Definitions

  • the present invention relates to a machine for covering carding sails, which comprises a plurality of continuous bands associated with a plurality of carriages movable in reciprocating reciprocating movements, the movement of the movable carriage located in the lower part determining the positioning. card web on the conveyor.
  • Layer machines are known which comprise several continuous strips associated with several trolleys which can be moved in reciprocating back and forth movements.
  • the card web which will form the ply is placed on the strip located in the upper part of the machine, the movement of the carriage associated with this strip being that which will cause the other strips to move successively. It is the carriage located in the lower part of the machine which determines the positioning of the card web on a conveyor which is under the band located in the lower part.
  • the reciprocating back and forth movement and the advancement of the conveyor means that the entire conveyor is covered by the card web, forming the sheet.
  • this type of lapping machine has the disadvantage that the card veil is uncovered in certain parts of the machine, where the air can lift it because the card veil is very light.
  • the card veil is lifted in some parts, when placed on the conveyor, it may be improperly positioned and the web may be irregular.
  • the speed of the movable carriages and of the conveyor must be very low.
  • the machine object of the invention succeeded in solving the drawbacks mentioned, and has other advantages which will be described.
  • the machine object of the invention is characterized in that it comprises first and second continuous bands located substantially symmetrical with respect to the vertical longitudinal plane of symmetry of the machine, the first and second bands being associated with a first and a second movable trolleys, the movement of the first trolley or lower trolley determining the positioning of the card web on the conveyor, the second trolley moving due to the tension of the first and second belts when the first trolley moves and in the opposite direction to it last, also comprising a third continuous strip associated with a third carriage located between the first and second carriages, this third carriage moving in the same direction as the first carriage, said bands being located very close together to drive the card web the upper groove defined between the first and second strips at the ra lower edge which crosses the first carriage, also defined by the first and second bands.
  • the coating machine object of the invention comprises means for synchronizing the movement of the first and third carriages.
  • the means for synchronizing the movement of the first and third carriages are two belts, each of which is connected to a side of the machine and to the first carriage, and which mesh with a third wheel secured to the third carriage, so that the movement of the first carriage involves movement of the third carriage in the same direction.
  • the movement of the first carriage is actuated by a motor.
  • the first and second strips pass around a roller, these two rollers being integral with the third carriage, one of these rollers being connected to the third carriage by a transmission which rotates the third strip.
  • the motor which actuates the first carriage which also moves the second and the third carriage.
  • the second carriage is moved by the action of the tension of the first and second bands
  • the third carriage is moved by the action of the synchronization means mentioned.
  • the lapping machine of the invention comprises means for adjusting the tension of the first and second strips.
  • the means for adjusting the tension of the first and second strips comprise, for each of them, a first plate secured to the frame of the machine and a second plate secured to the movable support on which the lateral rollers through which the strip passes are mounted, and a screw and nut mechanism arranged between these plates.
  • the coating machine of the invention comprises three continuous strips 1, 2, 3, which are symmetrical with respect to the axis 4 when they are in the middle position.
  • the first 1 and second 2 bands are associated with a first carriage 5 in its lower part and with a second carriage 6 in its upper part, while the third band 3 is associated with a third carriage 7.
  • the first 1 and second 2 bands pass around a plurality of rollers 8, 9, 10.
  • Two of these rollers 8, those which are located in the central and upper part of the machine, are those which actuate the movement of the bands first 1 and second 2 on the rollers 8, 9, 10 mentioned.
  • Two other rollers 10, located in the upper part of the machine but at a level below the actuator rollers 8, are associated with the second carriage 6.
  • the first 1 and second 2 bands also pass around a roller 11, these rollers 11 being integral with the third carriage 7.
  • the third band 3 also passes around a pair of rollers 12, the pivoting of these rollers 12 being actuated through one of the rollers 11 by a transmission belt 13.
  • the carriages 5, 6, 7 can be moved in reciprocating back-and-forth movements, the movement of the first carriage 5 determining the positioning of the card web on a conveyor 14.
  • Figure 1 an end position of the rollers 9, 10, 11, 12 in a continuous line, and in a broken line is shown the other end position.
  • the first carriage 5 is actuated by a motor (not shown).
  • the movement of the first carriage 5 causes the second carriage 6 to also be displaced by the tension of the first 1 and second 2 bands.
  • the movement of the third carriage 7 is also produced by the movement of the first carriage 5, as described below.
  • the belt 15 passes around a wheel 16 secured to the first carriage 5 and around a roller 18. At the same time, the wheel 16 is also secured to the third carriage 7, which means that when the first carriage 5 moves , the third carriage 7 also moves in the same direction in a synchronized manner.
  • FIG 3 is shown the coating machine object of the invention, which comprises on its two sides means 18 used to adjust the tension of the first 1 and second 2 bands. These are the means 18 shown in the figure which regulate the tension of the first band 1, while on the opposite side of the machine are the means 18 which regulate the tension of the second band 2.
  • the means 18 serving to adjust the tension of the first 1 and second 2 bands comprise for each of them a first plate 20 secured to the frame of the machine and a second plate 21 secured to a support movable on which are mounted the side rollers 9 through which the strip passes, and a screw mechanism 19 and nut arranged between these plates 20, 21.
