ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a method of connecting two knitted parts on a flat knitting machine.
During the manufacture of knitted articles which are assembled of several individual knitted parts, it is necessary as a rule to provide tooth-working steps which generally are not automated and therefore are cost intensive. For a rationale manufacture of knitted articles, it is therefore necessary to develop a method of machine connection of knitted parts during a knitted process. The produced connecting points must satisfy all requirements with respect to optical impression and support comfort.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a method of connecting two knitted parts on a flat knitting machine, which is a further improvement of the known methods.
In keeping with these objects and with others which will become apparent hereinafter, one feature of present invention resides, briefly stated in a method of connecting two knitted parts on a flat knitting machine with at least two opposite needle beds, a needle racking device and a machine take up device, in which the both knitted parts are suspended over in neighboring needles of one needle bed and subsequently the stitches of one knitted part are further suspended over by so many needle distances in direction to the other knitted part that both corresponding bordering stitches come together on one needle and are knitted off jointly, before a new suspended over of the stitches of one of the knitted parts is performed by so many needle distances that the bordering stitches are overlapped and knitting off of the bordering stitches is performed, and this process is repeated until all stitches of both knitted parts are connected with one another.
The knitted parts can be suspended over preferably in alternating order in direction toward the other knitted article. This method can be used for knitted parts in all binding and pattern types. Since the connecting seam must be flat and does not project from the connected knitted parts, the connecting knitting row is single-layered.
During connection of multi-layered knitted parts, they can be provided before the suspension near one another on a needle bed with a single-layered end row. For knitted parts which are produced by sectors alternatingly on one or both needle beds, the stitches can be so suspended over, that all stitches are located on one needle bed. With the use of the inventive method it is possible to produce connecting seams which extend vertically, horizontally, or at any desired angle.
The drawings illustrate the formation of a connecting seam between knitted parts over a needle which correspond to the finest possible connection. With the same method it is also possible to produce connecting seams via several knitting needles, as desired in view of the pattern or for producing a special connecting affect.
The novel features which are considered as characteristic for the present invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
