Glossary 285

Face down single direction spreading mode all fabric plies are spread with their face side
down only in one direction. After laying a ply, it is cut off from the fabric roll across its width.
Face to face both directions (zig-zag) spreading mode the fabric is spread in both directions.
At the end of every ply, the fabric is folded, and spreading continues in the opposite direc-
tion. So, the first ply has its face side up, the second ply face side down and the third ply
again face side up.
Face to face single direction spreading mode the first fabric ply is spread with its face side
up. After laying the ply, it is cut off from the fabric roll across its width. After/during the
‘dead heading’, the fabric roll is turned for 180 degrees, and the next ply is spread in the same
direction only with its face side down.
Face up both directions spreading mode all fabric plies are spread with their face side up in
both directions. After laying a ply, it is cut off from the fabric roll across its width.
Face up single direction spreading mode all fabric plies are spread with their face side up and
only in one. After laying a ply, it is cut off from the fabric roll across its width.
Fiducial marks (registration marks) marks located in the corners, edge centres, or both of a
printed image to ensure pattern alignment by a vision system of the automated cutter.
Fine cutting of components the work operation of manual cutting process when components
are precisely cut out along their original contours.
Final operations work operations in a cutting room that end the cutting process and prepare
the cut components for their further processing in sewing lines. There are quality control of
cut components, recutting of faulty components, and numbering, sorting, and bundling of
cut components.
Fully automatic lay end cutter a cutter that performs automatic cutting of a fabric ply, returns
to its original position, automatically counts each cut fabric ply, and ensures automatic lift-
ing and lowering of a front rail (see lay end cutter).
Fully automated spreading process the spreading process using a spreading machine, when
the operator sets only all necessary parameters (length of the lay, spreading speed, and fabric
tension) and does not take part in the spreading process. It can be used for high-quality easy-
spread materials.
Fusing a process during which cut components or their blocs are fused with interlinings coated
with thermoplastic resin. Fusing of certain garment components is performed to create
strength and stability of the garment, improve its shape, and increase resistance.
Fusing resins polymers applied to fabrics intended for fusible interlinings, which melt under
the application of heat.
G
Galvanometer (galvo) laser systems the laser beam is delivered by rotating mirror. Galvanometers
are motors which move the mirrors and with it direct the laser beam in different directions.
Gantry (crossbar, beam, and cutting bridge) a structure that strands across the Y-axis of a
machine and carries the tool system. The word gantry comes from the support platform that
holds the cranes.
Gantry cutting system a cutting device is fixed on the gantry moving along a set of tracks.
The cutting device is powered by several servo motors which move the laser cutting head.

I
Initial marker a marker in which pattern pieces are placed in a logical way with allowances
around them to achieve required precise pattern matching of the components later directly
on the fabric.
