- the pads can be fixed at regular intervals or not the along the cut contour, as it is cut.
- the application a patch 102 on the film can be produced while the carriage 52 is at stopping, or on the fly, while the carriage 52 is moving. In this last In this case, it is preferable that the speed of the carriage is relatively reduced. To avoid penalizing the cutting speed with stops or slowdowns imposed on the carriage 52, it will be possible to choose to deposit pellets at times when, in the cutting cycle, the carriage 52 is stationary in X, Y or moves at low speed (interruption of the advance at the end of the contour or for passing an angle with change of brutal direction, or slower advance when cutting a delicate contour portion, for example a notch).
- the positioning of removal device immediately behind the tool allows it to track precisely the cut contour.

- the spray nozzle 126 is located between the cutting tool (not shown in Figure 7) and the applicator 122, or in front of the cutting tool.
- Figure 8 shows a device 130 for training continuous fasteners along the edges of the film parts cut.
- the device 130 is mounted on the carriage 52 supporting the head of cutting, immediately behind the cutting tool. It includes a applicator 132 in the form of a jack whose rod carries, at its end, a heating roller 134.
- the applicator 132 is supported by the carriage 52 by means of a rotary plate 135.
- the plate 135 is controlled in rotation about its vertical axis in synchronism with the turntable carrying the cutting tool.
- Welding is carried out by pressure exerted by the roller heating 134 on the film 32 under the action of the applicator.
- a product having a function of welding promoter can be placed on the film 32.
- the deposit is carried out over a certain width on either side of the cut contour, continuously.

- this device is independent of the cutting head, which allows prevent the cutting speed from being affected by the laying or formation of attachments.
- Figures 9 and 10 show a device 140 designed to apply strips of adhesive film over the entire width of the mattress 30 covered by film 32, at the downstream end of the cutting table, before film peeling 32.
- the device 140 comprises a carriage 142 movable transversely, parallel to direction Y, along a beam 144 having a fixed position in direction X, immediately upstream of the deflector 74.
- the carriage 142 is guided by beam 144 and is engaged with a screw without end 144a parallel to the beam 144 and driven by a motor 146.
- the carriage 142 carries a clamp support 152 capable of coming into engagement laterally with the adhesive film 150 and a pressure roller 154.
- the clamp 152 is mounted on its support by being movable horizontally in direction Y between a retracted position and a gripping position, under the control of an actuator.
- the clamp 152 and the roller 154 are movable vertically between a raised position and a lowered position by being fixed to the ends of the rods of two respective actuators 152 a , 154 a .
- the adhesive film 150 passes successively between the blades of a cutting device 156 and under an applicator 158.
- the latter is formed by a roller movable vertically between a raised position and a lowered position by being fixed at the end of an actuator 158 a .
- a cycle for removing a transverse strip of adhesive film 150 includes the following operations.
- the clamp 152, the roller 154 and the applicator 158 being in the raised position, the clamp 152 unwinds the film 150, by engaging with the end thereof, by displacement of the carriage 142 in one direction (go) under the control of the motor 146.
- the clamp 152, the roller 154 and the applicator 158 are lowered to bring the adhesive film 150 into contact with the film 32.

