costs and change-over time on the press

• Inner/outer diameters, airholes, notches etc. are equivalent to the hard bridge-adapters

• They have a compressible top-layer. The functionality can be compared to a compressible tape, but they can be used for many print-runs

• The compressible adapter is a MUST for printing with Cyrel® round Thin

• The print-characteristic can be adjusted to the • The print-characteristic can be adjusted to the press with different foam-hardnesses (e.g. soft, medium and firm)

Hard bridge-adapters

• Adapters enable a reduction of weight and cost vs. steel-cylinders

Cyrel ® round – Press Adapters

vs. steel-cylinders

• In most cases hard adapters are just used for imaging blanks on the CDI

• The inner diameter matches the outer diameter of the CDI‘s steel-/carbon-mandrel, the outer diameter corresponds to the inner diameter of the sleeve

• The adapter has got airholes on the edge (usualy 4 to 8 depending on repeat) guiding the air from the airholes of the cylinder to the surface of the adapter

• It should have additional airholes on the face depending on lenght and repeat• It should have additional airholes on the face depending on lenght and repeat

• The adapter should have a interlock to lock the adapter on the mandrel‘s register-pin, otherwise the adapter could slip when mounting the printform

• In case of simple designs and good press-conditions the hard bridge adapter can be used as a print adapter in combination with Cyrel® round Classic

Cyrel ® round - Handling Recommendations

When setting the sleeve start with the upper edge o f the adapter/air cylinder, not the lower edge


Apply only light pressure when setting the sleeve a t the adapter/air-cylinder to avoid nicks, kinks, cracks or other damage to the sleeve edge.


Please apply pressure only from the side during mou nting of the sleeve. Otherwise the sleeve will be squeezed a nd can be damaged.


The adapter/air-cylinder should have a chamfer to a ssist during mounting, otherwise mounting is nearly impossible


If an adapter is used it should be insured that it is fixed properly for sleeve mounting and demounting. For example, a pin-notch locking system as shown be low.


The compressed air flow system is critical for smoo th mounting and demounting . Main influencing factors are air pressure and flow rate

• The hole position and hole pattern on adapter/air-cylinder must provideadequate air flow under the sleeve.

• Mounting air pressure is 4 – 8 bar (58 - 116 psi) and volume of not lessthan 12 liters/sec. (0.42 cubic ft./sec.) The inner diameter air lines shouldbe not less than 6 mm. This assumes adapter/air cylinder diametertolerance of -0, +0.015 mm (-0, +0.0006 in.).

• If the mounting requires too much force, this can result in a (reversible)torsion of the sleeve.

• The surface of the adapters/air cylinders should be clean.

• The air supply should be dry and clean.

Cyrel ® round - Repeat Lengths

Available repeats are based on the Stork-System wit hincrements of 10 mm (example 340 mm, 350 mm...) .

Advantages

• Open system within the industry standard

• Cost advantages due to a limited number of necessary toolings

• Simplified communication (only type and repeat is necessary)

Options for variable print lengths (not matching 10 mm steps)Options for variable print lengths (not matching 10 mm steps)

• Gearless presses allow to shorten or elongate the repeat on press

• Vary the thickness of the polymer-layer while maintaining thestandardized inner diameter

Cyrel ® round - Repeat Lengths

Mounted on the same Stork-Adapter a Cyrel ® round Thin sleeve prints a 10 mm shorter repeat vs. a Cyrel ® round Classic sleeve

The Stork-System is based on a wall thickness of 3,125 mm

Cyrel® round Classic (wall thickness 3,17mm) is directly related to the Stork-size

Cyrel® round Thin (wall thickness 1,57mm) is indirectly related to the Stork-size

example for storage arearobust single sleeve box

• Requires the same conditions as the storage of plates

Cyrel ® round - Sleeve Storage

• Should be stored either vertical or horizontal in the special transport box

• No limitations regarding storage time for printed sleeves under appropriate conditions

• The rules an recommandations for cleaning of Cyrel® photopolymer plate cleaning also apply to Cyrel® round sleeves

Cyrel ® round - Sleeve Cleaning

to Cyrel® round sleeves

• We recommend a mixture of Ethanol (~90%) and Ethylacetate (max. 10%)

• For manual cleaning a brush with natural bristles should be used

• Plastic bristles tend to brittle after time and often show sharp edges

• After cleaning the sleeve should dry before storage• After cleaning the sleeve should dry before storage
