  • Patent number: 4645135
    Abstract: A method for winding soft elastomeric ribbon on spools of substantially greater width than the width of the ribbon is provided which includes the winding of the ribbon on a surface driven spool. The ribbon passes through guides from a feed source, with the guides in proximity to the take-up spool. Traversing of the ribbon is provided by either shifting the guides or the take-up apparatus across the horizontal length less than the length of the spool to prevent overrunning of the outer edges of the spool. The invention also includes the spool wound with soft elastomeric ribbon to a thickness several times that of the ribbon and along a length several times greater than the width of the ribbon.
