Definitions

  • ABSTRACT A cross-lapping device for cross-lapping pile or laying web to form fleece, according to which one or two rotatable blade wheels in addition to the cross-lapping means, preferablytogether therewith, are reciprocable in such a way that an air current is generated which is directed toward the lateral rim portions of the fleece to be cross-lapped.
  • the present invention relates to a cross-lapping device for cross-lapping pile or laying web to form fleece.
  • All heretofore known cross-lapping devices regardless of their construction, have the drawback that the guidance of the air during the back and forth movement of the cross-lapping carriage takes place in an uncontrolled manner. This results in an air suction which in particular with a laying web of low specific weight causes a disadvantageous turning over at the lateral margins or rims of the fleece to be cross-lapping.
  • FIG. 1 diagrammatically illustrates a side view of a cross'lapping device according to the invention with blade wheels or drums and adjustable guide hoods therefor.
  • FIG. 2 shows in a more detailed manner and by way of an isometric view the arrangement of FIG. 1.
  • FIG. 3 diagrammatically illustrates a speed variable drive for the blades of the blade wheels or drums.
  • FIG. 4 shows a device for adjusting the position of the blades of the blade wheels or drums.
  • the present invention is characterized primarily in that adjacent the leasing devices there are provided one or more drivable blade wheels or drums, which are preferably movable back and forth together with the leasing devices, in such a way that an air flow is generated which is directed at the lateral margins of the fleece to be leased.
  • the speed and/or the position of the blades of the blade wheels can be varied.
  • the blade wheels have associated therewith adjustable guiding blades by means of which the air flow can be guided in a desired direction.
  • the pile or laying web 1 is crosslapped between so-called mangle or calender rollers 2 and 3 to form a fleece 4 which is withdrawn on a transversely moving surface in the direction of the arrow (FIG. 2).
  • the pile l is passed over a feeding table 5.
  • this feeding table 5 and the mangle or calender rollers 2 and 3 are arranged on the cross-lapping carriage 10 which by means of the rollers 11 ismovable back and forth on a frame 12 in the direction of thedouble arrow 13a to form folds in thefleece on the moving receiving surface.
  • a suction effect occurs in the direction of movement, especially at the reversing points of theback and forth movement.
  • This suction effect is to be equalized or compensated for in conformity with the principle of the present invention. According to the invention, this is brought about by generating a directed air flow which counteracts the suction effect.
  • two blade wheels or drums 6 and 7 which are rotatable and adapted to generate an air flow directed toward the lateral rim areas 4a of the fleece 4 and prevent the pile or laying web from being turned over.
  • the two blade rollers or drums 6 and 7 are preferably likewise arranged on the crosslapping carriage l0 and thus are adapted to be moved back and forth together with the feeding table 5 and the calender rollers 2 and 3.
  • the blade drums 6 and 7 rotate in opposite direction with regard to each other as indicated by the arrows I3 and 14.
  • Each of said blade rollers or blade drums 6 and 7 has a protective hood 8 associated therewith.
  • a protective hood 8 associated therewith.
  • the static pressure generated by the rotating blade drums 6 and 7 is preferably selected so as to be greater than or equal to the underpressure generated by the movement of the crosslapping carriage 10.
  • FIG. 3 diagrammatically illustrates a drive for blade drums with variable speed of rotation thereof.
  • the drawing illustrates by way of example a drive for the blade drum 6 arranged on the outside of calender roller 3.
  • the drive is derived from the driven calender roller 3 by means of the driving belt 16.
  • a change in the speed of the blade drum 6 is possible by the stepped pulleys l7 and 18 on calender rollers 2 and 3 respectively.
  • FIG. 4 diagrammatically illustrates a device for adjusting the position of the blades 6a and 7a of blade drums 6 and 7 respectively.
  • the blades are slidably arranged in slots 19 and by means of the device of FIG. 4 can be more or less moved out of or into the respective slots 19.
  • the blades 6a are equipped with adjusting pins 20 which axially project beyond the periphery of the roller body 6. These pins 20 are respectively acted upon from drum shaft 21 by pressure springs 22 in outward direction against the inner mantle of an adjusting funnel 23 while the pressure springs and said adjusting funnel rotate with the blade drum 6 and shaft 21 thereof.
  • Shaft 21 is supported in bearing support 25 by means of the bearing 24.
  • a cross-lapping device for cross-lapping a web onto a receiving surface to form folds in said fleece, which includes a reciprocable carriage having a feeding table and calendar rollers between which the web is fed and is crosslapped, whereby said web is folded at each end of movement of said reciprocating carriage to form folded edges, blade wheel means at opposite ends of said carriage between said calendar rollers and the end of said carriage to direct a current of air onto the folded edge at each end of the travel of said carriage, and drive means to drive said blade wheel means.
  • control means associated with said blade wheel means for variation of the speed of rotation of said blade wheel means.
