Omet VaryFlex F1
Tuesday 06. October 2009 - The Omet VaryFlex series was considered the benchmark for package printing and converting when it was launched in 2001. In its latest design forms, VaryFlex-F1 and VaryFlex-C, it uses gearless and servo technology to offer the ultimate solution for the inline conversion of labels, flexible packaging, and folding cartons in one pass. It combines the widest choice of printing and converting options with short set up times and low waste levels to offer its users a fast ROI.
The VaryFlex-F1 has a sleeker profile, and VaryFlex C-a smaller footprint, making it an ideal solution for companies with limited production space. On both, the lower web path improves ergonomics, while the video cameras mounted front and back, form part of the operator interface for increased efficiency. This permits all job data to be recorded, analysed and instantly recalled.
Key features of the VaryFlex are its servo drive system, which produces better quality print and simplified and more accurate control of the machine. The combination of interchangeable flexo, screen, and foil units provide maximum production flexibility, and there is an optional rotogravure unit with a high efficiency drying hood.
The new UV-offset printing unit provides extra print capability and more cost effective plate making with better inline colour control. The offset unit has a slow setting speed and integrated pre-register, to reduce waste during start-up. The offset unit has interchangeable cassettes and format magazines. Supplied complete with UV curing, it is also available with a motorised cooling drum.
On all VaryFlex models, the use of sleeve technology means the next job can be prepared offline for fast changeover. Each sleeve is controlled by electronically activated brushless motors to ensure maximum precision and response time on variable print formats from 12″ to 33″. To stabilise the handling of a wide range of substrates, from 12-micron to 700-micron, the VaryFlex is fitted with a multi tension control system.
The innovative Vision 1 system is the key to quality control. Using motors, it automatically controls lateral, longitudinal and transversal register, and provides the operator with an electronic jog wheel to simplify register settings.
The VaryFlex is equipped with a rapid change anilox roller and ink pan system, and Omets latest QS (Quick Sleeve) system, which simplifies the automatic air input cycle to reduce format change and work times.
In the converting section, there are interchangeable die cutting stations, and two unique Omet units called Fly Cut and Twin Cut. Fly Cut allows different sizes from 6″ to 33″ to be cut without changing the machine set up. Driven by an independent motor, Fly Cut uses a synchronised scissor action to for clean and accurate cutting. The Twin Cut system produces a range of hollow punching formats by simply changing laminates. This avoids the need to replace heavy and costly die print cylinders.
Other finishing processes include cold and hot foil (with foil saving device), delam/relam, reverse side printing without turner bars, and lamination. Hologram transfer for the metallisation of paper and card using water based resins, and embossing are other finishing techniques available, while an overhead track can be fitted to allow easy insertion of the attachments to any required position.
At the delivery, automatic rewinders handle products delivered on the roll, with automatic waste removal. For sheeted products, the VaryFlex may be specified with a de-nester and non stop stacker for cartons, and pallet removal.
