<p>#CMT# #/CMT# The arrangement has a screen, and a cylindrical roller (2) for winding and unwinding the screen and side rails on uprights of the screen. The rails extend parallel to each other from the roller and include a guidance profile mounted on a base profile with a light clearance. The screen includes local thickenings, present in the cavity, on its lateral edges. End fittings (17) have a hollow part (18) placed at the corresponding ends of the roller and a convex surface (19) directly connected to a cylindrical surface of the roller. #CMT#USE : #/CMT# Used for protection from light and high wind. #CMT#ADVANTAGE : #/CMT# The end fittings have a convex surface ensuring a more regular transition, between the cylindrical surface of the roller and the surface of the ends positioned towards the interior, and supporting the inclined edges towards the interior under the influence of the thickenings, thus preventing the formation of folds in the screen during a winding of the screen to prevent damage to the screen besides maintaining the esthetics of the screen. The guidance profile is mounted on the base profile with a light clearance, and so the guidance profile can be slightly moved opposite to the subjected elastic pre-stress to limit an overload of the screen. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an axial sectional view of the left end of the suspension of a roller. 2 : Cylindrical roller 4 : Side rail 17 : End fittings 18 : Hollow part 19 : Convex surface.</p> |
