The Speed Bag HS is ideal for customers needing high speed production.
The Speed Bag "wraps" the product in film that is sealed
transversally on the top and bottom, and longitudinally by forming
the film around the product. After being bagged the product passes
through a shrink tunnel.
The Tunnel is equipped with silicon coated idler rollers which prevent
the film from adhering to the rollers. The product is moved through
the system by a series of chain driven "fingers." The
speed is adjustable, allowing proper product spacing.
Once the product has been wrapped, a corrugated belt continues to
move the product through the system. Adjustments are easily made
to the belt pressure.
After the sealing is completed, the seal bar automatically lifts
and returns to the starting point. The simultaneous wrap and seal
process of the Speed Bag HS is key to achieving high production
speeds. In less sophisticated machinery the wrap and seal processes
are performed separately. Simple adjustments allow for changes in
speed and format.
When wrapping magazines, we suggest fitting the machine with an
automatic feeder designed specifically for that purpose. This sophisticated
machinery operates using a vacuum pump fitted with safety devices.
The safety devices automatically stop the machine when more than
one magazine is picked up by the vacuum pump. Mailing labels are
applied with the addition of a second feeder. The two feeders are
identical, differing only in their timing.
When packaging books, CD's, videocassettes or thick, rigid magazines,
a parallel front feeder is used to automatically load the machine.
The operation of the front feeder is very simple - conveyor "fingers"
pick the product up from a pile and move it to the machine.
On the Speed Bag HS you can install two feeders. For the standard
conveyor, additional feeders and extended in-feed conveyors are
available if requested.
Continuous longitudinal sealing is used to wrap magazines. If shrinking
is required, the film will be spot sealed to allow the enclosed
air in the newly formed bag to escape during the shrinking process.
Two different methods are used for the spot sealing: an ionizing
device that temporarily seals the polyethylene or polypropylene
film layers during the shrink process, and a glue dispensing device
for PVC. Transverse sealing is carried out by a thermostatically
controlled sealing bar. The sealing head moves forward with the
product during the sealing cycle and then opens and moves back to
begin the next cycle. The motion of the product is continuous.
