The new Unifit adapter sleeve from Rotec has been designed for the ‘Sleeve-on-Sleeve’ concept and its dimensions are aligned to the popular sizes of the Stork system. With the Sleeve-on-Sleeve system, adapter sleeves are used to realise higher repeat shifts - as a cost efficient alternative to the purchase of additional air cylinders or thick walled printing sleeves.
The Unifit adapter has its own air flow system, so all it requires are air holes on the operator side of the air cylinder. Optimum distribution of the compressed air can be guaranteed by a defined grouping of the individual air outlets. According to Dr-Ing Johannes Pietzka, Rotec’s sales and marketing manager, this makes the adapter largely independent of the air outlet arrangement on the underlying carrier cylinder. So the Unifit can be easily adapted to almost any customized carrier system.
All that rotec needs to manufacture the adapter are the sizes of the chamfer and the position of the first ring of holes on the carrier cylinder. The Unifit series is suitable for both conventional cylinder presses and quick change cantilevered machines. It can be combined with all types of sleeves.
Rotec also offers an H/C Unifit Bridge Adapter for seamless printing on a photopolymer basis, such as Cyrel round technology sleeves). This version has a compressible structure that is available in three different densities.
The Unifit range offers wall thicknesses of 10-60mm, with special sizes on request. The adapters can be provided with an L shaped metal reinforced interlock notch at wall thicknesses over 11.1mm, to ensure safe and accurate positioning.
