For example, the development goal for the UniFilm roll cover was to substantially extend the metering rod service life.
The new UniFilm cover for applicator rolls impresses with its high abrasion resistance and longer metering rod service life thanks to micro-lubrication.
After the sheet is pre-calendered, it is film-coated in a metering rod
BASF Plastics' Ultraform acetal copolymer is used to mold the ball valve and two components--the metering rod
and sensor disk.
Hubble's mirror makers used laser light and the precision measuring tool -- called a metering rod
-- to determine how far apart to space two components of the grinding guide, a device known as the reflective null corrector (SN: 7/21/90, p.
The components are then forced by metering rods
directly into a disposable static mixer.
Depending on the metering rods
selected, the valve is capable of dispensing 5 cc of material down to 0.
North Canton, Ohio, uses positive-displacement metering rods
and balanced inlet/outlet spool valves, which are said to provide [+ or -]1% ratio and shot-size control.
