Abstract
A return guiding device for reversing the direction of travel of flat metal material and suitable in particular for inserting metal strip into so-called S-roller frames consists of a return guide shell having an area of small width occupied by rollers, so that during guidance the corners at the leading edge of the strip do not rest on the rollers but only on smooth edge regions of the return guide shell.
Claims7
A guiding device for reversing the direction of travel of flat metal material, comprising:
- a guide shell having a curved inner surface;
- and a plurality of rollers freely rotatably mounted in said guiding device to project from said curved inner surface of said guide shell, wherein said plurality of rollers occupy on said curved inner surface an area having a width which is smaller than the width of the narrowest strip of flat metal material intended to be guided by said guiding device, and wherein a smooth edge region of said curved inner surface extends unbrokenly along both sides of said area occupied by said plurality of rollers, and is free of said rollers.
In a roller traction device, a cylindrical traction roller;
- and a guiding device mounted in closely spaced relationship to said traction roller, said guiding device including:
- a guide shell having a curved inner surface presented to the outer surface of said traction roller in closely spaced relationship;
- and a plurality of rollers mounted centrally of said guide shell to project from said curved inner surface thereof, said rollers being mounted for free rotation about axes extending parallel to the axis of said traction roller and defining an imaginary curved surface disposed closer to said traction roller than said curved inner surface of said guide shell, said plurality of rollers occupying an area on said curved inner surface of said guide shell having a width which is smaller than the width of the narrowest strip of flat metal material intended to be guided by said guiding device, and the end regions of said curved inner surface of said guide shell along both sides of said plurality of rollers being smooth and unbroken.
