Ironer belts
For tensioning the ironer belts, see page 39.
Using the machine will pollute the ironing belts so that they will become smaller, longer and thinner. If the ironing effect has become unacceptable, you have to exchange the ironing belts by new ones.
Slacken the belt tensioners by reducing the spring tension of the tensioners to zero and remove the tension nut of the springs so that the tensioner can move freely.
Do this on the left and right side of the machine (see page 39).
Push (inside the side frame, on both sides) by means of a beam (or some other tool) the tensioner to its highest possible position. Place the small beams vertically underneath the spanner.
Now remove the top plating, the rear plating as well as the vapour exhaust beam (see page 39) of the machine.
The pressure roll of the ironer (roll straight above the ironing roller) has to be lifted up. This can be done by putting wooden beams from the feeding side between the main roll and the shaft of the pressure roll on both sides (left and right). The beams can be used as a lever for lifting the roller.
Mounting new ironing belts happens in reverse order. For this purpose, please note the following points:
-The flap on the ironing belts has to be on one side of the ironing roller. Also the ironing belt has to be placed in such a way that the flap is dragged by the ironing belt.
-Connect the ends of the ironing belt in such a way that the ends are in line. This means that the pulled part of the belts may not protrude on a side. This could cause a mechanical load to the machine, which does not help its life of the machine.
Drive
The chain tension has to be checked biannually as described on page 38.
The condition of the chain wheels has to be checked biannually, as well. If the chain wheels are worn down, they have to be exchanged.
Slacken the chain by placing the motor in its top position. Loosen the hexagon socket screw of the chain wheel that has to be exchanged one turn and remove the chain.
Important
The tightening moment of the taper lock bolts for the clamping bush has to be 31Nm to prevent slipping.
