Abstract

PURPOSE:To produce efficiently economically a buffer for corner by applying a heating blade to a foamed sheet of polyolefin system resin and fusing it to be bent along the line of application of the blade while the resin is in soft condition. CONSTITUTION:A foamed sheet 1 of polyolefin system resin such as polyethylene foamed sheet, polypropylene foamed sheet, etc. is subjected to the application of a heating blade 2 heated to at least melting temperature of the sheet 1 to be fused and bent inwards along the line of the application of the blade 2 when it is still in the soft condition, and cooled.
