Abstract
The starting material consists of a multistrand elastic tape (7) which is fed by the apparatus (11) and then separated by the successive separators (20, 24, 30, 31, 32, 33) into two arrays (35, 36) of four individual elastic strands. Each individual strand passes into a longitudinal groove of an adhesive application unit (37, 38), the strands passing out completely coated with hot melt liquid adhesive at high temperature. Adhesive bonding to the flexible sheet (1) moving in the direction of the arrows (2) is effected as soon as contact is made with the said sheet. A diaper pantie is obtained which on each side of the absorbent pad has a plurality of elastic strands disposed side by side.
