The Sapphire S2 is the flagship duplex slitter-rewinder from Ashe and is designed to process all flexible material substrates, at high speeds with ultimate precision. The concept of this slitting machine is to offer a simple manual solution through to a fully automated slitter rewinder that has minimal operator intervention. Using the latest control technology makes the machine extremely easy to operate and gives the machine the flexibility many converters demand. The machine is available in various unwind configurations to suit most applications and products. All forms of slitting can be accommodated on the Sapphire s2 and there is a range of automation solutions on the slitting station for ease and speed of knife setup. This automation can also continue to the rewind section where features such as automatic core indication, or automatic core positioning can be accommodated.This slitting machine is the cleanest solution for flexible packaging and for medical products as there are no hydraulics on the machine. All unwind movements are powered electrically. Our vacuum roller technology is also on the machine to give perfect tension isolation between the unwind and rewind which requires no operator intervention or maintenance.
