  • each bearing member 120 is preferably fed by a tray or a conveyer belt such that the contact surface 121 thereof is oriented upwards with respect to the bottom of each bearing member groove 232 so as to allow the contact surface 121 thereof corresponding to the rupture-proof ridge 122 to be heated by the heating means 220.

  • the footing members are bonded to the bearing members, which are arranged at regular intervals, with a predetermined width in a grid shape, so that the mat can be manufactured.
