Definitions

  • the invention relates to a fabric laying machine according to the preamble of claim 1.
  • the invention has for its object to simplify a fabric laying machine of the type specified.
  • the air flow is advantageous to dimension the air flow only so strongly that the web end section is not fluttered up, but is only slightly raised, so that the friction between the web section and the table surface is reduced and the web section can be easily advanced.
  • the end of the web reaches the front end of the take-off table, it is automatically deflected downward around the front end due to the force of gravity, the end of the web coming down between a preselecting roller and a deflecting roller rocker which is open at this time, if such a pre-setting device is present.
  • the flow rate of the air stream is preferably somewhat greater than that of the fabric.
  • the configuration according to the invention is characterized by simplicity, functional reliability and, in particular, low structural and functional expenditure. It can be manufactured easily and inexpensively and contributes to a substantial reduction in costs for the fabric laying machine.
  • the main parts of the fabric laying machine 1 are a horizontal laying surface 2, a laying carriage 4 which can be moved back and forth in the longitudinal direction (double arrow 3) by a drive (not shown), the top side a horizontal extraction table 5 and above, preferably in the longitudinal center, a carrying device 6 for one Fabric supply 7, here a roll of fabric, which also has on its front 8 a fabric specification device 9 and below it a fabric cutting device 11, and to which a compressed air supply device 12 is assigned.

  • the guide plate 47 serves to deflect the free end of the web down into the distance a between the specification roller 38 and the deflection roller 44.
  • the take-off table 5 only has to extend to the rear so far that the web end section 19 lowered from the stock of material 7 reaches the table surface 18, the air nozzle or air nozzles 23 being arranged in the rear end region of the take-off table 5 or on the back of the web end section 19.
  • the air nozzles 23 and 23a are formed by a bore 28a, which increases slightly with the angle W and emerges from the table surface 18 outlet or nozzle opening 32a lying in the table surface 18 is elongated due to the oblique course in the longitudinal direction of the laying carriage 4.
  • the bores 28a can originate from a common transverse channel or here a transverse groove 27b, which can be covered, or a tube, here a square tube, can be firmly inserted in the groove 27d which is open at the top and the front side wall of which penetrates the associated bore 28a.
  • the top of the tube 27c closes with the table surface 18 flush.

  • the vertical width of the nozzle slot or the nozzle opening 32b is only a few tenths of a millimeter, preferably approximately 0.2 to 0.4 mm.
  • Such an embodiment can be formed in a simple and advantageous manner by a thin cover plate 14c, which covers the opening 28c of the associated compressed air supply channel 28 or the groove in the flow direction, for example by the amount, in the table surface 18 of the associated compressed air supply channel 28 or groove c from about 1 to 5 mm.
  • the cover plate 14c can extend on the rear side so far that it covers the transverse groove 27b.

  • the upper edge of the transverse edge 14d is preferably rounded.
  • the slot portion 32c (Fig. 8) present in the face region is suitably, e.g. by gluing, closed, since a lateral air outlet is not necessary and can be avoided.
  • the cover plate 14c can overlap the front side wall of the transverse groove 27b by a few millimeters. If this overlap is larger, in order to avoid flow losses, it is advantageous to provide the preferably inclined recess 28 in the overlap area between table surface 18 and cover plate 14, which runs out a few millimeters in front of nozzle opening 32b in table surface 18.

  • the feed line section 26 penetrates the feed line sections 26a, 26b in a sealed manner through the dividing surface or joint 48a between the rotatable fume cupboard 5 and it load-bearing part of the laying carriage 4.
  • the dividing joint is directed horizontally and is formed by a flat lower surface of the rotatable extraction table 5 and a flat surface of the cross slide 37.
  • the air nozzles 23 and 23a are preferably switched on and off as a function of the opening or pivoting position of the rocker 42.
  • a switch 55 can be provided which the rocker 42 actuates and which generates a control signal which is used to switch on the associated air nozzles is used.

  • the air nozzles 23 and 23a blow the web end section 19 in the associated direction of movement, thereby moving it forward and at the same time creating an air cushion between it and the table surface 18 on which it slides slightly forward.
  • the guide plate 47 or deflection plate prevents the end of the fabric web from being driven too far during rapid threading.
  • the end of the fabric section then passes through the sensor 56, whereby the lateral position of the fabric is monitored and the existing centering device — if necessary — centers the fabric by deliberately moving the cross slide 7.
  • the roll of fabric is further lowered by the distance a between the input roller 38 and the deflection roller 44, for example up to the vicinity of the cutting device 46.
  • the rocker 42 is pivoted in. This can be done manually or by means of a sensor, not shown, which monitors the end edge of the fabric end section and generates a corresponding control signal.
  • the switch 55 is actuated and the air nozzles 23 are switched off.
  • the preset roller 38 is driven by switch actuation or uncoupled from its drive so that it can be easily rotated, for example by hand, and rotated until the front edge of the fabric web reaches its correct position on the front edge of the laying shovel 57 of the cutting device 46.
  • the empty run in the right end position and then the fabric laying while driving in the left end position can be done in the usual way according to the so-called one-way process.
