edges of the products. The GN800 is designed to work with minimal thicknesses of plastic materials and – in combina- tion with the common-edge system – can increase finished part output per pound (kg) of material. At NPE, the company will demonstrate a common-edge-cut tool that was developed for the GN800 thermoformer in collaboration with Gravolab, a toolmaker from Romania. GN will run a meat tray in PET/PE laminate with a 12-cavity mould while maintaining a reduced scrap rate of 18%, said Jerome Romkey, GN’s business develop- ment manager. � www.gncanada.com

filtration system and an online viscometer VIS, for the processing of 2,000lbs/h of undried and uncrystallised polyester (PET). The technology has been particularly successful


in PET sheet extrusion. As well as producing high quality rigid sheet, Gneuss now offers the option for its PET sheet extrusion lines to switch to physically foamed PET sheet by adding its new PET foam module. Foamed sheet, with a weight reduction of 50%, can be extruded with a consist- ent foam structure and mechanical properties – us- ing up to 100 % post-consumer material. Strong and consistent growth in North America has allowed the company to move forward with an expansion of its US facilities in Matthews, NC. The larger facilities offer a larger laboratory as well as more space for spare parts. � www.gneuss.com


GN Thermoforming Equipment will showcase its GN800 thermoformer for the first time in North America. It offers many standard features in order to meet manufacturers’ needs, including a forming capabil- ity of 5in above and below the sheet line, in-mould- cut capability, auto-grease, heavy-duty bearings in the toggle system, and high-efficiency solar heaters. A top priority is to improve productivity and

Com- mon-edge tooling offers the ability to form a series of square or rectangular trays in a row or multiple rows while eliminat- ing all web between the


FILM & SHEET EXTRUSION | May 2018 www.filmandsheet.com


Graham Engineering will exhibit a range of its systems for a variety of extrusion operation, including sheet system from its Welex subsidiary. The Welex Evolution sheet extrusion system – a complete production line for use in sheeting, winding, and in-line thermoforming applications – is equipped with XSL Navigator control. While the equipment on display at NPE will be for thin-gauge polypropylene, the Evolution system can be customised for widths from 36 to 90in (90 to 230cm), gauges from 0.008 to 0.125in (0.2 to 3.2mm), and throughputs up to 10,000lbs/hr (4,535kg/hr.). Monolayer or co-extrusion systems are available, with up to nine extruders. In addition to a customised roll stand, the


Evolution system can be equipped with screen changers, melt pumps, mixers, feedblocks, and dies. Additional features of the line on display include a proprietary roll-skewing mechanism for thin-gauge applications while maintaining quick roll change and electric gap adjustment under full hydraulic load without interrupting production. � www.grahamengineering.comwww.welex.com
