Benefits of technology

The invention prevents wrinkle formation in sewn articles by creating a seam along a curved line using a continuous flexible member. The seam is shaped by the first curve formed by the flexible member and doesn't deform the fabric of the tubular knitted article in the area where the seting machine acts, thanks to the deflector profile. This results in a smoother, more uniform seam.

Problems solved by technology

Due to the way in which the curved profile is formed, in the sewn tubular knitted article wrinkles form at the seam line, which can make the garment somewhat uncomfortable.

Embodiment Construction

[0025]The following detailed description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. Additionally, the drawings are not necessarily drawn to scale. Also, the following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims.

[0026]Reference throughout the specification to “one embodiment” or “an embodiment” or “some embodiments” means that the particular feature, structure or characteristic described in connection with an embodiment is included in at least one embodiment of the subject matter disclosed. Thus, the appearance of the phrase “in one embodiment” or “in an embodiment” or “in some embodiments” in various places throughout the specification is not necessarily referring to the same embodiment(s). Further, the particular features, structures or characteristics may be combined in any suitable manner in one...

Abstract

The device (1) comprises a continuous flexible member (7), configured and arranged to press with a branch thereof an end portion of the tubular knitted article (G1, G2) against a supporting surface (31) and to feed the tubular knitted article (G1, G2) along a feed path from an insertion position toward and through a sewing area in which there is arranged a sewing machine (5). In the insertion area the portion of continuous flexible member in contact with the tubular knitted article (G1, G2) forms a first curve (7A; 7B). In the sewing area, the continuous flexible member (7) co-acts with a convex deflector profile (25), which imparts to the continuous flexible member (7) a curvature with a convexity facing the same part as the convexity of the first curve (7A; 7B) of the continuous flexible member (7).

Description

FIELD OF THE INVENTION[0001]A device is disclosed for closing, by means of sewing, a toe of a tubular knitted article, such as a sock, a stocking, or a leg of a pantyhose. Also disclosed is a method for closing, by means of sewing, the toe of a tubular knitted article.BACKGROUND ART[0002]In the hosiery industry, it is known to produce tubular knitted articles, such as stockings or socks, on a circular knitting machine, and to unload the complete tubular article, with an open end or toe, intended to be closed by means of sewing in a subsequent processing step. In some cases, the tubular knitted article is a leg of a more complex garment, in particular a pantyhose. The garment can be formed by two legs and by a body that can in some cases be knitted in a single operation on a knitting machine. According to more conventional methods, the garment is produced by joining two legs, formed by respective tubular knitted articles produced separately to one another. In some cases, the toe of t...
