- Figure 13 is a schematic elevational view of a third embodiment of a machine according to the invention.
- FIG. 1 represents a machine for varnishing the upper face of skis, for example skis belonging to a ski rental company.
- This machine comprises a fixed frame 1 composed of a sole 2 and a vertical flange 3. It comprises a container 4, of rectangular shape, which is placed on the sole 2.
- This container has a relatively small volume to avoid clutter too large, and it may contain a bath of liquid, cold-polymerizable synthetic resin, for example polyurethane resin which is mixed with a hardener.
- An advantage of such a machine is that it can operate with a relatively small amount of varnish in the tank, for example an amount less than 1 liter.
- the machine comprises a varnishing roller 5 which is wedged on a shaft 6, the roller 5 and the shaft 6 being rotated by a gearmotor not shown.
- the shaft 6 is supported by two inclined arms 7 which are located on either side of the tank and which are connected by a transverse axis 8.
- the roller 5 carries an elastomeric coating 9.
- the elastomeric coating 9 must have a relatively low hardness, for example between 30 and 70 of the Shore hardness scale, and a thickness sufficient to match the transverse profile of the surface to be varnished.
- the skis are engaged manually on the varnishing roller 5 and are pushed from right to left, and the varnishing roller 5 is rotated clockwise, from so that the upper part of the roller on which the upper face of the ski is pressed moves in the opposite direction to the direction of movement of the ski, which leads to a regular application of the varnish on the ski.
- the skis are presented one by one or in pairs, the upper face of the ski being directed downwards.
- FIGS 3 to 5 show an example in which the tip of the skis is engaged first.
- the varnishing roller 5 can have a width sufficient to receive two skis at the same time, or a monoski whose width can reach 250 mm, or a board whose width can reach 400 mm.
- Figures 1 and 2 show a machine which has a rule 11, which is parallel to the generators of the roller, and which extends over the entire width thereof.
- the rule 11 is placed slightly below the upper generator 50 of said roller 5 and in front thereof in the direction of movement of the upper part of said roller. In other words, the rule 11 is placed between the upper generator 50 and the surface of the varnish, upstream of the upper generator 50 in the direction of rotation of the roller. In the case of FIGS. 1 and 2, the roller rotates clockwise and the rule 11 is placed to the left of the upper generator 50. If the roller rotates anticlockwise, rule 11 would be placed to the right of the upper generator.
- the rule 11 is carried by two inclined arms 12, the lower ends of which are fixed to the two arms 7, so that the rule is substantially fixed relative to the frame and to the varnishing roller.
- the rule 11 is pivotally mounted on the arms 12 and it is locked in a position determined by nuts 13.
- the machine further comprises a wiping means serving to stretch the resin film after it has been applied to the ski.
- the wiping means is a brush 14.
- the brush 14 is parallel to the generatrices of the varnishing roller and has a width slightly greater than that of the roller. It is located downstream of the roller in the direction of movement of the skis, so that they pass over the brush after being passed over the roller.
- a problem to be solved was to design a brush which disappears to let the ski tip pass, and which then follows this tip.
- the brush 14 is supported by two arms 15 which are articulated on shaft 6 of the roller.
- a return spring 16, fixed to the flange 3, tends to return these two arms upwards to a substantially horizontal position.
- the brush 14 is mounted on a transverse axis 17 which is articulated on the two arms 15.
- a return spring 18 tends to rotate the brush 14 around the axis 17, to an extreme high position, shown in FIG. 3, in which it is retained by a stop 140.
- the brush 14 is cut in a bevel so that the height of the bristles increases in the direction of progression of the ski.
- the base of the brush on which the bristles are fixed is pierced with holes which allow the flow of varnish which falls back into the tank 4.
- FIGS 3 to 5 explain the operation of the machine according to Figures 1 and 2.
- the skis are pushed manually from right to left, the tip forward and the top face down.
- FIG. 3 represents the start of the passage of a ski 26. After passing over the roller 5, the tip 26a abuts against the bevelled upper face of the brush 14 which is in the high position, substantially at the same level as the generator superior 50 of skiing.
- the brush 14 pivots around the axis 17 and the arms 15 pivot around the axis 6, so that the spatula can engage on the brush which disappears downwards, and the brush automatically retains a substantially inclination constant with respect to the surface to be varnished.
- the ski is presented on the roller in a slightly inclined position.
- FIG. 4 represents a more advanced stage during which the ski 26 is horizontal and rests on the upper generatrix 50 of the roller and the spatula 26a passes over the brush. Thanks to the action of the return springs 16 and 18 which balance the thrust of the spatula, the brush 14 follows the surface thereof.
- FIG. 5 represents the subsequent stage in which the upper face of the ski passes over the upper generatrix 50 of the roller and then over the brush 14.
- FIGS. 6 and 7 respectively represent an elevation view and a front view of the membrane wiper, when the membrane has been removed.
- This wiper comprises a rigid base 20 carrying a b loc 21 made of cellular foam, the upper face 21a of which is beveled.
- the base 20 also carries two vertical rods 22a which are each engaged in a hole in the base, so that they can slide therein to adjust the membrane tension and give it an appropriate shape.
- the width of the block 21 is substantially equal to that of the varnishing roller.
