G.F. Goodman & Son Inc. of Ivyland, Pa., is selling a new MED/1000 cutting system for medical tubing. The machine reduces the distance between feed point and cut point to minimize tubing drag, deflection and jamming. The cutter can move on a slide base 6 inches from the feed point to allow string-up of the tubing.
The knife can deliver as many as 1,000 cuts per minute.

The wrap is applied during production of coiled gas pipe in diameters of one-half inch to 11/2 inches. Traditionally, gas pipe has been supplied with retaining straps placed in several positions around the coils. But the straps can make it hard to stack the coils, Kraloy said. If the straps are cut, the pipe can suddenly uncoil.
Stretch film, in addition to solving those problems, also keeps the pipe clean at the job site.
Kraloy of Dallas said the wrap will be used on large-diameter gas pipe in the future. That pipe has been supplied in straight lengths, packed in bundles and braced with lumber. During installation, the lengths have to be joined together. But now the larger pipe is extruded in continuous lengths and rolled into coils.

Berstorff Corp. of Charlotte, N.C., claims makers of PVC films can boost production of calendering lines by 10-20 percent by retrofitting the lines with Berstorff's Air Knife.
The knife cools the PVC as it leaves the calender rolls, reducing condensation of plasticizers and boosting the grip of film to rollers as film passes through the stripper. That improved contact is what increases the speeds.
Berstorff also claims the knife, which is usually installed below the stripper unit as close as possible to the last roll, also reduces film shrinkage.

Biaxial film stretchers from T.M. Long Co. Inc. now include a new temperature programmer made of ceramic components.
Along with a rate programmer, the temperature programmer adjusts the stretchers during the stretch.
Three stretchers of different capacities orient the film. Separate heat setting/sintering frames are available for heating stretched samples to high temperatures in a separate oven without tension loss.
T.M. Long is based in Somerville, N.J.

Krauss-Maffei Corp. will show new developments in long fiber injection, gas addition, machine components and mixing heads at Polyurethanes Expo '96, to be held Oct. 20-23 in Las Vegas.
Krauss-Maffei will introduce the GBE 2000 unit, which measures nucleation levels of a mix ranging from 3-70 percent. The device has its own controller.
Krauss-Maffei also will show its automated LFI technology, first demonstrated at K'95 in Germany. The firm has applied for a patent on the machine, which uses a robot to cut and meter glass fibers directly at the mixing head during pouring. It eliminates the need for a preformed glass mat. Krauss-Maffei is based in Munich, Germany. Its U.S. operation is in Florence, Ky.
