Slitting & Rewinding

Automation greatly increases efficiency C

omexi offers several slitting and rewinding machines that use a variety of laser technology including

microperforation, QR codes and easy-open windows, among others. In recent years, Comexi has developed modular solutions for S1 slitter range, allowing greater automation of both the slitting process, and the process which immediately follows. This can be the case of conveyors, labelling, weighting, bagging, and palletising. The result is the optimisation of the process and increase of the customer's production. In many cases, the slitter is the final step of the converting process and the last to be in contact with the reels. However, it will still go through a few changes before reaching the final customer. All this post-converting processes, most of which are related to traceability and protection, can significantly undermine the effectiveness of the company if not handled properly. Connecting the dots between these processes, through customised automated solutions, can lead to a significant increase in productivity. Mainly this is due to the reduction of downtimes. Uptime can also improve through the

integration of online-finishing processes with the slitters. Comexi's laser technology

The comexi S1 slitter

facilitates the creation of easy-open applications in some packages without adding any extra processes. There are alternatives, such as scoring triple-opening lines and shapes. Additionally, the system allows the manufacturer to create window effects in the package, allowing the end consumer to see the contents within the packaging. This creates a more reliable brand perception with a natural and homemade touch. Many brands have used the laser process to communicate this idea by creating a clear plastic film window on a laminated paper pouch. Concerned about sustainability, Comexi seeks solutions which contribute to improving the environment. One of these

solutions is microperforation, which extends the shelf- life of fruits and vegetables. Recent studies show that approximately 30 per cent of food is thrown away because it has spoiled, particularly fruits and vegetables. The FPA (Flexible Packaging Association)

recently published various studies that indicate the extension of shelf-life as a result of suitable flexible packaging with MAP (Modified Atmospheres Packaging): the shelf-life of packaged green beans and grapes increases from seven to 19 days and seven to 70 days respectively. The creation of MAP relates to microperforation, a solution that is also developed with laser integrated with a slitter. The Comexi Slitting Business Unit is

incorporating all the benefits of Comexi Cloud, the most comprehensive online platform in the market to visualise, compile, analyse, and store data. Comexi Cloud is composed of an array of digital services linked to machines and the data these machines generate. Looking towards the near future, Comexi's objective is to have this platform as the gateway for artificial intelligence, and help customers operate machines with increasing efficiency.

unwind will accommodate a full master roll. A number of options can be added to complement inspection and finishing possibilities, including digital overprinting and separate converting systems. Scissor slitting, pneumatic crush slitting and razor slitting options are all available. Plain labels for both thermal transfer and inkjet applications, manufactured for any label printer can be die-cut to any shape or size dependant on requirements.

web viewing area, sliding splice table, dual rewind turrets and full rotary die stations. They will be used for finishing of pre- printed labels and for high speed production of blank labels, to complement the Labfax range of thermal label print systems and services. The Focus FS model is available with web widths of 250mm and 330mm and can be supplied with several different configurations – including up to two die stations, if required. The large capacity

comments, “As our orders have continued to increase, we were experiencing a bottleneck situation in our finishing department. We’d known Focus for many years and had no hesitation in ordering the two rewinders from them, both with full rotary die cutting. We have developed a good working partnership with Focus. Their equipment is well made and reliable, whilst the back-up service is excellent.” Focus sales manager, Antony Cotton

adds, “It has been a pleasure working with Labfax and very satisfying to see the business grow through hard work and investment in new equipment. Long may it continue.”