- the projection of the welding promoter material can be performed when the carriage 162 is moved in one direction in the Y direction while welding is carried out by heating by means of radiation laser by operating the generator when moving the carriage 162 in the other direction.
- Welding can be limited to areas of intersection between the contours and the X trajectory of the radiation laser, by corresponding modulation of the radiation produced by the generator.
- the intervals between welding lines are chosen, in the same way way that the intervals between strips of adhesive film in the example previous, so that each contour is cut by at least two lines welding.
- the heating for welding can be carried out not by projection of laser radiation, but by application of a heating element, for example a heating roller carried by the carriage 162.
- a second embodiment of the invention is shown by the Figures 13 to 17. This embodiment differs from that of Figures 1 to 4 only by means of recovery of the film fragments in the downstream end area of the cutting table.
- the other elements of the installation are common to both modes of production. These common elements have the same reference and will not be described again in detail.
- the fragments of the sealing film 32 i.e. the skeleton 32 ' and the parts of film 32 "cut with the parts in the mattress 30, are taken by suction at the downstream end of the cutting table 20 at means of a movable member 200 to be released outside the path of the mattress and brought to an evacuation device 250.
- the movable member 200 shown in more detail in FIGS. 15 to 17, is in the form of a sectored annular hollow drum. It includes a hub 202, an outer wall 204 traversed by a plurality openings 206 and radial partitions 208 that extend all the way drum between the hub and the outer wall. Partitions 208 divide the drum into several sectors 210. These are among six in the example shown, but this number may be different.
- openings connect each sector with the outside, at the peripheral surface 205 of the drum, over the entire length of it.
- the openings 206 may be in the form of perforations or slots, for example circumferential slots extending over a part of the circumference of the drum, corresponding to each sector, as in the example illustrated.
- the sectors of the drum 200 are closed by annular flanges 212, 214 fixed to the drum.
- the drum 200 is mounted on an axis 216, the ends of which are engaged through plate openings 218, 220 forming bearings.
- the drum 200 is free to rotate about the axis 216.
- the evacuation device 250 comprises a tank or receptacle for reception 252 fixed to the plates 218, 220, immediately downstream of the drum 200.
- the tank 252 has a horizontal bottom wall 254, located substantially at the same level as that of the lower edges of the plates 218, 220.
- the wall 254 is folded back at its upstream end to form a rim 256 set back from the downstream generator 200b of the drum. At its downstream end, the wall 254 is folded back to form a downstream wall 258 of tank 252.
- the tank 252 is provided with side walls 260, 262. These are fixed on a tab 264 secured to the plates 218, 220 and support all of the longitudinal walls 254, 256, 258 of the tray.
- the device evacuation 250 may also include an extraction system by worm 270. This is fixed, with its drive motor 272, on one of the side walls 260 of the receiving tank 252. The fragments of sealing film recovered in the tank are extracted by the screw 270 to through an opening formed in the other side wall 262 and communicating, for example, with a chute 274.
- the plates 218, 220 supporting the drum 200 and the device 250 are pivotally mounted around a horizontal axis on supports 222, 224. These are fixed to the table frame cutting 20, on each side thereof. Pivots 226, 228 carried by the supports 222, 224 pass through openings in the plates 218, 220 located in the lower parts thereof. In this way, the whole comprising the drum 200 and the receiving tank 252, articulated on the supports 222, 224 rests by its weight on the mattress 30 coated with the film 32. As shown in FIG. 15, the lower generator 200a of the drum is lower than the lower edges of the plates 218, 220, so that the contact between the drum 200 and the mattress 30 is made only along the generator 200a.
- the rotation drive of the drum 200 with the flanges 212, 214 around the axis 216 is therefore produced by contact with the mattress 30 when this is advanced under the control of the motor 28 conveyor drive 22.
- the rotation drive of the drum 200 can be provided by a drive device, preferably disengageable, associated with an independent or driven motorization by means of the motor 28, in synchronism with the conveyor 22. Contact between the drum 200 and the mattress 30 is then not necessary, the surface of the drum can just flush with that of the mattress.
- the plate 218 which is in contact, practically free of play, with the flange 212 having two openings or lights 236, 238.
- Lines 240, 242 connect the lights 236, 238 ( Figure 15) respectively to a vacuum source and an air source under pressure (not shown).
- the slots 236 and 238 each extend along an arc with a central line located substantially on the same circumference as the centers of the openings 234 and a width substantially equal to the dimension of the openings 234.
- the slot 236 extends from a point 236 a located slightly downstream of the generator 200 a of the drum to a point 236 b located substantially at the level of the generator 200 b of the drum.
- the light 238 extends from a point 238 a located substantially at equal angular distance from the generator 200 b and from the upper generator 200 c of the drum to a point 238 b located substantially at the level of this generator 200 c .
- the angular position of the lights 236, 238 makes it possible to carry out a suction between the moment when the drum arrives near the mattress covered with the film and the moment when the drum overhangs the interior of the receiving tank 252 (the upstream wall 256 of the latter. ci being upstream of the downstream generator 200 b of the drum), and of producing a backflow after the suction until about the moment when the surface of the drum passes at the level of the upper generator 200 c .
- the fragments of film sucked up are well evacuated in the tank 252.
- the angular distance between points 236 b and 238 a of lights 236 and 238 is at least equal to the angular dimension of an opening 234, so that the same opening is not simultaneously opposite the lights 236, 238.
- L The maximum angular interval between the start of the discharge and the end of the discharge, or between the start of the suction and the end of the suction, determines the maximum angle of each sector and therefore the minimum number thereof. In practice, this minimum number is equal to 4, preferably to 5. It will also be noted that fragments of sealing film which may be of small dimensions, in certain cutting configurations, the density of the openings 206 on the surface of the drum must to be quite high. In the case of circumferential slots, as in the example illustrated, the pitch between slots is chosen between approximately 5 mm and 20 mm.
- FIGs 18 to 20 illustrate an alternative embodiment of the installation of Figures 13 to 17, the difference being in the form of realization of the evacuation device.
- the evacuation of the fragments of sealing film is made by transfer through a pipe outlet 290 between a receiving tank 280 and a recovery 292, the film fragments being for example collected in a carriage 294.
- the receiving tray 280 has a form of hood which opens at its lower part in close proximity to the surface of the drum 200.
- the opening 282 of the hood 280 extends substantially from immediately before the end of the suction zone until the end of the zone delivery (shown schematically in Figure 20).
- the fragments of sealing film collected in the hood 280 are propelled by pressurized air used for delivery, to reach the recovery device 292, through line 290.
