Übersetzung für "Falzverbindung" in Englisch

The housing 2 and the cover 4 are connected to one another with a folded connection 5.

It can in particular be a flanging press for manufacturing a hemmed connection.

Seam locking has a mild pre-load and is nearly air- and watertight.

The welded joint was replaced with a mechanically folded joint.

The problem described above is solved by a folded connection according to the invention as shown in FIG.

It is preferred that the cut edge is covered in the connection area by a material which is preferably the sealing material of the hem.

In order to attain an even greater rigidity of the scarf joint also against compressive loads of the supporting arm, the folding pocket can, in an exceptional case, also be drawn into the duct interior from the duct wall.

The outer edge projections 10.1 are moisture-tight or damp-proof and are also preferably gas-tightly connected with a corresponding edge projection 11.1 of the outer plate 8.1 by a scarf joint in the form of a so-called casing seam, whereby an extended leg of the edge projection 11.1 reaches around the edge projection 10.1 in a U-shape, and is squeezed together therewith.

Due to the folded connection between the cover and the housing, the cover, together with the bushings soldered thereinto, must be fabricated of about the same material thickness as the housing.

The pull plate 7 has thin flat tabs 21 extending outwardly from the outer lower edges of the pull plate 7 for receiving the lower edges of the mould walls 5 in a temporary rabbet joint.

In a second operation cycle, the pipe segments are joined to the two flange-like brims which are matching so as to achieve a folded seam connection. In particular, a single border is inserted into a double border, the double border being clamped together at individual locations.

For closing the folded seam connection, cooperation of the fixed wheel 3, being in the pipe bend 38, with the pressing wheel 4 and the closing disk 5 is needed.

In this embodiment as well, the connecting fitting is provided on a cover which is connected with the housing or receptacle wall by a fold seam.

Especially when a metal foil is used for the cover, such a fold connection turns out to be advantageous to the easy creation of a connection of the two partial surfaces, with the connection permitting an increase in the inner volume of the cover.

Hitherto it has been usual to make the locked-seam connection between the hollow member of thin sheet metal and an intermediate ring consisting of equally thin sheet metal which has previously been welded to the thick plate.

The profiling device forms matching seamed edges or brims of the ribbon material which, after deformation of the ribbon material in bending direction, are mutually inserted, and are pressed together by the closing device, that has cooperating closing wheels, to form a folded seam connection.

In accordance with a configuration of the invention the mechanical connection can be formed by a welded connection, a bonded connection, a folded connection, a clamped connection or a beaded connection.

The method of claim 6, further comprising the step of attaching the tear-open lid (2) to the top edge by means of a folded joint (16).

In this way, nested parts which are joined to each other by flanging can for example, in addition to the hemmed connection thus created, also be fixed relative to each other in a material fit.

In the case of such components, an outer part and an inner part of the respective component are joined by flanging, i.e. by creating a hemmed connection.

FIG. 8 shows a flange region of the component B in which the flanging bed 11 and the flanging die unit 2 co-operate to join an outer part A and an inner part I to form a component B, a vehicle door, by folding over a flange C on the edge of the outer part A, such that an edge of the correspondingly positioned inner part I protrudes into a hemmed pocket of the outer part A which is thus created, and the parts A and I are fixed relative to each other by the hemmed connection thus created.

The bottom and the peel-off lid are each connected to the body by means of a folded joint, for instance, which is known to the person skilled in the art and does not require further explanation herein.

In order to provide containers which are produced helically from bent sheet metal strip and the range of application of which is increased, in particular with regard to the realization of a large storage volume and/or increased mechanical stability while ensuring nevertheless simple and rapid production capability and installation, solutions have been developed which replace the seam connection with a welded joint.

Against a pressure increase by CO 2 development past a certain limit value, an overpressure safety means is to be provided by means of which, in case of an unexpected pressure increase, pressure can escape from the container to the exterior before overloading of the seamed connection or bursting of the container can occur.

After the production of the folded connection, the components 5, 6 therefore do not have to be specially cleaned, and they can be handled before the adhesive is completely dry without resulting in the contamination of handling equipment or operators.

For a strong hem connection, it is not absolutely necessary for the rim strip 27 to be completely beaded, i.e. placed onto the interior body part.

This process is repeated two or three times, wherein the turning-over angle becomes tighter and tighter, until the hem is finally closed or, if a hem connection is not being produced, the desired bending angle has been obtained.

Wherever the invention has been explained above with respect to a hemming device, these embodiments also apply analogously to a flanging device, i.e. to a device by means of which a hem connection can be formed but which can also serve to merely bead the component rim by a predetermined angle.
