Contents

One Unwind unit 50"(1270mm) capacity, with 3"dia shaft, including electronic sensing web guide, splicing table, pneumatic roll lift and tension control system with tension transducer and electro magnetic brake.

    • Pneumatic mandrel 3" (76mm) diameter.

    • Electronic web guide, correcting continuously with great accuracy for the slightest alignment variations. (Including parameter set up control)

    • Programmable tension control system with tension transducer and electromagnetic brake. (Dynaspede) including two load cell units

Variable infeed: with driven motorised control (allowing for variable conversion of heavier material etc).
1 Turn bar for reverse printing (mobile between any print unit).
Delam / Relam self-adhesive labels.
9 Printing Stations (Cassette design) including laser engraved ceramic anilox rolls with helical gears, printing cylinders, and high precision ground impression cylinders.

Comet RS 340 press has a self-cleaning plate feature. This system increases the efficiency of the press by removing residual ink from the plate cylinders. The anilox and plate cylinders release alternately, transferring residual ink to the web, leaving the printing plates clean and minimizing the need of hand to clean the plates after press stops.

Auxiliary motor for anilox cylinder when the press stops
High precision ceramic anilox roll with micrometric adjustment
Cassette design in 9 printing units
Fast set-up for anilox cylinder replacement
Automatic anilox roll throw-off without loss of registry when the press stops
Double side frame
Quick removal plate cylinder without using of tools
Fine adjustment of plate cylinder
Running lateral adjustment (Manual)
Running circumferential adjustment (Manual)
Easily removable plate cylinder by extracting the shaft without the use of tools
Automatic self-cleaning throw-off without loss of registry when the press stops
Automatic plate cylinder throw-off without loss of registry when the press stops
Plate cylinder position can be changed in gear without removing the parts
Designed and built to allow an easy access to all parts, for easy cleaning, maintenance or replacement
When press stops, the anilox roll continuous to rotate. Hence avoiding permanent damage, which is caused by ink drying on the anilox surface
9 Reverse angle doctor blade system with stainless steel ink tank
Reverse angle doctor blade with fine adjustment and metering roller
9 Short High efficiency drying units including infra-red lamps, hot air blowing/suction system, can select high, medium, and low temperature hot air
