3600mm 150T High Strength Corrugated Paper Testliner Paper Making Machine

This paper making machines can use waster paper,recycled paper ,tree ,bamboo ,reed ,wheat straw cotton and bagasse as raw material to make good quality craft paper, Kraft paper,corrugated paper, fluting paper ,testliner paper etc. within a capacity of around 150tons a day.

Main Production Flow of corrugated paper making machine:

Paper Machine Wire Section: 

At the inception of the paper manufacturing process lies the wire section of the paper machine. Positioned at the wet end, the headbox meticulously dispenses a homogeneous stream of aqueous stock onto the wire or forming fabric. Beneath the wire, hydrofoils adeptly extract water while enhancing fiber uniformity, facilitating the formation of a densely interwoven mat. Subsequently, the wire traverses over suction boxes, strategically positioned to evacuate moisture, thereby yielding a supple pulp mat, constituting the nascent paper web. Having traversed approximately 30-40 meters, the web undergoes rapid dehydration, reducing its water content to 75-80%, thus relinquishing its initial wet luster.

Paper Machine Press Section:

 Continuing the dehydration process, the paper web undergoes compression through a succession of nip rollers, expelling residual moisture from the pulp mat. This compression not only expels water but also fosters fiber intertwining, culminating in the formation of a compact, smooth sheet. At this juncture, the water content is diminished to a range of 45-55%.

Paper Machine Drying Section: 

Subsequently, the paper web proceeds through an enclosed chamber housing steam-heated drying cylinders, elevated to 130ºC through steam heat, ensuring the paper's attainment of 80 to 85% dryness. A wet sizing solution is judiciously applied to the paper, bestowing upon it a thin veneer of starch, augmenting stiffness and fiber cohesion. Post-sizing application, the paper advances through another array of heated drying cylinders, traversing a total of 400 meters through the dry end. During this course, the paper undergoes a significant water loss, amounting to approximately 93% of its initial content.

Paper Machine Finishing: 

For the refinement of containerboard, ensuring a smooth and lustrous surface conducive to printing, the paper undergoes a passage through a set of precision rollers, adeptly calibrated to impart a flawless texture to the paper surface.

Paper Machine Winding: 

Upon the completion of its 500-meter journey, the paper emerges from the machine, promptly wound onto a colossal jumbo reel, boasting dimensions of up to eleven meters in width and weighing up to 50 tonnes. Lifted by crane to a nearby winder, the paper is meticulously unwound and cut into smaller rolls tailored to the specifications of the discerning customer.
