Systems and methods for severing elongated material include a rotatable
first roll having a first severing structure, a rotatable second roll
having a second severing structure corresponding with the first severing
structure for severing a length of the filament positioned between the
rolls, a drive system operable to independently rotate the first roll and
the second roll according to a drive command, a sensor system operable to
make measurements and generate actual position signals representative of
an actual current rotational position of the first roll and an actual
current rotational position of the second roll, and a control system for
receiving the position signals and operable to generate the drive command
in accordance with predetermined control parameters and based on the
actual rotational position signals, wherein the drive command synchronizes
the respective rotational positioning of the first roll and the second
roll.
