Definitions

  • the invention relates to a method for the continuous production of an expanded metal-like, flat strip according to the preamble of claim 1 and to a device for carrying out this method according to the preamble of claim 2.
  • the object of the invention is to provide a method and a device for carrying it out, with which an expanded metal-like, flat strip can be produced in an extremely simple and continuous manner from an endless metal strip with the features of the preamble of claim 1.
  • This object is achieved according to the inventive method in that the metal strip is continuously detected in the region of the side edges of feed means and in that traction means are provided which continuously subject the central region of the metal strip to a tensile force in the longitudinal direction of the strip during the feed movement.
  • the device proposed for performing the method is characterized in that two pairs of outer rollers are used as the feed means and as a traction means an inner roller pair lying between the outer roller pairs is provided, each roller pair forming a gap in which the metal strip lies frictionally, that the peripheral speed of the inner roller pair is greater than that of the outer roller pairs and that the lower roller of the inner roller pair is opposite the assigned upper roller in the feed direction of the metal strip is offset.
  • a device of the type in question is already known from DE-PS 30 48 712, in which the cross-slotted metal strip runs between two rotating stretching rollers, each of which is provided with two circumferential beads opposite a longitudinal strip of the metal strip or a smooth outer surface.
  • the longitudinal strips between the circumferential beads and the lateral surface are stretched, so that the transverse slots of the metal strip widen to form transverse openings.
  • the expansion is achieved by rolling reducing the strip thickness by means of the stretching rollers acting on the strip edge, which is to be avoided in the proposal described here.
  • the upper rollers of the outer roller pair are non-rotatably and the upper roller of the inner roller pair are freely rotatable on a drive shaft, the associated lower rollers of the outer roller pair being freely rotatable and the lower roller of the pair of inner rollers is firmly connected to a drive shaft.
  • FIG. 1 shows a partial top view of the metal strip, which is the starting product of the expanded metal-like, flat structure 2 according to FIG. 2. This structure 2 is produced using the method or device according to the invention.
  • incisions 1a and 1b are provided which are perpendicular to the two side edges of the metal strip 1 and which are spaced apart and parallel to one another and are center-oriented.
  • the incisions 1a are opposite to the incisions 1b.
  • a side edge-oriented incision 1c is provided in the central region of the metal strip 1, which is parallel to the incisions 1a, 1b oriented towards the center of the strip.
  • the metal strip 1 is continuously detected in the region of the side edges of feed means, traction means being provided which continuously subject the central region of the metal strip 1 to a tensile force during the feed movement.
  • traction means being provided which continuously subject the central region of the metal strip 1 to a tensile force during the feed movement.
  • the expanded metal-like, flat strip shown in FIG. 2 of the drawing is formed, in which triangular recesses are formed in the central region and gusset-shaped recesses in the region of the two side edges.
  • Two pairs of outer rollers 3, 4 and 5, 6 serve as feed means, while an inner roller pair 7, 8 lying in between is provided as the traction means, the peripheral speed of the inner roller pair 7, 8 being greater than that of the two outer roller pairs 3, 4 and 5, 6 .
  • Each pair of rollers has an upper roller 3, 5, 7 and lower roller 4, 6, 8 forming a gap, in which gap the endless metal strip 1 lies frictionally.
  • the lower roller 8 of the pair of inner rollers 7, 8 is offset in relation to the assigned upper roller 7 in the feed direction of the metal strip 1 by the amount a, where a corresponds approximately to the distance of the cuts center-oriented from the side edge-oriented cuts.
  • the diameter of the top rollers 3, 5, 7 is the same size; the diameter of the lower rollers 4, 6, 8 is also the same size.
  • the diameter of the lower rollers 4, 6, 8 relates to the diameter of the upper rollers 3, 5, 7 as the length of the stretched metal strip 2 to the length of the undrawn metal strip 1 the peripheral speed of the outer roller pairs 3, 4 and 5, 6 to that of the inner roller pairs 7, 8 as the quotient of the length of the unstretched metal strip 1 and the length of the stretched metal strip 2.
  • the operation of the device for carrying out the method according to the invention is as follows:
  • the metal strip 1 shown in Figure 1 is inserted into the gap between the rollers 3, 7, 5 and 4, 8, 6. Since the top rollers 3, 5 are driven and the bottom rollers 4, 6 act as counter pressure rollers, the metal strip 1 moves continuously in FIG. 3 perpendicular to the plane of the drawing.
  • the outer roller pairs 3, 4 and 5, 6 serve as feed means. Due to the staggered lower roller 8 and the upper roller 7 acting as a counter-pressure roller, a tensile force is continuously exerted on its central region during the advancing movement of the metal strip 1, which ensures that the metal strip 1 shown in FIG. 1 is pulled apart in the manner of an accordion, so that a Expanded metal-like, flat structure is created.
