Q: What specific features do the latest generation of slitters/winders offer that optimize a machine’s efficiency, and in turn, a company’s entire converting operation?

A: There are many features that we offer to ensure machine optimization on slitter rewinders. We have incorporated the latest in technology to increase machine production speeds while reducing cycle and changeover times. The use of operator-friendly computers with job storage files guarantees fast changeovers. The additions of automatic laser knife and rewind core positioning systems along with finished rewind roll material handling units make this all possible.

Q: If a completely new unit isn’t in a company’s near future, what steps could a converter take to optimize productivity of its slitting/winding process?

A: Many of our customers can upgrade their existing machines with options that specifically meet their individual needs. These optional features typically are automatic knife positioning units, laser core positioning systems and customized material handling devices. These features allow for an increase in the short term productivity and quality while extending the life of these older machines.

Q: What are the largest slitting/winding challenges facing today’s converters and how can companies address them?

A: One of the biggest challenges the converting industry faces is integrating different operators and substrates into the process. We believe that the solution is through technology that is simple to use. Having the ability to store all of the important job settings into the computer on the machine ensures that all of the operators are on the same path to success.

Q: How do recent models of slitters/winders enable users to manage substrate imperfections and generate the most salable product possible?

A: Numerous technological advancements have allowed for the total redefining of the slitting process. These advancements are all geared to promoting uniform quality and a more efficient workflow process. Closed loop unwind and rewind tension controls, our proprietary ALTS (Advance Linear Tracking System) for the lay-on rolls and a driven nip roll section all minimize the effects of problem substrates. The sole purpose here is to maximize quality, productivity and efficiency while using less manpower and energy.

Q: What prevailing trends in flexible packaging today do you anticipate will shape the future of slitting/rewinding and why?

A: Just-in-time production and the reduction of carbon footprints are trends that are shaping our industry today. As stated previously, numerous technological advancements have redefined the slitting and entire converting process. The sole purpose of these improvements is to maximize productivity and efficiency using less manpower and energy. The new EB-Wet-flex printing along with just-in-time production relays on a completely integrated press, laminating and slitting department to ensure that those users are ready for the future.
