Abstract

The mandrel, used for moulding a hollow body by filament winding, can be removed after moulding and reused. It is formed of a wire assembly which when placed under internal tension defins the form and volume of the piece to be moulded. The use of the mandrel removes the need for one which is destroyed after use, or the need to employ a thick and costly support e.g. of rubber. A number of associated mandrels may be used to form a tank with a number of compartments. Any type or size of cable or ribbon may be tensioned hydraulically, pneumatically or mechanically, esp. by using tensioning arms attached to the axis of an extender. The equipment may be removed through a manhole after moulding.
