Definitions

  • the applicator may be a botttomless container, the lower edges of which are formed by flexible lips of rubbet or similar material and thus act as squeegees in that on each stroke the trailing rubber strip forces the colouring matter before it over the stencil and through the openings in it. No great difficulty arises so long as the colouring matter is a fairly viscous paste.
  • pile fabrics and particularly pile carpets are to be printed, I have found it necessary to use a free-flowing liquid as the colouring matter, in a bottomless container, to apply suction to the underside of the stencil and to maintain substantially constant the pressure difference set up across the stencil and fabric by the head of the liquid and the suction, all as described in our US. Patent 3,129,- 442.
  • means are provided for applying suction along and outside each squeegee to draw away colouring liquid leaking under it.
  • suction is advantageous in that colouring liquid that has leaked beneath the edges of the squeegees is removed by the suction.
  • FIGURE 1 is a diagrammatic elevation of the first apparatus
  • FIGURE 2 is a diagram of an applicator above a stencil
  • FIGURE 3 is a diagrammatic vertical section through the applicator
  • FIGURE 4 is a longitudinal vertical section through part of a modified applicator.
  • FIGURES 5 and 6 are cross-sections in the lines VV and VIVI respectively in FIGURE 4.
  • FIGURE 1 shows part of a machine for printing carpets, comprising a main frame 1 that includes a support 2 over which the carpet is moved in step-by-step fashion during printing in a series of printing stations.
  • a stencil 3 At each printing station there is a stencil 3 and a colour applicator 4.
  • the stencil 3, as shown in FIGURE 2 is formed by a central screen 50 which has imperforate ends 51 lying within a frame 52, and in operation the applicator 4 comes to rest at the end of each stroke on one of the imperforate ends 51 and on the next stroke reciprocates across the stencil as shown by arrows A and comes to rest on the other imperforate end.
  • the stencil and applicator At the end of each stroke the stencil and applicator are lifted as a whole to allow the carpet to move.
  • the applicator shown in FIGURE 3 has a central pressure chamber 5 for colouring liquid lying within a suction chamber 6 both chambers being mounted on a block 8.
  • the block 8 carries two rubber members 9 of inverted U-shape which extend over the whole length of the applicator, that is to say over the whole width of the machine.
  • the inner walls 10 of these members 9 constitutes squeegees lying on each side of a space 11 to which passages 12 in the base of the chamber 5 and the block 8 lead.
  • Passages 13 are formed through the members 9 and the block 8 to put the suction chamber in communication with. the spaces within the members 9.
  • the applicator is closed at the top except for openings to which pipes 14 and 15 are connected.
  • the pipes 14 branch from a pipe 16 which is connected to the pressure side of a pump 17 by which colouring matter is drawn from a container 18 and supplied to the central chamber 5 through tubes 7 which extend upwards through the top of the suction chamber 6.
  • the pipes 15 branch from a suction pipe 19 which is connected to a suction pump 20, the pressure side of which delivers to the container 18.
  • both the pumps 17 and 20 runs continuously so that colouring liquid is supplied to the central chamber 5 and suction is applied through the suction chamber 6 to the interiors of the members 9.
  • colouring matter that leaks beneath the squeegee 10 and builds up in the spaces between the members 9 to the level of the bottom of the passage 13 is drawn away and returned to the container 18.
  • the outer walls of the members 9 ' act as outer squeegees, and in effect bound chambers outside the squeegees constituted by the squeegees 10, the suction being applied to these chambers.
  • the applicator shown in FIGURE 3 may be used with advantage whenever positive pressure on the liquid is desirable.
  • a pattern to be printed on a carpet often is formed by relatively large areas of different colours, for example of seven different colours, and fine lines of another colour.
  • the printing may be effected in two stages with the use of an applicator as shown in FIGURES 4 to 6 and with the application of suction to the underside of the carpet.
  • the applicator of FIGS. 46 is a box-like structure having end walls 21 and side walls 22.
  • An assembly 23 extends from one end wall to the other within the side walls and is composed of a top header section 24, a middle chamber section 25 and a bottom printing section 26.
  • the top header section 24 is bounded at the underside by a horizontal partition 27 and is divided longitudinally by vertical partitions 47 into alternating suction and supply pipes 30 and 31 are connected. There 'are three suction chambers 28 and two pressure chambers 29. Below the partition 27 the middle section 25 is divided by vertical partitions 48 into a further pressure chamber 54 and two lateral suction chambers 32 and 33.
  • Passages 34 are made through the partition 27 to put both the pressure chambers 29 in communication with the chamber 54, and passages 49 are made in the same partition to put all the suction chambers .28 in communication with both the suction chambers 32 and 33.
  • a nozzle 35 lies beneath the bottom of the chamber 54 and receives colouring liquid from this chamber through opening 36. This nozzle 35 lies in a space 37 between two longitudinal members 38, on the undersides of which there are doublelipped squeegees 39.
  • the assembly 23 is spaced away from the long side walls 22 to form chambers 41 and 42 which communicate with the atmosphere through passages 43.
  • Squeegees 44 are clamped to the side walls 22 by plates 50 and form the lower boundaries of the chambers 41 and 42, which communicate with the chambers 32 and 33 through passages 45.
  • the squeegees 44 are suitably shaped by bevelling the lips to ensure the best possible contact with the stencil at the end of each stroke, and while the stencil is lifted.
  • the suction is applied to the chambers 41 and 42, which are bounded by squeegees but which are also open to atmosphere, with the result that colouring liquid can build up in them to the level of the bottoms of the passages 43 when printing is not taking place.
  • Trunnions 46 are provided on the end walls for engagement by lifting mechanism not shown.
  • suction is applied to the underside of the perforated support 2 through a suction box 53, the top of which is formed by the support 2, as shown in FIG- URE 1.
  • This suction is continuously applied throughout the whole of each printing stroke, but is destroyed and replaced by positive pressure at the end of each stroke to enable the carpet or other fabric easily to be moved through one step to bring a fresh length into each printing station.
  • printing by an applicator as shown in FIG- URES 46 may be carried out without the use of suction under the fabric.
  • printing is effected by the colouring liquid in the outer chambers 41 and 42 under gravity alone, and continued by the liquid in the centre space 37 under pressure.
  • the invention enables uniform printing to be effected, without the use of timing devices for cutting off the supply of colouring liquid.
  • a stencil-printing machine for pile fabric comprising a stencil having imperforate ends and a central perforated part, a support for the fabric passing beneath said stencil, and applicator means mounted for reciprocating movement over said stencil and having a bottom opening extending over the entire length of said applicator means for the supply of free-flowing coloring liquid under pressure to said stencil, a pair of inner squeegees secured to said applicators means on opposite sides of said opening and adapted to bear on said stencil, a pair of outer Squeegees secured to said applicator means and spaced from said inner squeegees on opposite sides thereof to define bounding chambers extending over the entire length of said applicator means outside said inner Squeegees, and means for applying suction to said chambers to draw away coloring liquid leaking under said inner squeegees into said chambers.
  • said applicator means further comprises a central pressure chamber flanked by two suction chambers and flexible means connected to the tops of said chambers for supplying liquid to the pressure chambers and suction to the suction chambers.
  • a stencil-printing machine according to claim 1 wherein said applicator means further comprises a central pressure chamber lying within a suction chamber and flexible means connected to the tops of said chambers for supporting liquid to the pressure chamber and suction to the suction chambers.
  • each outer bounding chamber is open to atmosphere to allow colouring liquid to build up in it when printing is not taking place.
