According to the inventive thought which forms the basis of the present invention, it is very important, especially for the skilled skater, that both skates show exactly the same behaviour, which means that they should be ground the same way with a high degree of precision. For that reason, the apparatus is according to an aspect of the invention characterised in that the clamping arrangement is arranged for clamping two skates and that the grinding wheel i5 arranged for simultaneously grinding two skates. An additional advantage is that in one operation two skates are ground, which si~~nificantly zeduces the time necessary fox grinding a pair of skates.
A favourable embodiment according to another aspect of the invention is characterised in that the appdraLuS is provided with a carriage which can be moved over the bed in a longitudinal direction and that the clamping arrangement is detachably mUUnted onto the carriage. By doing so, it i5 possible to grind one pair of skates and to finish a previously ground pair in the meantime, for example by wheLLiry Lhe freshly c~rc~und SurLac._-.es _ Mc~recwr~r, a next p<rir may already be placed in a clamping arrangement, which means that skates can be ground in a substantially conti-nuous process. In order to have a free hand to perform these parallel ac-aivitlPS, it ~s advantageous t.o provide the apparatus with additional drive means, for moving back BAR-12-01 12:49 OZ4 2566946 CA 02340607 2001-03-14 P.05 R-089 Job-860 Gee-a-Patent; 074 2566846; 12-mrt-01 18:49; Paging 5 and forth the carriage with an ar least substantially constant speed. The constant speed mozeover attributes to the quality of the result of the grinding process.
A favourable embodiment according to another aspect of the invention, by which it becomes possible to provide the skate with a previously determined radi~_~s of curvature in a longitudinal direction, is characterised in that a curved guiding strip is provided, mounted at least substantially parallel to the bed, for, steering the carriage in a cross direction. Preferably, the guiding strip is detachably mounted, such that for each type of skatE a sl.iitable guiding strip can be mounted.
A favourable embodiment according to another aspect of the invention is characterised in that the carriage is provided with at least two feelers for following the guiding strip, which feelers are preferably provided with wheels_ By providing the carriage in this way with two reference points with respect to the guiding strip, the movement of the carriage is entirely determined.

MAR-12-O1 12:49 074 2566946 CA 02340607 2001-03-14 p 06 R-099 Job-860 Get-a-Patent; 074 2566846; 12-mrt-Ot 18:49; Paging 6 A favourable realization of the inventive method is characterised in that the clamping arrangement is mounted onto a carriage and that the carriage is moved dlc.~ng the bed in a longitudinal direction with an at least substantially constant speed.
A further favourable realization is characterised in that the carriage is fed between a curved guiding stxip and the grinding wheel and that the guidir-ig SLr-ip steers the carriage in a cross direction, for grinding the skates such as to obtain a previously determined longitudinal profile.
The invention will now be further explained with a reference to the following figures, in whi~~h:
Fig. 1 schematically shows an apparar_us according to the invention in top view;
Fig. 2 ScHernatically shows a clamping arrangement in side view.
Fig_ 1 schematically shows an apparatus according to the invention in top view, which apparatus is provided with a grinding wheel 1, intended for grinding a skate iron 2 in order to give zt a previously determined radius of curvature R. Grinding wheel 1 is coupled to a motor 3, which is mounted on a slide 4, which slide 4 can be moved with a hand wheel 5 via a wire shaft 6.
During the grinding process, two skates to be ground are mounted one above the other on top of a carriage 7, which can roll across a bed consisting of two profiles 8,9 by using four small wheels 10a,10b,10c,10d. Carriage 7 is preferably driven by a second motor 11, caup3.ed to it by a chain or a toothed belt 12. It is also possible to use only MAR-12-O1 12:49 074 2566646 ~ pp340607 2001-03-14 P.O7 R-089 Job-A60 Get-a-Patent; 074 2566846; 12-mrt 01 18:50; Paging 7 motor 3, by coupling a transmission and a c-lut.ch tc~ i t for driving the chain or toothed belt 12.
