Supporting runner for the planing device on machines for iCe
preparation
The blade of the aforementioned planing device for prepaxa.ti.on of
the ice edge on the band cuts ahQacl of t.ne sled runner of the ice
preparation machine.
For norrtta.X, regular use, the blade ezlgagement depth is adjusted
preca_sely like the lower edge of the runner. In the case or'
regular use with a sharp b].ade, ice accretion is Effecta.ve7.y
prevented even with this minimal setting.
However, there are possible circumstances in conriec'l'.7.vn w~th
w.hxch a deeper blaCie setting ls desirable:
1. Severe ice accretion at the band edge before the first
use of the zaforemen.tioned planing device.
2. Ice accretion at the band edge caused by a la.lunr, pl.aning
blade, incorrect blaCie tietting, or excessive water
applicaY.ion.
3. Ice accretion on the entire ice surface oaused by
excessavP water applicatiori, too little blade use, or
rain, in the case of outdoor rinks.

If the blade of the edge plane is set deeper than the sled
runner, thi;s runner foJ..lows 'l;he cutting surface of the edge
plane. The latter then planes eveti deeper, because the sled
runner is its reference base_ The sled runner follows the blade
of the ice prepa.ration machine, and the entire plane works
unintentionally deep on one aide.
The minima,l setting of trie cuti;irig dnptYl to runner height is
usua].l.y su1''f.1.c1.ent, because this effectively prevents ice
accl~etion in .r.egu].ar use-
The ice accretion that has occurred according to 1. and 2.
can amount.'t.ta several millimetars, and can reach into the
surf'ace a machine width (2 m), descending from the band,
because the entire Sled, with the blade, is raised vn one
side because of the accretion.
A deep setting of the edge plane would result in 1'.he problem
described above. working off the surface that has accreted
ori the side µst therefore be started with a minimal plane
setting in =the level regiori, and take place strip by strip,
from the inside to the outside.
The problem described is effectively prevented by means of a
ama]..l aupporting runner in the inner region of the planing sled,

next t-o the cutting surface of the edge plane. This runner is
adjustable and is normally set to a level with the sled runner.
Za the 1,)lade of the edge plane is unintentionally set 'too deep,
the sled is secU.9rely held by means of the supporting runnea;, in
connection with the right g.led runner, and the ,l.eft runner does
not ;Eollow the cutting surface of the edge pJ ane. The edge pl,an.e
rlraws a clean strip having a uniform depth.
The supporting runner therefore prevents accidentally
uncontrol.led deep planing.
However, one-sided deep planing can be performed with exc llent
contr-41. If, for exaniple, the supporting runner is set 3 mm

pla.rie ia 9et slightly (-.5 mm = 0.25 revolutions) below the slcd
runner, and the main blade of the ice machina is set flush with
the sled runner, the sled runner will follow the cutting surface
of the rdge plarie until the $upporting runner supports the left
plane 3ide (3 mm).
