The present invention relates to a machine for continuously reprofiling a corrugated material.
That is why support members and load distribution members are often placed between the battens and the under-roof. Such members are notably described in FR patent 2 658 848.

Referring to Figure 1, the machine according to the invention comprises a first frame 1, supporting bars 2 used as formers to reprofile a material previously corrugated 3.
The material 3 has been previously corrugated by any type of machine, this machine not being represented in Figure 1. The profile of the corrugations is also of any kind.
Referring now to Figure 2, the sheet 3 of corrugated material is supported by the bars 7 of the dryer. The material 9 which comes out of the reprofiling machine has a profile that corresponds to that of the reprofiling bars 7 and the counter-forming bars 6.
The material formed by the machine illustrated in Figures 2 and 3 will be described more precisely in reference to Figure 6.
In the example illustrated in Figure 2, the reprofiling bars 2 are fixed two by two on the endless chain 11, by means of a support 14. This allows production of the machine to be simplified.
As Figure 4 shows, each bar 2 also comprises members 19 that protrude.
Figure 4 illustrates in a more precise way how the reprofiling bars 2 are connected to the endless chain 11.
In order to be able to reprofile corrugated materials of relatively large size, the reprofiling bars are relatively long. This is why the endless chain 11 is, preferably, made up of two members 20, linked by support bars 21.
The support 14 of each reprofiling bar 2 comprises at least one member 22 movable in translation with respect to the support bar 21. Depending on the length of the reprofiling bar 2, several members 22 may be provided. The machine illustrated in Figure 4 comprises three of them for each bar 21.
Referring once again to Figure 2, the corrugating machine also comprises a slide 26 which is fixed to the first frame 1. It comprises a first part 27 that is askew, going away from the plane of the shafts 12, a second part 28 parallel to this plane and a third part 29 that is askew getting closer to this plane.
In this position, the reprofiling bar modifies the profile of the corrugated material. In the example illustrated in Figure 2, the summit of the corrugations is flattened and embossings are formed in the corrugations.
In the example illustrated in Figure 2, a part 30 of the chain 11 is parallel to the plane of the support bars 7 and the reprofiling bars 2 are fixed orthogonally to the chain. Other embodiments can be envisaged, in which the reprofiling bars are displaced, in translation, perpendicular to the plane of the support bars.
This is the purpose of the second part of the machine which will be described more precisely having regard to Figures 3 and 5.
In the example illustrated in Figure 3, the support bar 31 is common to two counter-forming bars 6, in order to reduce the cost of manufacture of the machine.
In the example represented in Figure 5, the machine comprises two movable members 32.
The cross-section of the counter-forming bars is substantially rectangular. As Figure 5 shows, each bar 6 comprises hollowed parts 47, corresponding to the protruding elements 19 of the reprofiling bars 2. The reprofiling and counter-forming bars are fixed to the machine in such a way that the protruding elements 19 can go into the hollowed parts 47 when the bars are opposite one another.
Referring once again to Figure 3, the corrugating machine also comprises at least one cam 40, rotatably driven by a shaft 41. This is rotatably mounted in a bearing 50 fixed to the block 5.
The elastic means 39 are then compressed and are in the position illustrated in Figure 5.
As described with reference to Figure 2, it is in the part 30 of the chain 11 of reprofiling bars that is parallel to the plane of the dryer bars that the reprofiling bars are in the high position, in contact with the corrugated material 3.
The distance between the reprofiling bars 2 in the high position and the counter-forming bars 6 in the low position is adjusted in such a way that the corrugated material 3 is gripped between a reprofiling bar and a counter-
forming bar. The counter-forming bars are positioned in the hollows of the corrugations of the material 3. The setting is provided by positioning the block 5 with respect to the frame 4 in an appropriate manner.
The material 9 obtained with the machine which has just been described is illustrated in Figure 6.
The flattening of the summits of the corrugations is obtained thanks to the reprofiling bars 2 and the counter-forming bars 6. The hollowed
areas 52 are formed by the protruding elements 19 which go into the hollowed parts 47.
The material illustrated in Figure 6 is more particularly intended for the making of under-roofs for flat tiles with a tenon. The distance between two hollowed areas is selected as a function of the space between the nose and the heel of the relevant flat tiles. Furthermore, the depth of the hollowed areas is selected in order to be able to receive and to maintain the tenons of these tiles.
The timber-work is firstly covered with sheets made of a material such as the one illustrated in Figure 6, the corrugations being positioned along the slope of the roof.
The reprofiling machine according to the invention allows the production of materials other than that illustrated in Figure 6. For this, it suffices to modify the reprofiling bars 2 as well as the corresponding counter-forming bars 6.
The reference numbers put in after the technical characteristics mentioned in the claims have the sole purpose of facilitating comprehension of these characteristics and do not limit their scope.
