2.1.2 Intake tract-
ion group electronically controlled front-feed device for maintaining constant pre-selected sheet tension upstream the unit for intermittent sheet transport.
2.1.3 Shutdown
facility automatic shutdown facility between all traction groups for stopping the machine if the sheet tears.

The format is set through a rotary switch mounted on the control panel.
The electronically controlled drive monitors the print and repeat lengths and keeps them constant.
2.2 Collective print
for letter set the ungummed obverse side of the sheet is printed on. None of the cylinders runs on bearer rings; this makes it possible to put them in without changing adjustments in the My area. The entire printing unit has an oil-tight and dust-tight enclosure on the drive and operator side.
2.2.1 Print cylinder Without lining, surface is corrosion resistant. Supported without backlash in several rows of high precision, adjustable roller bearings.
2.2.2 Rubber
blanket
cylinder 2 print segments on the circumference, for each segment an end to end rubber blanket, which is as wide as 3 plates, is spanned.

Thickness of the rubber blankets: 1.6 mm
2 cushioned holding strips for the overlay
Thickness of the overlay: 0.4 mm
Supported without backlash in several rows of high precision, adjustable roller bearings.
An automatic washing device is installed to clean both rubber blankets.

thickness of print plate 0.83 mm, undercut 0.9 mm.
Print segment circumference 580 mm plus stretching device; i.e. up to 22 brands of size I can be printed in succession.
Each form cylinder is equipped with 3 adjacent stretching rails at the beginning and end of the segment. Thus 3 print plates can be clamped adjacent to each other at the same time.
2.2.4 Turning
printing
on and off for printing cylinder, form cylinder, inking rollers and ink vibrators
Print on: all printing cylinders and inking rollers together or individually
Print off: automatically in case of web rupture or ingress of tramp matter
Manual switch-off of cylinders or of inking rollers allowed. Form inking is possible at standstill of plate cylinder.
For each plate cylinder position it is ensured that the inking rollers will not ink the plate ground.

Readjustment of inking rollers during the daily production is not required when using the temperature control.
All rollers can be adjusted during running operation.
4 friction rollers with lateral oscillation of 0 – 30 mm,
The drive of the lateral oscillation is hydraulic type with electronic control. Lift and frequency can be infinitely varied during the running operation and will be shown by a dial indicator.

Roller train travel locking with 4 catch hooks and locking pins facilitating equal settings for each position.
Safety device incl. 2 safety bars to prevent accidents during move of roller train.
All gears of the roller train gearbox are ground and run in an oil bath. The roller train is provided with an oil and dust tight enclosure both on drive and on operator’s side.
Temperature control with closed circuit.
Reserve: ½ a set of rubber-lined rollers
