Abstract
An element for a co-rotating twin screw processor, the element having a lead ‘L’ and at least one continuous flight helically formed thereon and, wherein the flight transforms at least once from a first non-integer lobe flight into a second non-integer lobe flight in a fraction of the lead ‘L’ and transforms back to the first non-integer lobe flight in a fraction of the lead ‘L’.

An element for a co-rotating twin screw processor, the element having a lead ‘L’ and at least one continuous flight helically formed thereon and, wherein the flight transforms at least once from a first non-integer lobe flight into a second non-integer lobe flight in a first fraction of the lead ‘L’ and transforms back to the first non-integer lobe flight in a second fraction of the lead ‘L’.
An element for a co-rotating twin screw processor, the element having a lead ‘L’ and at least one continuous flight helically formed thereon and, wherein the flight transforms at least once from a first non-integer lobe flight into a second non-integer lobe flight in a first fraction of the lead ‘L’ and transforms from the second non-integer lobe flight to a third non-integer lobe flight in a second fraction of the lead ‘L’.
A twin screw processor comprising:
- a housing having at least two cylindrical housing bores, each housing bore having an axis disposed parallel to the other axis;
- at least a first screw shaft and a second screw shaft being disposed in the first and second housing bores;
- the first and second screw shaft being provided with elements defining a mixing zone;
- wherein at least one element has a lead ‘L’ and at least one continuous flight helically formed thereon and the flight transforms at least once from a first non-integer lobe flight into a second non-integer lobe flight in a first fraction of the lead ‘L’ and transforms back to the first non-integer lobe flight in a second fraction of the lead ‘L’.
