Definitions

  • the invention relates to a rotary screen printing machine, comprising at least one cylindrical stencil and a counterpressure roller interacting therewith, and also a printing belt made of a reinforced elastic material, to be attached temporarily to material to be printed.
  • the pattern to be printed is applied to a seamless cylindrical screen (the stencil) and the printing paste is applied from the inside by means of a squeegee through the screen openings to the material to be printed, for example textiles.
  • a squeegee through the screen openings to the material to be printed, for example textiles.
  • a pattern is separated into colour components.
  • a stencil is needed for each colour here.
  • the material to be printed is guided between the various stencils and the counterpressure rollers interacting therewith. It is pointed out that the various stencils are also known as printing positions.
  • the material to be printed is attached to the printing belt prior to printing, generally using an adhesive, which adhesive must have such properties that, while the two layers do not slip relative to each other during the printing, the printed material can still be separated easily from the printing belt after printing.
  • An important quality parameter for a good printed result is the fact of whether the different colours of a pattern fit well together, in other words match properly. This matching is determined by coordinating the individual printing positions (therefore the various stencils) and the position accuracy of the material for printing with these positions. The accuracy of the different patterns on the material to be printed can be seen immediately and is easily fixed.
  • the printing belt is subjected to various, changing forces in the rotary screen printing machine, such as the drive, process forces (i.e. the printing itself), the washing device (for removal of the adhesive layer used), the adhesive device for applying an adhesive layer for attaching the material for printing to the printing belt, and the belt drive.
  • Each of these forces causes a local or general stretching of the printing belt, which reduces the position accuracy of the material to be printed.
  • the temperature also has its effect, due to the fact that it can result in a length variation.
  • printing belts made of a reinforced rubber-like material are used in order to deal with the position inaccuracy. More particularly, these printing belts are made of a cotton or polyester fabric which is embedded in a nitrile butadiene rubber or urethane rubber. Such rubbers are found to have good adhesive and washing properties, which makes them excellent for use in at least the surface layer of a printing belt.
  • the invention is therefore characterised in that the material of the printing belt possesses high rigidity.
  • the rigidity of the belt is understood to signify the resistance to stretching in the lengthwise direction which is measured as the relative length change of the belt expressed in a percentage at an applied force of 1 N per mm belt width.
  • the printing belt preferably has a rigidity which is such that the stretch is less than 0.05%, more particularly less than 0.01%, at an applied force of 1 N per mm belt width.
  • the printing belt according to the invention preferably also has a rigidity leading to a stretch of less than 0.005% at an applied force of 1 N per mm belt width.
  • printing belts for use in rotary screen printing machines are of the endless type, and are a width of up to about 3.20 m and a length of 12 to 40 m.
  • a printing belt formed from a synthetic rubber reinforced with synthetic polymer fibres, in particular nitrile butadiene or polyurethane rubber reinforced with aramide fibres, while this printing belt, of course, meets the requirement that the stretch should be less than 0.05%, preferably less than 0.01%, at an applied force of 1 N per mm belt width.
  • the invention also relates to the use of a printing belt with high rigidity, suitable for use in a rotary screen printing machine.
  • the material of the printing belt preferably has a rigidity leading to a stretch of less than 0.05%, in particular less than 0.01%, expediently less than 0.005%, at an applied force of 1 N per mm belt width.
  • the invention also relates to a method for printing material, in particular textiles, using a rotary screen printing machine, in which the material to be printed is temporarily attached to a printing belt, which is characterised in that a printing belt of high rigidity is used.
  • the printing belt to be used in the method according to the invention in particular has a rigidity which leads to a stretch of less than 0.05%, preferably less than 0.01%, at an applied force of 1 N per mm belt width, and is preferably made of nitrile butadiene or polyurethane rubber reinforced with synthetic fibres, in particular with aramide fibres.
  • Fig. 1 shows the principle of rotary screen printing.
  • the pattern to be printed is applied to a stencil, such as cylinder 1, and paste (p) is pressed by means of squeegee element 7 from the inside out through the stencil 1 onto the fabric (or material to be printed) 8, forming a printed fabric 9.
  • paste (p) is pressed by means of squeegee element 7 from the inside out through the stencil 1 onto the fabric (or material to be printed) 8, forming a printed fabric 9. Since the fabric itself is not rigid enough to pass through the process with a good result, this material is temporarily attached to a printing belt 10, usually by means of an adhesive layer, which can be washed off when the printing process has been completed.
  • Roller 1a is a counterpressure roller which interacts with stencil 1.
  • Fig. 2 shows schematically a textile printing machine with 4 printing positions in the form of 4 stencils 1, 2, 3 and 4 with counterpressure rollers 1a, 2a, 3a and 4a respectively.
  • the printing belt 10 is of the endless type, and this belt is guided along the printing positions by means of the reversing rollers 5 and 6.
  • a printing belt of high rigidity preferably a rigidity leading to a stretch of less than 0.01% at an applied force of 1 N per mm belt width.
  • This belt is expediently formed by a woven fabric of aramide fibres to be embedded in nitrile butadiene or in polyurethane. These polymers have good adhesive and washing properties, which is necessary for temporarily attaching the material to be printed to the printing belt.
  • the invention is not limited to these materials, but other materials can also be used, provided that they meet the specifications set above.
  • the belt On account of its use in a rotary screen printing machine, the belt must be made endless; for this the person skilled in the art has various techniques at his disposal, which will not be discussed any further here. The choice of a specific technique will, however, depend partly on the type of woven fabric.
