Round Up
The Round Up process removes the outer layer from the BTT and prepares the resultant core for subsequent manufacturing operations. The outer layer of the BTT is removed as a single, continuous length of material that is subsequently dewatered or dried by the dewatering process. The round up process produces a strong, heavy board material that can be manufactured into an array of different products, characterised by their unique appearance and useful physical properties.
The material can be laminated during manufacture to produce various plies for structural as well as decorative applications.
Core Veneer
After the outer layer is removed from the BTT the resultant core is transferred to the core veneer process. The core veneer process is essentially a more precise version of the round up process in that it cuts a finer, continuous length of material until the remaining core (or cigar) is approximately 15mm in diameter.
As for the round up process, the Core Veneer manufacturing process uses a type of spindle-less lathe to undertake the operation of reducing the core cylinder into a continuous length of material of consistent thickness. The core lathe differs from the round up lathe only in that the cutting process is undertaken with a higher degree of accuracy and the resultant veneer is cut thinner and in a manner to maximize the length of continuous material.
The core veneer is then transferred to the drying or dewatering process and dried to a predetermined humidity level before sheeting and palletisation. The resultant product has a wide array of applications as described in the Products section of this website.
As for round up material, the core veneer material can be laminated during manufacture to provide various plies where required.

Dewatering (Drying) Process
The dewatering process is similar for both the core and round up process and uses a method not unlike that used for drying paper. In essence, the dewatering process relies on the combination of the following variables:
Conveyor Belt Material
Speed
Temperature
Pressure
The dewatering process uses a combination of these variables to obtain a suitable material quality whilst minimising the amount of energy expended during the process. Wherever possible, energy is reused at different points in the dewatering process and all water produced is collected and used for irrigation and other purposes.
Once the Papyrus material has been dried to the required level, the material is sheeted to predetermined dimensions and palletized for consignment to the Customer.
