    • A preformed heat shrinking protective cover for a saw blade includes first and second portions each having opposite inner and outer surfaces. The second portion extends from the first portion at an angle relative to the first portion. The first and second portions are configured and adapted for a saw blade to be positioned in contact with the inner surface of the first portion. The first and second portions are made from a heat shrinking material so that when heat is applied to the cover, the second portion shrinks and folds over the first portion with the inner surfaces facing each other and teeth on a saw blade can be retained between the first and second portions. The resulting cover is close fitting and reduces the overall thickness of a saw blade with a protective cover.
    • 用于锯片的预成型热收缩保护罩包括分别具有相对的内表面和外表面的第一和第二部分。 第二部分相对于第一部分以一定角度从第一部分延伸。 第一和第二部分被构造和适用于锯片被定位成与第一部分的内表面接触。 第一部分和第二部分由热收缩材料制成,使得当热量施加到盖子时,第二部分收缩并折叠在第一部分上,内表面彼此面对,并且锯片上的齿可以保持在第二部分之间 第一和第二部分。 所得到的盖子是紧密配合的,并且通过保护盖减小锯片的整体厚度。
