Definitions

  • the present invention relates to a method for manufacturing flags or similar products constituted of a rod-shaped body and a sheet mounted thereon.
  • the method according to the invention is characterized by the features stated in the characterizing part of claim 1.
  • the paper sheet after the following folding round the rod-shaped body, is firmly attached to the rod-shaped body only using heat and pressure.
  • the method is suitable for mechanical manufactur ⁇ ing of flags.
  • the flags may especially advantageously be manufac ⁇ tured in a continuous process wherein the rod-shaped body is supplied in the form of a substantially endless wire.
  • the flags manufactured in this method are especially suitable for food products, either as cake flags or advertising flags in connection with displays of foodstuffs, as the flags may be manu ⁇ factured under very hygienic conditions without being touched by hu- mans and furthermore, bacteria will have very poor grow conditions because of the plastic used.
  • the method is not only suitable for manufacturing of flags, but it may also be used in the manufacturing of flag festoons using a suit- able rod-shaped body, e.g. plastic-coated wire or plastics wire may be used onto which the flags are welded.
  • a suit- able rod-shaped body e.g. plastic-coated wire or plastics wire may be used onto which the flags are welded.
  • Fig. 1 shows a principle sketch of an apparatus for use in a method according to the invention
  • Fig. 2 a principle sketch for illustration of an apparatus for use in a further embodiment of the method according to the in ⁇ vention
  • Fig. 3 a partial view for illustration of a detail of the manufac ⁇ turing.
  • FIG. 1 illustrates schematically a method for continuous manufacturing of flags 1.
  • a spool 2 contains a substantially endless supply of wire 3 of a thermoplastic plastic.
  • a storage container 4 contains a supply of separate sheets 5 of flag paper.
  • the sheets 5 are taken out in a manner known per se and are conveyed continuously and parallell with the wire 3 by means of a conveyor belt 6 provided with carriers 7 which ensures a correct mutual positioning of the sheets 5.
  • the wire 3 and the sheets 5 are inserted between two conveyor belts 8 and 9 which secure their mutual position.
  • the wire 3 and the sheets 5 are conveyed through a folding device 10 whereby the sheets 5 are folded round the wire. Then the wire 3 around which the sheet 5 is folded is inserted between two heated nip rolls 11,12.
  • the plastic By the passage between the nip rolls 11,12 the plastic is heated to a sufficiently high temperature and for a sufficient period of time to ensure that the welding is achieved. After the passage through the nip rolls 11,12, the wire and the sheets 3,5 are still secured between the conveyor belts 8,9 in order to ensure their mutual fixing until the materials are cooled off sufficiently.
  • a cutting mechanism 13 which may optionally be activated is positioned after the nip rolls 11,12. When the cutting mechanism 13 is activated it operates synchronously with the forward conveying of the wire 3 so that separate flags 1 are formed where the sheets 5 are at the one end of each attached wire. It is noted that operation of the cutting mech- anism 13 may be discontinued thus permitting manufacture of flag fes ⁇ toons.
  • the wire is selected according to the desired object to be made. Thus a more stiff wire is selected when flags are made and a more pli ⁇ able wire, optionally a plastics-coated wire of cotton or the like is selected when flag festoons are made.

  • the edge portion of the sheet 5 which is preferably provided without the use of dye are folded approx- imately round the entire circumference of the wire 3.
  • the nip rolls 11,12 are shown with a nip profile 13 adapted to the diameter of the wire 3.
  • it also will be possible to treat the edge portions of the sheet 5 to improve the welding. It may for instance be possible to apply a coating of plastic on this edge portion.
  • the nip rolls 11,12 are provided with suitable milled grooves (not illustrated) in order to ensure that the pressure is exerted only when a flag is passing between the rolls.
  • the rotation of the nip rolls 11,12 is adapted to the conveying of the wire/flags.

  • the edge portions 16 of the sheet 15 which are intended for engagement with the rod 14 are free of dye.
  • the rods 14 are contained in a supply 17 from where they are conveyed au ⁇ tomatically along a path 18 to a position in between two heated sub ⁇ stantially rectilinear nip jaws 19,20.
  • the edge portion 16 of the sheet 15 is folded round the rod 14 as explained above whereafter the two jaws provided with profiled grooves (not shown) corresponding to the grooves 13 nip round the flag and sheet assembly for a sufficiently long period and at a sufficiently high pressure for obtaining a weld ing.
  • the jaws 19,20 are withdrawn whereupon the finished flag 1' is displaced away from the jaws by means of the succeeding rod 14 which is carried forwards and is positioned between the jaws 19,20.
  • the sheets 15 are fixed firstly in relation to the rod 14 of the onset of the nipping of the jaws. How ⁇ ever, it will also be possible with this method to use two conveyor belts corresponding to the belts 8 and 9 in Fig. 1 nipping round the rods 14 and the sheets 15 and fixing the latter in relation to each other.
  • the method illustrated in Fig. 2 is more suitable for larger flags, e.g. with a rod length ranging up to 0,5 metre while the method illu ⁇ strated in Fig. 1 is suitable for smaller flags, so-called cake flags with a flag pin length of approximately 50 to 100 mm.
  • larger flags are manufactured it is of particular importance that the jaws 19,20 are heated to a sufficiently high temperature to establish a welding only in mutually separated areas as crumpling of the paper or optional ⁇ ly release of the sheet 15 from the rod 14 due to the expansion and the contraction of the rod during the heating and the succeding cooling is hereby omitted.
  • the plastic should be heated as little as possible in order to avoid the problems of crumpling or optional release of the sheet from the rod.

Abstract

Selon un procédé de fabrication de drapeaux (1), il est possible d'éliminer l'emploi de colle, le processus d'assemblage étant adapté pour une automatisation, étant donné que ledit drapeau est constitué d'un fil (3) de thermoplastique, et que le papier du drapeau est constitué d'une feuille (5), laquelle est pliée autour dudit fil (3) au moyen d'un dispositif de pliage (10). Le pliage (10) a lieu simultanément avec le transport en continu dudit fil (3) et desdites feuilles (5), au moyen de bandes de manutention (6, 8, 9) assurant en même temps un positionnement mutuel correct. Ledit fil (3) et lesdites feuilles (5) sont soudées au moyen de rouleaux à contact linéaire (11, 12), utilisant de la chaleur et de la pression. On procède à un découpage à l'aide d'un dispositif coupant (13), lequel est synchronisé avec le transport dudit fil (3) et desdites feuilles (5), afin de former des drapeaux séparés (1). Ce procédé est particulièrement adapté à la fabrication de petits drapeaux, par exemple des drapeaux à gateaux ou des drapeaux de décoration.
