Machine capabilities vary widely. Some machines only support single-sequin devices. These may be mounted on the first or last needle, or sometimes both. Some machines support twin-sequin devices. These too can be mounted on first and last needles. Newer machines can support multi-sequin devices. These may perform consecutive sequin feeds – one at a time whilst stitching. Some may allow ‘stack feeding’, where multiple sequins are dropped and secured with a single fixing stitch.
In summary, the main sequin device configurations include...
Machines supporting one sequin per device. These feed only one sequin at a time.
Machines supporting one or two devices per machine head, usually on first or last needles.
Machines supporting twin-sequin devices with no stack feeding – e.g. Barudan FDR-II Twin Sequin, Tajima TBF, SWF Twin Sequin.
Machines supporting twin-sequin devices or even double twin-sequin devices with stack feeding – e.g. Dahao.
Machines supporting multiple sequins per device – four, six, eight, and possibly more sequins – with or without stack feeding.
Note: An increasing number of machines support multiple decoration types including sequins in combination with chenille, beading, cording, and others.
Single and twin configurations still represent the most common type used in sequin production. Even then, different configurations and design types are possible:
Configuration |
Design type |
Single-sequin device on one needle |
The simplest configuration possible, this allows you to produce designs incorporating single-sequin fills, runs, and individual sequin drops. |
Single-sequin device on two needles |
Usually mounted on first and last needles, this setup allows you to incorporate two types of single-sequin fills, runs, and sequin drops. |
Twin-sequin device on one needle |
This configuration allows you to incorporate twin-sequin runs and fills. Some configurations (Dahao) also allow twin stacking. |
Twin-sequin device on two needles |
This configuration allows you to incorporate two types of twin-sequin runs and fills. Again, some may allow twin stacking. |
Double twin-sequin device on one needle |
This configuration allows you to incorporate two types of twin-sequin or quad-sequin runs and fills, as well as twin or quad stacking. |
Note: The kinds of design work you can do with two single-sequin devices and a single twin-sequin device are different. The twin single-sequin setup will allow you to include runs and fills of either sequin, but not both together in the same run or fill.
