Definitions

  • Asslgnee' Screemex Helens comprises the steps of positioning an expansible or ex- England tensible bag or bags within the interior of said cylinder [22] Fil d; 11 4 and filling said bag or bags under pressure so as to form a substantially rigid body or bodies which bear [2H Appl' 441,440 firmly against the wall of the printing cylinder, or a part or parts thereof, to reinforce it against inward [30] Foreign Application priority Data crushing or collapse.
  • Screen printing cylinders are used extensively in the colour printing of textile fabrics, carpets, wallpapers and the like. Having regard to the amount of work and skill and consequential cost involved in the making of screen printing cylinders, it is most important that they should be well protected against damage during transit from, for example, the place of manufacture to the place where they are to be used.
  • a method of packaging a screen printing cylinder which includes the steps of positioning an expansible or extensible bag within the interior of the screen printing cylinder and filling said bag under pressure so that it will form a substantially rigid body which bears firmly against the wall of the printing cylinder or a part or parts thereof, to reinforce it against inward crushing or collapse.
  • the bag preferably is filled under pressure with a suitable material in particulate, granular or like form.
  • a suitable material which has been found very suitable for the purpose of the invention, consists of beads of an expanded polymeric material e.g. polystyrene.
  • the beads are relatively small e.g. have a diameter of the order of one-sixteenth inch to one-eighth inch.
  • the wall of the bag is perforated, preferably with a multiplicity of very small perforations, so as to allow air to escape where the bag is being filled under pressure with the beads of polystyrene or other material.
  • the ends of the bags are caused to project beyond the ends of the assembly of printing cylinders so as to prevent damage to the cylinders should the package be dropped on end.
  • the present invention also provides a transit package containing at least one screen printing cylinder having within it at least one bag ,which has been filled under pressure so as to form a rigid body which reinforces the screen printing cylinder internally against inward crushing or collapse.
  • the bag is filled with small beads of expanded polystyrene.
  • FIG. 1 is a perspective view of a transit package for a plurality of screen printing cylinders enclosed in a packing case, shown in broken lines,
  • FIG. 2 is a longitudinal sectional view of the package shown in FIG. 1, and
  • FIG. 3 is a cross-section, on the line llllll of FIG. 2.
  • the reference numeral 10 indicates an assembly of several screen printing cylinders which have been temporarily deformed or given a kidney-like cross-section, as shown, so that they can be inserted one within the other for transit even although they are normally of the same diameter.
  • the assembly of cylinders is slid into an elongated packing case 11 of, for example, cardboard orsome other material, the outermost cylinder being a snug fit in the packing case.
  • a suitably shaped elongated block 12 of polymeric material such as expanded polystyrene is inserted, as a snug sliding fit, centrally into the assembly of cylinders so as to extend for the whole length thereof.
  • Further polystyrene or other packing may be provided between the assembly of cylinders and the interior surfaces of the packing case as may be required to hold the assembly firmly in the packing case.
  • Two identical elongated tubular bags 13 of POLY- THENE are then inserted, in a flat condition and in side-by-side relationship, through the assembly of cylinders and so that the ends 13a of the bags extend well beyond both ends of the assembly of cylinders.
  • the ends of the bags at one end of the assembly of cylinders are then sealed by means of clips or ties 14.
  • the other ends of the bags are similarly sealed but only after the nozzles, of a pressurized air filling apparatus for the bags, have been inserted thereinto.
  • the said filling apparatus is then operated so that the bags are charged under pressure with a mass of small beads of polystyrene.
  • the bags 13 have previously been perforated with a multiplicity of very minute perforations so as to allow the air to escape whilst leaving the polystyrene beads within the bags.
  • the extended ends 13a of the bags 13 are then sealed, by a heat sealing process. as indicated at 15, and tucked into the ends of the cardboard packing case.
  • the packing case is then closed completely and securely by means of cardboard end pieces 16.
  • the screen printing cylinders Before being inserted into the packing case the screen printing cylinders may be enclosed exteriorly in a double walled sock or wrapping, the spaces between 3 the walls, of said sock or wrapping, being subsequently charged under pressure with polystyrene beads so as to fill any cavities between the cylinders and the interior surfaces of the packing case.
  • the screen printing cylinders are firmly encompassed externally and tightly packed internally with the polystyrene beads and a very robust package is the result.
  • a transit package having packed within it at least one screen printing cylinder reinforced internally by two expansible bags, filled with material in particulate form, in spaced parallel relationship and a reinforcing block located between the expansible bags so as to occupy any space therebetween when the latter are filled, forming a substantially rigid body which bears firmly against the wall of the cylinder or against a part of the screen printing cylinder to reinforce it against inward crushing and collapse.
  • said at least one screen printing cylinder is the inner cylinder of an assembly of such cylinders packed one within another, the outer cylinder of the assembly being deformed temporarily to a flattened oval shape and the inner ones to a shape of kidney-like cross-section.
  • a method in accordance with claim 2, wherein the material in particulate form comprises beads of an expanded polymeric material.
  • expansible bags are made of a flexible plastics material and are perforated with a multiplicity of small perforations.
  • expansible bags when positioned in the cylinder are in the form of elongated open-ended tubes, one end being sealed before filling the bags under pressure the other end being sealed after filling the bags under pressure.
