<p>A tarpaulin comprising a fabric coated with a plastics material, preferably PVC, polyamide or polyprene, is provided with a decoration of a reflecting material by anchoring a reflecting sheet to a piece of tarpaulin cloth, whose plastics coating is of the same type as or is compatible with that of the tarpaulin, by high frequency welding or heat application, and then applying the piece of tarpaulin cloth provided with reflecting sheet, optionally formed in the desired shape, to the tarpaulin by hot air fusion. The reflecting sheet is preferably a retroreflecting PVC sheet of the naked prism type which is anchored to the piece of tarpaulin cloth by high frequency welding. Other types of reflective sheet may be applied to the piece of tarpaulin or directly to the tarpaulin by means of an adhesive and anchored thereto by placing a transparent flexible polymeric film on top of the reflecting sheet with its edges extending beyond those of the sheet and high frequency welding it to the piece of tarpaulin or the tarpaulin itself along the edges.</p> |
