Reference numeral 1 denotes a fastening hole through which a fastening bolt is passed, and a hole having a diameter of about 15 mΦ is usually drilled using a punch or the like. 5-2 is a reinforcing material with sufficient strength to suspend a cheno weight, and has a strength of 100
Approximately 2 plies of polyester canvas with a weight of about 1.5 kg/cm are used, and 5-3.5-4 is a cover rubber sandwiching the reinforcing material 5-2, with a thickness of about 2 to 3 inches, seawater resistant and abrasion resistant. These are vulcanized and integrated under moderate pressure. Rubber plate 5 is JtJ 3-4C, length 20-3
Since the size of the rubber plate is about 0 cm, this production method allows for high efficiency by manufacturing a 111-wide rubber plate, drilling holes for fastening in it, and cutting it to a predetermined size.
裁断されたゴム板５の側面は、補強材５−２が露出し海
水に接触するので補強材は、耐海水性等を有するポリエ
ステル、ナイロン等の帆布がよい。Since the reinforcing material 5-2 is exposed on the side surface of the cut rubber plate 5 and comes into contact with seawater, the reinforcing material is preferably a canvas made of polyester, nylon, or the like having seawater resistance.
