Definitions

  • the invention relates to a method for producing web, plate or mat-like mineral fiber bodies with fibers oriented at least approximately perpendicular to the large surfaces, in which several fiber webs, plates or mats with fibers running essentially parallel to the large surfaces are stacked on top of one another and from This stack of disks consisting of individual strips is cut off perpendicular to the grain of the fiber and folded over in such a way that their cut surfaces become the large surfaces of the mineral fiber body.
  • These products are also known as lamellar mats.
  • Such a method is of particular interest because web, plate or mat-like mineral fiber bodies with fibers oriented at least approximately perpendicular to the large surfaces have a very high compressive strength and tear resistance.
  • the invention further relates to a device for performing this Procedure.
  • a fibrous web is fed perpendicular to a horizontally running conveyor belt and strips are cut from this fibrous web with the aid of a horizontally oscillating knife, which fall onto the horizontally running conveyor belt, with a new web having several adjacent strips fibers aligned essentially perpendicular to the large surfaces.
  • a horizontally oscillating knife which fall onto the horizontally running conveyor belt, with a new web having several adjacent strips fibers aligned essentially perpendicular to the large surfaces.
  • DDR-PS 93408 describes a process for the production of mineral wool lamellar mats and mineral wool lamellar sheets, according to which mineral wool sheets are assembled into packages and cut into mineral wool lamellar sheets of any thickness and, if necessary, further processed into mineral wool lamellar sheets. This publication says nothing about how the further processing into the mineral wool lamellar webs takes place, in particular how the individual strips are rotated, just as little as the US Pat. Nos. 3,230,995 and US Pat 3,345,241.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of creating a method and a device which is particularly expedient for carrying it out, with the aid of which the production of such web-like, plate-like or mat-like shaped fiber bodies by means of very simple process steps or by means of a device can be easily accomplished even by inexperienced forces.
  • the advantage that can be achieved by the invention is, in particular, that the desired fiber moldings with fibers oriented at least approximately perpendicular to the large surfaces are obtained in one operation as a whole in an orientation that enables immediate further processing. Furthermore, the method according to the invention can be fully mechanized if the development of the device according to the invention is controlled by the drive of the conveyor belt covering the swiveling suction device via, depending on the swiveling movement of the suction device, actuated, possibly even contactless E h d switch.
  • the actuation of the swiveling suction device can be hydraulic and pneumatically by a piston, but also mechanically, e.g. B. can be controlled by a camshaft, a spindle or the like.
  • Non-contact limit switches are known photocells, but also magnetic switches, the impulse of which is given by metal plates attached to the conveyor belt.
  • the drawing shows in FIG. 1 a device for producing web-like, plate-like or mat-like fiber moldings with fibers oriented at least approximately perpendicular to the large surfaces.
  • FIG. 2 A modified embodiment of such a device is shown in FIG. 2 using essentially the same reference numerals.
  • a cutting device 2 At the front end of a support table 1 in the direction of transport there is a cutting device 2, furthermore a suction device 3, which can be pivoted about the axis 4 and is covered by an at least partially air-permeable conveyor belt 5. Fiber mats or plates 6 are stacked on the support table 1 up to the desired height.
  • the support table 1 can be moved back and forth in the illustrated embodiment, so that the stack of the fiber mats or panels 6 can be passed under the cutting device 2 step by step.
  • the cutting device 2 can be arranged to be movable and the table immovable, in particular when the cut is made through the cutting device 2 from top to bottom.
  • the suction device 3 By means of the suction device 3, the strip disc 6a consisting of the cut fiber strips is sucked onto the conveyor belt 5 and then an interval between the fiber plates 6 and the disc 6a is generated from the fiber strips by tilting the suction device 3 about the axis 4.
  • the tilting or swiveling movement can be carried out by any known adjusting device.
  • a hydraulic or pneumatic cylinder 7 is provided, which carries out the pivoting of the suction device 3 and the conveyor belt 5 via control elements.
  • the pivot axis 4 must be set so far lower from the base of the lowermost fiberboard by the distance a that the pivoting movement also attracts the lowermost fiber strip of the disc 6a from the stack of fibrous mats or panels.
  • the pivoting movement is then continued into the position shown in dashed lines, so that in this end position a perfect transfer of the slice of fiber strips from the conveyor belt 5 to the subsequent conveyor device, which in the embodiment according to FIG. 1, a further conveyor belt 8 and in the embodiment according to FIG 2 is a slide 8a.
  • the mats or plates consisting of the fiber strips can then be laminated on one or both sides and, if necessary, separated into two mats or plates of the same or different thickness by a longitudinal cut perpendicular to the fibers.
