1) Flange 1
2) Stiffener
3) Fabric material
4) Flange 2
5) Possible special fixing to facilitate the mounting of the first steel lamination

P.A. = Open length
B =
Outside width
P.C. = Closed length
Stroke = Open length – closed length
a = Outside height
x = Fold height

x(mm) 15 20 25 30 35 40 45
L(mm) 16 21 26 33 43 48 56
Z(mm) 45 55 65 75 85 95 105

Formula for calculating the CLOSED LENGTH

AP = Opening of 1 fold = x . 2 – 16
SM = Fabric thickness *
SS = Stiffener thickness *
SF = Flange thickness *
NP = Number of folds = (P.A.: AP) + 2
P. C.= (SM . 8 + SS) . NP + (SF . 2)

* see materials

* We hypothesize the fabric material with code “TEMAT151” (see materials)
** We hypothesize that the stiffener is 1 mm thick
*** We hypothesize that the flange is 2 mm thick (see materials)