- FIGS. 8 and 9 respectively represent an elevation view and a front view of a complete wiper and which is coated with its flexible elastomer membrane 23 which forms a cap and envelops the top as well as the lateral faces and the front faces and rear of the block 21.
- the membrane 23 also surrounds the rods 22 and 22a by resting on the top thereof and it is stretched transversely between the two rods.
- the rods 22 and 22a have a spacing greater than the width of the surface to be varnished.
- the ski during varnishing leans against the top of the flexible membrane 23 which follows the transverse shape of the ski by resting on the foam block 21 which keeps the membrane in contact with the ski.
- FIG 12 shows a third embodiment of a wiper means according to the invention.
- the wiper 47 comprises a crosspiece 40, connecting the two first ends of the arms such as the arm 15, the second ends of which are articulated on the axis 6.
- the crosspiece 40 carries two uprights 41 and 42, the upper end of which comprises slots 43 and 44 respectively.
- the slots 43 and 44 are intended to receive and pierce the ends of a strip 45 or flat elastomer membrane.
- Pinch means are provided for retaining the strip 45 in the slots after its introduction.
- the wiper means according to the invention does not need to be orientable at the end of the arms 15, unlike the brush 14. Maintaining the wiper can then be ensured in accordance with in the embodiment of FIG. 11.
- the wiper can be of the strip or flat membrane type like the wiper 47, or of the membrane type like the wiper 19.
- the wiper 47 is integral with the ends of the arms 15.
- the uprights such as the upright 41 are shaped to place the edge 46 of the wiper in a position relatively close to the upper generator 50 of the cylinder 5.
- a particularly advantageous assembly has also been shown for ensuring the return of the wiper upwards, against the pressure exerted by the ski.
- the arms 15 are subjected to rotation by the shaft 6 itself, by providing friction means 60 between the arms 15 and the shaft, a stop 51 limiting the rotation of the arms 15 at the end of the stroke. high as shown in the figure.
- the spring 16 is thus eliminated.
- the friction drive 60 of known type, simultaneously provides damping favorable to the elimination of rebounds or vibrations. This results in a more uniform distribution of the varnish on the surface to be varnished, the pressure force of the wiper being remarkably constant on the ski.
- the friction means 60 could be replaced by counterweight means, urging the arms 15 upwards.
- the rule 11 is carried by arms 12 fixed relative to the arms 7.
- F igure 10 shows an elevation view of an embodiment of an automatic machine according to the invention, which applies a varnish of polymerizable resin on the upper face of the skis without requiring the presence of an operator.
- This machine comprises a fixed support 24 which has a longitudinal profile turned downwards conforming to the shape of the sole of a ski whose tip is at the front.
- the support 24 is equipped with means allowing a ski 26 to be fixed therein in the inverted position, that is to say the sole being turned upwards.
- the support 24 has transverse rollers
- a machine according to FIG. 10 further comprises a tank 27 containing a bath of cold polymerizable resin mixed with a hardener, and it also comprises a varnishing roller 28 similar to the roller 5.
- Two arms 29 are articulated on the shaft 30 of the roller and a brush 31 is mounted articulated on a transverse axis 32 carried by the two arms 29.
- the brush 31 is replaced by a wiper such as the wiper 19 or the wiper 47
- the wiper can be mounted fixed at the end of the arms 29, without articulation on the axis 32.
- Return springs not shown entent tend to rotate the two arms 29 and the brush or wiper 31 clockwise.
- the relative arrangement of the roller 28, the arms 29 and the brush 31 is similar to that of the same elements represented in FIG. 1.
- the roller 28 is driven in rotation on the shaft 30 by a motor, and it soaks in the bath contained in the tank 27.
- the shaft 30 is mounted on two vertical rods 33 placed on either side of the tank 27.
- the rods 33 belong to two elastic jacks 34 which are spring ins 35 or air mattresses which push the rod upwards .
- Each of the jacks 35 has rollers 36 which roll between two rails 37 parallel to the ski.
- the machine comprises means for moving the jacks along the rails 37 from the left to the right. During this movement, the upper face of the ski, facing down, rubs against the periphery of the varnishing roller 28, which has the effect of applying a layer of varnish to the upper face of the ski.
- the revarnishing of skis makes it possible to stick labels on the upper face of these in a material which resists varnish, for example polyurethane. These labels are then covered by the layer of transparent varnish which protects them while making it possible to read the inscriptions which they carry.
- These labels may bear a legible code allowing each ski to be identified, a bar code, the name of the ski rental company, the category of skis, advertising notices, etc. . .
- FIG. 13 represents an embodiment according to the invention in which the ski 26 is driven in translation by pinching between the varnishing roller 5 and a driving belt 52.
- the carpet 52 is in abutment on the lower face of the ski facing the top, and are driven by two rollers 53 and 54.
- the roller 53 pivots on a movable support 55, the support 55 being movable in vertical translation allowing its spacing and its approach relative to the varnishing roller 5.
- the roller 54 journals around 'a fixed axis 56.
- This arrangement allows mechanical driving of the ski, while providing space for the tip 26a.
- the mechanical drive improves the regularity of the speed of movement of the ski on the varnishing roller 5, and thus tends to improve the regularity of the deposit of varnish on the ski.
