Sapphire S2T

Turret shaft technology for maximum output, minimum downtime

The choice for the converter that is looking for maximum productivity and minimum downtime. This is achieved by the machine continuing to run, whilst the operator (or machine) takes off the finished rolls and puts new cores onto the rewind shaft.

How it works

Sapphire S2TWide-Web Duplex Turret Slitter Rewinder

The key benefit for users of duplex turret slitter rewinders, is productivity. This is achieved by the machine continuing to run whilst the machine, or operator, are 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 type of machine as the 4 rewinding shafts (2 on each turret ring) ensures 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 webpath length. Ease 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 turreting 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 layon roller system.

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