Abstract

PURPOSE:To mechanize the step of folding an edge of a tatami mat which is only of steps in a tatami manufacturing process that has not yet automated. CONSTITUTION:This method for folding an edge of a tatami mat comprises the steps of rasing an edge fabric tape starting from the inside of each side of a tatami mat at which the edge fabric tape and base paper are sewn and of moving to the side while the edge fabric tape is clamped so as to form a crease. Then the clamp of the tape is released, and the returning is made to a position around the start point. Then the tape is again clamped and then the movement is made in an opposite direction while a crease is formed so as to fold the edge of the tatami mat. Further, a device for folding an edge of a tatami mat comprises a tatami table 1 for positioning a tatami mat to which an edge fabric tapes are sewn, an edge retaining member 2 and an edge raising member 3 which are opposed to each other on both sides of the stitch on the edge fabric tape as a border, a drive device for moving these members to and away from each other, laterally of the stitch, and a control device for the tatami table and the drive device.