In order to bring about carriage 7 to follow a trajectory in the horizontal plane with a radius of curvature R, a c_:urved guiding strip 13 is detachably mounted parallel to profiles 8,9, with the aid of two sr_rew-threaded turning knobs 19a,14b and twp transverse connections l5a,l5b, which in turn are rigidly mounted to profiles 8,9. At least one side of curved guiding strip 13 is provided with the desired radius of curvature R, for example 15 metre, and carriage 7 is provided with two small wheels 16a,16b which precisely follow the radius of curved guiding strip 13. In order to further improve this following, two spring-mountred press-on rollers l7a,l7b are mounted underneath carriage 7, which press against a side of profile 8 and bring about a constant pressure to wheels 16a,16b. This is especialJ.y important at the beginning and at the end of a longitudinal.
grinding movement because e~uring the actual grinding, ZO gri.nding wheel 1 itself will exert a sufficiently large force, which has as a result that the tolerances will be determined only by the distance between grinding wheel 1 and curved guiding strip 13.
Carriage 7 is moreover provided with tour supporting columns 18a,18b,18c,18d, onto which a clamping arrangement can be mounted during the grinding process, in such a way that the skate irons 2 ~f the skates to be ground are positioned substantially in the plane of grinding wheel 1.
In a next step, hand slide 4 is moved with the aid of wheel 5, such that grinding wheel 1 will just touch skate irons 2, after which motor 11 is started. If a pair of skates only needs some regrinding, it suffices t:o move carriage 7 back and forth a number of times, in the process of which hand wheel 5 is slightly roLaLed such as to move grinding MAR-12-Ol 12:49 074 2566846 cA 02340607 2001-03-14 P OB R-089 Job-860 Get-a-Patent; 074 2566846; 12-mrt-01 18:50; Paging 8/14 wheel 1 towards the skate irons. If more serious overhaul operations are necessary, it is advantageous to provide the apparatus with end stops which automatically reverse the direction of motor 11, and with an automatic feed, well 5 known in the art, for slightly rotating wire shaft 6 every time carriage 7 passes_ Fig. 2 schematically shows a clamping arrangement in side view, consisting of two profiles 19a,19b, of which profile lb 19h cannot be seen in t-his figure as it is situated behind profile 19a, and two transverse connections 2Ua,2Ub. The distance between profiles 19a,19b is chosen such that they can clamp the front end and the back enc~ of the skate irons 2a,2b of two skates 21a,21b. The actual clamping means consist of two fixed jaws 22a,22b wt-rich are part of profile 19a anrJ two mavahla jaws 23a,2~h whic-_h ;3t-P hi.ngPdly mountc~c3 to profile 19a. >3efore the skates are ground, they are positioned between the fixed jaws 22a,22b and the movable jaws 23a,23b and the movable jaws 23a,23b are clamped ont«
2U the skate irons 2a,2b by turning knobs 24a,29b with threaded ends which end in profile 19a. Of course, one may »se qu.i~:k-fasteners instead, which are well known in the art.
Tn an rompl-etely corresponding manner skate irons 2a,2b are mounted between the fixed jaws which are part of profile 19b and the movable jaws, after which profiles 19a,19b and skates 21a,21b are in fact united t.o one single pant.. Tn order to mount this part to carriage 7, profile 19a is provided with two cylindrical projections 26a,26b and profile 19b with two projections 27a,27b which cannot be seen in the rigure_ These projections co-operate with supporting columns 18a,18b,18c,3.8d, mounted onto carriage 7, which are for that purpose provided with a notch in which the cylindrical projections 26a,26b,27a,27b can be MAR-12-01 12:49 074 2566846 CA 02340607 2001-03-14 '.09 R-099 Job-660 .

17»ring the grinding proc-:PSS the skates irons 2a,2b are moved past one rotating grinding wheel 1, Ln such a manner that skate iron 2a contacts an upper part of a side of grinding wheel 1 and skate iron ~b contacfi.s a lower part. of the same side, which guarantees that they wil_L be ground in exactly the same manner. It remains possible though to make the end faces of fixed jaws 22a,22b and movable jaws 23a,23b slightly oblique, for slightly bevelling the skate irons 2a,2b crosswise.
After grinding, one may place the ends 2/a,2/b of profiles 19a,19b in a holding fixture, not shown here, in such a manner that the skate irons arP posh-.ioned in a hnri~.ontal plane, in which position one may easily whet the fresh ground surfaces.
The inventive method is characterised in that two skates are placed in a clamping arrangement and are simultaneously moved across a bed, past one rotating grinding wheel.
