Only a cam driven platen can deliver superb quality and high net outputs. The BOBST system increases the time available for each sheet to pass so that it can be transported smoothly through the die-cutter while at the same time reducing wear on cutting tools.
A BOBST Autoplaten® needs less patch-up and remains more stable during the run than any other, which means quicker setups, better product quality, and fewer stops in production. This is achieved using a principle called 'matched rigidity' which results in less deformation of the upper and lower beams when under pressure. Working hand in hand with the unique sector drive system, a tolerance free locking system for the gripper bar chains locks them into position without any vibration, giving highly accurate register, impression, and delivery.
Guaranteeing fast and precise tool positioning, Centerline® delivers quick machine set-ups, increased up-time, and superb finished product quality. Unique to BOBST, the patented Centerline® tool alignment system is found in every one of its flat bed die-cutters and hot foil stampers. By using a fixed master reference, which all movable elements of the machine reference to, tools can be pre-aligned, off-machine.
Controlling the flatness of each sheet as it stops for cutting, stripping and blanking is key to maintaining quality. A new Bernoulli sheet braking unit features an extension of the braking process to the very edge of the sheet, giving more control. The new unit also has an automatic self-cleaning system for reduced maintenance and increased reliability.
The stripping station on a BOBST die-cutter is designed to remove even the smallest pieces of waste at full running speed. Using dedicated or universal tooling, the station is up and running in no time, delivering outstanding performance and quality, whatever the job. All BOBST Autoplaten® presses feature Quick Lock systems as standard for fast and easy makeready.
BOBST flat-bed die-cutters with automatic in-press blank separation deliver the perfect balance of force and finesse needed to blank sheets absolutely precisely, whatever the lay-out or substrate. Each BOBST blanking station is conceived to handle blanking tools from heavyweight steel units to today's lighter weight systems such as the modular Angle Lock. Functions such as continuous pile lowering, constant batch compression, and automatic tie-sheet insertion to ensure perfectly stacked piles, while the modular non-stop grid allows the highest productivity levels. Digital centering means that small variations in the tools can be quickly and easily adjusted on-press. BOBST die-cutters with blanking stations also ensure trouble-free downstream processing.
The various feeder systems (Sheet feeder) allow a fast and constant transport of the top sheet to the laminating point.
A wide range of paper formats and paper base weights can be used.
By combining a number of innovative ideas, the new, fully independent, Smart Feeder II on the new EXPERTCUT 106 delivers substantially reduced set times, higher net outputs and easier maintenance, along with easier operation. A suction head with changed geometry and new features ensures quick setting and consistent feeding, whatever the substrate, while new feed table equipment reduces the number of sheets lost during a machine stop, is quicker to set, and delivers more consistent sheet transportation.
Automation includes all machine controll systems as well as operator interface panels.
Seamless, non-stop production for flat-bed die-cutters. By delivering pallets of work to the feeder of your BOBST die-cutter, then transporting the empty pallet to the machine’s delivery to be loaded with finished product, Automatic Pile Transfer (APT) reduces manual intervention and ensures a continuous supply of material. APT can also be integrated into your in-house logistics, piloting work from print to die-cutting, and on to downstream processes.
Optimal tie-sheet insertion – the new EXPERTCUT 106 calculates the optimum sheet feeding interruption based on the thickness of the carton. Considering the number of tie-sheets that need to be inserted, this new system delivers substantial time, output, and financial gains to users.
First and last sheet evacuation – To help carton makers ensure the quality of their finished goods, now top and bottom sheets can be evacuated automatically from production whether working in blanking or full sheet delivery mode.
Combining a range of BOBST technologies, Quick Change makes job changeovers simpler and faster than ever before. Dedicated tools can be fitted straight into your die-cutter – just as they were delivered from your tooling manufacturer – with the assurance that they will all be perfectly aligned and ready to run. The in-built 'programmed stop' means that a single button brings your machine to a halt in the perfect position to carry out a job changeover.
This new system allows users to lock and unlock all of the nonstop fingers at the push of a button, saving a large amount of time. Additionally, the fingers can be put into place with a universal positioning tool that is suitable for all job layouts, removing the need to order dedicated equipment with each new job. Like this, the finger’s position can be pre-set, off-machine, while the current job is still running, with the subsequent saving of make ready time.
This 100% no-sheet-edge-contact, dynamic register system dramatically reduces machine stops and perfectly registers die-cutting, or hot foiling, to the print on the sheet. By integrating Smart Feeder with Power Register II, feed related production stops are cut by up to 75%, resulting in reduced downtime and improved net outputs. Along with offering registration to either side of the sheet, Power Register II also offers a unique bottom print registration option which allows the conversion of litho-laminated microflute jobs with a quality and precision never before possible.
This latest generation of CUBE, BOBST's operator-machine interface, features revolutionary 'Touch & Set' navigation which makes even the most complex settings completely intuitive, saving valuable time. Now with a bigger, full color, touch screen CUBE3 gives the operator complete control of the Autoplaten®, from setting and running a job, right through to detailed fault diagnosis.
