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 a plurality of fiber webs, sheets or mats with fibers running essentially parallel to the large surfaces are stacked on top of one another and from this stack Slices consisting of individual strips perpendicular to the grain and cut so 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 method.
  • 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, whereby a new web with several strips lying next to one another fibers aligned essentially perpendicular to the large surfaces.
  • a horizontally oscillating knife can only cut one strip from the fiber web at a time.
  • the strips will be cut to different heights, resulting in an unevenly thick web, plate or mat-like mineral fiber body.
  • DDR-PS 93408 describes a process for the production of mineral wool lamellar mats and mineral wool lamellar webs, according to which mineral wool panels are assembled into packages and cut into mineral wool lamellar panels of any thickness and, if necessary, further processed into mineral wool lamellar webs. 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, and neither does the US Pat. No. 3,230,995 and US Pat. No. 3,345,241, which are also to be considered in the prior art.
  • a method and an apparatus for producing a non-woven fiber web are already known, wherein a strand consisting of longitudinally oriented fibers is brought into a sheath and the tubular sheath filled with the fibers is cut at one end by a cutting device is, the cut fiber strand pieces in guides through a conveyor belt and transferred to guides from which they are fed to a cutting device. Before cutting, the end face of the respective fiber strand piece is held in place by a vacuum zone until it is placed on a further horizontal conveyor belt at the moment in which the vacuum is released.
  • the method described in this literature reference relates to a completely different genre and can therefore give no suggestion for the method according to the invention.
  • 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 the drive of the conveyor belt covering the pivotable suction device is controlled via, depending on the pivoting movement of the suction device, actuated, possibly even contactless limit switches.
  • the pivoting suction device can be actuated hydraulically and pneumatically by a piston, but also mechanically, e.g. can be controlled by a camshaft, a spindle or the like. After the fiber strips have been sucked onto the conveyor belt with the aid of the suction device, the pivoting process takes place, only then is the conveyor belt started up, with which the individual strips are passed on to the downstream conveyor device.
  • Non-contact limit switches are the photocells known per se, but also magnetic switches, the impulse of which is given by metattapes attached to the conveyor belt.
  • FIG. 1 shows in FIG. 1 a device for producing web-like, plate-like or mat-like fiber shaped bodies 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 embodiment shown, so that the stack of fiber mats or sheets 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 adjustment device.
  • a hydraulic or pneumatic cylinder 7 is provided which, via control elements, pivots the suction device 3 and the conveyor belt 5.
  • 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.
