EXAMPLES
The cutting of the slats should be marked to ensure that
the curtains are fabricated symmetrically.
To do this we will need the number of perforations
= L/145 mm
, with L being the Length of the curtain, and
we will round up the total.
Then we check whether the number of perforations is even
or odd and place ourselves in the middle of the number of
perforations.
If the number of perforations is even, we will place
ourselves in the middle of the partition and proceed
to measure and mark half the length of the curtain on
both sides.
Length of curtain:
2,000 mm
Number of perforations:
L/145 = 2,000/145 = 13.79 = 14
(Number of perforations is even).
Number of perforations/2:
14/2 = 7
(So we will count 7 whole perforations and place
ourselves in the centre of the partition).
L/2 = 2,000/2 = 1,000 mm left and right.
Length of curtain:
3,000 mm
Number of perforations:
L/145 = 3,000/145 = 20.68 = 21
(Number of perforations is even).
Number of perforations/2:
21/2 = 10,5
(So we will count 10.5 perforations (10 whole plus one
half) and we will place ourselves at the centre of the per-
foration).
Next we will measure L/2 on both sides and mark the
slat. L/2 = 3,000/2 = 1,500 mm left and right.
We will place ourselves in the middle of the perforation
and proceed to measure and mark half the length of the
curtain on both sides.
