Screen and frame assembly in which the screen is adhesively secured to the frame

A screen and screen frame assembly comprising:

• a plurality of screen bar segments, each formed so as to have a stress-free outwardly bowed state and a stressed state in which the segment is substantially straight, the plurality of screen bar segments being secured together to form the screen frame, each of the plurality of screen bar segments including a tensioning step along one side thereof;
• adhesive applied along the base of the tensioning step of each of the screen bar segments;
• and
• screen comprising open weave ventilation material spread across the screen frame, tensioned and bonded to the base of the tensioning step of each screen bar segment by the adhesive, so that the screen bar segments are in the substantially straight stressed state when the screen is bonded to screen bar segments, the portion of the screen in contact with the adhesive being encapsulated by the adhesive, for each of the plurality of screen bar segments.

A screen and screen frame assembly comprising:

• a plurality of segments of screen bar secured together to form a screen frame, each of the plurality of screen bar segments including a tensioning step along one side thereof;
• hot melt adhesive applied along the base of the tensioning step of each of the screen bar segments, the adhesive being applied in an amount to provide a layer having a sufficient thickness so that strands of screen are encapsulated by the adhesive when screen is secured to the screen bar;
• and
• screen comprising plasticized polymer coated open weave ventilation material spread across the screen frame, tensioned and hot melt bonded to the base of the tensioning step by the adhesive such that strands of screen are encapsulated by the adhesive, for each of the plurality of screen bar segments.
