Wet Laid Operations and Calendering
Herty provides pilot-scale product development services for important industry segments such as pulp and paper products, and the synthetic nonwovens industries. Products based at Herty have been commercialized in a range of market segments such as building materials, transportation, and energy.
We provide a fully-integrated approach to product development, from raw materials to finished product. The scope of operations includes dispersing fiber, transferring fiber slurries, mechanically modifying fiber, forming, drying and reeling webs or mats. The quantities of materials typically used during pilot-scale development can range from 50 kilograms to 10 metric tons per day. As with all of our operations, the skill and experience of our personnel ensures that all pilot-scale development projects are performed by a capable and knowledgeable staff.
Our nonwovens pilot lines are fully instrumented with in-line dry-end basis weight, ash and moisture measurement. In some configurations, Herty can provide surface treatment (aqueous and functional coatings), in-line calendaring and multi-ply forming. Calendering options include steel-on-steel and soft-nip. Our size press and calender can also be used for finishing operations on roll stock. Herty can support the development of laminating stock, facestock and labels, release liners and other specialty papers and non-woven materials. At Herty, we work with you to optimize existing products and support the development of new grades.
