A flat strap is provided to extend co-extensively of the panel. The ends of the strap are secured to the heavy gauge steel end caps which bracket the side ends of the panel, so as to lie flatly thereagainst. A jack device is positioned between the strap and the central portion of the panel. The jack device is extended axially to bias the strap away from the panel, whereby a force is applied perpendicularly to the central portion of the panel face, thereby preventing the panel from bowing inwardly and maintaining it straight, thereby maintaining the seal of the panel against the door opening frame.
Courroie plate pour déplacer, dans les mêmes proportions, un panneau. Les extrémités de la courroie sont fixées aux équerres de renfort d'extrémité d'acier fort des petits côtés du panneau, afin de reposer à plat. Un vérin est placé entre la courroie et la partie centrale du panneau. Le vérin s'étend en direction axiale pour éloigner, en biais, la courroie du panneau. Une force est ainsi appliquée perpendiculairement sur la partie centrale de la face du panneau, afin d'éviter que le panneau ne bombe vers l'intérieur et pour le maintenir droit, et le joint d'étanchéité du panneau est maintenu contre le cadre d'ouverture de la porte.
