Definitions

  • the invention relates to a method and a device for inserting a tubular web with the formation of Z-folds in a circular fabric hose during weaving and laying flat in a circular weaving machine.
  • a folding device which places the flat-lying tubular web in Z-folds at certain intervals.
  • the Z-folds are enclosed and fixed between the mutually facing strands of a double belt conveyor, which extends into the area of the pair of rollers laying flat and pulling off the round fabric hose, so that the Z-folds are fixed between the converging walls of the round fabric hose after leaving the double belt conveyor.
  • the object of the invention is therefore to propose a method and a device which allow the outer fabric tube to be lined with a film tube with annular Z-folds which follow one another at intervals.
  • this object is achieved in a method of the type mentioned at the outset in that the tube web squeezed between the pairs of flat-lay and feed roller is inflated into a bladder and the bladder is supported in an annular manner on and at a distance from the weaving ring in such a way that it is between the annular supports bulges, and that the annular bulge formed by the bulge, with its edge remote from the weaving ring, is inserted into the weaving ring with the formation of an annular circumferential Z-fold.
  • a device for carrying out the method according to the invention is characterized in that above the weaving ring a pair of preferred rollers feeding the tubular web and between this and the weaving ring a cylindrical ring enclosing the inflated tubular web and concentric to the weaving ring, the outside diameter of which is smaller than the inside diameter of the weaving ring, are arranged, and that the ring is provided with drive and guide devices which move it in the axial direction between a position above the weaving ring and a position retracted into the weaving ring.
  • the tubular web can be laid in Z-folds at a distance from the length of hose piece to be separated later from the round fabric hose for sack production, the tubular web possibly being attached to the round fabric hose above the Z-folds by adhesive applications.
  • the cylindrical ring is inserted into the weaving ring when the tube bladder is stretched by pivoting the flaps in such a way that it forms an annular bead between the ring and the weaving ring.
  • the tubular web adheres to the weaving ring in such a way that the bead is drawn in through the cylindrical ring which dips into the weaving ring, forming Z folds, and is then peeled off from the inner wall of the weaving ring until the Z folds of the desired length are formed.
  • the tube sheet is provided with adhesive through the gaps in the ring, which are pressed against the inner wall of the circular fabric tube due to the overpressure of the air in the tube bladder.
  • the tube bladder is then put into its slack state, so that the ring can be moved out of the weaving ring without pulling out the Z-fold formed again.
  • the adhesive nozzles are expediently arranged on the carrier of the cylindrical ring and can also be moved in the longitudinal direction of the slots.
  • a folding cylinder 6 is arranged above the weaving ring 1 and consists of a ring bracket 7 and a cylinder 8 attached to it made of relatively thin material.
  • This cylinder 8 has four incisions 9. Its outer diameter is smaller than the inner diameter of the weaving ring 1, so that the cylinder 8 can be immersed more or less deeply in the weaving ring 1 by lowering the entire folding cylinder 6.
  • an inlet ring 10 is firmly connected to the latter, which ring consists of a plurality of one Axis of teflon rolls lined up.
  • this inlet ring 10 two plates 11 and 12 are pivoted toward and away from one another, between which the tubular film 14 transported by the preferred rollers 13 runs.
  • 9 adhesive application nozzles 16 are provided in the area of the incisions, which can be moved up and down together with the folding cylinder and can also be moved relative to the folding cylinder.
  • the tubular film 14 is inflated into a bubble between the preferred rollers 13 and the pair of draw rollers 5 with only slight pressure by injection with a needle or the like. While the circular tube 4 is now being woven, the tubular film 14 is simultaneously drawn in as an inner tube. The preferred rollers 13 and the pair of rollers 5 are driven at the same peripheral speed. If the swivel plates 11 and 12 are now moved towards each other, the hose bladder is compressed at this point. The displaced air causes the film 14 to press outwards between the folding cylinder 6 and the weaving ring 1 and form a bead 15. Depending on the width of the incisions 9, the film 14 can also be pressed out here. If the bead 15 is formed, the folding cylinder moves downwards at a higher speed than the take-off speed determined by take-off rollers 5 and dips into the weaving ring 1 until a Z-fold 17 of the desired depth has formed.
  • the preferred rollers 13 are driven at an increased speed which is adapted to the speed of the folding cylinder 6.
  • both the lowering speed of the folding cylinder 6 and the speed of the preferred rollers 13 are adapted to the speed of the pair of rollers 5, which is always driven at a constant peripheral speed.
  • adhesive emerges from the nozzles 16, which are connected to the ring console 7, for example, via hydraulic piston-cylinder units (not shown). By acting on these piston-cylinder units, the nozzles 16 are moved upwards, that is to say in the direction of the console 7, as a result of which four adhesive strips are applied to the tubular film 14 evenly distributed over the circumference.
  • Sacks are then formed from the round fabric web with the inner tube inserted, for example 50 kg sacks, in which the inner sack is connected to the outer sack by four adhesive strips in the area of the upper opening edge, so that the inner sack opens when it is opened for filling is brought up in any case.
  • the Z-fold inserted immediately below the adhesive strips is gradually pulled open by the inflowing material, so that the inner sack can lie on the outer sack without tension and thus has no supporting function.

1. Procédé pour insérer un film tubulaire avec formation de soufflets en forme de Z dans un tissu tissé de manière circulaire au fur et à mesure que celui-ci est tissé et aplati dans un métier à tisser circulaire, caractérisé par le fait que le film tubulaire est écrasé entre des paires de rouleaux aplatisseurs et les rouleaux d'alimentation et est gonflé pour former un film tubulaire gonflé qui est appuyé dans des zones annulaires par l'anneau de tissage et à distance de celui-ci, de manière que le film tubulaire gonflé se renfle entre les appuis annulaires et que le bourrelet annulaire formé par le renflement est poussé dans l'anneau de tissage à l'extrémité distale du bourrelet par rapport à l'anneau de tissage, formant ainsi un soufflet annulaire en forme de Z.
