DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a new knitting process and a new knitting machine for producing garments comprising a body section or panty section and a pair of legs, as for example tights, leggings and similar products. The invention also relates to a product produced by this method.
BACKGROUND ART
The conventional method of producing knitted garments of the above type involves firstly producing two tubular articles one after the other on a circular knitting machine, and secondly sending these to a machine which cuts them and sews them together, forming the body section or panty section of the finished garment in the joining zone.
This process is long and complicated, in that it requires the semifinished material to be passed through more than one machine, involves a large proportion of labour and produces offcuts, so that yarn which has already been knitted is wasted.
Systems have therefore been devised for knitting tights and suchlike articles of the above type in a single knitting operation. Examples of these techniques are described in the following patents: U.S. Pat. No. 5,020,340, U.S. Pat. No. 5,127,240, U.S. Pat. No. 5,226,297. Systems of more recent production are described in WO 95/00689 (PCT/IT94/00087), WO 95/01473 (PCT/IT/94/00099). These systems are, however, highly complex.
OBJECTS OF THE INVENTION
It is an object of the present invention to provide a method and a machine for the production, in a single productive operation, of a knitted garment comprising a body section and two legs joined to said body section, which method and machine are simpler, more reliable and easier to operate than the methods and machines known hitherto.
In particular, one object of the present invention is to provide a production method and a machine of the aforesaid type that are fast and reliable and result in an article of pleasing appearance.
Another object of the present invention is to provide a textile knitting machine capable of producing a finished or almost finished article (with legs and body section) and that has a relatively small number of moving parts, with low inertias.
Yet another object of the present invention is to provide a method and a machine that can produce an article of the abovementioned type that is very strong.
An object of a further embodiment of the present invention is to provide a machine that can produce tights or similar products with the toes of the legs already closed, avoiding the need for closure in a separate stage.
Yet another object of an embodiment of the present invention is to provide a knitting method and a knitting machine that can produce articles in which the same yams form both the legs and the body section without any interruption.
These and other objects and advantages of the present invention will be clear to those skilled in the art on reading the following text.
SUMMARY OF THE INVENTION
The method according to the invention involves forming a complete garment or article, consisting of a body section and a pair of legs, in a single uninterrupted operation comprising the following stages: beginning with the lower ends of the legs, on two hosiery cylinders with needles arranged next to each other; and body section closure zone, and completing said body section by the combined action of the cylinders and rectilinear beds of needles.
In the second stage of the operation the yarns already employed in the first stage may be the only ones that continue to be used, or, at the operator's choice, other yarns may be added to or substituted for them.
The method is realized by an original combined use of elements characteristic of two circular (or cylindrical) hosiery machines with elements characteristic of a rectilinear knitting machine; of which the first work initially on their own and subsequently in cooperation and in combination with the activity of the second.
The advantages of this are obvious, and include: the possibility of replacing yarns of a given quality with others of a different quality in the course of the operation and w
