UDB / CMU Unwind Modules
Modular Unwinding Solutions for Flexible Converting Workflows
The UDB and CMU Unwind Modules are modular, standalone unwinding solutions designed to integrate seamlessly with existing printing, converting, and finishing equipment. Built to support a wide range of production layouts, these modules provide controlled, reliable web delivery for workflows that require precise tension management and safe handling of large or heavy rolls.
Whether you are expanding an existing system or building a custom production line around a specific process, Aztech Unwind Modules offer the flexibility to configure unwinding capability without redesigning your entire operation.
Where UDB and CMU Unwind Modules Fit Best
Designed for production environments that require dependable, modular web handling.
System Expansion
Add controlled unwinding capability to existing presses or converting systems.
Custom Production Lines
Serve as standalone unwind stations feeding printing, laminating, coating, inspection, or finishing processes.
Large and Heavy Roll Handling
Safely manage large-diameter rolls with architectures designed for stability and control.
Flexible Layouts
Support left-to-right or right-to-left web paths to align with plant layouts and process flow.
Choosing Between UDB and CMU Unwind Modules
Both UDB and CMU modules share a common design philosophy focused on reliability, tension stability, and modular integration. The primary difference lies in how rolls are supported and loaded, which determines suitability based on roll size, weight, and material handling preferences.
UDB Unwind Module
Cantilevered Unwind for Efficient Roll Handling
The UDB Unwind Module is a compact, cantilevered unwind system designed to process large rolls that are loaded using secondary roll handling equipment such as the Aztech RollRunner Series. Its open-sided design allows efficient roll loading while maintaining stable web delivery.
Key Characteristics
Cantilevered unwind architecture
Supports roll diameters up to 40 inches
Available web widths: 10", 13", 16", 18", and 20"
Designed for use with external roll lifting and handling equipment
Standard Features
Dancer-activated disc brake
Choice of 3" or 6" pneumatically expanding unwind spindle
“Set-and-forget” constant tension web control
Configurable web direction (left-to-right or right-to-left)
Optional Enhancements
Electro-mechanical web guiding system with ultrasonic sensing
Manual cross-cut splice table
CMU Unwind Module
Cradle-Mounted Unwind for Heavy-Duty Applications
The CMU Unwind Module is a dual side-plate, cradle-mounted unwind system designed for exceptionally large or heavy rolls. Its supported cradle architecture provides additional stability and can be equipped with an integrated roll lift system to automate roll loading and positioning.
