Abstract
An air knife constructed in accordance with the present invention directs a curtain of air across a region and most typically is used to direct the stream of air against a surface. In an exemplary embodiment of the invention the air knife includes an elongated housing having an inlet for receiving air into the housing. The housing includes an elongated gap that extends along the housing that allows air entering the housing through the inlet to exit the housing and form a curtain of air. The elongated housing is made from a piece of sheet metal bent to define a hollow region into which air is forced. The sheet metal defines a gap along a length of the housing from which the air exits. The elongated air knife forms an angle with respect to a direction of travel of glass sheets passing the air knife so that a leading edge of those glass sheets passes progressively different parts of the air knife.
