Robust Frame
The construction of any
printing machine will dictate
how precisely and repeatable
it prints. The LP series
press utilizes a 40 mm thick
base frame weldment and 40mm thick ground steel mainplates.Once assembled, an unprecedented stiffness is achieved.
Primographic Print Head
With a fixed position large
diameter anilox and impression roll, our triangular based
print head offers a tremendous
advantage over other systems.
In-line style flexographic print
heads can not offer the
same plate cylinder positional
accuracy that our machines
provide.
Masterchange Inking System
The Masterchange system is a
total change of the inking
system including the anilox roll
and ink. The ink cartridge is
designed to be changed with
ink in the fountain. With this
system, colours can be
changed in less than two
minutes while the machine is
running production.
Web Transport Control
The key to good register control
is directly related to the accuracy
of the web transport. LP series
press uses servo driven draw
rolls and chill rolls to precisely
move the web through the press.
The print outfeed and the die
infeed have separate draw rolls
which isolate any web harmonics
created by the die cutting.
Advanced Servo Control
In addition to standard servo
control of the plate, anilox, and chill rolls, we also use Bosch Rexroth Indramat® servos to dynamically control the impression, and to automate the load/unload of the plate cylinder.
Integrated Die Cutting
The LP series die cutting
system is a massive structure
designed to withstand the
rigorous nature of folding
carton and liquid packaging
converting. This coupled with
our unique flexible magnetic
die mounting system makes
die changes effortless.
All CPS presses incorporate our exclusive Primographic printing technology to deliver quality that is equal to offset in tonal range. Using over 3000 pounds of force, our plate cylinder carrier is held in space with extreme accuracy and precision. This eliminates the traditional bounce that is associated with flexo printing. Our print quality is further enhanced by the large diameter gravity feed anilox roll which eliminates ghosting and starvation at higher speeds. With a programmable dynamic impression setting, job specific profiles can be uploaded to achieve the exact impression requirement for each job so that consistent density and dot gains are achieved throughout the entire speed range. These features coupled with our exclusive integrated register controller and superior web transport control results in the highest quality in flexo reproduction.
The Masterchange system allows for a total change of the inking system including anilox roll and ink. Using an open fountain or chambered fountain, colours can be changed in less than 2 minutes while the machine is running production. The offline component of the Masterchange system is called the cartridge table. Incorporated drives allow for off line make ready and cleanup of anilox roll/ink fountain and ink. Other features include off-line colour matching and cassette storage. With a pushbutton control, the pre-register accurately aligns the print-print to within 0.5 mm without any movement of web. This feature results in set-up waste of less than 40 meters. Automated servo control also loads and unloads the plate cylinder with extreme speed and accuracy. In summary, the LP series press has shorter make-ready times and less start-up and production waste.
The development of the LP series press targeted enhanced automation for high quality printing, improved efficiency, as well as extremely short make-readies. With its functional ergonomic modular design, the LP press can easily be
extended if additional features are required in the future. This highly sophisticated machine offers numerous valued added options to meet emerging needs in today's highly competitive
environmet.
The CPS LP series die cutter is extremely rugged and fast to change over. This modular based system was designed specifically for liquid packaging. The die modules are easily interchangeable and are locked and loaded hydraulically in only 30 seconds. The CPS die cutter supports all types of rotary die tooling – solid rotary pressure, solid crush cut, flexible rotary pressure, and flexible crush cut. With the ability to cut, crease, and emboss using a single station, the converting possibilities
are endless.
Featuring 80 mm tapered journals, our heavy duty die modules are designed to run bearer less tooling. This feature is very important for using solid or magnetic RP dies because of the requirement to adjust cylinder gap. Our die gap adjust mechanism allows the cylinder gaps to be changed by increments of 0.0025 mm in only seconds. Using our exclusive Auto Die Loader, flexible steel dies are precisely registered and mounted together all in one motion. Using our unique locking system, offline die makeready can
be accomplished in less than 2 minutes.
By precisely locating and l locking the die loader to the
die modules, accurate
mounting is easily achieved
each time the dies are used.
Integrated on each die module, the servo driven outboard stripper, effortlessly removes island, and side scrap. Our universal stripping disc design allows multiple jobs to be run on the same discs so tooling cost is minimized. A rigid robust frame design allows for zero waste between cartons and as low as 3mm of side trim. All components are quick release so discs, combs, and support rails are very easy to change.
The servo driven skew tape precisely separates and transports the cartons to the shingling conveyor. Separation between the upper and lower belt is pneumatically controlled so lateral position changes can easily be made.

“We are very pleased that we
have made the choice to go with CPS. Their build time, installation, and commissioning were nothing short of phenomenal. The LP 685 machine is well constructed and robust enough to handle the rigors of a demanding
production environment. The press is very operator friendly which is reflected in the very short make readies and minimal amount of material wastage”.
