ABSTRACT:
A window covering cutting and bonding apparatus includes a release sheet on an adhesive tape on an upper end and a bottom end of a window covering assembly. The release sheet is extended inwards from one side of a top end and a bottom end and bent and extended outwards to extend to outside the ends of an upper rail and a lower rail and form a preset pulling strip. Before a window covering is cut and trimmed, the release sheet can be moved in a skewed manner through the preset pulling strip. After the window covering assembly is cut and trimmed, the preset pulling strip can be pulled outwards to peel off the release sheet quickly at the same time. Therefore the adhesive tape can be exposed to bond to the upper rail and the lower rail of the window covering.
