Application
The servo-based TS 7200 is a high-productivity multi-colour screen printing machine for decorating flexible plastic tubes and sleeves. TS 7100 is designed for in-line operation and is ideal for 24/7 production.

Features
The machine stations are built around an 18-station heavy duty rotary indexing ring. Each of the station on the indexing ring has a station head that takes two mandrels. A station head has its own servomotor that rotates the mandrels.

Servomotors drive the screens in the screen printing stations. The precise control offered by servo technology ensures high printing precision; the independence of the movements in the printing and drying stations enables operators to select optimum speeds for printing and drying. Each colour of a printed image can be individually stretched or compressed during printing by adjusting the speed of servomotor.

Each screen printing station features motorised screen adjustment:

• Circumferential adjustment – a servomotor driving a screen can advance/retard the screen in steps of 0.01 mm.
• Lateral adjustment – two servomotors can move a screen along the axis of a printing station in steps of 0.01 mm.
• Skewing – different travel of the two servomotors for lateral screen adjustment skew a screen.

Motorised adjustments 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.

A TS 7200 has Secure-Hold mandrels (SH-mandrels) as standard. SH-mandrels can handle tube batches that have variations of the inner diameters. These variations can be up to 0.15 mm.

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.
