Glossary 287

Multitool cutting head a set of cutting devices to perform cutting by an automated cutting
system. It may contain two to five different tools – knives, creasing and scoring tools, notch
tools, drill punches, and markers. The choice of each tool for the cutting process depends
on the cut material, the configuration of cut lines, and the cutting operations to be realized.

N
Nap prominent direction in which surface fibres on a fabric lay.
Nesting software a specialized software that allows the operator to move pattern pieces on a
computer screen and position them in the area whose width corresponds to the width of the
cut material.
Notch cutting tool used for cutting easy and precisely alignment notches.
Notches shortcuts athwart the edge of components that help to join components in the right and
precise way during sewing process.
Numbering of cut components one of the final operations in a cutting room during which ev-
ery component gets its sequential number. It corresponds to the number of a fabric ply from
which the component was previously cut. In further sewing process, the components with
one sequence number are joined in one article.

O
Off-load screen a PC screen placed in the take-off zone of the cutter on which the full marker
or only the part of the marker already cut is seen to identify cut components.
Operator stand panel a special platform to allow the operator to ride alongside the table
during spreading process. It can be equipped with adjustable seat.
Oscillating (reciprocating) knife oscillation is a motion that repeats with a constant period.
Reciprocating motion includes the restriction that the motion is linear. This way, knives per-
forming up and down motion in a single-ply cutter should be called oscillating, but knives
in a multi-ply cutter where the vertical motion of the knife has to be more precise/restricted
should be called reciprocating. Although there is a difference in meanings of these two terms
(unfortunately not very clearly stated) knives moving up and down in regular rhythm per-
forming both single- and multi-ply cutting process are most often called oscillating knives.
Oscillation a motion that repeats with a constant period.
Overall marker a marker in which all pattern pieces of one or more garments are positioned in
a free arrangement to obtain minimal fabric utilization.
Overcut of the knife the distance between the point of entry of the cutting edge into the mate-
rial in the direction of travel and the last point of contact between the edge of the blade and
the material.

P
Pattern design or style of a printed, woven, or knitted fabric, for example, striped, checked,
floral.
Pause/stop buttons used to make a pause during the work process to clear material, make ad-
justments, inspect work, etc. Pausing the machine stops any motion while the servo motors
are powered and maintain position.
Pile the raised surface of a fabric. It can be either cut or looped, patterned or plain, or textured
or flat.
Pile height the height of pile yarn above the backing.
Pin table a table with grid of holes in their surface in which the pins can be fixed in the needed
height and placed in accordance with the fabric pattern and the marker qualities.
