The flange has a surface divided into annular surface portions. The surface portions have orientation angles measured relatively to the axis of rotation of the inner roller. The orientation angles of surface portions farther from the body have greater orientation angles than the surface portions nearer to the body to mitigate adverse frictional effects between the pipe element and the flange during roll forming. ## Claims ### Claim 1 A roller for roll forming pipe elements, said roller comprising: a body rotatable about an axis; a flange extending circumferentially about said body and projecting radially outwardly therefrom relative to said axis, said flange comprising a surface having at least a first surface portion oriented angularly with respect to said axis at a first orientation angle, and a second surface portion oriented angularly with respect to said axis at a second orientation angle; wherein said body comprises an outer surface having at least one raised feature extending radially outwardly therefrom, a border between said first surface portion and said second surface portion positioned radially beyond said at least one raised feature. ### Claim 2 (depends on 1) The roller according to claim 1, wherein said body is substantially cylindrical in shape, said axis being co-axial with a longitudinal axis thereof. ### Claim 3 (depends on 1) The roller according to claim 1, wherein said flange has a circular perimeter. ### Claim 4 (depends on 1) The roller according to claim 1, wherein said first and second surface portions are contiguous with one another. ### Claim 5 (depends on 4) The roller according to claim 4, wherein each of said first and second surface portions has an annular shape. ### Claim 6 (depends on 1) The roller according to claim 1, wherein said first surface portion has an annular shape. ### Claim 7 (depends on 1) The roller according to claim 1, where said second surface portion has an annular shape. ### Claim 8 (depends on 1) The roller according to claim 1, wherein said first surface portion is positioned closer to said body than said second surface portion. ### Claim 9 (depends on 8) The roller according to claim 8, wherein said first orientation angle is from about 91° to about 93°. ### Claim 10 (depends on 8) The roller according to claim 8, wherein said first orientation angle is about 92°. ### Claim 11 (depends on 8) The roller according to claim 8, wherein said second orientation angle is from about 93° to about 96°. ### Claim 12 (depends on 8) The roller according to claim 8, wherein said second orientation angle is about 95°. ### Claim 13 (depends on 8) The roller according to claim 8, wherein said flange comprises a third surface portion positioned closer to said body than said first surface portion, said third surface portion having an orientation angle of about 90° relatively to said axis, a border between said third surface portion and said first surface portion positioned radially beyond said at least one raised feature. ### Claim 14 (depends on 1) The roller according to claim 1, wherein said body comprises an outer surface having a plurality of said raised features extending outwardly therefrom. ### Claim 15 (depends on 1) The roller according to claim 1, wherein said at least one raised feature comprises a cylindrical surface. ### Claim 16 (depends on 1) The roller according to claim 1, wherein said at least one raised feature comprises a conical surface. ### Claim 17 (depends on 1) The roller according to claim 1, comprising two of said raised features extending circumferentially about said body and positioned in spaced apart relation to one another along said axis. ### Claim 18 (depends on 1) The roller according to claim 1, wherein said at least one raised feature comprises a knurled surface facing radially outwardly relative to said axis. ### Claim 19 (depends on 1) An apparatus for roll forming pipe elements using a roller according to claim 1. ### Claim 20 A roller for roll forming pipe elements, said roller comprising: a substantially cylindrical body rotatable about an axis coaxial with a longitudinal axis thereof; a substantially circular flange extending circumferentially about said body and projecting radially outwardly therefrom relative to said axis, said flange comprising a surface having at least a first surface portion oriented angularly with respect to said axis at a first orientation angle, and a second surface portion oriented angularly with respect to said axis at a second orientation angle, said first surface portion being closer to said body than said second surface portion, said first orientation angle being less than said second orientation angle, said first and second surface portions being contiguous with one another; wherein said substantially cylindrical body comprises an outer surface having at least one raised feature extending radially outwardly therefrom, a border between said first surface portion and said second surface portion positioned radially beyond said at least one raised feature. ### Claim 21 (depends on 20) The roller according to claim 20, wherein said first orientation angle is from about 91° to about 93°. ### Claim 22 (depends on 20) The roller according to claim 20, wherein said second orientation angle is from about 93° to about 96°. ### Claim 23 (depends on 20) The roller according to claim 20, wherein said first orientation angle is about 92°. ### Claim 24 (depends on 20) The roller according to claim 20, wherein said second orientation angle is about 95°. ### Claim 25 (depends on 20) The roller according to claim 20, wherein said flange comprises a third surface portion positioned closer to said body than said first surface portion, said third surface portion having an orientation angle of about 90° relatively to said axis, said third surface portion being contiguous with said first surface portion; wherein a border between said third surface portion and said first surface portion positioned radially beyond said at least one raised feature. ### Claim 26 (depends on 25) The roller according to claim 25, wherein each of said first, second and third surface portions has an annular shape. ### Claim 27 (depends on 20) The roller according to claim 20, wherein said first surface portion has an annular shape. ### Claim 28 (depends on 20) The roller according to claim 20, where said second surface portion has an annular shape. ### Claim 29 (depends on 20) The roller according to claim 20, wherein said body comprises an outer surface having plurality of raised features extending outwardly therefrom. ### Claim 30 (depends on 20) The roller according to claim 20, comprising at least two of said raised features extending circumferentially about said body and positioned in spaced apart relation to one another along said axis. ### Claim 31 (depends on 30) The roller according to claim 30, wherein said at least two of said raised features comprise knurled surfaces facing radially outwardly relative to said axis. ### Claim 32 (depends on 20) An apparatus for roll forming pipe elements using a roller according to claim 20. ### Claim 33 A roller for roll forming pipe elements, said roller comprising: a body rotatable about an axis;
