A directional air knife, components thereof, and associated methods. The air knife includes a housing that comprises an inlet opening which receives air under pressure into the housing along a first inlet axis. A chamber is defined within the housing and positioned to receive air that passes through the inlet opening along the first inlet axis. A discharge duct is defined by the housing and includes a discharge channel within the discharge duct. The discharge channel is in fluid communication with the chamber which receives the air under pressure. The housing defines an outlet opening through which the air under pressure passes out of the discharge duct. The discharge channel has a second central axis along which the air under pressure flows to the outlet opening and out of the housing. The second central axis is arranged with respect to the first inlet axis at a skew angle.
A directional air knife for use in applying air to an edge of a film as the film is being formed, the directional air knife comprising a housing including an inlet opening for receiving air under pressure into the housing along a first inlet axis, a chamber defined within the housing and positioned to receive air passing through the inlet opening along the first inlet axis, a discharge duct defined by the housing and including a discharge channel within the discharge duct in fluid communication with the chamber for receiving the air under pressure and an outlet opening through which the air under pressure passes out of the discharge duct, the discharge channel having a second central axis along which the air under pressure flows to the outlet opening and out of the housing, the second central axis being arranged with respect to the first inlet axis at an angle that is neither parallel with nor at right angles to the first inlet axis.
A directional air knife for use in applying air to an edge of a film as the film is being formed, the directional air knife comprising a housing including an inlet opening for receiving air under pressure into the housing, a chamber defined within the housing and positioned to receive air passing through the inlet opening, a discharge duct defined by the housing and including a discharge channel within the discharge duct in fluid communication with the chamber for receiving the air under pressure and an outlet opening through which the air under pressure passes out of the discharge duct, the housing including an inlet portion containing the chamber, the discharge duct extending from the inlet portion, the inlet portion of the housing having laterally opposite end surfaces, the discharge duct projecting laterally outward from a projection of one of the opposite end surfaces of the inlet portion of the housing, a first of the end surfaces being located opposite of the inlet opening, the first end surface being curved to an intersection with the discharge duct.
