发明名称 Process for producing curved sections in hollow profile strips
摘要 In order to curve a hollow profile strip (53), especially a hollow profile strip (53) from which a spacer frame for an insulating glass pane is to be produced, the hollow profile strip (53) is conducted continuously for an exactly defined length, held laterally and from the bottom, underneath a roller (70) and, subsequently to the roller (70), is deflected out of the conveying direction. An apparatus suitable for this purpose comprises a gripper (52) for the defined feeding of the hollow profile strip (53), a roller (70) in contact with the wall of the hollow profile strip (53), which is then located on the inside of the curvature, and holding down the hollow profile strip (53), and a lever (59) with a stop surface (62) for the hollow profile strip (53) subsequently to the roller (70). By selecting the extent of feeding of the hollow profile strip (53) and by the extent of deflection of the same, the length and/or the radius of curvature of the curved section (71) of the hollow profile strip (53) can be determined.
