Jakob Müller NH2 53, for light to medium-weght elastic and non-elastic narrow fabrics with unlimited repeat lenghts.
Jakob Müller NH2 53 Concept
The new Jakob Müller NH2 53 (various patents registered) employs components that have been in successful use for many years in tandem with innovations, which are set to play a pioneering role in textile machinery design.
As a result of a new type of drive system, the machine has a very low energy consumption. The electronic control of the frames, powered by linear motors, permits unlimited repeat lengths. Both the weft and auxiliary thread transports are electronically controlled and infinitely adjustable. The fabric take-off and the main motor also utilise this drive concept.
Important features
- Compact design
- Very high levels of user-friendliness
- Low energy consumption (less than 1 kW)
- Unlimited repeat lengths due to electronic frame control
- Very quick changes of pattern possible, no re- quirement for the preparation and use of pattern chains or pattern drums with cam discs
- Positive-controlled electronic thread transport with infinitely adjustable setting
- Electronically controlled fabric take-off
- Electronically controlled main drive for infinitely adjustable weaving speeds
- Electronically controlled creep speed
- Precision fabric take-off with non-slip draught and pressure roller coverings for weave protection
- Minimal maintenance requirement
- Low spare part requirement due to limited number of mechanical components
- Minimal lubrication oil consumption
- Optional execution for 1 needle or 2 needle Z- system for H-M-T
Machine controls
The machine controls consist of two components:
- A unit attached to the machine, the operation of which is limited to the functions needed for weav- ing.
- A portable programming device with wireless data transfer to machine for programming. All relevant data and parameters such as narrow fabric design, speed, weft density, but also downtimes etc. are stored. They can be recalled for statistic analyses at any time. Several machines of this type can be programmed via a cable-free link using only one control device.
This clear separation considerably reduces the bur- dens on the weaving personnel.
Machine drives
The main motor, a brushless servo-motor, is positioned directly on the main shaft, which removes the need for intermediate gears and belts. The control print is mounted directly on the motor. This drive concept permits precisely controlled operation with a minimum energy requirement.
Patterning
The frames, powered by linear motors, allow unlim- ited repeat lengths. Mechanical components such as cam plates or pattern chains are unnecessary and the costs of purchasing, storage and wear- related replacements are saved. Moreover, pattern changes can be completed in a very short time in an uncomplicated manner.
A new pattern is communicated to the machine directly by means of remote control. On the machine type NH2 53 2/130 transfer is also possible via LAN-. The pattern can either be designed using MÜCAD MINI / MICRO / NANO programming software or directly by means of the remote controls.
Weft and auxiliary threads
The weft and binder threads are driven by separate step motors and thus infinitely adjustable in line with the thread requirement. During a change of pattern, the parameters for weft and auxiliary feeding can be transferred to the machine automatically, thus removing the need for separate setting. The fabric take-off rollers are also powered by a step motor. This permits infinite variations in weft density of 8 –60 threads/cm.
Cone storage of the weft and auxiliary threads
The weft and auxiliary threads are fed from a free standing cone store (Type F) positioned next to the machine. As an option, a cone frame (Type N and Z) can be installed above the machine.
