US 2021/0372019 A1 · DEVICE AND METHOD FOR SEWING THE TOE OF A TUBULAR KNITTED ARTICLE

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).

A device for sewing a toe of a tubular knitted article, the device comprising:

a continuous flexible member comprising a branch, said continuous flexible member being configured and arranged to press an end portion of the tubular knitted article with the branch against a supporting surface and to feed the tubular knitted article along a feed path from an insertion position toward and through a sewing area, wherein a sewing machine is arranged for sewing the toe of the tubular knitted article, wherein the branch of the continuous flexible member forms a curve in the insertion position wherein the continuous flexible member co-acts with a convex deflector profile in the sewing area, wherein the convex deflector profile forms a curvature in the continuous flexible member, the curvature comprising a convexity facing on a same side as a convexity of the curve of the continuous flexible member.

A method for sewing a toe of a tubular knitted article, the method comprising the steps of:

engaging the tubular knitted article in an area of the toe of the tubular knitted article between an opposing surface and a continuous flexible member, the continuous flexible member forming a curve in an engaging area, the curve comprising a convexity facing the toe of the tubular knitted article;
the tubular knitted article via the continuous flexible member along an opposing surface toward a sewing area, imparting to the toe of the tubular knitted article an inverse curvature with respect to the curve of the continuous flexible member in the engaging area;
sewing the toe of the tubular knitted article via a sewing machine by feeding the toe of the tubular knitted article through a sewing area via the continuous flexible member, the continuous flexible member being curved in the sewing area according to a curvature having a convexity facing a same side as the curve of the continuous flexible member.
