MarquipWardUnited has recently introduced the new TwinCut feature to their sheeter product line for twin synchronous knife Sheeters. The TwinCut is offered on the SheetWizard, which was introduced in 2007 and has since been the bestselling dual rotary sheeter in its class.
MarquipWardUnited Sheeters offer flexible configurations that have been installed in mills cutting both paper and board; folding carton plants where sheets are stacked central to the plastic pallet feeding direct to the press; and to converters with products as diverse as 24 gsm silicone paper to 800 gsm board. TwinCut takes this already flexible Sheeting platform to a whole new level.
The growth of digital size sheeting has presented a problem for converters and mills worldwide. Digital sheet sizes have diverged from the standardized formats such as A4 or A3 or 8½” x 11”, and have instead seen a growth of sizes between A4 and GTO formats. Customers with traditional cut size lines are unable to handle these flexible formats. Customers with traditional folio size Sheeters were presented with the choice of either running finished size at very low speeds or sheeting double or quadruple size and guillotining afterwards. Neither option is efficient or cost effective.
TwinCut allows mills and converters to sheet from A4 or 8½” x 11” up to large folio format on the same machine. On cut size and digital production, the sheeter operates in the production range of 18,000 sheets per minute based on a five web, five pocket set up. On the same machine running a typical five web, 80 gsm sheet 720 mm x 1000 mm a typical output exceeding four tonnes per hour is achievable.
The SheetWizard with TwinCut can be configured to produce sheet in palletized stacks or in reams. When ream production is required a complete system giving wrapped reams in cartons automatically palletized and wrapped can be supplied.
MarquipWardUnited has six sheeters currently operating with the two knives per drum technology; including three at a major paper producer in Korea.
The SheetWizard with TwinCut is positioned to be a market leader offering high quality sheeting for paper and board delivered in the form required by today’s efficiency driven converters and mills.
