Abstract
A method for manufacturing a sheet-formed buffer material using a gelled material wherein a thermally flexible and weldable covering sheet is applied to each of both surfaces of a flat gel material layer made of gelled material with penetration value of 50 to 200 and a buffer layer is thus made, said buffer layer being divided from above said covering sheet by a dividing means having a thermally welding means whereby said buffer layer is divided by said dividing means to form separate cells and simultaneously said covering sheets of the divided portions are welded by said thermally welding means to form dividing grooves between separate independent cells.
