An anvil roll (2000, 3000), for treating a web material, preferably heat embossing, more preferably for ultrasonic bonding, - exhibiting a cylindrical outer support surface, an anvil roll axis (2005, 3005), a radius, - comprising - a plurality of arcs (1, 1',...) protruding outwardly of said cylindrical outer base surface, - said arcs (1, 1',...) being formed by an arc wire, preferably metal wire, preferably essentially identical for said plurality of arcs (1, 1',...), and more preferably a single wire forming said plurality of arcs, - said arcs (1, 1',...) comprising o an upper free arc portion oriented outwardly of said support surface ▪ such that the surface of said arc wire tapers down from its tip as the most outwardly positioned point of said free arc portion towards said anvil roll support surface in all directions, ∘ a first and a second side arc portion, wherein said plurality of arcs (1, 1',...) is arranged such that ∘ an arc tip line connecting said most outwardly positioned points of said upper arc portions defines the x-direction of said arcs (1, 1',...), wherein each arc (1, 1',...) exhibits a length extension (x H) along x-direction and an arc height H 0 extending perpendicularly to said support surface and to said length extension x H, characterized in that said anvil roll (2000, 3000) further comprises a pinching device (51, 52, 2010, 2020, 3010, 3020, 3090) comprising at least two compression jaws positioned radially outwardly of said support surface, and adapted to apply a transverse compression force along a y-direction perpendicular to said length and height extension of said arcs (1, 1',...) at a pinch point (41, 42) in said side portions of said arcs (1, 1',...), thereby essentially preventing movement of said arc wire in said pinch point (41, 42), and said pinching device (51, 52, 2010, 2020, 3010, 3020, 3090) further being adapted to transmit z-directional forces applied to said upper arc portion and via said first or second side portion (23, 27) through the pinch point (41, 42) to said support surface. -
