GENERAL INFORMATION 

1. GENERAL INFORMATION 

Description 

HD X2 is a Weft Feeder for heavy duty applications with yarn separation and 

mechanical sensors. It is normally used with very dusty yarns where optical sensors 

cannot be applied. It is basically recommended to weave polypropylene, but is also possible 

to weave other types of particularly thick yarns, where a high motor power is required. 

The following models are available: 

HD X2 with Funnel and Piezo input sensor (P/N 56F510) 

With anti balloon funnel (included). 

HD X2 with FLEX/BRUSH and Piezo input sensor (P/N 56F511) 

It can be fitted with bristle and Flex brakes (not included). 

HD X2 with Funnel and Piezo input sensor for roving (P/N 56F514) 

For applications with fiber glass roving. 

Characteristics 

 

 

 

 

 

 

 

 

The Weft Feeder can be set for S or Z winding directions depending on the yarn twist. 

Yarn separation adjustable up to 4,5 mm. 

Weft breakage control ("Loom Stop" function) through the TFE4 Weft Stop Motion 

piezo input sensor. 

Max speed can be selected through a four position switch. 

Overload and lock of the motor 

In both cases the motor stops and the relevant alarm is given by the signalling LED. 

Winding speed of the yarn on the Spool body 

The speed is automatically calculated and self adjusted according to the speed of the 

loom. 

Weft reserve 

The weft control is carried out by means of two mechanical sensors placed on the fi xed 

part of the Spool body.

CONTROL ELEMENTS 

2. CONTROL ELEMENTS 

Weft Feeder On/Off Switch 

Warning! 

The Weft Feeder On/Off switch, DOES NOT cut-off the main power supply (see fig. 5). 

fig. 5a 

Maximum Speed Switch 

To set the maximum speed rotate the switch to the appropriate position. 

500 m/min 800 m/min 1200 m/min 1600 m/min 

2-1 - HD X2 Ed. 0546 

fig. 5b 

Note: 

Normally the switch should be left to position 1600 m/min (fig.5b), since the feeder automatically 

calculates the speed according to yarn consumption. However, with very low speeds 

or wide looms, it could be helpful to reduce the maximum speed in order to avoid 

unnecessary acceleration.

VOLTAGE SUPPLY BOX 

3. VOLTAGE SUPPLY BOX 

The HD X2 feeder is compatible with the X2 stand-alone Voltage Supply Boxes. 

Note: 

For special applications, like multiple insertions of two or more yarns together, a Heavy Duty 

Voltage supply box, suitable for higher power consumption, is available (p/n 56C570). 

IMPORTANT! 

Please refer to the label sticked inside the Voltage Supply Box for the correct wiring according 

to the main power supply. 

• The interface board for the “Loom Stop” or “Automatic Package Switching” 

function, is integrated. 

3-1 - HD X2 Ed. 0546

INSTALLATION AND CONNECTION 

4. INSTALLATION AND CONNECTION 

Voltage Supply Box and Weft Feeder installation on the 

Stand 

1. Take the Voltage Supply Box out from the packing. Open the cover and connect the 

three-phase power cord (4-wires cable). Make sure that the earth connection is properly 

made (see fig. 6). The section of each wire cannot be less than 1.5 mm 2 . 

Warning! 

Such operation must be carried out BEFORE powering the unit. 

2. Fix the Voltage Supply Box to the Stand by means of the proper brackets 

(see fi g. 7 ). 

Note: 

Minimum distance from the Box to the floor must be 20 cm. 

3. Fix the Weft Feeders on the Stand by means of the existing clamps ensuring that the 

screws and locking nuts are correctly tightened. 

Notes: 

a. It is recommended to mount the Weft Feeders in horizontal position, in order to avoid 

coils falling into the funnel when the loom is stopped. 

b. Do not install the Weft Feeder directly on the loom structure: mechanical 

vibration may damage or interfere with the correct functioning of the unit. 

A complete line of Stands and Creels is available upon request to 

Nuova ROJ Electrotex Srl. 

c. Verify that the Weft Feeder Stand is electrically connected to ground. 

4. Place the Creel behind the Feeders' Stand avoiding sharp angles to the yarn path from 

the Creel output to the Feeders.

FUNCTIONING AND SETTING 

5. FUNCTIONING AND SETTING 

Manual threading 

1. Switch off the Weft Feeder. 

2. Insert the threader into the Weft Feeder entry hole and push it: the threader 

follows a guided path and comes out from the Winding disc eyelet. 

3. Hook the yarn to the threader slot (on the input side), and pull it (see fig. 14). 

4. Insert the Threader between the Spool body and the Sensor-holder ring up to the 

output of the funnel: in this way the Weft Feeder is fully threaded (see fig. 15). 

Important! 

Never pull the threader or the yarn backwards as it could damage the unit. In case of threading 

errors or if the yarn breaks, repeat the operation from the beginning. 

5. Switch On the Weft Feeder: the reserve is fully restored (the Signalling led will 

turn Off).

Motor rotation direction and coil's pitch 

The motor rotation direction must be selected 

according to the yarn twist. 

Note 

In case of non-twisted yarns (flat yarn, monofilament, 

etc.), check the unwinding direction 

of the coil from the package and set the motor 

rotation to the opposite direction. 

Proceed as follows: 

fig.16 

1. Switch Off the Weft Feeder 

2. Set the direction of rotation (S or Z) with the switch (see fi g 19). 

3. Grip the winding disc and, whilst pressing the orange button on the front of the spool 

body, rotate the disc until the button is felt to locate. 

4. Keep the orange button pressed in and rotate the winding disc in the appropriate direction 

(the same as the rotation switch selection, see point 2). The Separation increases 

from 0 to 4 mm the more the disk is rotated (see fi g. 18).

Mechanical sensors 


The weft control is carried out by two sensors (A and B) placed on the fixed part of the Spool 

body (see fig. 20). 

Note: 

If the Weft Feeder does not operate correctly without showing any alarm on the led, please 

follow the “Automatic setting of mechanical sensors” procedure. 

Automatic setting of mechanical sensors 

Before starting the operation, check the following: 

• The Spool body has not been turned (the sensors must be positioned as in 

picture 20). 

• The Sensors have not been damaged or blocked; 

• The Sensors-holder ring and the Spool body has equal distance in all directions to the 

Spool body. 

Then, proceed as follows: 

1. Switch the Weft Feeder OFF. 

2. Disable the TFE4 moving the switch to the DIS position (see fig. 21). 

3. Switch the Weft Feeder On and let it turn without weft until the winding disk stops. (Led 

= fi xed ON). 

4. Switch the Weft Feeder Off and enable the TFE4. 

At this point the feeder is ready for yarn threading.

MAINTAINANCE AND TROUBLESHOOTING 

6. MAINTENANCE AND TROUBLESHOOTING 

Maintenance 

• It is recommended to periodically clean the lint or dust accumulated on the Weft Feeder 

and on the Voltage Supply Box, by using a low pressure compressed air jet. 

Note 

Before blowing the dust off, it is necessary to remove the yarn from the Spool body, in 

order to avoid that the air jet blows the weft inside the Winding disc. 

• The Weft feeder does not need extra lubrication.
