Overview
ULTRAFEEDER - 1.3 -
Advantages obtained by using the ULTRAFEEDER devices
ƒ
Constant yarn tension both when the machine speed changes and when the yarn
packages gradually get empty.
ƒ
Best efficiency by eliminating the yarn breakage (tears and extratensions), and
possibility to work at the highest speed offered by the machine.
ƒ Possibility to work with a wide range of yarn types including:
-
Very thin yarns, such as bare elastomers 11/17 DTEX.
- Very difficult yarns, such as covered elastomers
- Elasticized yarns either bare or covered
- Nylon, cotton, etc.
ƒ Yarn tension graduation capability, with 0.1 g. resolution (INC/DEC function - BTSR
Patent).
ƒ Finished product quality optimization thanks to the Master/Slave operating mode
(
BTSR patent )
ƒ Accurate yarn feeding speed measurement (1 to 1500 m/min) – (LFA m/min = Length
of Absorbed Yarn).
ƒ Optimization of yarn consumption and less difficulties to keep the correct size of
manufactured products.
ƒ
Drastic reduction of yarn consumption (8% to 15% for bare elastomers, 2% - 5% for
covered elastomers).
ƒ
Better quality of manufactured product (defect free) and drastic drop of second choice
production.
ƒ Constant keeping of set size, independently of the yarn package emptying condition.
ƒ Possibility to use the yarn up to the complete package emptying.
ƒ Better machine efficiency.
ƒ Possibility to feed the strap elastic or wrist band, guaranteeing a constant compression
(hosiery machines).
ƒ Possibility to perform gradual compression with no limits, and with a minimum
resolution of 0.1 grams.
ƒ Efficiency optimization on machines that use the yarn in non-continuous mode (Start-
Stop), thanks to the possibility to draw back immediately the yarn fed in excess
(“reverse" applications) .
ƒ Full control of yarn presence, even during the “LEARN” phase performed with the
SMART MATRIX FEEDER/PFU control terminal
(“reverse" applications) .
ƒ Possibility to find the best application conditions of ULTRAFEEDER device: (No of
coils to be wound around the roller, ideal programming values for parameters etc),
thanks to the continuous visualization, in graphic form, of both average and peak
values of yarn tension.
