UDB/CMU Unwind Modules

Since every client has unique converting needs, AZTECH Converting Systems has developed two modular and flexible unwind systems which can be used in tandem with existing printing and converting equipment.


The UDB Unwind Module is a compact Cantilevered Unwind that allows for handling roll diameters of up to 40 inches, and is available in 10, 13, 16, 18, and 20 inch widths.

The UDB module is designed to process large rolls that would be loaded with a roll handling and lifting system such as the AZTECH RollRunner Series

The base system is comprised of a heavy-duty, dancer-activated disc brake and choice of either a 3-inch or 6-inch diameter, pneumatically expanding unwind spindle. Additional standard features include “Set and Forget” constant-tension web control and your preference of web direction configuration….right-to-left or left-to-right.

Optional electro-mechanical web guiding system with ultrasonic web sensing for handling of both opaque and transparent substrates, and cross-cut splice table can be provided upon request.

The AZTECH CMU Unwind Module is a dual side-plate, Cradle Mounted Unwind capable of processing large diameter and very heavy rolls. The CMU may be equipped with an integral hydraulic lift system, should you require the ability to automatically lift and position rolls into the unwind module without use of a standalone roll lifting system.

Like the UDB, the base CMU system is also comprised of a dancer-activated disc brake and choice of either a 3-inch or 6-inch diameter, air expanding unwind spindle. Additional included features are “Set and Forget” constant-tension web control and your preference of web direction configuration….right-to-left or left-to-right. The CMU Unwind Module is available in 13, 16, 18, and 20 inch widths.

Electro-mechanical web guiding system with ultrasonic web sensing for handling of both opaque and transparent substrates, and manual cross-cut splice table are available options.
