As the rolls build larger in diameter, the footprint (area) of the nip between the winding roll and the pressure roll
Kadant offers a range of coatings for its blades that address specific requirements of both high quality consumer grades and 100% recycle away-from-home grades." Vandoros continues, "The new CeraEdge creping blades fit nicely in Kadant's product portfolio for tissue producers, which includes Yankee doctor systems and holders, spray booms, suction pressure roll
doctors, steam and condensate equipment and technical service."
The new unit features heated Main Cylinder with maximum pressure of 9 bars, digital display of Pressure Roll

Gather your thoughts and let the pressure roll
Later this year, the high pressure roll
is to be tested on iron ore in North America with the installation of a 1,350 kW unit at the Empire iron ore operation in northern Michigan.
The second part includes an unwinder, a laminator where the molten film is delivered to a point of contact between a pressure roll
over which the substrate passes, a cooling roll, and the rewinder.
However, when the pressure roll
is driven to control the web's tension, then the torque induced through the center of the roll can be independently controlled to adjust the winding roll's hardness profile.
The pressure roll
sticks the sheet to the Yankee with the aid of coating spray applied at much higher amounts than used on conventional dry crepe machines.
The cameras look at the wire against the black rubber background on the #3 roll between the pressure roll
and the 2:3 roll nip.
Also late last year, Dolci Extrusion in Milan, Italy, delivered its first Contrawind 2000 winder for stretch film, which uses a rotating cutting arm with an opposing pressure roll
to put tension on the stretchy web and avoid making a flap of film at the start of a new roll.
