Seaming Chuck:
The Seaming chuck has a threaded holder and simply needs to be screwed on. Please
note that it is an opposite thread and is tightened in the same direction of rotation as
the seaming head. The Seaming Chuck is made specifically for a Can Size and Lid
Type. The tolerances of the Lid must be within 0.05mm to the original size against
which the chuck is supplied.
Seaming Roller Settings:
The machine has 4 Rollers. 2 x 1
st
operation rollers and 2 x 2
nd
operation rollers. 1
st
operation rollers (thinner grooves) are mounted on arms no. 1 & 3 (opposite each
other) whereas 2
nd
operation rollers (larger grooves) are mounted on arms no. 2 & 4
(opposite each other). A double Cam controls the movement of the Rollers. The top
part of the Cam for the 1
st
operation and bottom for the 2
nd
operation.
During Seaming, the drive to the Cam is given by engaging the Clutch. The 1
st
operation rollers are brought in gradually for about 4.5 rotations and then rapidly
retracted. These form the Hook in the Seam.
The 2
nd
operation rollers are then brought in for about 1 rotation to press the Hook into
forming the Final Seam after which the clutch disengages.
The quality of the seam depends mainly on the Seaming rollers and their setting.
Please carry out the settings as described below. Also refer to the Video guide provided
for setting the Rollers.
1. Pressure Setting:
To adjust the pressure of the rollers, the seaming arm/lever (SA-49) must be moved
inwards or outwards. To do so, loosen the bolts on the Cam Follower Lever (SAV-40) of
the corresponding lever. Then move the Seaming arms inwards/outwards to achieve
the desired setting. Once the setting is done these should be locked in place and the
bolts tightened completely.
The pressure is set at the maximum inward travel of the rollers. The maximum travel is
the highest point on the Seaming Cam corresponding to that lever.
First move the levers out. Now engage the clutch and manually rotate / inch the head
for ~4.5 rotations. This is the position where the bearings mounted on the Cam
Follower Levers (1st operation) are at the top most position and the seaming pressure
is maximum.
At this point adjust the 1st operation rollers by moving them inwards till the gap
between the lip of the seaming chuck and roller groove is as per the attached drawing.
Fully tighten the bolts on the corresponding Cam Follower Levers.
