Abstract

The net for collecting rubbish from water has two side trawls (1) which are long. Approximately two thirds of the width of the net is submerged. The upper and lower deges of the trawls contain cord which is attached to the net. The main part of the trawl (6) is of prismoidal shape and the bottom part is submerged. The mouth of the trawl (5) and the side trawls are kept open and in the correct position by weighted buoys (3). Around part of the trawl are rings (8) through which may be threaded a cord so that the debris may be held in place.
