 15.14- Needle bar translation
.
Always adjust the needle bar movement on the basis of the selected stitch length. To do so press button stitch length button
(image A) on the upper part of the head and turn the hand wheel.
When button A is pressed down:
- Turning the hand wheel towards the operator (anticlockwise) will increase the translation
- Turning the hand wheel towards the operator (clockwise) will decrease the translation.
Release the button once adjusted.
To verify :
Lift puller
Lift presser foot
Insert a piece of paper and lower presser foot and puller and rotate the hand wheel in order to check whether the needle
perforates the paper perfectly, or, whether it is ripped (elliptic hole).
Adjust the movement length until the hole is perfectly round.
A
WARNING
Never press button A while the machine is in operation.
Before starting up the machine, make sure that button A is released

15.13- Needle bar thread guide adjustment

The needle bar thread guide must be adjusted so that when the needle bar is in lower or upper position the thread guide is in
line with the casting opening.
This thread guide is to shut the stitch and it is possible to adjust it , the higher it is , more closed is the stitch.

 15.15- Looper meeting point
This cam is to move the looper’s in synchrony with the needle, to find the correct meeting point while moving down stroke and
up stroke .

POSITION
In order to position the looper’s start movement cam correctly respect to the needle, place the needle bar at lower dead point.
The cam should be positioned with the second screw in rotation sense facing service hall . Check its position against the two
illustrations below:

CAM

In this way the looper tip passes through the needle hollow side face:
• During forward movement the looper is lower than the centre line of the eye itself
• During backward movement the looper is higher than the centre line of the eye itself

38
VI.BE.MAC. s.p.a.
 15.16- Looper regulation
In order to position the looper correctly respect to the needle, place the needle bar at lower dead point.
Loosen the two screws (image A) that fix the clamp to the shaft and check that the distance between the needle and the looper
tip is 4.5 mm. Tighten the screws at the end of the operation.
Loosen the screws on the looper (C) and the needle guard (B) and turn them slightly to the left (image 2).
Turn the hand wheel by hand and take the looper tip to the centre of the needle.
Check that the looper tip touches the needle without deflecting it (image 3), then tighten the screw (C).
Bring the needle guard against the needle and make the needle bend a little(image4) The distance between the looper and
needle is 0.05 mm.
Check the distances between the various mechanical parts as illustrated in the figure below: 4.5mm

 15.17- Spreader phase
This cam (image A) is to adjust the spreader in synchrony with the needle and looper movement.

POSITION
In order to position the spreader start movement cam correctly, place the needle bar at the following phase point (image B).
Turn the hand wheel until the thread exit hole on the upper part of the looper crosses through the eye of the needle, with the
needle bar in going down.

A B

At this point, the cam’s fixing screws are in the following positions: one screw in vertical position and the second perfectly hori-
zontal, as illustrated in the figure below:

15.18- Spreader height

When the looper is as far forward as it will go, the distance between spreader pin and the back of the looper should be 0.5mm
(image A)
Under the spreader must be applied the 2 spacers (image B)

0,5mm

VI.BE.MAC. s.p.a.
 15.19- Movement length

The movement of the pin that moves the spreader must be divided equally respect to the shaft .(image 1/2)and it can be
adjusted from the lower regulation screw
In order to make the loop spreader movement as wide as possible,the Positioning of the cam respect to the transverse shaft
determines the total movement of the spreader. There should be a gap of 6 mm between the left-hand side of the cam and the
transverse Shaft.(image 3)
The correct spreader stroke must be that when it’s all to the left the pin is slightly over the looper edge (image 4) and moves as
much as possible to the right side, to open the triangle without touching the other looper (image 5) .

 15.21- Spreader play regulation
If the spreader has some play left or right , it’s possible to adjust it :
Loosen the 2 grab screws (image 1 )
Tighten the ring so that the movement of the eccentric is free and there is the least play possible .

15.20- Spreader pin position

The end of the pins should be bent slightly to the right (2 mm) in order to prevent the thread from slipping.

 15.22- Motor regulation
1. Fix the first screw of the coupling in rotation sense, in the motor shaft grove (image 1)
2. Tighten the second one , leaving the screws of the sewing machine shaft loose
3. Turn on the unit, at this point the motor will do a complete rotation
4. Back pedal so it will position in needle high position
5. Position the 0 on the hand wheel in correspondence with the screw (image 2)
6. Tighten the screw on the sewing head shaft (image 3)

VI.BE.MAC. s.p.a.
 15.23- Puller regulation
The puller device can be regulated to the right or left to obtain more or less curve on the waist band and rotated in case of a very
curved waist band .

To adjust the puller right or left loosen the 2 screws (image 1) and move the puller to the desired position and tight again the
screws

To rotate the puller loosen the screws as (image 2) and rotate the puller as desired and tighten once adjusted
