<p>PURPOSE:To ensure protection against a shock due to a drilling tool or corrosion by stacking a plurality of knitted clothes of synthetic resin yarn, and bonding the clothes to each other like a fine line along a lengthwise direction. CONSTITUTION:Three knitted clothes 11a to 11c made of synthetic resin yarn such as polyolefine synthetic resin are stacked on top of one another, and the center sections thereof are bonded to one another along a fine line with a bonding means, thereby forming a bonded section 12. The section 12 is formed via a bonding process including sewing with a sewing machine, an ultrasonic wave, an adhesive and thermal deposition. The section 12 is also bonded so as to be continuous along a lengthwise direction. In this case, the clothes 11a to 11c are made of yarn such as monofilament of thermal fusion synthetic resin knitted according to the case of looped fabric or the like, and the end section thereof is heat sealed to prevent a fray.</p> |
