More Information
Summary:A special trawl net for collecting floating products has a dorsal or upper face of a close-mesh netting which extends over the two wings of the trawl and forms on the ventral or lower face thereof two lateral strips separated by a central net zone having a wider-mesh netting, so that water can easily escape therethrough. An impervious sleeve surrounding the bag formed by the trailing end of the trawl, and extending beyond this trailing end, is connected to the bag at one end and is open at its other end. This sleeve makes it possible to sealingly enclose the bag when the latter is filled with the products to be collected.
