PTI LLC introduces low-cost leak tester
Packaging Technologies & Inspection LLC has introduced the Pti-172, a high-speed, continuous motion leak tester for containers - billed as a lower-cost alternative to rotary inspection systems.
The Pti-172 requires 70 percent less floor space than other systems and can test a range of bottles and containers, with fast changeover between products.
The self-teaching Learn software helps automate setup and makes the leak tester run more efficiently, the company said.
PTI is based in Tuckahoe, N.Y.

Evolution line provides flexibility
Welex Inc. said its Evolution sheet extrusion lines have leak-proof Victaulic fittings and direct-acting rigid roll gap stops with digital motorized adjustment for positive roll gap settings without deflection.
The lines can accept different-diameter rolls.
On Evolution take-offs, direct-acting linear bearings replace the swing arms that most competing designs use for roll movement. Roll closing pressures are continuously adjustable to virtually any desired pressure, thanks to a new accumulator-backed, air-over-oil loading system.
Also new from the Blue Bell, Pa., company is the Hercules industrial sheet line, specialized to cool thick, wide, commercial-grade sheet. Welex said thick sheet must be cooled very carefully to avoid distortion from differences in shrinkage of the colder surface layer and the hotter inner layers. The machine has large-diameter heated rolls followed by long cooling conveyors. To accelerate the cooling, Welex sometimes adds banks of high-capacity air cooling fans or temperature-controlled immersion baths.

Wayne has extruder for small production
Wayne Machine & Die Co. developed its Yellow Jacket counter-rotating twin-screw extruder for processing powdered PVC and high density polyethylene, plus other types of plastics, for laboratory and small-production applications.
The barrel is built in three segments, including one for vacuum venting.
Each section has two universal melt taps for melt pressure or melt temperature monitoring, or the injection of gas or liquids. The drive is a 5-horsepower, alternating current flux vector. The extruder comes with a volumetric feeder.
Wayne Machine is based in Totowa, N.J.,

Flexicon rolls out bulk bag discharger
Flexicon Corp. of Bethlehem, Pa., said its bulk bag discharger, for running in-line with pneumatic conveyor systems, eliminates dust during untying and retying, discharging, collapse and removal of bulk bags.
The new bag-to-conveyor interface has two sections. The top section contains a Spout-Lock clamp ring positioned on top of a pneumatically actuated Tele-Tube telescoping tube.
Another product, the BFF bulk bag discharger with a multipurpose hood, allows automatic discharge from the bulk bags or manual emptying from sacks, drums and other containers. The bag outlet is pulled through a top-mounted valve that is closed around the spout, preventing material flow.

LSP7 unit measures temperature of film
Land Instruments International of Newtown, Pa., said its LSP7 measures temperature profiles of plastic films.
Accuracy is better than plus or minus 4° F, in the measurement range of 120-660° F.
The small footprint, 4 feet by 8 feet, fits where space is limited and minimizes heat absorption from the process being monitored. A built-in Class 2 laser defines the scan axis and the entire scan angle.
The scanner head has a wide scan angle of 80 degrees and a field of view of 100:1.

Bry-Air touts speed, ease of resin dryer
Bry-Air Inc. of Sunbury, Ohio, said its desiccant rotor-based EZ-Dry press-side dryer can process up to 600 pounds of resin an hour.
A simplified controller gives faster machine startups. The design allows for quick maintenance.
EZ-Dry also has an optional Smart-Dry microprocessor-based diagnostic controller, which monitors dewpoint, process and regeneration temperatures.

Kice offers filters, mountable dedusters
Kice Industries Inc. of Wichita, Kan., claims its 4MMA and 6MMA multi-aspirators are the first multiple dedusters specially designed to mount directly to the inlet of an injection molding machine.
They can run 50-400 pounds of material per hour. Larger-capacity units are available. The units are designed to remove fines from plastic before it is molded.
Fines can burn and create black spots and blemishes in the finished product.
Kice said that while other dedusters elsewhere in the plant can remove fines, more fines are created when transporting ``clean'' pellets to an injection press.
Kice said its VR7 filter cleans air efficiently while taking up a minimum of floor space. The unit uses pleated cartridge filters, which pack more surface area in the small space.
The quiet-running Positive Displacement Blower can handle line sizes of 3-6 inches.
Features include oversized bearings and shafts, plus an extra drive bearing to support the ``V'' belt load. Blower rotors and bodies are made of ductile cast iron from Kice's in-house foundry.
