ABSTRACT:
The present invention relates to a method of manufacturing a knitted article.
The invention relates more particularly but not exclusively to manufacturing a beret.
BACKGROUND OF THE INVENTION
A beret or an analogous article is knitted in conventional manned/by means of a knitting machine having two rectilinear or flat needle beds, a front bed and a back bed, at least one of the beds being capable of being racked, each of the beds also being provided with needles enabling stitches to be transferred from one bed to the other.
It is known to knit in successive rows of stitches on both beds until there remain thereon only two edges to be assembled together, and then to unite the edges after the article has been transported to a linking machine.
Proposals are made in French patent application FR-A-2 409 337 and in European patent application EP-A-0 063 518 to eliminate the use of a linking machine and of the associated labor by transferring each of the stitches constituting one of the edges from one of the beds to the other and then uniting the stitches by sewing using a special sewing device, but that has the drawback of complicating manufacture of the knitting machine.
OBJECTS AND SUMMARY OF THE INVENTION
The present invention seeks to facilitate the manufacture of a beret or the like.
The invention achieves this by means of a novel manufacturing method, of the type in which the article is knitted by means of a knitting machine having two rectilinear beds, comprising a front bed and a back bed, at least one of the beds being capable of being racked, each of said beds also being fitted with needles enabling stitches to be transferred from one bed to the other, the article being knitted until there remain on the beds only two edges that are to be assembled together, wherein said edges are assembled together by knitting a chain-stitch seam that is turned towards the inside of the article.
In a preferred implementation of the invention, the seam is knitted while racking only the back bed, only the front bed, or both the front and bed beds simultaneously until there remain only a few occupied needles on the beds, in such a manner that if the progress of the knitting of the seam is observed when all of the needles in the two beds are exactly in register, each stitch that has just been knitted on one of the beds is to be found, after being transferred to the other bed, offset by two needles in the seam knitting direction, the stitches being knitted alternately on one bed and then on the other.
In a particular implementation of the method of the invention, the seam is knitted by means of an assembly technique comprising the following steps, the two beds initially being in a position where they are offset by two needles.
Preferably, a knitting machine is used having knocking-over bits with incorporated springs.
Also preferably, the article is knitted in successive sectors of stitch height that is generally increasing from the center of the article towards its periphery.
The invention also provides a knitted article, in particular a beret, closed on itself by means of a chain-stitch seam that is directed towards the inside.
By means of the invention, the article can be knitted entirely on the knitting machine without any need to transfer the piece of knitting to a linking machine or to add a special sewing device to the knitting machine.
This provides a saving of labor and makes it possible to use a conventional knitting machine without any need to modify it by adding a sewing device.
