Title: Tapio Waris: Innovator in Web Forming Technology

Introduction

Tapio Waris is a notable inventor based in Kyminlinna, Finland. He has made significant contributions to the field of web forming technology, holding a total of three patents. His work focuses on methods and apparatuses that enhance the efficiency and effectiveness of web formation processes.

Latest Patents

Waris's latest patents include a method and apparatus for web forming. This innovation involves a fiber suspension from a head box being fed onto a forming wire, which is part of a dewatering zone. The web being formed is subsequently led to a second dewatering zone, where an upper wire covers the web. Both wires, along with the web between them, are guided over a turning member. The design allows for the wires to bend upwards in the twin wire dewatering zone. After passing the turning member, the web continues linearly between the wires at an oblique angle. The web and the lower wire wrap around a pick-up suction roll, while the upper wire detaches from the web. Notably, the dewatering process occurs in one direction only, through the forming wire.

Another significant patent by Waris is a method and apparatus for feeding a fiber suspension onto the wire of a web former. This system utilizes a guiding device with multiple guiding channels that allow the fiber suspension to flow in parallel. These channels connect to a slice chamber that extends across the wire of the web former. A mechanism is included to separate the dilute outer part of the stock jet flowing from each channel, ensuring that local consistency variations in the lip flow across the head box are minimized.
