Abstract
Light leaves of a Venetian blind and their manufacturing method, that is first to make a plastic basic plate by a plastic injection molding machine. Then, the plastic basic plate is cut in shape and punched with grooved slots to make up leaves of a Venetian blind. Each leaf is formed with two parallel long-stripped leaf surfaces and plural parallel separating plates formed integral between the two leave surfaces, having a through vent hole formed between every two adjacent separating plates and the two leaf surfaces. Such leaves are light and have functions of sound and heat insulation.
