifting direction—forward and rearward side walls of the mail piece container (1) feature, at least above the supporting fingers (6), cuts (5) that are open at the top.

Abstract: In a process for improving the adhesive strength of radiation-cured films of acrylate resins which comprise compounds having at least one amine group and at least one unsaturated acrylate group and, in particular, an amino-modified acrylate resin having a molecular weight Mn of at least 300, on substrates, the acrylate resins are admixed with amine-hardenable polyepoxides having an epoxide value of from 1 to 15 mol/kg such as polyglycidyl esters or polyglycidyl ethers. Preferred curable mixtures of amine-modified acrylate resins with polyepoxides have amine numbers of from 1 to 250 mg KOH/g and epoxide values of from 0.1 to 4 mol/kg. The mixtures applied as coating films to metal substrates or plastics substrates, in particular, are radiation-cured with, e.g., UV light and an at least partial amine hardening of the polyepoxide compounds in the mixture is conducted by thermal conditioning at, e.g., from 50 to 120° C.

Abstract: An arrangement for positioning flat articles, transported inside a container with straight sides. For a gentle positioning of flat articles of varied thickness and mass, which are transported at high speed into the container having a pivot bearing is provided. The location of the pivot bearing, the length and the pivoting range of the rigid member are selected such that for a return movement of the article out of the container, the pivot bearing is located in the return movement direction in front of the point of contact on the side. As a result and owing to non-reversibility, the article is clamped between the container wall or between the articles present therein and the rigid member (2).
