Definitions

  • the invention relates to a device for producing blown films of a thermoplastic material.
  • the operating principle is based on extruding the melt produced by at least one extruder of thermoplastic material from an annular outlet opening of a tool and inflate to a hose which is subsequently folded by a so-called flattening device, passed between take-off rolls and subsequently fed to a take-up.
  • the invention proposes to arrange between the flattening elements and preferably extending to the take-off rolls guide vanes on both sides of the film tube, which embrace during the flattening of the film tube forming edge fold of the film tube and defined in the gap between the Feed the extraction rollers.
  • the vane may be made of suitable plastics or e.g. be made of aluminum, if it is in contact with the film tube or even with the film tube facing porous, preferably microporous surface for the outlet of a supplied air flow and for generating an air cushion for the purpose of contactless guidance of the film tube to be equipped.
  • a microporous surface is understood to mean a mean pore size of between 5 and 100 ⁇ m.
  • the distance of the guide vanes according to the invention to subsequent take-off rolls should be selected to be low and is preferably adjustable so that preferably a defined guidance of the edge fold of the film tube into the nip of the take-off rolls can be effected. If possible, a guidance of the edge rebate takes place until close to or immediately before the take-off rolls, ie with the smallest possible distance to the squeeze rolls.
  • the guide vanes proposed according to the invention preferably form the upper end of side guide elements of a side guide device, which are arranged between the flattening elements of the flattening device and effect a guide of those peripheral regions of the film tube which are not currently loaded by the flattening elements, ie, the gradually forming edge fold and the adjacent areas of the film tube.
  • the side guide elements may be formed from a support structure with adjusting means and support arms fastened to the support structure, which for their part carry, for example, guide means for the film tube fastened to holding forks.
  • guide means are pivotally mounted on the support arms about a pivot axis extending in the exit direction of the film tube.
  • the adjustment of the articulated interconnected and segment-like continuous support leg can be made variable not only in terms of the angle enclosed between adjacent support legs angle, but also with respect to the horizontal distance to each opposite side guide element to make an adjustment to the diameter of the film tube.
  • the individual support legs are e.g. with a suitable telescoping also longitudinally adjustable design, which offers additional degrees of freedom to adapt to the desired contour of the flat film tube to be laid.
  • the guide means are preferably arranged in the region of the lateral guidance elements provided according to the invention in such a way that they support the film tube in the largest possible peripheral areas and support it in a three-dimensional manner together with the flattening elements.
  • the adjustment of the individual support legs can be accomplished for example via spindle drives or other suitable drives with high positioning accuracy, more preferably each support leg has its own adjustment.
  • the adjusting drives in turn can also be connected to one another centrally.
  • Fig. 1 is a schematic side view of an inventively designed device
  • FIG 3 shows the plan view of a part of a side guide element designed according to the invention.
  • FIG. 1 shows, in a roughly schematic representation, a film tube 1 produced from an extrusion device in a known manner and vertically upwards in an exit direction A, which is gradually folded into a flat film tube by means of flat-laying elements of a flattening device which are not shown in more detail Gap between parallel take-off rollers 5 is pulled through. Furthermore, a side guide element 2 belonging to the flattening device can be seen, which, of course, is arranged in mirror image to the central longitudinal axis of the film tube 1 also on the opposite side.
  • the side guide members 2 continuously guide the film tube 1 in the region 400 of larger diameter during this plane from the cross section Q1 to the cross section Q4, i. between the flattening elements according to reference numeral 300.
  • Each side guide element 2 consists according to Figure 1 of a support structure with three reference numerals 20, 21, 22 supporting legs, which are connected to each other via joints 23, 24, i. are concatenated.
  • guide means 27 may be provided in pairs at the free end of each support arm 25, which are pivotally mounted as needed via a pivot axis S extending in the direction of advance of the film tube 1 in order to optimally adapt to the circumference of the film tube 1.
  • a guide shell 27a is provided instead of guide means in the form of rollers, which overlaps the forming edge fold 10 of the flattened film tube 1 on the outside and for an exact guidance thereof to the take-off rollers 5 provides.
  • the guide shell 27a is adjustable relative to its distance from the take-off rolls 5 and their angular orientation to the support leg 20 and performs the edge fold 10 of the film tube exactly in the gap between the drawing rollers congruent in the drawing arranged fifth Due to the articulated connection of the individual support legs 20, 21, 22 with each other, they are mutually adjustable relative to each other in terms of the included angle in adaptation to the desired contour of the film tube.
  • a separate drive 28 may be provided for each support leg 20, 21, 22 without connecting these drives with each other.
  • the support legs 20, 21, 22 are independently adjustable in the direction of the diameter D of the film tube and can also be telescoped in the direction of arrow T, i. be formed variable in length.
  • each support leg at least one support arm 25 for a guide means having.

Abstract

La présente invention concerne un dispositif de réalisation de films de soufflage comprenant un dispositif d'extrusion produisant un film tubulaire, et un dispositif d'application à plat associé au film tubulaire et comprenant deux éléments d'application à plat disposés dans des zones diamétralement opposées du film tubulaire, qui peuvent être réglés pour former un angle aigu l'un par rapport à l'autre et qui servent à faire passer la section tout d'abord circulaire du film tubulaire à des sections ovales pour finalement former un film plan double, et une paire de cylindres d'étirage en aval du dispositif d'application à plat, servant à étirer le film plan, des ailettes directrices se trouvant entre les éléments d'application à plat, lesdites ailettes enveloppant le bord replié du film tubulaire qui se forme lors de l'application à plat de celui-ci.
