Device for creating automatic handsheets.

The main advantages include:

• The handsheet shape is rectangular.
• Sheet lookthrough is excellent.
• The fiber orientation is dependent on jet to wire speed ratio (both are adjustable); therefore, it is possible to obtain orientated handsheets.
• The retention of fillers, chemicals or dyes is excellent.
• The distribution of elements in the sheet thickness is similar to a PM produced sheets.
• A large range of fiber types can be used; short or long fibers, synthetic fibers (non hydrophobia), recycled fibers, nonwood fibers, etc.
• A large range of basis weight sheets can be made from fine papers to board.
• It is easy to make bijet or multi jet sheets with excellent adhesion between the various grades.
• Rectangular handsheets can be pressed, dried, calendared, coated or sized, and tested as normal paper.
