Definitions

  • the present invention relates to a lapper spreader for transforming by folding a web into a web.
  • FR - B - 2 553 102 such a machine in which a veil, coming from a carding machine, is first transported by a first mat, called front mat, to a pinch zone where it is held between the first and a second mat and transported to an exit cart.
  • the back-and-forth movement of the exit carriage above a receiving apron causes a deposition of the veil which it delivers, by alternating folds, in accordion, on the apron.
  • the apron moves in a direction parallel to the axes of the guide rollers carried by the output carriage, the successive folds are offset along this direction and the web forms on the apron a continuous sheet whose lateral edges are defined by the folds.
  • the start of the nip is defined in the mobile position by an input carriage which moves back and forth intended to make the speed of admission of the web into the spreader and the speed of unwinding of the web compatible. by the exit carriage despite the back and forth movements of the latter.
  • the veil which is of fragile constitution is disturbed neither by piling, nor by stretching, nor by friction.
  • the comings and goings of the input carriage is compensated by the opposite comings and goings of the output carriage and vice versa thanks to an appropriate arrangement of the guide rollers (see for example FR - B - 2,553,102).
  • auxiliary carriages are provided which also move back and forth in translation to selectively lengthen or shorten the belts outside of the nip and thus compensate for variations in the length of the nip.
  • the present application relates more particularly to this second type of embodiment.
  • the driving of the main and auxiliary carriages is usually ensured by transmission members, such as toothed belts or chains, meshing on driving pinions whose rotation is controlled.
  • Each transmission member has one end fixed to a main carriage and its other end fixed to an auxiliary carriage, the movement of which must be synchronized with that of this main carriage to keep the length of the closed path followed by one of the belts constant.
  • the rotation of the pinion in a first direction pulls the main carriage in half of its back-and-forth movement, which would tend, all other things being equal, to increase the length of the corresponding closed path.
  • the belt following this closed path therefore undergoes a traction force, which is transmitted to the auxiliary carriage so as to control its translation necessary to keep the length of the closed path constant.
  • the rotation of the pinion in the second direction pulls the auxiliary carriage in the other direction, which applies a traction effect on the belt, this traction force being transmitted to the main carriage to make it describe the second half of its back and forth movement.
  • the drive mode described above is often preferred because it advantageously reduces the number of control members, a limited number of drive pinions being sufficient to control the translations of four carriages in each direction.
  • this embodiment has the disadvantage that the belts are constantly under tension because of the inertia of the carriages. As the carpets follow winding paths at relatively high speed, their repeated tensioning causes a certain wear which generally results in a cracked appearance of their surface, to the detriment of a regular and precise transport of the fibers constituting the veil.
  • the belts are therefore replaced periodically, which is expensive and immobilizes the machine for a long time.
  • the mats can be relatively thick, but they then move more difficult along their winding paths.
  • One of the aims of the present invention is to solve the above problems by proposing a new spreader-lapper in which the conveyor belts have increased durability and / or less thickness.
  • the invention thus proposes a spreader-lapper to transform by folding a veil into a tablecloth, comprising at least two belts each following a closed path and associated with rollers for their respective guidance and drive, the closed paths being external one to each other and adjacent to each other in a nip zone delimited by guide rollers carried by two main carriages movable in translation in a horizontal direction and perpendicular to the axes of the rollers, compensating means, comprising at least an auxiliary carriage movable in translation perpendicular to the axes of the rollers, in order to maintain substantially constant the length of each of the closed paths, each closed path having a 180 degree turn around at least one guide roller carried by an auxiliary carriage, means to bring the veil to the entrance of the nip, an apron movable in a direction parallel to the axes of the rollers and receiving the web at its exit from the nip, and drive means for applying back and forth translation movements to the main carriages and to the compensating means.
  • the spreader-lapper is characterized in that each main carriage is connected to an auxiliary carriage by coupling means which are less extensible than the belts, these coupling means being arranged to be tensioned under the action of the drive means.
  • the belts of the spreader-lapper according to the invention can advantageously be of lighter constitution without undergoing premature wear. They therefore more easily follow their respective winding paths to transport the veil smoothly, even at fairly high speeds.
  • the means for coupling an auxiliary carriage and a main carriage comprise at least one cable fixed at one end to the auxiliary carriage and at the other end to the main carriage, this cable being guided by pulleys between the auxiliary carriage and the main carriage.
  • This coupling mode has the advantage of a reduced bulk.
  • the spreader-lapper shown in perspective in FIG. 1 comprises a first mat 2, said front mat which collects the veil of fibers 4, for example from a card not shown, and transports it into the enclosure 1 where it is transformed by folding into a ply 6 transported by an apron 8 outside the enclosure 1.
  • the apron 8 transports the formed ply 6, for example to a needle not shown.
  • the directions of transport of the web 4 and of the web 6 are respectively indicated in FIG. 1 by the arrows F and K.
  • the interior of the spreader-lapper is shown schematically in the elevation views of FIGS. 2 to 4, taken along a plane Q perpendicular to the direction of transport of the ply 6 by the deck 8.
  • the spreader-lapper Associated with the front mat 2, the spreader-lapper comprises a second mat 5, called the rear mat.
  • the belts 2 and 5, shown in solid lines in FIGS. 2 to 4, have the same width and have their lateral edges in the same planes parallel to the plane of FIGS. 2 to 4.
  • the front carpet 2 follows a closed path consisting of sections 20 to 31 delimited by cylindrical guide rollers 32 to 43.
  • the rear belt 5 follows a closed path consisting of sections 50 to 59 delimited by cylindrical guide rollers 60 to 69.
  • the guide rollers 32 to 43, 60 to 69 are pivotally mounted around respective axes perpendicular to the plane of Figures 2 to 4, that is to say parallel to the direction of movement of the deck 8.

