2. Principle of operation
The TKBA 21 and 31 consist of two laser emitting
units that attach magnetically to the side of the
driving and driven pulley or sprocket.
The transmitter units emit both a laser line, red for
TKBA 21 and green for TKBA 31, that is projected
onto the opposite unit. On the front of each unit is a
target area with reference lines.

Depending on the laser pattern projected on the
target area, it is possible to determine the type of
misalignment and how to correct it. Belt or sprocket
alignment is easily performed by adjusting the
moveable machine(s) until the laser lines coincide
with the reference lines on both units.
