Processing Technologies International, LLC (PTi) has introduced a complete line of sheet extrusion winding systems. The line-up contains several styles of winders including: Cantilever, A-frame, Turret and Automatic. Additionally these winding systems are supported by a line of sheet accumulators featuring fully integrated pneumatic tension control.
“Market demand drove us to develop these winding solutions”, stated Dana Hanson, President of PTi. “Sheet producers are focusing more on turnkey solutions for their production requirements. Sheet winding systems are a natural extension of our product line. We have developed several styles of winders to suit the different needs of our customers. For example, the Automatic winder provides fully automated features including cut and transfer, shaft extraction, roll un-loading / core loading and roll weight measurement and recording.”
Several of the winders are capable of differential shaft winding allowing for multiple webs on a single shaft. “We have been very pleased by the response from the market to date. We’ve installed multiple units since their introduction with several others on order. Although initially developed solely to support our sheet extrusion systems we’ve also decided to offer the winders/accumulators as stand alone units” stated John Chalmers, Vice President of Business Development.
PTi will be installing a 2,500 lb/hr dryer-less twin screw extrusion sheet system as part of the HVTSE (High Vacuum Ttwin Screw Extrusion) technology to demonstrate processing PET and PLA along with other polymers during in the 1st quarter of 2011. This system will also feature a Cantilever Winder and Sheet Accumulator for customers to view first hand their ease of operation and high quality construction.

n January 2010, PTi entered a 10 Year Strategic Business Alliance (SBA) with Italian equipment maker Luigi Bandera to offer dryer-less PET/PLA Sheet Extrusion Systems.
The patented Bandera technology referred to as HVTSE (High Vacuum Twin Screw Extrusion) employs a single atmospheric and dual high vacuum vent system with a co-rotating twin screw extruder. This unique approach, allows moisture and other volatiles to be removed as part of the extrusion process. In the case of recycled PET, the need for recrystalization of the material is also eliminated. The energy savings from the elimination of these drying and crystallization steps can run upwards of 30-35% over the conventional method.
The HVTSE Technology is available exclusively from PTi throughout all of North America. If you have further questions please feel free to contact us at email@example.com.

In PET sheet extrusion, the maintenance and preservation of the material IV is a key requirement of the process. Intrinsic Viscosity (IV) is a measure of the molecular weight distribution of PET. The mechanical characteristics of PET are improved at higher molecular weights (higher IV) and reduced at lower molecular weights (lower IV). Should the IV of the extruded PET sheet drop below acceptable thresholds, the end product mechanical properties can be compromised to unacceptable levels.
The ability to monitor and track the relative level of the material IV in-process and in real-time is an invaluable process tool. Identifying any deviation in the processing conditions and being able to take corrective action to address those conditions is critical to maintaining consistent and efficient production.
The IV monitoring system was developed to compliment the HVTSE (High Vacuum Twin Screw Extrusion) system being offered for “Dryer-Less” production of PET sheet. The patented HVTSE system was developed by Luigi Bandera and is offered exclusively in North America by PTi as part of a Strategic Business Alliance between the companies. Bandera has installed more than 80 of these “dryer-less” systems world-wide.
The unique technology represented in PTi’s real-time IV Monitoring System is based on a precise measurement of melt temperature and capillary piping pressures such that the viscosity and subsequent IV can be accurately calculated. These results are benchmarked against the ASTM D4603 Solution Test Method for measuring IV and possess an accuracy of +/- 0.02 dl/g.
The extracted test data is continuously fed into PTi’s flagship TITAN control system, where it can be displayed, stored and readily accessed.
PTi will be installing a 2,500 lb/hr dryer-less twin screw extrusion sheet system as part of the HVTSE technology to demonstrate processing PET and PLA along with other polymers during in the 1st quarter of 2011. This system will include the IV Monitoring System providing customers with a hands-on opportunity to evaluate the system capabilities.

Two Southern California processors have boldly gone where no one has ever gone before.
"We tend to jump on things early," says John Kittredge. "F-K has been a pioneer in a number of things. Our earliest example was converting HDPE margarine tubs to ABS. After that we were a leader in thermoforming polypropylene, and then APET." Now it's PLA biopolymer.
PTi offers several unique roll stand configurations that are used to produce thin thru thick sheet gauges (0.006-1.000 inch/0.15-25.0 mm) at narrow thru wide sheet widths (24-130 inch/600-3,300 mm).

PTi leads the industry in control automation.
Extrusion machinery at the June NPE show in Chicago showed inventive ways to get more out of your floorspace and materials.
This NPE show won’t have a lot of extruders on the floor, either running or static. Instead, look for videos and announcements of new technology. You will also find lots of ingenious peripheral devices to improve output and quality and save resin. Some will do all three, and cost less into the bargain.
PTi has just introduced a new series of sheet extrusion systems called GLOBALINE®. This design concept provides a cost effective sheet extrusion solution for a world marketplace.
Clear Lam Packaging Inc. is a mid-sized, family-owned packaging company with an enviable growth rate of over 20%/yr, unusual at a time when many mid-sized packaging companies are being bought out and disappearing. The secret, Clear Lam believes, has been its aggressive investment in R&D.
The second generation of Titan and Titan Plus computer controls, introduced in July by PTi Processing Technologies LLC in Aurora, Ill., distributes operator information over three screens simultaneously and also distributes the computing power behind them.

The industry’s first quick-release mold-clamping system for cut-sheet machines made its debut this fall at the SPE’s 15th annual Thermoforming Conference in Milwaukee.
NPE will show higher outputs of practically everything, as advances in grooved feeds, servo drives, screw torque, mixing screws, dies, and downstream cooling, cutting, and handling make everything run faster.
Gearless extrusion, cryogenic profile calibration, wireless data communications, and automatic start-up of blown film lines are just a few of the new ways to raise efficiency and output that were highlighted at NPE.
