Definitions

  • the invention relates to a device for introducing a relatively loose pile brought up from a brim or the like via a conveyor belt or the like into a downstream roller system, in particular a calender, while reducing the pile height before entering the roller system.
  • the invention has for its object to provide a device of the type mentioned, by means of which the working speed can be increased significantly by improving the introduction of the pile into the roller system and drastically reducing the tendency to build-up due to air turbulence.
  • this object is achieved in a device of the type mentioned at the outset by a roller system Upstream pile guide device for compacting the pile by pressing it against the conveyor belt.
  • the floral device has at least one pile roller rotating in the same direction as the conveyor belt.
  • the surface of the pile guide roller (s) is smooth.
  • the surface of the pile guide roller (s) is profiled.
  • the invention also provides that the pile guide roller (s) is or are designed as a perforated roller.
  • a further embodiment of the invention proposes that the pile guide device has at least one printing table or the like moving in the same direction as the conveyor belt in the direction of the roller system.
  • the printing table has an air-permeable peripheral screen cloth or the like.
  • the screen cloth is designed with a profile.
  • the invention also provides that the screen cloth is provided with perforations.
  • the invention optionally further proposes that the pile guide roller (s) or the printing table (s) separately is or are driven.
  • a further development of the invention optionally provides that the pile guide roller (s) or the printing table (s) is or are designed to move.
  • a further embodiment of the invention is characterized in that the pile guide device has at least one pile or tinsel sheet or the like pressing against the conveyor belt.
  • the tinsel is profiled.
  • the tinsel is perforated.
  • the invention also provides for the tinsel to have a smooth surface.
  • a further development of the invention is optionally also characterized in that the distance between the pile guide device and the conveyor belt is adjustable.
  • the pile guide Due to the pile guide provided according to the invention, by means of which the pile is largely freed from the scent that is brought in before it enters the calender roll system without the application of noticeable compressive forces by pre-compression by pressing on the conveyor belt, the pile can be introduced into the calender even at high levels Working speeds due to the compression of disturbances occurring on air turbulence etc., such as otherwise they occur, particularly in the case of strongly compressed floras, to keep them free, which means that the working speeds are no more than 60 m / min compared to the previously customary values. up to over 100 m / min. let increase. Defects and quality losses, such as have previously been observed when there is a tensioning delay between the conveyor belt and the calender, do not occur.
  • the pile guide device be it a pile guide roller or a printing table
  • the pile guide roller optionally also being a pin roller
  • a number of pile guide rollers and / or printing tables and / or tinsel plates connected in series can be provided between the card and the calender in order to achieve the desired pre-compression of the pile in stages.
  • Fig. 1 is upper half of a conventional conveyor belt 10, a pile table or the like, by means of which a relatively looser pile 12 is fed from a brim or the like, not shown in the drawing, to the left of the conveyor belt 10 or the like, to a downstream roller system, consisting of two calender rollers 14, 16, one perforated Florleitwalze 18 arranged - whose distance is adjustable relative to the conveyor belt 10 and by means of which in the manner shown in the drawing, the approaching from the brim, still relatively loose pile 12 is compressed so much that when the pile compressed in this way enters of the calender roll system 14, 16 no more air jam occurs, which could lead to puffing up of the pile and thus to a hindrance when the working speed is increased.
  • the pile guide device has a print table 20, here provided with a separate drive, instead of the pile guide rolls 18 provided in FIG. 1, the peripheral screen cloth 22 of which is provided with perforations in order in this way to remove the from the Ease pile of air pushed out.
  • the pile guide provided according to the invention has a tinsel plate 24, which hangs down from a correspondingly mounted support bar 26 onto the pile 12 . 2, can be adjusted relative to the conveyor belt 10 in order to vary the passage bar between the conveyor belt and the pile guiding device, so that different degrees of compaction of the pile 12 can be achieved, whereby it should be pointed out that by means of the pile guiding device provided according to the invention, a pre-connection of the bottom and top pile is also achieved can be.
