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.

Method for winding elastomeric ribbon

Apparatus for inserting elastic strips into elastic leg diapers wherein elastic strips are adhesively secured continuously along the crotch area and in relaxed condition along the waist areas including a mechanism for feeding a continuous strip of elastic at a constant rate, a mechanism for feeding a continuous sheet of diaper material at a constant rate, and an oscillating arm for guiding the sheet of diaper material and inducing periodic variations in the velocity or distance of the diaper material with respect to the elastic feeding mechanism, thereby alternately stretching and relaxing predetermined lengths of continuous elastic strips as they are adhesively secured to the diaper material.
