Abstract (en)
[origin: EP0830897A1] The armour plating comprises a number of pins (11) with the mushroom configuration and which by its head (12) protrudes outwards from the roller body (10), and by its shank (13) is let into the corresponding recess or hole in the roller body. A free space (14) remains between the bottom of the hole and lower shank end. The seating face of the pin head lies flush with the roller surface or is countersunk in a recess (15).
