Starlinger unit suited for recycling of films
Starlinger & Co. GmbH has introduced its recycling plant in a single machine, the Recostar 45 Compact, especially suited to recycling plastic films from rolls and film edge trims, or small injection molded parts.
Material is fed into the grinder using an edge trim cyclone or a reel feeder. The grinder cuts the material and feeds it directly into the extruder. The Recostar Compact, exhibited at NPE 2006, held June 19-23 in Chicago, uses discontinuous manual screen changers for most material, but the firm also offers continuous filters and safety filters.
Starlinger of Vienna, Austria, said a big advantage of the machine is that there is no preheating before extrusion. It can be fully integrated into a film line.
During NPE, Starlinger ran a Recostar 65 Universal at an open house held at its plant in the Chicago suburb of Hanover Park, Ill. The line is designed for processing hard-to-cut waste such as tapes, fibers, lumps, injection molded items, dry films and fleece. A single-shaft cutter is mounted parallel to the extruder, and both are driven independently.
The company also has a new line of Viscostar reactors to crystallize pre-washed, recycled PET flakes and convert them into food-grade pellets. The system pairs Starlinger's Recostar PET recycling machine with a Viscotec Solid State Polycondensation unit.

Pen enhances latest Gefran transmitter
A magnetic pen replaces the screwdriver to make adjustments on Gefran ISI Inc.'s redesigned M/W series of melt pressure transducers for extrusion, on display at NPE 2006.
The Autozero feature is standard on all models. The operator can offset any variations by using a magnetic pen, attached to the outside of the transmitter.
The M/W also boasts a GTP coating material applied to the sensing tip, making it extremely resistant to abrasive, corrosive chemicals and high temperatures.
Also new at NPE, the K-Series family of melt pressure transmitters for high-temperature applications, such as medical tubing and other processes that extrude high-temperature engineered resins. K transmitters use sodium potassium as the pressure transmission medium. The units are available in the same configurations as Gefran's M and W melt pressure transducer and transmitter series.
Gefran also exhibited the GFX4 and GFXtermo4 multiloop controllers for the first time. Controller features include four-loop control, self-tuning and autotuning, and a soft-start function for preheating.
Gefran is based in Winchester, Mass.

Brampton's roll cart has wireless control
Brampton Engineering Inc. of Brampton, Ontario, rolled out - literally - its new roll cart, a battery-operated cart with wireless control for removing film winders.
One cart can remove rolls from both front-to-front winders. At NPE 2006, Brampton showed a cart that can handle rolls of 40 inches in diameter with lay-flat width of 64 inches and weighing 3,000 pounds.
The carts have a scissors lift, a tilt table and built-in roll weight. A core support stand eliminates the need for operator handling of the shaft and includes both deflation and inflation of the core shaft.
Brampton said it takes just 2½ minutes to unload a roll, load a new shaft and return home or continue to the facing winder.
The company also announced a new secondary nip, with fewer rollers than earlier models, to reduce the film wrap angles and eliminate wrinkles. The nip can operate as a slitting station.
Brampton also showed a nine-layer SCD-3 streamlined coextrusion die for extruding blown film in seven to 10 layers. The modular die has stackable sections.

Sencorp to produce Asano machinery
Thermoforming machinery maker Sencorp Inc. signed a deal with Nagoya, Japan-based Asano Laboratories Co. Ltd. to push Asano's thermoforming equipment for food packaging in North America.
Sencorp will manufacture several of the Japanese company's machines.
Thermoformers from Sencorp of Hyannis, Mass., turn out packaging for consumer goods, medical and pharmaceutical products. Asano's markets include food packaging and the appliance and automotive industries.
The companies announced the deal during NPE 2006.
For food packaging, the alliance will promote Asano technology for wide-bed thermoformers and matched-metal trim presses.
The agreement covers long-term collaboration to share technology, manufacturing, sales and marketing for several Asano products in North America. Under the deal, Sencorp will provide engineering expertise to assure that Asano's thermoforming machines comply with North American requirements.
``Our agreement with Sencorp gives us immediate access to the North American market,'' said Toshihiro Takai, senior managing director of Asano Laboratories.
Asano's equipment, widely used in Japan, features high-speed integrated air valves, a grip-chain transport system that saves material, quick changeover and its Quick Response Heaters.
In addition to manufacturing, Sencorp also gets the right to integrate Asano technology into Sencorp machines.
``We are quickly working to integrate Asano's QRH into Sencorp's 2200, 2500, Amac and Gen II thermoformers,'' said Brian Urban, president and chief executive officer of Sencorp. ``The time saved turning on and off a thermoformer equipped with QRH drastically increases machine availability.''
The ability to turn the ovens on and off quickly also cuts electricity consumption, according to Urban.
Sencorp is making QRH available as an option on all its new thermoformers and as a retrofit for used machines.

Bruckner spotlights film-stretching unit
Bruckner Maschinenbau GmbH, based in Siegsdorf, Germany, displayed its Karo IV laboratory film-stretching machine at NPE 2006 in Chicago.
Used to develop new films, the Karo does monoaxial and biaxial film orientation, sold to resin suppliers, film products and universities. Three oven modules assure a realistic simulation of factory conditions.
Karo IV boasts high stretching ratios, up to 10 by 10.
Bruckner's U.S. unit, Bruckner Inc., is in Greenville, S.C.
