The Dubied JET 2 is a semi-automatic electronic V-bed flat knitting machine. It was the first model in the JET series, designed to bring computerized patterning to the factory floor while maintaining the legendary Swiss mechanical durability of the Dubied NH and Dubied MM ancestors.[1]
Electronic Patterning[edit]
The JET 2 replaced mechanical jacquard steel cards with a "magnetic tape" or early disk system for pattern input.
- DUCAD Integration: Patterns were designed on the DUCAD (Dubied Computer Aided Design) station and then transferred to the machine's internal memory.
- Individual Needle Selection: Unlike the manual MM which uses high/low butts, the JET 2 uses electronic solenoids to select needles, allowing for infinite pattern repeats and complex intarsia.
- Stitch Quality: Despite being motorized, it retained the specialized Dubied cam geometry, ensuring the "Swiss" look of the finished fabric remained consistent with their manual machines.[2]
Key Features[edit]
- Motorized Carriage: Unlike the manual MR or MM, the JET 2 is a power machine. The carriage is driven by a chain or belt system, allowing for 24/7 industrial production.
- Four-Color System: Standard with a sophisticated four-color changer that can be programmed to switch yarn automatically within a single row.
- Variable Stroke: The carriage can be programmed to only travel the width of the fabric being knit, significantly increasing production speed for smaller panels.
Technical Specifications[edit]
- Gauge: E-gauge (needles per French inch).
- Bed Length: Typically 200cm or 220cm, allowing for multiple garment panels to be knit side-by-side.
- Memory: Early models used magnetic cassette tapes; later versions were retrofitted with floppy disk drives or early serial connections.
Maintenance[edit]
Maintenance for a JET 2 is significantly more complex than the manual NH:
- Electronic Troubleshooting: Common failure points include the power supply capacitors and the solenoid selection units.
- Sensors: Requires consistent cleaning of the infrared sensors and limit switches, which can be tripped by excessive lint buildup.
- Oil: Requires high-purity industrial oil specifically rated for high-speed electronic machines to avoid "shorting" the selection solenoids.[3]
