PTi's New eG-SERIES® Roll Stand

PTi's New eG-SERIES® Roll Stand

News 23.11.2021

Processing Technologies International, LLC (PTi), Aurora, IL introduces an engineered-hybrid to its robust line of G-SERIES®Configurable Roll Stands, the eG-SERIES®. Although comprised of many of the same features found within the G-SERIES® line, the eG-SERIES® roll stand's unique arrangement brings forth the most compact roll stand variant presently being offered by PTi benefiting those with very limited production floor space.

The same G-SERIES® Configurable philosophies apply to the eG-SERIES®, in which emphasis is placed on achieving high quality sheet through strict control of accurate cooling temperatures, while incorporating design features that simplify the extrusion/application process. Patented technology that remains consistent in the eG-SERIES® includes: the Linear Roll Stand Traverse, Vertical Nip Height Positioning, Chrome Roll Safety Lock-out, TRC--Transfer Roll Coating Technology.

Obtaining exact sheet thickness and proper cooling is made possible via specifically engineered design of features that adjust temperature and positioning accordingly. Hydraulic and linear bearing supported roll actuation, with motorized gap positioning, provide ease in obtaining sheet thickness requirements. High precision spherical tapered roller bearings support chrome rolls for 0.0003 - 0.0005" (3 - 5 ten thousandths) with a total indicated runout (TIR) in the stand. In addition, the standardized open loop temperature control modules, for precise roll temperature set point maintenance, allow for dedicated heat and direct inject cooling for each chrome roll zone, with a maximum 200GPM on middle chrome roll and max 130GPM on primary and secondary nip chrome rolls.

In order to achieve a compact footprint, the eG-SERIES® offers a streamlined version of the most pragmatic features within the G-SERIES®. A linear rail sub-base system with integral floor levelers assists in proper alignment and positioning of the system. Consolidated routings for water, hydraulic, air, and electrical utilities eliminates the need for rear positioned energy tracks found on the G-SERIES® configurable. Compact side car for temp station and control cabinet affixed to the frame, along with a compact conveyor arrangement and fixed height controls pendant (TITAN® PLC touch screen control interface), reduces the overall layout and corresponding space requirements.

The eG-SERIES® roll stand can be tailored to include the following equipment: Roll Skew, Servo Motorized Gap, Safety Roll Lock-outs, and eAntiSTAT™ Coater with one set of rubber covered squeegee rolls.

The unique benefits of the eG-SERIES® Roll Stands are currently being offered in J-stack or vertical down configurations, with small to medium sized rolls ranging from 36 thru 66 inch widths and roll diameters from 12 thru 30 inches. Processors requiring alternate configurations or larger roll sizes and widths can find a solution within the G-SERIES® Configurable line.
