Definitions

  • the present invention relates to the field of the machines for knit wear, and more precisely relates to a method for production of collars having portions with double yarn colour on a flat bed knitting machine with two carriages.
  • Two carriages move on a guide parallel to the needle beds, or needle beds, and make two identical articles, with single or multiple system, i.e. carrying one or several yarn guides at a time.
  • Machines of this type can also be used in the production of collars, which are rectangular shaped knitted articles, in single colour or with many colours.
  • collars with many coloured bands a frequent case is that of two coloured bands knitted at alternate ranks, in order to provide fancy patterns or inscriptions.
  • the collar can have also one or several bands with single colour and one or several bands with two colours.
  • the pattern with two colours either can be obtained with the needles moving independently from one another, in jacquard machines, or consists in a not complex interlock with two colours, or pique, or a different pattern, for example formed by small squares. In both cases, the carriage must work every rank of stitches with a different yarn guide.
  • a starting or final step is provided with linked carriages and double system with yarns of two different colours.
  • a flat bed knitting machine with at least two carriages and single system that move along needle beds, comprising:
  • the means for adjusting the distance may comprise a device chosen among:
  • a knitted article for example a collar, has a band of stitches with double colour 2, for example comprising a fancy pattern, an inscription, etc., obtained alternating ranks of stitches knitted with a first colour yarn and ranks of stitches with a second yarn, with either the technique having independent needles (Jacquard) or with the technique having needles not independent.
  • double colour 2 for example comprising a fancy pattern, an inscription, etc.
  • the collar 1 has furthermore two portions 3 and 4 knitted with a same yarn of a single colour.
  • a flat bed knitting machine 10 is capable of knitting two collars 1a and 1b using two carriages 11a and 11b moving on double needle bed 12 dragged integral to each other by a belt 13, shown only diagrammatically.
  • yarn guides 14 slidable on rails 15, yarn stretchers 16 mounted on a frame 17, and yarn feeding spools 18 mounted on a support 19.
  • the machine of figure 2 can operate as shown in figures 3A, 3B, 3C, and outlined in table 2, for reducing the inefficiencies when knitting the portions with double colour.
  • carriages 11a and 11b are arranged distanced for knitting separately the single colour portions 3a, 3b, with single system like in a known tandem machine.
  • the strokes of carriages 11a and 11b are set according to the size of the collars and are given by the alternate movement of belt 13.
  • the end of the strokes can be seen by the extreme position of carriages 11a and 11b shown respectively with a continuous line and with a dotted line.
  • carriages 11a and 11b are linked quickly and automatically so that the first carriage 11a knits a rank of stitches with a yarn guide 14 of a first colour and carriage 11b knits a rank of stitches with a yarn guide 14 of a second colour.
  • Carriages 11a and 11b when coupled have a stroke about double with respect to the case of figure 3A, as shown by the extreme positions of carriages 11a and 11b indicated respectively with a continuous line and with a dotted line.
  • carriages 11a and 11b are separated again, quickly and automatically, for knitting portions 4a and 4b with single colour, as shown in figure 3C.
  • carriages 11a and 11b can be arranged in different alternative ways, four of which are outlined in figures 4A-4D.
  • FIG. 4B A way alternative to that of figure 4A is shown in figure 4B, wherein carriages 11a and 11b are connected to each other by means of a piston cylinder 21, or other known linear actuator.
  • a quick release clamp is not necessary, since carriage 11a can be also supported by belt 13 but sliding on it, or supported by carriage 11b by means of cylinder piston 21, or by a support not shown.
  • a further embodiment provides two parallel belts 13a and 13b, shown in the top plan view of figure 4C.
  • One of the belts, 13a is driven directly by a motor 22, used normally for moving the carriages.
  • Belt 13b instead, is brought into movement by a clutch 23, which can be released for approaching/distancing the carriages from each other in the steps as above described.
  • belt 13 is toothed and a motor 24, for example a step motor, brakes carriage 11a and drives the relative movement with respect to carriage 11b for approaching/distancing it at the dead centre position.
  • a motor 24 for example a step motor
