10.7.2.3 One or two movable surfaces

One or two parallel work surfaces or a round surface is used. The movements are
lateral (side movement), towards and backwards, sliding/shuttle system (moving bi-
directionally forwards and backwards and also up and down changing each other; see
Fig. 10.12B), and rotational. The sizes of the work surface are 75 × 130, 60 × 130,
150 × 150, and 100 × 130 cm. The machines can work with finished flat-laid or folded
garments. Work surface can be moved manually or in automated way (movement
speed is adjustable). Rolled fabrics can be processed adding two rolling devices that
move the fabric automatically. The machines are used for sample making and just-in-
time, low-, and medium-volume production.

10.7.2.4 One or two conveyor belts
A narrow belt is used to place one garment, a wide conveyor belt is used to place more
than one garment next to each other, or two narrow belts are used to place two garments
(in this case can be processed with two different images) (see Fig. 10.12C and D). The
sizes of work surface are 60 × 60, 80 × 80, 90 × 90, 120 × 120, 125 × 125, 60 × 130, and
80 × 160 cm. The machines equipped with one or two conveyer belts are the most pro-
ductive and used for medium- and high-volume production.

10.7.2.5 Mannequin

Three-dimensional treatments are performed by help of one or two mannequins fixed
in horizontal or vertical position. The movements are lateral, forwards and back-
wards, and rotational. The sizes of the work area are 120 × 120 cm and 150 × 150 cm.
Machines can have dual engraving system to treat both symmetrical parts of the gar-
ment simultaneously.

10.7.2.6 Static or movable surface + mannequin
Mannequin for three-dimensional highly productive processing jeans and flat two-
dimensional surface is used to process denim goods on a horizontal surface.

10.7.2.7 Conveyor belt + fabric feeding devices
Two rolling devices in front and at the end of the conveyor belt can ensure continuous
processing of rolled fabrics.

10.8 Embroidery laser finishing

In the 1990s of the 20th century, laser treatment started to replace traditional embroi-
dering methods. Since that time, technologies have changed, and laser equipment has
significantly improved. In performing fabric embroideries, the laser through cutting
and kiss cutting are used the most often.
