Abstract

During the manufacturing process, one end of the type band is rotated through 180 degrees, then connected to the other end. This band will have only one surface. With a normal type band, a certain character is at a certain position after one revolution of the band. With the Moebius type band, a certain character will only be back at the same position, after two revolutions of the band. This will allow additional character types and will give higher performance. The print band rotates around two pulleys. The print band, on the hammer side, will look like the normal band used now. On the opposite side, the Moebius type band will make the 180 degrees turn. The two pulleys will have grooves for the characters.

Printer Steel Band, Made Like a Moebius Strip

      During the manufacturing process, one end of the type band is
rotated through 180 degrees, then connected to the other end.  This
band will have only one surface.  With a normal type band, a certain
character is at a certain position after one revolution of the band.
With the Moebius type band, a certain character will only be back at
the same position, after two revolutions of the band.  This will
allow additional  character types and will give higher performance.
The print band rotates around two pulleys.  The print band, on the
hammer side, will look like the normal band used now.  On the
opposite side, the Moebius  type band will make the 180 degrees turn.
The two pulleys will have grooves for the characters.

      The current printers can easily be converted.  To the
microcode, the Moebius type band will appear to be twice as long as
the normal type band.  In addition to this microcode change, only
some timing synchronization values may need to be updated.  With new
printer designs, the characters on the print band may be
off-centered.
