<p>The equipment which collects marine algae from waves, has a net supported by a metal frame. The rectangular sections (7) forming the frame (4) are joined together by hinges allowing up and down movement. There can be two or more such sections on opposite sides of the central one, the side ones folding in an accordeon pattern against it. They can be held in the working position by an suitable means such as lugs. The design allows easy folding for transit by road.</p> |
