ABSTRACT:
A method of releasably connecting together strips of material comprising arranging the strips with surfaces facing each other and forming upwardly deformed areas of the strips above their planes and downwardly deformed areas of the strips below their planes, the deformed areas having intervening tie portions arranged at angles to the planes of the sheets, the tie portions being partially cut out to form tongues and interlining shoulders and remaining connected to the strips between deformed areas whereby upon relative longitudinal movement of the sheets, the tongues are displaced to seal against the shoulders and the inclined tie portions are adjacent to each other.
