Turret winders

TREW SERIES TURRET WINDERS

PYRADIA TREW SERIES is our most versatile and compact series of automatic turret winders capable of handling multiple types of webs such as films, foils, paper and nonwovens.

The center driven turret winder is equipped with AC Vector drives mounted at each mandrel position. The drives are coupled through a pneumatically counterbalanced dancer roll, for tension control. System operation is fully automatic and PLC initiated for continuous operation. Automatic system control is included for turret rotation, flying knife cut & transfer sequence and general system operation.

The open frame turret winder (pictures 1-3) can handle 55” (4500 lbs) rolls up to 1200 FPM. It is equipped with a fully automatic flying splice mechanism, pneumo-hydraulic guiding system and dancer tension control system.

Clockwise and counterclockwise operation | Accurate tension & density control over the full roll diameter | Compact footprint | Innovative index drive system | Carriage supported by linear bearings for a smooth splicing & transfer | Ability to operate in minimum gap or pressure controlled mode of operation.

PHANTOM AXIS TURRET WINDERS

The phantom axis turret winder is equipped with the following: pull roll section, score edge trim, offset pivot guide and triple lay-on roll mode of operation. It can operate with the lay-on roll, disengaged, pressure controlled or in minimum gap mode. The latest technology is used to control the winder, through AC Vector drives, PLC and user friendly MMI. The toughest materials can be cut on the fly using our revolutionary back-knife support system
