Appalachian Electronic Instruments is a company that produces and develops detection systems specific for the tufting industry.
With their tight-end detection system and their yarn break stop motion system Appalachian has become world wide market leader.
The Tuftight LX has the same detection principle as the industry proven original tuftight, reconfigured in a simpler more integrated and easier to maintain design. Instead of movable switches, the sensitivity is now adjusted by moving the lower bar with a unique rack and pinion mechanical adjustment to set the angle of the yarn contacting the switches. Once this mechanical adjustment is made, the fine sensitivity is set with a programmable stop delay, selectable for the entire rail or for each meter section. This ability to set the sensitivity for each one meter switch section accommodates various creel and header lay-outs by normalizing the tight end response across the machine. Also included is a PLC interface using an Industry Standard RS-232 serial port, which allows connection of the LX to plant data systems.
TUFTIGHT LX Features & Capabilities:
- Indicator lights shows area of tight-end.
- Sensitivity set by easy mechanical adjustments.
- Yarn path capacity up to 7-meters.
- Rack and pinion yarn tension adjustment for matching tension requirements to yarn type (wool to polypropylene).
- User replaceable switch covers.
- Minimal yarn contact with pressure sensitive switch surface
- Removable/Replaceable switch covers by user
- Adjustable time delay per meter section for more precise sensitivity setting.
- Color Touchscreen Interface.
- Light Indicators each meter segment
- Same switch design as original proven AEI Tuftight.
Designed exclusively for the tufting machine TMMS provides very effective yarn break detection performance with all yarn types /sizes and single-sided or dual-sided machine configurations.
TMMS has 12 channel capacity. Generally two or more fiber optic channels are dedicated to each needle bar.
One or more channels are positioned at or between eyebars below the feed roll(s).
Two or more fiber optic channels between the header(s) and top yarn guide is very effective. Saturation coverage provides effective detection and prevents the mend that would otherwise occur.
TMMS Features and Capabilities:
- Up to 12 channel capacity
- Visible-Red fiber optic light channels
- Mounting hardware for optimal channel placement
- Operator touch screen full color user interface
- Menu driven programming
- Very simple, intuitive menus
- Automatic sensitivity set-up via yarn pass-thru light beam
- Bar graph represents channel alignment and sensitivity each channel
- Extremely rugged fiber optic cable and detection heads
- Intelligent electronics with dynamic monitoring of signals
- Integrated auto-adjust gain system (AGC) maintains sensitivity throughout the life of the light source
