November 28, 2011 - Processing Technologies International (PTi), a leading global manufacturer of high-performance
sheet extrusion machinery, has been granted a U.S. patent for its linear bearing
mounted roll stand which provides high precision and repeatability along with
faster installation. The G-Series roll stand is a key feature on PTi's
Globaline® series of sheet
extrusion systems which focus on flexibility, allowing processors to
efficiently run a range of production outputs.
"This is an important technological development that significantly reduces installation time and ensures high precision and repeatability of the sheet extrusion system," said James Johnson, PTi's Senior Vice President of Applications and Technology.
The patent (US 8,021,140) was recently granted
to PTi president Dana Hanson and colleagues Mitchell Gritzner and Ryan Leopold.
The patented design offers distinct advantages over competitive units where the
cooling roll moves as a unit and the frame is mounted either on 'V" wheels or
"keyed" wheels with the matching track design. Initial installation for these
competing units is time-consuming with track leveling and grouting requiring 80
work hours to complete.
In comparison, the patented G-Series
roll stand has cooling rolls that are mounted on a linear motion guide track.
Instead of moving the entire frame, only the cooling rolls move when access to
the die network is required. Movement on the linear motion guide track is
extremely precise and repeatable, ensuring exact tracking and precise sheet
Initial installation of the G-Series
roll stand takes only approximately 16 work hours. Leveling of the frame does
not require track installation but instead uses leveling pads which are pinned
to the floor.
Another inherent advantage of the G-Series
design is the utility line for air, water, and electrical connections which are
located beneath the frame deck plate. This placement yields unimpeded access to
all key components for serviceability and maintenance.
The G-Series roll stand requires less
space and fits in tighter confines because the frame does not move when the
cooling rolls traverse back and forth.
The G-Series roll stand is a key
feature on PTi's Globaline® Series
of sheet extrusion systems and is also sold separately.
