Crosshead dies take any extruder layout
Guill Tool and Engineering Co. Inc. introduced a line of THHN crosshead dies.
The coextrusion dies accept any extruder layout. By changing one component, the die can be operated as a single extrusion crosshead.
The West Warwick, R.I., company said the THHN crossheads also feature an integral heating system, providing consistent heat throughout the crosshead.

Patt offering line of screen changers
Patt Filtration Inc. has introduced a new line of polymer screen changers.
The Rotary III Constant Pressure Continuous Flow Filtration system, with the LL line of screen changers, is designed for laboratory use or in production to sample the melt.
The screen changer can be equipped with customized, interchangeable disks. The number of cavities machined into each disk can be changed, depending on the resin.
For example, when the material cost is high, the disk can be made thin and each cavity shallow, to minimize the amount of material retained in each cavity.
Throughputs range from 4-60 pounds an hour.
The company is based in St. Eustache, Quebec.

New Gala pelletizer doubles past output
Gala Industries Inc. of Eagle Rock, Va., said its Model G2 underwater pelletizer can turn out 30,000 pounds an hour — more than double the rate of earlier Gala pelletizers.
The company has added several features to make the equipment easier to use and more automated. ``Push-button'' clamping uses pneumatic power clamps for holding the pelletizer to the cutting chamber. Once the pelletizer is in the ``rolled-in'' position, the operator presses a button to actuate the clamping mechanism.
An ultrasonic proximity sensor monitors cutter-blade wear, and the shaft automatically adjusts to compensate for wear.

Small Wayne pullers deliver full-size traits
A new line of small pullers from Wayne Machine & Die Co. is scaled down from full-sized production units, unlike typical small pullers that are merely laboratory-grade models, according to the Totowa, N.J., company.
They come with flux-vector or servo-driven motors for smooth operation. Depending on the application, the pullers use smooth-gear drive or direct drive.
The pullers are designed for handling parts such as medical and industrial tubing, profiles, rods, wire, fiber-optic sheathing, monofilament and film.

Vertical blenders available from Ross
Charles Ross and Son Co. is selling 1-cubic-foot vertical blenders.
The vacuum-operated blender has a jacketed vessel wall for heating or cooling. A high-speed chopper at the bottom of the side wall reduces agglomerated material or controls particle size.
An automatic raising and lowering mechanism enhances the charging and discharging of raw materials.
Charles Ross and Son is based in Hauppauge, N.Y.