  • the axes of the rollers 34, 35 and 60, 61, 62, 63 are carried by a first movable main carriage 10, called the entry carriage.
  • the axes of the rollers 36, 37, 38 and 64 are carried by a second movable main carriage 14, called the exit carriage, and those of the rollers 41 and 67 are carried by auxiliary carriages 16, 18.
  • a movable auxiliary carriage 16, 18 For each closed path 20 to 31, 50 to 59 of the belts, a movable auxiliary carriage 16, 18 carries a guide roller 41, 67 around which this closed path makes a 180 degree turn.
  • the two auxiliary carriages 16, 18 have movements which compensate for those of the main carriages 10, 14 in order to keep the length of each of the closed paths 20 to 31, 50 to 59 substantially constant.
  • At least one of the rollers with fixed axis (for example the rollers numbered respectively 39 and 65) is rotated by known means not shown so as to circulate the belts 2, 5 along of their respective closed paths 20 to 31, 50 to 59 according to predetermined kinematic laws.

Upstream of the carriage input 10, the front belt 2 carrying the veil 4 follows the substantially horizontal section 21 coming from the front side 7. When arriving on the input carriage 10, the front belt 2 describes a first turn around the following return roller 34 an angle A of between 0 and 90 degrees oriented downwards to form the inclined section 22, then a second turn around the roller 35 at an angle B between 90 and 180 degrees to form the horizontal section 23 of the nip, directed towards the front side 7 of the spreader-lapper.

  • Two cables 92 extend on either side of the rollers and belts between the input carriage 10 and its associated auxiliary carriage 16, passing on the front side 7 of the spreader-lapper. Between the carriages 10 and 16 to which they are fixed by their ends, the cables 92 each bypass two return pulleys 93, 94 pivoting respectively about a fixed axis parallel to the axes of the rollers 32 to 43, 60 to 69.
  • the pulleys 93, 94 are arranged so that the end sections cables 92 are parallel to the direction of translation of the carriages 10, 16 to which they are respectively fixed.

  • the traction forces mentioned, useful for synchronizing the movements of the associated carriages, are advantageously absorbed by the cables 92, 96 because they are less extensible than the belts 2, 5. This provides an important advantage compared to the spreader-lappers of the prior art, in which these tensile forces are mainly absorbed by the belts. As a result, carpets are less stressed and can be lighter in constitution while having improved durability.
  • the light construction of the belts is very advantageous because it reduces the inertia of the machine and facilitates movement in the curved regions of their closed paths, which improves the regularity of the transport of the web 4 in these regions.
  • the veil 4 from the card is placed on the inclined section 20 followed by the front belt 2 (see Figure 4). After deflection on the roller 33, it is transported horizontally on the section 21 to the input carriage 10. On this, the web 4 is first deflected by the roller 34 at the angle A between 0 and 90 degrees. The moderate value of the angle A prevents the veil from being disturbed when it is deflected by the roller 34. After having been transported on the inclined section 22 of the front belt 2, the veil 4 bypasses the pinch roller 35. The pinch line defined between the rollers 35, 61 prevents the web 4 from peeling off the front belt under the action of centrifugal force.
  • the roller 34 deflecting the veil 4 at the angle A before the nip is mounted on the input carriage 10. It will be understood that the roller 34 could have its axis fixed relative to the chassis 1 of the spreader-lapper. In this case, the angles A and B are variable, but the input carriage is lighter and the roller 34 contributes to supporting the belt 2 upstream of the input carriage.
  • the auxiliary carriages can be located in separate lower passages, it is advantageous, to reduce the space requirement, to provide a single lower passage 70 in which the two auxiliary carriages 16 move. , 18.
