Document Type and Number:
Japanese Patent JPS5040871
Kind Code:
A
Abstract:
Netting, made by bonding together crossing strands consisting of or containing thermoplastic material by means of individually moulded masses of thermoplastic material, is given enhanced bond strength by compressing the crossing strands together within the die cavities employed for moulding the thermoplastic masses. The improvement is particularly marked in the case of netting made from braided strands, for example of nylon, and intended for use as cargo nets. The compression may be applied by a pressure member, for example a fluid-actuated piston, mounted within the die. If desired, a pair of counteracting pistons can be used. After compressing the strands, the pistons may be withdrawn before the thermoplastic material is introduced or may be forced back by the entering thermoplastic material.
