so that the rolls do not compact the absorbent portion but where the impregnated nonwoven cover material and polyethylene backing sheet need to be pressed firmly into contact with each other the rolls are lowered under pressure to apply such compacting forces appropriate timers and control mechanisms switches and sensing devices are inter connected to the drive train wheels gears rolls applicator head etc so that the barrier length and width thicknesses quantities and amounts are completely controllable and variable so that the location of the hot melt on the web the quantity and pentetration thereof are carefully controlled it is to be understood that the position location speed and temperatures of the hot melt and the cooling rolls 54 and 55 are precisely arranged so that the impregnant does not penetrate less than 5 and not more than 95 of the thickness of the nonwoven and so that the hot melt material still remains slightly tacky as the partially impregnated coverstock material and the plastic backing sheet are brought together between the compression rolls 58 59 and 60 thus effecting bonding the nonwoven cover with its impregnant is laid on top of the pads 31 and the plastic backing sheet 32 with the soft non impregnated side of the nonwoven cover uppermost and with the impregnated side facing downwardly so that its comes into contact with the plastic backing sheet 31 and to a limited portion in the areas defined and described above on top of the edges of the absorbent pad 31 it is.
