VISIONLINE 1.6 - Production line

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.

The CUBE device (Control Unit BOBST Electronic) controls all functions of the machine and allows very precise setting of the print register. The rotation of each printing unit can be independently indexed following a programmed stop. This facility ensures that after a printing plate change or ink wash-up your print is in register from the first sheet.

A dedicated unit collects sheets needed for quality checks during production, as well as those ejected as non-conforming by the Registron® system or iQ300.

The gripper margin removal device is easily introduced from outside of the machine. It is possible to work without gripper margin (option).

Tension wheel for gripper bar chains and reinforced anti-noise protection.

During pallet evacuation and the loading of the next pile, the intermediate table places a layer on stand-by to ensure the high-speed flow of the layer of sheets into the feeder.

• Consistent loading and transport to feeder
• Lateral joggers align sheets at buffer

Tray for inspection of sheets during production, and ejection of sheets detected as out of register by the Registron® system.

An electrostatic device with suction eliminates dust at the sheet introduction.

Corrugated sheets are transported through the printing press by driven rollers and vacuum air. This vacuum transport system brings many advantages:

• No other contact with the printed surface
• High printing precision
• Quick running
• Easy operation thanks to room between groups

The suction plate ensures the precise introduction of all qualities of board from microflute to double-double.

Plates are easily located and precisely positioned by a centering system. Two plate lockups are provided as a combination: the BOBST 'Fix' system and the Matthews fast lock.

• Mobile delivery frame sets
• Straight lateral guides support
• Gripper opener device (optional)
• Closed-loop batch delivery program
• High pile 1'200 mm (optional)

Lateral joggers at the feeder with optional blower and lateral rear sheet guides. Includes removable, adjustable backing roll.

Simple system with a minimum of ink in circulation. Inking with two rollers, rubber and anilox, with movable reverse angle doctor blade. This enables the operator to adjust the volume of ink applied in response to the quality of the substrate.

Buffer feeder ensures no workflow interruption. Photocell barriers enabling easy access photocell barriers.

The intuitive palletization programming interface, using drag & drop, allows for automatic management of layer arrangement.

• Improved BOBST platen construction, including 4 connecting rods linking the crankshaft to the 4 toggles that support the mobile platen
• Very high cutting force
• Parallel adjustment of the cutting force by a single foot wheel
• User-friendly CUBE interface

Rear sheet support with lateral and rear jogging for perfect sheet alignment. Adjustable sheet backing roll. Rear batch lifter for easy grip in the event of a jam.

Enables the operator to remove one or more sheets to visually check quality.

Stripping station Featuring:

• Gripper opening for quality control
• Waste pinching system
• Precise ejection of small waste using male-female stripping tool
• No vertical movement of the sheet
• Easy access
• Mobile upper stripping frame

Tie-sheet inserter before palletization for perfect stability of the pile during transport.

Wide, low, work platform with chase loader for preparation of the next job during production.

Driers for fast color fixing. Duo-Technik UV or hot air systems guarantee the drying of ink between colors, avoiding smudging (option).

Fine adjustment of cutting plate to ± 0.1 mm in both directions.

Intermediate table places a batch on stand-by to ensure high-speed workflow during loading of the next pile (option).

• Piles automatically loaded and centered
• Synchronized lift process
• Rear jogging and blowing system

Perfectly aligned piles, vital for packaging machines, are produced by alignment on all four sides. Boxes are not marked due to the elimination of friction on delivery of the layer. The insertion of a tie-sheet before palletization ensures perfect stability of the pile during transport.

Sheet edge and/or printed mark reading infeed system that guarantees incredible print to cut register accuracy.

The operators’ safety is ensured by a system of claws which are introduced into the chain system at each machine stop or at the opening of a guard.

The platen diecutting presses are fitted with the latest electronic and mechanical advances in terms of sheet transport. Every movement has been engineered to obtain optimum transport, from the feeder to the delivery station, with smooth acceleration and deceleration of sheets. The lower gripper position enables much flatter sheet travel through the machine and the stresses on the contact points are greatly reduced.

Shingled stream of sheets prevents pressure differences on the suction plate.
