Sizing
Portfolio of Sizing Concept for Optimal Paper Surface Finishing Quality
Surface improvement and mechanical strength are essential in markets demanding stronger, better-looking, and more printable paper.
Online sizing is standard for many P&B grades, enhancing surface quality and mechanical properties. Our size presses ensure optimal size penetration for higher strength (RCT, CMT, burst, etc.) and improved paper surface, while offering easy operation and maintenance.
Discover our two product families:
- TT SizePress
- SpeedSizer AT
Traditional Sizing Solution for Paper and Board
Reliable and cost-effective pond size press designed for low-speed applications requiring consistent surface treatment and strength enhancement.
Key features:
- Open pond application: sizing solution applied to one or both sides of the web through a horizontal or inclined nip
- Pond level control system: ensures uniform and stable distribution of the sizing agent across the sheet
- Enhanced sheet properties: improves surface strength, printability, and mechanical performance (RCT, CMT, burst resistance)
- Tailor-made design: delivers proven performance, operational efficiency, and excellent sizing results according to the specific needs of each mill
Uniform Film Application for Outstanding Paper Profiles
During sizing and coating, Voith SpeedSizer AT applies a uniform film to enhance paper characteristics, penetration, and surface coverage. Its patented design combines a carbon-fiber support beam with a stainless steel nozzle, ensuring thermal and mechanical stability for excellent CD profiles. User-friendly and reliable, SpeedSizer AT is ideal for long, steady production runs and suitable for all paper grades, including specialty papers and functional coatings.
Key features:
- Uniform film application for a wide range of different applications
- Continuous perfect profiles under all operating conditions
- Excellent runnability for long steady production runs
