A joint sealing key assembly includes a sealing key having a sealing face and one or more posts projecting in a direction away from the sealing face. The sealing key is disposed in a key slot of a first part with the post extending into an opening through the bottom of the key slot. The post include
A joint sealing key assembly includes a sealing key having a sealing face and one or more posts projecting in a direction away from the sealing face. The sealing key is disposed in a key slot of a first part with the post extending into an opening through the bottom of the key slot. The post includes a laterally opening elongated hole for receiving a lateral pin to retain the sealing key in the slot during assembly. Upon formation of the joint by bringing the seal faces of the first and second parts together, the sealing key is displaced against the bias of a leaf spring thereby retaining the sealing face of the sealing key in sealing engagement with the seal face of the second part.

The method as claimed in claims 4 or 5, characterized in that the central section, located in the region of at least one release cutout, of the leading edge region is supported by an actively or passively moved supporting finger immediately before being bent away. 8. The method as claimed in claim 1, characterized in that the stack of products rests with its underside on supporting means which move in the direction from the leading edge region to the trailing edge region of the products in the stack of products and are provided with release apertures, a product being bent away when the leading edge region comes to lie in the region of the release aperture. 9. The method as claimed in claim 8, characterized in that the stack of products rests with its underside on a number of carrier rolls, which are fixed to a conveying element and, by means of the latter, in the region of the stack of products are moved from the leading edge region to the trailing edge region of the products in the stack of products, the release apertures being formed between two adjacent carrier rolls or carrier-roll groups. 10. The method as claimed in claim 1, characterized in that the suction element which attracts a product and the gripper which grips the same product move on a common conveying path or on conveying paths that run parallel to each other during the transfer of the product from the suction element to the gripper. 11. The method as claimed in claims 1 or 10, characterized in that the suction element which attracts a product and the gripper which grips the same product move approximately centrally along the underside of the stack of products during the transfer of the product from the suction element to the gripper. 12. The method as claimed in claim 1, characterized in that the suction element is pivoted between picking up the product from the stack of products and transferring the product to the gripper. 13. The method as claimed in claim 12, characterized in that suction element is pivoted in such a way that a product is transferred to a gripper that follows in the transport direction. 14. The method as claimed in claim 12, characterized in that the suction element is pivoted in such a way that a product is transferred to a gripper that leads in the transport direction. 15. The method as claimed in claim 1, characterized in that the product stack is loosened by an upwardly directed intermittent force acting on the product stack at least in some portions of the underside of the product stack. 16. A device for transporting away flat flexible products, especially printed products, stored in a product stack comprising: a supporting device for supporting the product stack on its underside in its lateral regions and having at least one release cutout or release aperture, a plurality of grippers movable along a gripper conveying path running underneath of the product stack, and a plurality of suction elements movable along at least one suction element conveying path running underneath the product stack, at least some portions of the suction element conveying path running along or parallel to the gripper conveying path, whereby the section of the gripper conveying path and of the suction element conveying path arranged underneath of the product stack extends along the central section of the product stack. 17. The device as claimed in claim 16, characterized in that a suction element transport wheel and a gripper transport wheel are provided, which convey suction elements and grippers along the respective conveying paths. 18. The device as claimed in claim 17, characterized in that the suction element transport wheel and the gripper transport wheel are designed as a single transport wheel for conveying both the suction elements and the grippers. 19. The device as claimed in claim 16, characterized in that the supporting device; comprises at least one rotating supporting disk which has at least one release cutout and which supports some portions of the underside of the stack of products, and also has a support table, which is provided to support the stack of products at its underside in a region not supported by the supporting disk. 20. The device as claimed in claims 16, 17, 18 or 19, characterized by means for producing a periodic movement oriented at right angles to the underside of the stack of products. 21. The device as claimed in claim 19, characterized in that two supporting disks each having at least one, especially two diagonally opposite, release cutouts are provided, and rotate in opposite directions in such a way that in each case a release cutout in each supporting disk comes to lie simultaneously in the central section of the leading edge region of a product. 22. The device as claimed in claim 19, characterized in that supporting disk and/or support table are provided on the side of the stack of products with friction-reducing means, especially with compressed-air outlets. 23. The device as claimed in claims 16 or 19, characterized in that, in the region of the central section of the leading edge region, an actively or passively moved supporting finger is provided to support the stack of products. 24. The device as claimed in claims 16 or 19, characterized in that, in the transport direction of the suction elements and of the grippers, a deflection roll is provided with an offset with respect to the leading edge of the stack of products, its axis extending at right angles to the transport direction of the suction elements and of the grippers. 25. The device as claimed in claim 16, characterized in that the supporting device; comprises a number of carrier rolls which are fixed to a conveying element and form a type of roller carpet, on which the stack of products rests with its underside, release apertures being present between two adjacent carrier rolls or carrier-roll groups. 26. The device as claimed in claim 25, characterized in that in each case a flexible drive element provided with the carrier rolls is arranged on both sided of the stack of products, the carrier rolls of the two flexible drive elements being oriented toward each other in the region of the stack of products. 27. The device as claimed in claim 26, characterized in that the flexible drive elements run in a plane parallel to the suction element conveying path, the carrier rolls in each case being freely rotatably mounted on a carrier arm of an angled lever that is fixed pivotably to the flexible drive element, and in that there are guide elements for pivoting the angled lever and the carrier rolls into a position that releases the transport away of the products. 28. The device as claimed in claim 26, characterized in that the flexible drive elements run in a plane that forms an angle with the suction element conveying path, the carrier rolls being freely rotatably mounted on carrier arms that are firmly connected to the respective flexible drive element and form an angle with the flexible drive element plane. 29. The device as claimed in claim 25, characterized in that means are provided by means of which the freely rotatably mounted carrier rolls are set rotating in a direction opposite to the onward movement of the flexible drive elements in the area of contact with the underside of the stack of products. 30. The method as claimed in claim 1, characterized in that the product is bent away through an angle of between 60° and 120° before it is gripped by the gripper. 31. The method as claimed in claim 30, characterized in that the product is bent away over a deflection roll before it is gripped by the gripper.
