Valmet, Finland, has introduced FormMaster 120 for board and paper machine forming sections. The new unit improves paper and board formation through even longer strokes and higher shaking force than its predecessor. The self-balancing breast roll shaker can achieve the same strength properties with a lower basis weight, improving visual appearance of the final product.
With an axial shaking force of 120 kN—double that of the original FormMaster—the new FormMaster 120 improves strength properties and formation by optimizing fiber web structure on the wire. FormMaster 120 makes it possible to use less refining energy, minimize starch usage, and reduce calendering, while still achieving the same final quality of board and paper, Valmet notes.
"FormMaster 120 is an excellent tool for paper machine operators to optimize the properties of their board and paper. The extended stroke length, achieved with this new breast roll shaker, is key to improved formation and available with a wide range of shaking frequencies," said Pekka Hirsilä, product sales manager at Valmet.
Maintenance issues were also addressed in the design of FormMaster 120 by improving access to the main maintenance points. Customers all over the world have found FormMaster 120 safe, easy, and reliable to use and maintain.
