Abstract: Three metal foils are simultaneously fed in opposing relationship through a machine which automatically fabricates a sheet metal sandwich structure therefrom. The foils are first tensioned in aligned opposing relationship. The center sheet is then fed through a pair of free floating gear shaped corrugator tools which form corrugations or undulations therein. Adhesive is then applied to the inner surfaces of the two outer foils and the three foils passed through a pair of drums which press the foils together between opposing metal bands and provide uniform heat thereto through the bands to effect curing of the adhesive. The foils are further pressed together between the bands by means of air diaphragms or bladders which provide hydraulically controlled clamping force thereto. Finally, the sandwich structure thus formed is trimmed and cut to form boards of the desired width and length.

Abstract: A machine in which butterfly clips are prebent and then punched out of steel strip and simultaneously finally bent, such that they fasten together a spring and the frame of a spring core. Thus, both the punching out of the clip and the final bending process, i.e. the connecting process between the frame and spring parts, are carried out in a single tool. The machine therefore operates particularly cost-effectively, because, in comparison with the prior art, the separately punched butterfly clips do not have to be inserted into a separate bending machine.

Abstract: A slitting apparatus for an amorphous metal strip employs a scribing tool to form a scribed line in a surface of the strip as it is transported past the scribing tool. The scribed strip is folded toward the scribed line and creased between mandrels. Then the crease is flattened out against a flattening surface, whereupon the strip cleanly separates into first and second strips. A separating device downstream of the flattening surface moves the newly separated edges apart. A functional relationship between at least some of the radius of the cutting edge of the scribing tool, the scribing force, the tension in the strip and the separating device is described and empirical methods for maintaining these elements with effective operating ranges are given.

A milling machine cuts away at least approximately 75% of the total volume of metal to be removed from the surface of the initial strip of metal. This forms a pattern corresponding to the multiple gauge surface desired in the strip product. Then, the milled strip is passed into a shaving device which is located in axial alignment with the milling device. The shaving apparatus shaves off a maximum of about 25% of the total volume of metal to be removed from the surface of the milled strip in a single shaving pass to substantially form the desired configuration of the strip product.

The bending device is removable and can easily be replaced by another one which has been reset in a preceding working process. Therefore standstill periods of the machine are reduced.
