  • Patent number: 9174258
    Abstract: A cold roll forming apparatus for forming a variable profile. The apparatus comprises a forming unit having a least one adjustment stand which includes a roll stand with a pair of rollers between which the sheet metal strip is passed through along its longitudinal direction (X), wherein the roll stand is translationally and rotationally displaceable during the cold roll forming with at least one translatory degree of freedom and one rotary degree of freedom being independent from each other.

  • Patent number: 9127936
    Abstract: Method for measuring an extruded profile using a measuring apparatus, wherein the measuring apparatus is designed to produce and measure at least two laser light sections on a surface of the profile, which is being pulled through the measuring apparatus, by means of at least one laser light section sensor from a respective, different position around the profile, wherein the at least two laser light sections are situated essentially in one plane. By positioning at least two references and/or reference markers from the adjacent positions together with the extruded profile in a respective common measurement capture area, said references or reference markers are used for calibration of respective raw image of the at least one laser light section sensor. Thus, the calibrated raw image data are correctly mapped in a common coordinate system from the respective position.

  • Patent number: 8214423
    Abstract: A computer aided design (CAD) system is described where each type of change in a CAD-generated object is automatically and chronologically protocoled so that the object directly includes an abstract description of the history of the object independent of the CAD module used. This is particularly advantageous with decentralized CAD systems in which several constructors/designers are working together on the same draft, but located in different places. At the end of a session, the object history, i.e., the changes which have taken place, are directly exported, together with the object data, into the destination system. The abstract description is in a form independent of the system used.

  • Publication number: 20110179842
    Abstract: The invention relates to a system for cold roll forming profiles having variable cross-sections, with several roll stands arranged in a row, each containing a pair of rollers, between which a sheet-metal strip (2) is guided along its length (X), wherein the roll stands are moved translationally transversely to the length of the sheet-metal strip and rotationally about an axis of the roll stand during cold roll forming. According to the invention, a re-forming device (8, 10, 12) is arranged behind at least one of the roll stands and has at least one drive for generating a movement of the re-forming device in a plane transversely to the length (X) of the sheet-metal strip.

  • Publication number: 20110088444
    Abstract: The invention relates to an apparatus for producing a profile by means of cold roll forming, said apparatus comprising a forming unit (9) having a least one adjustment stand (17, 17?, 17?, 17??) which comprises a roll stand including a pair of rolls between which there is a gap through which the sheet metal strip is passed along the length direction (X), wherein, during the cold roll forming, the roll stand is translationally and rotationally displaced with at least one translational degree of freedom and one rotational degree of freedom. According to the invention, the apparatus for forming a profile with varying height is configured so that the roll stand has one degree of freedom for rotation about an axis of rotation extending substantially in the direction of the gap between the rolls, said rotational degree of freedom being independent of the at least one translational degree of freedom. The invention also relates to a corresponding process.

  • Publication number: 20100083722
    Abstract: The invention relates to a device for bending flat semi-finished products into a profile having a changeable cross-section along the length thereof˜comprising at least one roll stand having profiling units in form of rollers and/or matrices. The semi-finished product can be led lengthwise between the profiling units. The invention further comprises at least two linear actuators (10, 12, 14, 16), arranged transversely to the length (Z) of the semi-finished product in order to produce translatory movements of the roll stand and rotational movements of the roll stand about an axis (Y) thereof. According to the invention, each of the at least two linear actuators are connected to the roll stand at a point provided at a distance from the axis (Y) of the roll stand.
