(57) The invention relates to a device for forming a curved snow surface. The device (1)
comprises an arm (13) which has at least two subarms (15, 17), which are hingedly
interconnected for relative angling thereof in one plane, a connecting means (5) fixed
to one end (23) of the arm and adapted to connect the device to a piste vehicle, a
holder (43) which is hingedly fixed to the other end (31) of the arm for angling,
in said plane, the holder in relation to the arm, and a working roll (35) which is
rotatably suspended from the holder and is rotatable about its own axis which is parallel
with said plane. The circumferential surface of the working roll is provided with
working projections (43) which are designed and arranged in such manner that their
tips, as the working roll rotates, touch a fictitious, spool-shaped surface surrounding
the roll.
The invention also concerns a method and a working roll for forming a curved snow
surface.
