Application
The TH 8130 is designed for screen printing and flexo printing onto flexible tubes or sleeves. The combination of two printing processes allows printers to take advantage of the strength of each printing process: flexo printing for half-tone printing of stunning photo-realistic images and screen printing for printing vibrant solids and pin sharp texts. Reliability and speed make the TH 8130 ideal for 24/7 production.

Features
The machine stations are built around a 22-station heavy duty rotary indexing ring. Each of the station on the indexing ring has a station head that takes a mandrel. A station head has its own servomotor that rotates the mandrel.

The machine has eight printing station, each printing station can take a Flexo printing unit or a screen printing unit, and these units are interchangeable.

Flexo printing units
Servomotors drive Anilox rollers and Flexo plate rollers; flexo plate rollers are easily exchangeable for off-line mounting of flexo plates. Ink is continuously circulated from ink reservoirs to the ink chambers and back to the reservoirs.

Each flexo printing unit features motorised flexo plate positioning

• Circumferential adjustment in steps of 0.01 mm.
• Lateral adjustment in steps of 0.01 mm.

Dynamic Roller Positioning ensures consistently high flexo printing quality.

Screen printing units
A servomotor drives the screen in a screen printing unit. The precise control offered by servo technology ensures high printing precision. Each colour of a printed image can be individually stretched or compressed during printing by adjusting the speed of servomotors.

Each screen printing unit features motorised screen adjustment:

• Circumferential adjustment in steps of 0.01 mm.
• Lateral adjustment in steps of 0.01 mm.
• Skewing – different travel of the two motors for lateral screen adjustment skew a screen.

Printing parameters of the flexo printing station and screen printing station can be controlled from the touch screen or the operator stations; therefore it is not required to open the interlocked guards while the machine is running. The independence of the movements in the printing and drying stations also enables operators to select optimum speeds for printing and drying.

A TH 8130 has Secure-Hold mandrels (SH-mandrels) as standard. SH-mandrels can handle tube batches that have variations of the inner diameters.

ISIMAT’s Spot UV LED (option) enables the printing of whole length wrap-arounds, the trailing edge of a wrap overprints the leading edge, the overprint is virtually invisible.
