SUPPORTING RUNNER FOR THE PLANING DEVICE ON MACHINES FOR ICE PREPARATION

PATIN DE SUPPORT POUR DISPOSITIF D'APLANISSAGE DE MACHINES DE PREPARATION DE LA GLACE

English Abstract

If the blade of the chamfer plane of ice preparation equipment is set to a
lower depth than the carriage runner, the latter follows the cutting surface
of the chamfer plane. The latter then planes to a lower depth as the carriage
runner is its reference base. The carriage runner follows the blade of the ice
preparation equipment and the planing action of the entire plane is
unintentionally deep on one side. Said problem is effectively prevented by a
small supporting runner that is located in the interior of the plane carriage,
adjacent to the cutting surface of the chamfer plane. Said runner can be
adjusted and is usually set to lie level with the carriage runner. If the
blade of the chamfer plane is inadvertently set to a depth that is too low,
the carriage is held secure by the supporting runner in conjunction with the
right-hand carriage runner and the left-hand runner does not follow the
cutting surface of the chamfer plane. The latter thus produces a cleanly
planed strip with a uniform depth.

French Abstract

Lorsque la lame d'un rabot de bords d'une machine de traitement de glace est réglée plus bas que le patin de chariot, le patin suit la surface de coupe du rabot de bords. Celui-ci effectue alors un rabotage plus profond du fait que le patin de chariot constitue sa base de référence. Le patin de chariot suit la lame de la machine de traitement de glace et l'ensemble du rabot effectue un rabotage plus profond que souhaité. La réduction de la taille du patin support à l'intérieur du chariot de rabot, à côté de la surface de coupe du rabot de bords, permet d'éliminer efficacement ce problème. Ledit patin est réglable et est normalement réglé dans un plan avec le patin de chariot. Lorsque la lame du patin de chariot est réglée trop bas par inadvertance, le chariot est sécurisé par le patin support en connexion avec le patin de chariot droit, et le patin gauche ne suit pas la surface de coupe du rabot de bords. Le rabot de bords crée un tracé net, de profondeur constante.

Claims

Claim

1. Supporting runner for supporting the left side of the

planing sled of the ice preparation machine, the reference
base for the edge plane, so that this base is not influenced.
by the plane cut, characterized in that

this runner is attached at the planing sled or at the
console of the edge plane in such a manner that it holds the
planing sled in a stable position, together with the right
runner of the latter, and the runner lies on the ice next to
the cutting surface of the edge plane.


2. Supporting runner according to claim 1, characterized in
that

it is adjustable in height and can be locked in place.

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,

The supporting runner therefore prevents accidentally
