Sapphire S2T

The key benefit of duplex turret slitter rewinders for users is productivity. This is achieved by the machine continuing to run whilst the machine, or operator, is offloading finished slit rolls and re-coring the rewind shafts. On duplex machines, the machine is not running; however, this loss of productivity can be reduced on a duplex turret slitter rewinder type of machine as the four rewinding shafts (two on each turret ring) ensure that the machine continues to run whilst these procedures are taking place.

The design of the Sapphire S2T is based on our Sapphire S2 duplex machine. No hydraulics on the machine makes it a clean operation for flexible packaging and medical applications, and the latest control technology makes the machine easy to use, with a minimal web path length. Easier and quicker setup times can also be implemented on the machine with further automation options, such as automatic knife and rewind core positioning systems.

The machine incorporates our unique ‘turret shaft support’, which ensures that the rewind shafts remain fully supported through the turret cycle. Due to this support, the machine is able to offer very fast cycle times, from the time the machine stops when the set length has been reached to the time it starts the next run.

The versatility of being able to run different substrates with no operator intervention or maintenance is achieved through our vacuum roller along with our driven lay-on roller system.

A range of roll-handling solutions on the rewind side of the machine can also be implemented on the machine, from simply fixed pedestals though to full robotics.
