MANUAL SYSTEM INSTALLATION
A Marker is made by placing pattern after pattern into the marker
space. This space defines the fabric that will be utilized in the lay. The
space is defined by the following components which are common to all markers.
Fig 1: Manual system installation for Marker making.
1. The two Selvedge Lines are drawn parallel
to the edge of the cutting table. The distance between the selvedges denotes
the minimum usable width of the fabric. If the fabric were 60 inches wide, the
width between the selvedge lines would (usually) be no wider that 59 inches.
2. The Beginning Line is at the left end of
the marker as seen by the marker maker/spreader. This line is perpendicular to
the selvedge and denotes the beginning point of the marker. Usually 18 to 24
inches of paper are left at the left end before the marker to accommodate the
legend.
3. The End Line is placed at the end of the
marker (opposite the Beginning Line). This line is drawn across the width of
the marker and is located after the extent of the last pattern. Additional
length may be added to the end to accommodate the fabric allowance for end
cutting or the use of catchers.
4. Splice marks are placed along the control selvedge
(closest to the spreader). These Facilitate the overlapping of fabric needed
when a roll of fabric runs out, or when damage in the fabric must be
eliminated.
5. The legend is used to provide the critical
information about the marker. Usually placed at the beginning (and often the
end) of the marker, the legend contains the reference information about the
marker. Prior to spreading, it is critical for the spreader to check the legend
against the cutting order to ensure that the correct style number, fabric type,
width, and ratio for the order is about to be spread.
6. Placement Rules. When the patterns are
placed, the marker maker will follow several rules. First, the patterns are
oriented so the grain line on the pattern is parallel to the selvedge line. The
patterns will be oriented with the nap direction as specified by the marker
mode. The patterns will be interlocked as efficiently as possible in order to
waste the least amount of fabric. The patterns will be placed from largest to
smallest, as this is the most efficient way to create a marker, causing the
least amount of pattern manipulation as necessary. Small patterns are placed
whenever possible in the spaces Between the larger patterns. The cutting method
is considered when interlocking patterns to prevent “impossible” cutting
situations.
