Abstract:
1. A method of making bamboo-surfaced layered Venetian blind slats having a curved cross-section comprising the steps of: (1) selecting bamboo slices, each having a length which is slightly longer than that of the slats to be made, each having a width which equals the total width of a plurality of the slats to be made, the length of the bamboo slices being parallel to the bamboo fibers; (2) selecting filling slices having fibers, each having a length and width which are identical to those of the bamboo slices, the length of the filling slices being parallel to that of their fibers; (3) selecting an adhesive and using the adhesive to adhere a bamboo slice, a filling slice, and a bamboo slice in turn to form a layered slat piece, wherein the fibers of each layer are parallel to the length of the layered slat piece; (4) placing the layered slat piece into a mold with a large surface area having top and bottom pressing surfaces, the top and bottom pressing surfaces each having a cooperating continuous shape formed from a repeating curved shape, and compressing the layered slat piece in the mold to form a curved plate with a large surface area; (5) cutting along the length of the curved plate with a large surface area to obtain bamboo-surfaced layered Venetian blind blank slats having a curved cross-section; and (6) trimming the remains of the cutting surfaces and the two end surfaces of the bamboo-surfaced layered Venetian blind blank slats to produce bamboo-surfaced layered Venetian blind slats having a curved cross-section.
