L
|
0713:
Defines the real length
of the box, depending on the dimension type (DT).
However, the actual length of the base in the drawing is calculated by
taking into account not only L,
but also DT and FD,
and is measured through the Lss and Lss1 parameters.
When
the dimension type (DT) is 'score-to-score'
(dtSS=0), the result values of
L and Lss
are the same. Lss1
is preliminary shortened with one d
due to the fact that at the glue area a whole d
(one material thickness) is
added. Another words, Lss1 equals
L-d. When
DT is 'inside' (dtID=-1),
the length of the interior compartment of the folded box is equal to the
value of L and the actual base
length in the drawing ( Lss )
is equal to L+2d to allow the
folding of the two side flaps ( each "eating away" a d/2
area, thus a whole d ) as well
as to take into account the glue flap, adding on additional d.
That is how we ge Lss=L+2d. Lss1 equals L+d
because the folding of the glue flap and the side flap 'eat away' a whole
d , but at the glue area a whole
d (one material thickness) is added. When DT
is 'outside'(dtOD=-1), the overall
"outer" length of the folded box will equal the value of L and the actual base length in the
drawing ( Lss ) will be equal
to L-d to allow the folding of
the two side flaps ( each 'adding' a d/2
area, thus a whole d ). Lss1 is L-2d
because, on one hand, the folding of the glue flap and the side flap add
a whole d and on the other hand,
at the glue area a whole d is
added. As a result, a 2d portion
is added.

design, too.

W
|
Defines the real
width of the box, depending on the dimension type ( DT
). Just like L,
the actual width of the base, in the drawing, is calculated by taking
into account W, DT
and FD, but it is measured through
both Wss and Wss1
parameters. The difference between Wss
and Wss1 stems from the fact that
Wss1 takes into account only one
folding. W is used directly in
the expressions of the score-to-score width parameters Wss
and Wss1.

When
the dimension type (DT) is 'score-to-score'
(dtSS=0), the result values of
W, Wss
and Wss1 are
same. When
DT is 'inside'(dtID=1),
the width of the interior compartment of the folded box will equal the
value of W and the actual width
in the drawing (Wss) will be equal
to W+2d to allow the folding of
the two side flaps (each "eating away" a d/2
area, thus a whole d) as well
as to take into account the tuck end, "eating away" an additional
material thickness (d). Wss1 is also W+2d. When DT
is 'outside(dtOD=-1)', the overall
"outer" length of the folded box will equal the value of W and the actual base length in the
drawing ( Wss ) will be equal
to W-d to allow the folding of
the two side flaps ( each 'adding' a d/2
area, thus a whole d ). Wss1 is also W-d.

When
the dimension type ( DT ) is 'score-to-score'
(dtSS=0), the result values of
W and Wss
are the same. Wss1 is preliminarily
shortened to allow for the glue flap, adding one material thickness (d). When
DT is 'inside'(dtID=1),
the width of the interior compartment of the folded box will equal the
value of W and the actual width
in the drawing (Wss) will be equal
to W+3d to allow the folding of
the two side flaps (each "eating away" a d/2
area, thus a whole d), to take
into account that at the glue area a whole d
is added and also to allow for the tuck end, 'eating away' yet another
material thickness (d) . Wss1 will be W+2d
due to the two creases and to the glue flap, adding one material
thickness (d). When DT
is 'outside (dtOD=-1)', the overall
"outer" length of the folded box will equal the value of W and the actual base length in the
drawing ( Wss ) will be equal
to W-d to allow the folding of
the two side flaps ( each 'adding' a d/2
area, thus a whole d ) and to
take into account that at he glue area one d
is added. Wss1 is W-2d
to allow for the two creases as well as to the glue flap. As a
result, a 2d portion is added.
W
is only used in the expressions of the actual score-to-score length parameters
Wss and Wss1.

H
|
Defines the real
height of the box, depending on
the dimension type (DT). However,
just like the L and W,
the actual height of the base in the drawing is calculated by taking into
account not only H, but also DT and FD,
and is measured through the Hss
parameter.
When
the dimension type ( DT ) is 'score-to-score'
(dtSS=0), the result values of
H and Hss
are the same. When
the dimension type ( DT ) is 'inside'
(dtID=-1), the result values of
Hss is equal to H+d
to allow the folding of the two adjacent flaps ('each eating away'
d/2 portion, thus a whole d). When
the dimension type ( DT ) is 'outside'(dtOD=1), the result values of Hss is equal to H-3d
to allow the folding of the two adjacent flaps ('each eating away'
d/2 portion, thus a whole d) as well as to take into account that
crash lock panel and the lid add a 2d
portion.

DT
|
Defines the dimension type: inner (dtID = -1), outer (dtOD
= 1) or score-to-score (dtSS =
0). Since the material ( board ) of corrugated boxes is by industry standards
significantly thicker ( e.g. d=7 mm ) than folding carton boxes material
( most commonly d=0.5 mm ), there occur considerable differences between
the "interior" dimensions of the closed FEFCO box and the "exterior"
ones. This happens because creasing and double-creasing add to the outside
volume of the box. Therefore, you can choose among 3
dimension types to calculate the design, depending on which box size you
are interested in: the 'inside'
of the box (e.g. when your primary concern is the article that the box
is designed for), the outside
of the box ( e.g. when you are interested in the outer limits of the box
so that you can fit a number of such boxes into a bigger container), or
the score to score size (e.g.
the in-between dimension type where the system calculates the design without
taking into account the value of d;
for instance, the real box length parameter Lss
has the expression L+2*C90 - i.e.
the length parameter L value plus
twice the value of the correction parameter C90
which is equal to 0.00 when DT=dtSS,
a positive number when DT=dtID,
and a negative number when DT=dtOD).
DT
is a selection parameter - it uses the selection entries of the DimTypes
selection type, predefined in the Corrugated parameter template. The
3 predefined entries are as follows:
dtID - inside
dimension type. Use this dimension type when you seek to define
the dimensions of the interior "compartment" of the folded box.
The system automatically resizes the whole design according to the specific
corrections for inside dimension type, taking into account the additional
distances caused by the folding sides of the box. As a result, inside
dimension type makes the box design larger than with the other two options
( e.g. although the real length of the interior folded box compartment
will be equal to the value of L,
Lss has a bigger value than L because the system has to provide
for the area that is "eaten away" on folding due to the thickness
of the material ). dtSS - score-to-score
dimension type. Use this dimension type when you are not concerned with
the thickness of the material ( flute ) and you do not want the system
to take it into account when calculating the design ( in this case L=Lss
). dtOD - outside dimension type. Use this dimension
type when you want the dimensions you enter to define the outer shape
of the folded box. The system automatically resizes ( "shrinks"
) the design so that the real outer dimensions are as specified by you
( e.g. the outer length of the folded box is equal to the value of L,
and Lss
equals to L+d
to allow for the "lost" area of the two side flaps, which, when
folded at 90o, "eat away"
d/2
each ).
To change the expression
of DT, click in the Expression
column field of DT in the Parameters tabular
pane tab and select the desired option from the list.
