| (54) | Method of, and device for, chamfering the edge of felt material |
| (57) The method comprises the steps of infiltrating water through the edge of the felt
material, freezing and hardening the edge of the felt material, adjusting the angle
of a cutting device, running the cutting device over the edge of the felt material
with a given inclination and cutting the edge of the felt material at a fixed angle.
The method may be carried out with a device comprising a worktable 1 to receive and
support the edge of the felt material F, a running guide 11 provided along the edge
of the felt material on the worktable, and a uniting or mounting device 20 which supports
a cutting device running along the edge of the felt material at a given angle and
slides freely on the worktable. The cutting device is provided at the front of the
felt material to cut a soaked edge of the felt material with an even chamfer at a
given angle after freezing the edge of the felt material by jetting out freezing gas
against the edge. |
