A method of making an elastic laminate includes the steps of feeding a fir st substrate in a machine direction, feeding a second substrate aligned with th e first substrate in the machine direction, and feeding an array of elastomeric stra nd material stretched in the machine direction between the first and second substrates. A hot melt adhesive is applied onto the strand material, and a curable adhesive is applied to one or both of the substrates. The two substrates and the elastomeric strand material are then compressed to form an elastomeric preform web while maintaining the elastomeric strand material in its stretched state. The stretched elastomeric preform web is then heated in line by feeding it over heated rolls, and thereafter allowed to relax and contract in the machine direction as it cool s and moves downstream from the heated rolls to form a gathered elastomeric laminate. A release liner is fed in the machine direction and aligned with the gathere d elastomeric laminate, and a pressure sensitive adhesive is applied to the release liner. The gathered elastomeric laminate and release liner are then compress ed to form the elastic laminate which is particularly useful as window flashing.</ SDOAB>
