The AP4050 unwinder/rewinder group modules are a serie of compact, powerful and affordable units which can be used to easily unwind and rewind paper rolls in combination with a Zebra compatibile print engine.
A constant tension of the rewinded paper is granted thanks to a clever servo dancer arm, controlled by a microprocessor, which works together with a micro-step driven stepper motor.
The standard rewinder group, designed to hold a 300mm diameter paper roll, is available in several versions: for 4" and 6" paper width, in Right Hand and Left Hand version, and in Black or White anodized aluminum. A 350mm diameter unwinder is also available.
Several options, like an end of paper photosensor or a three colors LED alarm lamp, are available (see the complete list below). All the options can be easily connected to the unit with industrial grade M12 connectors.
This unit works in perfect combination with the AP4050 pneumatic group or any AP4050 applicator group and can be controlled and configured via the AP4050 Display Controller. Furthermore, a USB interface is available as standard: thanks to a sophisticated software, which can run under Windows, Linux or MAC OsX, it is possible to remotely configure and monitor the unit, perform advanced diagnosies and firmware updates through an intuitive and user-friendly interface.
The AP4050 rewinder unit provides also a D25 connector and several I/Os for advanced integrations.
