NOTE
The exact adjustment is carried out with the aid of the belt tension measuring device.
●
Bring the empty tape cutting unit into a stable position, and then position the belt tension measuring device
at the empty tape cutting unit corresponding to the measurement point in Fig. 7.6.4.
●
Measure the belt tension when the carriage is on the left and when it is on the right:
–
Halfway along the belt you must measure 40 - 45Hz.
●
If necessary, correct the toothed belt tension by moving the corresponding tension piece.
●
Finally make sure that the screws are firmly tightened up at the tension pieces.
●
If applicable, go straight on to check the endless toothed belt (see next section).
●
Fit the empty tape cutting unit into the machine as described in section 7.6.6, subsection "Reinstalling and
adjusting the empty tape cutting unit",.
●
Carry out the "Concluding work" including a function check (see section 7.6.15 on page 7 - 55).
7.6.11 Checking, Replacing and Tensioning the Endless Toothed Belt
If the endless toothed belt is damaged or incorrectly tensioned, this can - similarly to the cut toothed belt - be
the cause of the motor being switched out, premature wear or tapes not being cut.
●
To remove the empty tape cutting unit follow precisely the same procedure as for the cut toothed belt
described above, from the first point.
●
Undo the screws fastening the clamping connector to the cutter wheel carriage (2 socket-head cap screws
M4, see Fig. 7.6.5.) and lift the defective cut toothed belt upwards and off the synchronizing disks.
●
Fit the new endless toothed belt: A, B, C in Fig. 7.6.5. Make sure that the welded join of the toothed belt is
positioned centrally in the clamping connection.
●
Bring the empty tape cutting unit into a stable position, and move the cutter wheel carriage to its left end
position.
●
Measure the belt tension in the middle of the toothed belt using the belt tension measuring device:
–
The toothed belt tension must amount to 30 - 35Hz.
●
If this is not the case, correct the position of the lefthand synchronizing disk axle within the slot accordingly.
To do this, slacken off the hexagonal nuts at the lower end of the axle (underside of the support).
●
Finally, make sure that the synchronizing disks mounting is firmly seated.
●
Fit the empty tape cutting unit back into the machine as described in section 7.6.6, subsection "Reinstalling
and adjusting the empty tape cutting unit".
●
After this carry out the "Concluding work" including checking functioning (see section 7.6.15 on
page 7 - 55).
