Two simultaneous start-ups
Last October, HERGEN has started up two Size Press equipped with Starch Application Headers. One of the projects was delivered to Brazil and the other one abroad.
The Size Press is positioned between the Pre and Post Drying sections. Its main function is to carry out a surface treatment on the paper sheet, applying a solution to its surface.
The composition and purpose of the solution may vary depending on the specific requirements of each case. In both projects delivered by HERGEN, the solution applied consists of starch, with the aim of providing greater resistance to the paper sheet.
Both projects were designed with the mission of replacing the traditional pond system with HERGEN’S SMART SIZER Film Press system. Within this starch application concept, the heads precisely dose the desired amount, transferring it to the paper sheet. It is crucial to highlight that HERGEN’S SMART SIZER solution allows the application of different quantities and products on each side of the paper web.
Furthermore, both Starch Applicators incorporate stainless Steel Structures and larger diameter Applicator Rolls. We invite you to learn more details about these two innovative projects that have been started-up.

SMART SIZER Benefits
- Fiber savings
- Savings on drying energy by adding less water to the paper
- Application with solid contents of up to 14% starch
- Greater control over the amount of starch applied, providing an excellent surface finishing to the paper sheet
- Totally independent application on each side of the paper web, allowing different applications
- Applicable on medium and high speed machines

Metering Size for Starch Application
Film Press Concept
All restrictions related to the use of the regular puddle Size Press are eliminated
High efficiency and stability even at high speeds
Starch is applied by two independent fully automated metering heads resulting in an extremely simple operation
Functioning
Two Coating Heads are fed with a starch solution which remains in continuous circulation
A starch film is applied onto Nip Rolls by Metering Grooved Rods according to process requirements
In the Nip, the starch film applied onto Rolls Surface is transferred to the sheet paper
