Xsystems rotec User manual

USER GUIDE rotec®
rotec® sleeves and adapters are manufactured using the very latest production technologies. The materials used are subjected to constant
quality control procedures carried out at our facilities. In order to utilize the product properties of rotec® sleeves and adapters in the most
ecient manner and to increase the life time of your sleeves/adapters, you should comply with the following recommendations. In case of
questions or technical problems, please contact customer service or one of our sales representatives.
Air pressure
+ The air pressure measured at the air cylinder should be within the range of 6 to maximum 8 bar
(87 to maximum 116 psi). DO NOT EXCEED 8 BAR /116 PSI.
+ The air volume low should not fall below 12 litres per second (0.42 cubic ft. /sec.).
+ Please ensure that the air can pass freely, i.e. the air line is not pinched or damaged.
+ Unnecessarily long or branching supply lines may lead to a drastic fall in air pressure.
+ The compressed air system and cylinder surfaces should be free from moisture, oils, lubricants & inks.
Check for blockages in the air outlet holes before each usage.
+ For all rotec® Atlas & CFX Adapters and ULW Adapters:
Cleaning and care of rotec® sleeves and adapters
+ Please inspect sleeves/adapters routinely for damages of the inner sleeve, the surface and notch as well as register pin of adapters before usage.
+ Damaged sleeves/adapters should not be used for printing.
+ Oil, lubricant, ink and tape residues should be removed as quickly as possible to maintain the surface properties.
+ Stronger residues can be removed with a soft nylon brush.
+ Suitable cleaning solutions are ethanol, propanol, isopropanol, or water.
+ Never use solvents containing grease or oil as they negatively aect the surface properties.
+ Never treat the sleeves/adapters with acids, alkaline solutions, and salt solutions or with any sharp objects that could damage their surface.
+ The entire surface should be cleaned with minimal amounts of cleaning solution and a clean cloth. Residual solvent should be wiped o immediately.
+ As solvents are poorly evaporating from plate/tape gaps, plates should always be demounted after use. When cleaning sleeves or printing plates
while mounted, please make sure no solvent remains between the tape and sleeve.
+ Wait at least 30 minutes after cleaning sleeves/adapters to allow the solvents to evaporate completely.
+ The sleeve ends should be protected against liquids at all times.
+ To maintain good mounting characteristics, clean the inner base with an appropriate cleaner.
+ Glass fibre filaments which loosened from the inner base can be ground o. Do not pull out fibres.
WARNING: PREVENT SERIOUS OR FATAL INJURY
Regularly check the airlow through the weep holes, which prevent pressure buildup.
There are 4-6 weep holes (3-8mm wide, depending on wall thickness) on each side of the adapter on the end cap.
1. Apply air for 1-2 seconds into 1 of the weep holes. CAUTION: Wear eye protection during weep hole check.
2. Check that air comes out of the other weep holes. Two people are required to simultaneously monitor weep holes on both ends.
3. If one of the weep holes is blocked (no air coming through), clear out the blocked weep hole with a 2.5mm drill bit manually.
4. Repeat on the remaining weep holes until air flows through all weep holes.

Omega surface technology
+ rotec® sleeves and adapters have been developed with the -Surface Technology to prevent inadmissibly high electrostatic charging when
printing inks and varnishes containing solvents on flexographic presses.
+ rotec® sleeves and adapters with -Surface Technology comply with BG information, status 11/2003, Order No. 452 and ATEX EU Directive
No. 2014/34/EU (formerly ATEX 95), meeting the required bleeder resistance of a maximum of 106.
+ The rotec® -Surface Technology enables electrostatic charges on the complete surface to be conducted.
+ The bleeder resistance should be checked each time before use.
+ The functional principle only works when the air-cylinders are grounded.
+ No liability is accepted for sleeves/adapters reworked by manufacturers other than XSYS.
Special advice for conductive rotec® sleeves/adapters with compressible surface
+ To ensure a permanent conductivity, please do not expose the sleeves/adapters to high temperatures, e.g. removing the plate with a
hairdryer, hot-air-radiator or other similar equipment.
+ Do not apply isolation materials like hairspray, varnishes or other additional layers as they have a negative eect on the conductivity.
+ Do not use abrasive paper or hard brushes on the surface.
Plate mounting
+ Oil, lubricant, ink and tape residues aect the adhesion properties of the tape.
+ To apply the tape without bubbles on the sleeve, the use of a soft plastic roller is recommended.
+ The plate must be mounted bubble-free on top of the tape – a soft plastic roller is recommended.
+ Exposed surfaces of the sleeve can be protected eectively with PVC/PE adhesive tape.
+ Never apply an edge sealer directly on the sleeve – apply the edge sealer on the tape only!
+ Cutting might damage the surface, therefore please use the rotec® Cutting Ruler.
+ Adjust the tape and plate gaps by a minimum of 30° in order to avoid edge lifting of the plate.
Plate demounting
+ Remove the plate slowly and carefully with a constant tension – too much tension may damage the plate.
+ Remove the tape by slowly pulling it back from the corner at an angle and pull it o in one piece.
+ Remove any residual tape immediately (see Cleaning and Care).
Storage of rotec® sleeves and adapters
If you do not use a storage system for sleeves, please pay attention to the following points:
+ In principle, sleeves/adapters should be stored in an upright position.
+ Sleeves/adapters stored upright must be secured to prevent them toppling over.
+ Sleeves/adapters should not be stacked on top of each other.
+ Constant weight loads and stress may aect the TIR (Total Indicated Runout) of the sleeves/adapters.
+ High air humidity at higher temperatures (tropical climates) aects the service life of the sleeves/adapters.
+ Specified outer diameter is valid only at a storage temperature of 20-21 °C (68-70 °F) and 50% humidity.
