Magnetic tapes stacking inside the cartridge and their extraction
Correct the defects of MT strips or replace the damaged strips during the routine
inspection of accessories.
If the marginal areas of the tape (20–30 mm from the strip ends) have transverse bends with
curvature radius less than 20 mm (Figure 7a), they have to be straightened to an acceptable
condition . Densely roll the tape in the inverse curvature or slightly stretch it on an angular
edge (for example, on the table’s edge) to get it straightened . The same is applied to the bent
MT strip corners (Figure 7b) . In case the tapes’ edges are failing to straighten up, cut them by
the cutter from SPRK .
Another kind of MT eliminated defect (Figure 7c) is MT surface pollution (polluted films,
water, solvents, chemical solutions, dust particles, rust, metal, etc .) . MT surface should be
cleaned with alcohol using a special container from SPRK (Figure 7d) .
MT with considerable bends (breaks) (Figure 7e), breaks of edges (Figure 7f) and punctures
cannot be mended . Such tapes should not be used in case the fault area cannot be removed
with the SPRK cutter .
Cut plastic MT using paper scissors . When cutting, it is recommended to trim MT edges so
that they are rounded in shape .
Cut paper cartridges for ½’’ plastic MT from printed stencils using paper scissors . Cut along
the lines .
MT pieces stacking inside the cartridge is carried out as follows . The stacked MT piece
should be rolled into a roll of ≈ Ø20 mm (for example, it can be rolled on your finger as shown
in Figure 6а), then pushed inside the cartridge (Figure 6b) . Each subsequent roll is stacked
inside the previous one .
MT pieces extraction from the cartridge is carried out as follows . Turn a roll of MT pieces
inside the cartridge that the butt end of the upper whorl of the tape would appear opposite
to the cut of the cartridge (Figure 6c) . Then, pull MT strip by its edge in the tangent direction
towards the cartridge circumference (Figure 6d) .
