PRESS SECTION

Overmade Presses family covers all paper and tissue grades and production speeds. Single and double felted layouts are available with Suction Press roll, plain press rolls and Over XL shoe press or crown controlled press rolls.

Our Paper & Board Presses have single and double felted layouts and they are are available with Suction Press roll, plain press rolls and Over XL shoe press or crown controlled press rolls:

• OVER Press-I: compact no-draw, triple nip press. Ideal for rebuilds and modernizations of the wet end area.
• OVER Press-II:  a combination suction pick-up/press roll, generating two nips. This configuration is one of the most successful press designs, ensuring great water removal capacity and optimum sheet non-two-sides
• OVER Press-III: modern design of no-draw, three-nip press, specifically conceived for high speed production (above 1200 mpm) of newsprint and nowadays used for light packaging grades
• OVER Press-IV: the third nip is followed by a fourth nip, with the main purpose of improving the "non-two-sides"
• OVER Press-V: modern press design for applications on high-speed on white top and liner grades where top side smoothness is a must
• OVER Press-VI: press configuration for application on high-quality communication grades, such as bond papers and art paper, where the absence of shadow marking is mandatory requirement
• OVER Press-HL/HLD: long nip press designed for application on linerboard and cardboard grades. The press (single or tandem layout) consists of two large-diameter rolls providing a very long nip and high press impulse.
• OVER Press-XL: shoe-type press, designed for application on a variety of paper and board grades. It consists in one solid roll and one flexible roll, provided with a flexible polyurethane shell conforming around the shoe element. The press has a shoe length from 250 to 290 mm, depending on applications, and is designed for nip loads in the range from 600 to 1,200 KN/m, depending on the particular paper grade you want to obtain

The press section for TISSUE GRADES consists of one or two press rolls nipped against the Yankee dryer. The big diameter of the rolls and the soft cover ensure high bulk and softness of the paper, while the combination of driling and blind drilling, with a silent pattern geometry, allow the best dewatering avoiding shadows marking, vibrations and noise. The configuration with one single press roll, "suction" type, is chosen in order to obtain the highest paper bulk, reducing also the initial investment; the configuration with a suction roll followed by a blind drilled roll is instead chosen to reduce the drying energy costs and increase the production capacity. The press rolls loading is carried out by a hydro-pneumatic system, to avoid vibrations. Design solutions completely cantilevered are available, to reduce felt change time.
