C610C-NW Slitter Rewinder


The C610-NW is designed to function as a downstream inspection slitter for today’s narrow web presses. Its ease of setup and ability to quickly load and unload rolls, facilitate a ‘just-in-time’ operation. A differential rewind system compensates for gauge variation allowing the C610B-NW to rewind non-uniform web constructions.  The C610-NW duplex rewind mandrels eliminate web interweaving while providing sensitive tension control for each rewind roll. The C610-NW slitter rewinder can be operated in a ‘minimum gap mode’ for adhesives or cold seals as well as a dedicated narrow width option for narrow web rewind applications. For inspection applications, an optional overhead long in-feed web path allows the operator to examine the print in a convenient location above the rewinds. Full operator control and inspection can be performed from one location. This extended web path allows the operator to stop the web prior to defected material making it through to the rewind. The C610-NW offers an integrated ‘integral’ unwind providing a small footprint. The stand is equipped with linear bearing slides. The control system provides automatic web tension control through a pneumatic brake. Several unwind options are available including an upgrade to a separate shaftless stand.

Deacro’s roll lock differential air shafts

Auto Roll Lock Differential Air Shafts

Deacro’s roll lock differential air shafts are ideal for tension sensitive materials, clean running environments and rapid setup applications. Roll lock segments are stacked across the shaft eliminating the need to setup spacers. When rewinding is complete, the roll locks can automatically disengage for the finished rolls to be unloaded. Deacro offers a variety of designs for custom cores and with technology that can lock and unlock automatically and lock in forward and reverse winding directions.

Closed-Loop Rewind Tension Control

The closed-loop rewind tension control option gives operators the optimum level of control over the rewinding process. This option is particularly helpful for converters running tension-sensitive materials such as light gauge, extensible films. Load cells are used to read the actual tension and adjust the torque to the rewind shafts automatically for closed-loop rewind tension control. The slitter control system automatically adjusts the air pressure in the rewind shafts. This adjusts the rewind tension to match the load cell readings. This maintains the desired tension based on the base tension setting, taper tension setting and current roll diameter.

Servo/Auto Laser Core Positioning

To reduce setup time, lasers can be supplied to indicate the rewind core locations. Operators simply line up the cores with the lasers. The servo positioning version eliminates the initial setup and positioning of the lasers. The operator waves a hand near a sensor to initiate the laser to move to the next required core position as saved in the file recipe to match the positioning of the knife locations.

Manual Laser Core Positioner

The manual laser core positioning system uses multiple lasers to indicate the required location for cores on the rewind shafts. The position of the lasers can be easily adjusted by the operator with quick disconnects and tool-less locking. After locating the lasers, operators simply line the edge of the cores with the laser for quick and accurate positioning

Roll Pushing

Automatic unloading of finished rolls onto a receiving tree can reduce the slitter downtime between set changes and provide increased safety for operators. The electric design provides smooth removal of the finished rolls at the touch of a button.

Overhead / Web Path Options

Deacro offers a variety of web path options including the standard underfeed, optional overhead (for clean room applications) or an extended inspection web path option. Extended web paths can be used to add secondary processes such as web inspection while allowing defects to be stopped at a central location for web editing before defects reach the slitting section.

Safety Fencing / Scanners

Deacro offers a full range of safety features and options to ensure safe operation while maintaining operator access as required. Flexible designs use a combination of safety fences, gates, light curtains and programmable laser scanners to suit every application.
