2.5.1 Fire prevention measures
WARNING
Risk of fire due to hot heat cutters
Disregarding the following measures leads to fire risks and therefore risk of injury.
4Installation, setting and operating the WeftMaster CUT-iT Dornier only by
authorized personnel.
4Set running and idle temperatures of cutting wires as low as possible.
4Pay utmost attention when blowing-off and cleaning weaving machines with
WeftMaster CUT-iT Dornier connected.

supervision.
4Do not lay objects on or over the heat cutters.
4Have suitable fire extinguishers available in case of fire.
WARNING
Risk of fire due to short-circuit
Disregarding the following measures leads to fire risks due to short-circuit. Risk of
injury due to fire risks.
4Fit heat cutters offset to each other to separate electroconductive yarns (e.g.
Lurex).
4Only fit the heat cutters with the WeftMaster CUT-iT Dornier switched off.

3 Product and Function
3.1 Product description
The device is used to separate and melt selvedges of fusible textiles (synthetic or hybrid fabrics) on
weaving machines, especially to separate and melt fabric selvedges or to separate fabrics into strips.
The device can be fitted with various heat cutters. Heat cutter selection depends on fabric material
processing, material transport speed as well as filling and warp densities.
3.1.1 Control unit
The control unit controls the electrical current through the cutting wires of the heat cutter fitted on a
weaving machine. The current strength depends on whether the weaving machine is running or idle.

The 4 different current flow modes
Mode Description
Off mode Output current is switched off.
Display: «POWER OFF» (switched off)
Standby mode Time in which the weaving machine is idle. Predefined current flows
through the cutting wires during this time. This achieves an optimum out-
put temperature for the machine to run.
Display: «Standby»
Boost mode Weaving machine starting phase. Predefined current flows through the
cutting wires for a limited time. This current heats the cutting wires as
quickly as possible to operating temperature.
Display: «Boost» (startup current)
Run mode Time in which the weaving machine is running. The predefined current
flows through the cutting wires during this time.
Display: «Run» (running current)
The WeftMaster CUT-iT stops the weaving machine in the following cases
nThe power supply is interrupted.
nA system error is detected.
nNo cutting wire is connected.
nA cutting wire is broken (defective).
nA connection cable is interrupted.
nWeftMaster CUT-iT Dornier restarts.
3.1.2 Heat cutter / cutting wire
1 to 4 heat cutters can be fitted per WeftMaster CUT-iT Dornier control unit at maximum heating output. A
higher number of cutters reduces the performance per cutter.
n6 different cutter specifications
n3 cutting wire types are available in different wire sizes of ø0.5 mm, 0.7 mm, 1.0 mm, 1.2 mm and 1.5
mm. The cutting wire types combined with the strengths can be found in the Spare Parts catalog.
nHeat cutter and cutting wire specification depend on the fabric material and speed, as well as filling
and warp densities.
