KAMBEROLLER® GUIDING INSTALLATION AND DESIGN SPECIFICATIONS INSTALLATION INSTRUCTIONS

1. Assembly The KAMBEROLLER® assembly consists of three essential components which are: A. Raceway Assembly The Raceway Assembly is sized to suit exact loadingconditions. Standard raceway bushings are antifriction and are prelubricated for life. B. Roller (or Rollers) Rollers are designed to suit material, width, and tension. Standard roller deflection is limited to no more than 0.005 inch per inch of roller face based on stated tension. Standard roller bearings are prelubricated for life. C. Hydraulic Cylinder or Electromechanical Actuator The cylinderor actuator is sized to handle the load at the required correcting speed. 2. Installation A. Entering Span (L) The KAMBEROLLER® must be installed according to the following: (1.) After a long, free, entering span. The length of the span is determined by the required maximum correction to be made and the line tension, as well as the characteristics and dimensions of the material to be guided.Typical entering spans for normal correction requirements are: WovenTextiles 1 to 2 Web Widths Plastic Films 1.5 to 3 Web Widths Paper and Board 2 to 5 Web Widths Metals 10 to 30 Strip Widths (2.) It is desired that the free span (pre-entry) just prior to the entering span be shorter than the entering span. This will prevent undesirable feedback through the web or strip. Such undesirable feedback mayinduce large errors in the same direction the KAMBEROLLER® is correcting, causing it to go to the extreme of its stroke, thus passing through large uncorrected errors. (3.) It is desirable that the web wrap the fixed entering idler a minimum of 45°,and preferably 90° or more. B. Exiting Span (L2) This span is the free span from the guide assembly to the next idler roller with sufficient wrap so theguide roller action cannot cause web slippage across it. The length of the span required is a fraction of the entering span, and for a 90° KAMBEROLLER® installation can be as little as 1/3 web width for woven textiles to 2 strip widths or greater for metals C. Center of Rotation The point about which the guide assembly rotates in reaching the angular position required for a given correction isthe Center of Rotation. Generally, locating the Center of Rotation of the

KAMBEROLLER® from 2/3 to 3/4 of the entering span length ahead of the guide roll will assure satisfactory dynamic performance. (Distance L1 on the diagram on page 1 of this Figure Sheet.) D. Sensor and Deadbar or Support Roller The sensor should be fixed and located as near to the guide as possible. Generally, any...
