Based on the experience gained over many years, Cannon Viking’s LayDown Master is a distribution device which has been inspired by the CarDio® gatebar. It is aimed at slabstock producers using a conventional Liquid Laydown or Maxfoam Trough machines. The LayDown Master has been specifically developed and made available as a kit for evenly distributing the liquid PU across the width of the foaming conveyor before reaction, requiring less modifications to the existing hardware and suitable to be (retro)fitted to virtually all existing foam production lines.
“The advantages of the LayDown Master are numerous,” says Richard Doublet-Stewart, Regional Sales Manager at Cannon Viking. “The technology avoids the use of a traversing mixing head, whilst providing uniform foam laydown across the whole width of the conveyor, delivering a more regular cell structure across the block. The LayDown Master is especially suitable for highly reactive foam grades, such as MDI, Viscos and HR foams. It produces optimum quality foams due to liquid laydown by avoiding pinholes and build-up, typically seen with Maxfoam trough technology.”
As the Laydown Master is available as a kit, it requires a short installation time on existing production lines, ensuring only a minimal impact on the production and machinery. It is suitable for low-pressure, partial high-pressure and high-pressure technologies, and allows for a quick change of grade and colour, shortening the transition phase between foam grades, reducing the amount of scrap foam and thus saving valuable raw materials.
The LayDown Master features a slot that is wide enough to allow for the use of very viscous formulations and solid fillers, which are key to ensure consistent quality for the foam standards. The slot can be easily adjusted between different foam grades by inserting spacers, reducing downtime to the absolute minimum.
Cannon Viking offers several technologies aimed at foam producers with continuous and discontinuous block foaming methods. Under the CarDio® brand this includes complete production lines as well as conversion kits for existing lines for using liquid CO2 expansion technology, while the new LayDown Master is aimed at new and existing lines with Liquid Laydown technology. Together with its foam block size and profile control technologies, Cannon Viking now has a full range of equipment available to cover all possible PU slabstock foam market needs.
