Leesona Model 840 AW is the latest in the series of automatic tape and filament yarn winders. 
Capabilities includes winding polypropylene/polyolefin flat or fibrillated tapes, multifilament 
coated and twisted yarns, and other high performance fibers. It is especially designed to meet 
the ever-increasing demand for efficient and cost-effective tape and filament yarn winding.

Automatic changeover on full doff, including tape transfer
• Suitable for single and double tape winding
• Plasma coating bail roller & compensation bow bar for high performance fiber application  available
• Pneumatic linear motion of traverse unit for more efficient tape transfer
• Pneumatic bobbin release
• Uniform tape tension with centralized pneumatic step-less tension control
• Pneumatically operated back stroke brake unit for better package quality
• User adjustable length of tape on the bobbin
• Electronic gearing between cam and spindle produces uniform unwinding tension
• Transfer tail possible
• Machine controller: A Microprocessor based control system is used for setting and 
 adjusting the various machine and process parameters including storage of recipes
• Automatic changeover reduces need for suction gun resulting in lower compressed air consumption

•  Full color HMI touch screen interface. Program in English and customer's language. 
•  Programmable yarn tension, bail pressure, measured length, preset speed, alarms and 
  traverse functions.
• Tension compensated take-up for large tow winding capability.
• Highly accurate electronic programmable digital step precision traversing
• Ethernet or CAN bus for data retrieval and communication interface.
• Each winding position equipped with a high quality PLC and VFD for ease of maintenance and fully independent operation. 
• Heavy Duty Pneumatic package push off
• Heavy-duty steel frame construction provides rigid, stable winding platform.
• Label & QR label printing systems
• Remote access for maintenace and production management

The Model 987 can be manufactured in either of two technical designs: 1) positive pay-off and compensated control of tension by operating the torque motor with the flow of the yarn path. 2) tension controlled un-winding of fibers and yarns by operating the torque motor against the flow of 
the yarn path. Tension to the yarn strand is applied by a pneumatic cylinder connected to each compensator arm. Central control of tension is possible by using an adjustable, single precision air regulator interconnected to all positions. The Model 987 can be manufactured to accommodate a 
wide range of core diameters and lengths. Longer distance between package and compensator panel mimimize scuffing of yarn during un-winding. For applications which do not require precise tension control, the Model 987 is also available without the tension compensation control.

The Model 944 is a multi-purpose spooler was designed to wind many yarn types onto various sizes of flanged spools. 

Design and Features:
• Winding heads are mounted on a removable rigid panel for quick change-out and maintenance.
• Tension systems are front mounted for easy access & adjustment.
• An optional structure mounted waste aspirator is available.
• Available as 2, 3 or 4 winding heads high and up to 16 spindles in one structure.
• Simple yarn path for quick thread-up. 
• Spools from 100 DIN to 355 DIN.
• Safety lock-out switch in each cabinet.

Various traverse systems available for parallel or level winding, including ball screw type and 
computerized digital wind systems. Standard parallel winding and index winding options.
