    摘要： A method of producing steel-wire-reinforced conveyer belts. The steel wires, which are conveyed at a uniform tension through the production apparatus, each have associated with them a respective hydraulic tensioning cylinder. The cylinders, which communicate with one another, are acted upon by a pulsating fluid pressure. In this way, varying movement resistances can be reduced, resulting in extensive uniformity of the tension state of all of the wires.

    摘要： A process for bonding metal strip or panels containing inflatable passageways, wherein the passageway may be uninflated, partially inflated, preformed, or fully inflated. The strip or panels are eventually fully inflated to form one or more fluid passageways. The strip or panel is maintained under tension and is bent by contacting it with a die spindle while it is under tension. The strip or panel will be forced ahead and around the die spindle, thus creating elongation. Upon completion of the bend, the strip or panel may be inflated using air, water, or any other inflation medium. The inflation can be accomplished while the strip or panel is still under tension, or they may be freely inflated after removal of the tension. An apparatus for carrying out the process comprises a die spindle shaped to substantially mate with the strip or panel which is to be bent. The die spindle is secured to a rotatable bending arm, which is adapted to traverse the die spindle through an arc, which intercepts the strip or panel, forcing the strip or panel ahead and around the die spindle. The apparatus also contains means for 4879888X tension to the strip or panel while it is being bent. The tension is preferably slightly less than the yield strength at 0.2 percent offset of the strip or panel. The apparatus is also capable of automatic and continuous operation and is ideally suited to the formation of serpentine-like configurations for use in heat exchangers.

    摘要： IN ORDER TO FRAME A FOIL PORTION WITH A MIRROR SURFACE, A FOIL IS PERFORATED ALONG A CIRCULAR LINE, A MARGINAL ZONE OF THE FOIL IS FRICTIONALLY HELD WITHIN THE ENDLESS LINE, THE FOIL IS CUT ALONG THE ENDLESS LINE, AND THE MARGINAL ZONE IS FIRMLY CLAMPED AND MOVED OVER A FIRST FRAME PART AND TENSIONED, WHEREUPON A SECOND FRAME

    PART IS PRESSED AGAINST THE FIRST FRAME PART AND CLAMPS THE TENSIONED FOIL TO THE FIRST FRAME PART WITHOUT ANY WRINKLES OF FOLDS.
