Prevention
of inclusion of foreign matter
Sewing
threads and crepe tape are not used.
No thread fuzz is generated and inclusion of foreign matter is
prevented.
Prevention
of paper dust and thread fuzz
Paper
dust and thread fuzz are not included in the bag because the bag is
trimmed after sealing the inner PE tube (for units with a sealer).
Cost
reduction and enhanced productivity
Threads
and crepe tape are not required.
Cost of auxiliary materials is reduced and replacements are
decreased to enhance productivity.
Separation
of inner tube
For
bags with inner PE tubes, the score cutter (option) separates the
inner PE tube from the outer kraft paper bag with ease.
Improved
working environment
Machine
noise is very low because no sewer is used.
The working environment is improved and maintenance is easy.
More
accurate temperature control
A
temperature controller is provided for each pair of heaters.
Heater break interlock and abnormal temperature alarm are
provided.
To control heaters, noncontact switches (SSR) are used in place
of ordinary magnetic switches to effect a high-accuracy temperature
control.
