Definitions

  • the invention relates to a method according to the preamble of claim 1 and to a device suitable for carrying out the method according to claim 3.
  • Scraper rollers serve for crease-free spreading, but also guide and wide section rollers when it comes to guiding the web in a certain direction when spreading or correcting its running direction.
  • the web of material spread out on the spreader roller retracts again in a narrower position if it is not picked up by a fixing roller after leaving the slat or spreader roller and stabilized in its width position.
  • the extent to which the material web contracts again or is even laterally overstretched depends, in particular in the case of very sensitive and wide-meshed goods, on the tensile force with which the material web is pulled over the spreader roller to the fixing roller for the passage.
  • the rotation of the guide and spreader roller is solely due to liability of the web running over it, which is more or less smoothed and corrected by the guide and spreader roll by lateral pivoting according to its wrinkled position and running direction. Different tensile forces constantly occur in the web, which lead to considerable tension in the fabric. The result is a completely warped fabric web and a corresponding web winding, which also has a very disadvantageous effect on the further processing of the web.
  • the invention has for its object to improve a method of the type mentioned in such a way that the spread and aligned goods without deformation and distortion and always with the same clamping force on the fixing roller to stabilize, and also to provide a device for it.
  • the fixing roller is formed by the storage in pressure cells to the measuring roller, because the web running and deflected over the fixing roller exerts the respective pressure there with which it is pulled through the device.
  • This pressure component is passed on from the pressure cell as a control value via an amplifier to a drive of the guide and spreader roller or segmented regulating roller.
  • This drive accelerates or decelerates the running on the spreader roller and thus offers a continuous web tension, whereby the spread is balanced even with very sensitive fabrics and without tension.
  • the web tensile forces also increase, which is ultimately compensated for by faster drive of the spreader roller.
  • Practice has shown that the web tension is even reduced when the web runs smoothly. Reduce the control signals from the load cell in the case, the drive of the spreader roll, so that this control gives a uniform web tensile force between the guide and spreader roll and the fixing roll and tension in the web is avoided.
  • a device as can be seen from claim 3 is suitable for carrying out the method.
  • the tensile forces with which the material web is pulled over the fixing roller can be measured by using pressure load cells in the mounting of the fixing roller.
  • the fixing roller is thus designed as a measuring roller. Both one and both axle bearings of the fixing roller can be provided with pressure transducers. This will depend on the measurement accuracy desired.
  • the values determined in the pressure load cells are passed via an amplifier to a drive for the guide and spreader roll, whereupon the guide and spreader roll is correspondingly accelerated, throttled or continuously held in its rotation.
  • the measured values taken from the fusing roller determine the speed of rotation of the guiding and spreader rolls and thereby equalize the web tension between the spreader roll and the fixing roll to a constant value. As soon as the web tensile force acts largely uniformly on the spread web, no tension occurs in the fabric, which is particularly advantageous for sensitive and thin or wide-meshed goods.
  • Figure 1 shows a schematic side view of the device.
  • the web 2 is removed, for example, from a container 1 and spread out in its web width via a stripping roller unit 3. From there, the web 2 is fed to a guide and spreader roller 4, which is also referred to as a segmented roller. On this spreader roller 4, the web 2 is spread out without creases and is additionally guided in the predetermined direction by pivoting the entire spreader roller 4 sideways. This lateral pivoting takes place by means of a servomotor 5, which senses the peripheral edge of the web 2 of its position from the guide and spreader roller 4 downstream sensors and acts on the servomotor 5 via a position transmitter 7.
  • a servomotor 5 which senses the peripheral edge of the web 2 of its position from the guide and spreader roller 4 downstream sensors and acts on the servomotor 5 via a position transmitter 7.
  • the guide and spreader roller 4 is immediately followed by a fixing roller 8.
  • This fixing roller 8 is mounted with its axes in pressure cells 9, which are preferably provided on both axis ends. Through these load cells 9, the fixing roller becomes a measuring roller with which the web tensile force is measured, with which the web 2 over the guide and Spreader roller 4 is pulled to the fixing roller 8. From the fixing roller 8, which is wrapped by the web 2 by at least 90 °, the web 2 leads to a downstream web pulling device 10.
  • a tachometer generator 11 is provided on the web tension device 10, with which the web speed can be measured.
  • the resulting tensile and compressive forces which occur on the fixing roller 8 and which are caused by the web 2 running around and under tension are taken as control values from the pressure load cells 9 and fed to an amplifier 12 which sends control signals via a line 13 to a drive 14 for the guide and spreader roller 4 passes on.
  • This drive 14 is an electric motor with a flanged gear 19, which is attached to the axis 15 of the guide and spreader roller 4 and acts directly on it.
  • the amplifier 12 is associated with a setpoint specification controller 16, via which a minimum tensile force can be entered in the web run.
  • the amplifier 12 is in electrical connection with the tachometer generator 11 via a line 17, so that the web running speed from the web tensioning device 10 is also taken into account in the control signals given by the amplifier 12 via line 13 to the drive or motor 14.
  • a control device 18 is connected to the position transmitter 7, with which the sensitivity of the sensor 6 for controlling the servomotor 5 can be set.
  • the guide and spreader roller 4 with the rotary drive 10 and the downstream fixing roller 8 as well as the amplifier 12 and the associated switching parts with their electrical conductive connections are a structural unit, which is documented in the drawing with the dashed line 20.
  • This assembly is held on a console, not shown, which is flanged to the overall device and can be inserted or removed in a simple manner in the processing line of the fabric web.
