Abstract: A process for the application of a releasable adhesive layer to the floor abutting surface of a ceremonial roll that can be easily unrolled and used to cover a walkway to provide a ceremonial cover therefor is described. This process employs elevated pressures and temperatures within a given time frame to laminated this adhesive layer to the floor abutting surface of the roll. This adhesive is then pressed onto the floor of the walkway itself before the roll is rolled down the aisle or walkway to be used. The adhesive will hold to the floor during the unrolling but can easily be removed by pulling up at an angle of greater than 30.degree. from the floor without being removed from the floor abutting surface of the roll. The adhesive will resist from 10 to 300 pounds of pull at angles less than this 30.degree.. The ceremonial roll may be made from a host of materials but a non-woven, fabric like materials made from long, natural and synthetic fibers are preferred.
