Hereinafter, the most preferred embodiment of a knitted fabric having an arcuate knitted portion at least partially in a peripheral edge portion and a method for knitting the same will be described with reference to the drawings.

First Embodiment

Fig. 1 is a side view of a knit hat which is an embodiment of a knitted fabric having an arcuate knitted portion at least partially in a peripheral edge portion according to the invention. In the drawing, reference numeral 1 denotes an entire hat, 2 denotes a pouch-shaped knitted portion, 3 denotes a strap-shaped knitted portion, 4 denotes a peripheral edge portion of a pouch-shaped knitted fabric portion, 5 denotes lines connecting junction points of the pouch-shaped knitted fabric portion, 6 denotes an opening, 7 denotes a central portion of the pouch-shaped knitted portion, 8 denotes arrows illustrating knitting directions, 9 denotes a junction portion of strap-shaped knitted portions at both sides, 10 denotes a hat inlet portion and 11 denotes a set-up portion.
The hat 1 is knitted with a known weft knitting machine (not illustrated) having at least one pair of front and rear needle beds disposed so that end portions thereof are close to each other. The needle beds each house a knitting needle to be slidable back and forth.
The hat 1 is formed by the pouch-shaped knitted portion 2 and the strap-shaped knitted portion 3. The pouch-shaped knitted portion 2 has the arcuate peripheral edge portion 4 and gathers to the central portion 7 from the peripheral edge portion 4. The strap-shaped knitted portion 3 forms the inlet portion 10 and the opening 6 of the hat 1.
As illustrated in Fig. 2, the pouch-shaped knitted portion 2 and the strap-shaped knitted portion 3 are formed from a set-up portion 11 (i.e., the peripheral edge portion 4 of the pouch-shaped knitted portion 2) which is common to front and rear knitted fabrics. The set-up portion 11 common to the front and rear knitted fabrics is formed with a knitting yarn fed from a single yarn carrier (not illustrated) to the front and rear knitting needles of the needle beds.
Alternatively, the set-up portion 11 may be formed with a knitting yarn fed to a knitting needle of either of the front or rear needle bed and a loop moved toward an opposite knitting needle.
Setting-up width is calculated by adding a length of the arcuate peripheral edge portion 4 to the width of the strap-shaped knitted portion 3 of the hat 1.
As described later, Fig. 2 is one of expanded plan views of the knitted fabrics knitted from the set-up portion 11 at both the front and rear needle beds. For example, Fig. 2 is an expanded plan view of the knitted fabric knitted at the front needle bed.
Next, from the set-up portion 11, knitting yarns are fed through the knitting needles of the front and rear needle beds from the individual yarn carrier corresponding to each needle bed. Knitting width is reduced at a plurality of areas other than the strap-shaped knitted portions 3 described below located at both ends of the knitting width of each needle bed. Accordingly, a plurality of isosceles triangles having each apex gathering to a central portion A of the knitted fabric width illustrated in Fig. 2 is formed.
Conversely, the lines 5 which connect the wales and the junction points extend radially from the central portion A of the knitted fabric width.
Although a plurality of isosceles triangles having apexes gathering to the central portion A of the knitted fabric width were formed in this first embodiment, the invention is not limited to the same. Configurations other than isosceles triangles may alternatively be provided by changing the positions and numbers of the junction points. A plurality of isosceles triangles having apexes gathering to the central portion A of the knitted fabric width are not necessarily of the same configuration. Alternatively, different isosceles triangles or configurations other than isosceles triangles may be employed.
The knitting width is reduced at a plurality of areas in the following manner. As illustrated by arrows 8, stitches at a plurality of areas are made to overlap each other near the central portion A of the knitted fabric width and new stitches are formed in the knitting needle over the overlapping stitches.
In this manner, the knitting width is reduced at a plurality of areas and gathers to the central portion A of the knitted fabric width illustrated in Fig. 2, the strap-shaped knitted portions 3 are disposed to be adjacent to each other with the central portion A disposed therebetween.
The thus-disposed adjacent strap-shaped knitted portions 3 are knitted with the stitches thereof overlapping each other. Accordingly, when strap-shaped knitted portions 3 of both sides are connected at the junction portion 9, side edge portions of the strap-shaped knitted portions 3 form an opening as the inlet portion 10 of the hat 1. In this manner, the hat 1 (i.e., a pouch-shaped knitted fabric) having a smoothly-curved set-up portion 11 is provided.
The inlet portion 10 of the hat 1 is formed by the side edge portions of the strap-shaped knitted portions 3 to provide a soft, flexible and beautiful knit hat 1 as compared with welt-stitched ones.
Although not illustrated, stitch patterns, such as a garter stitch and a lace stitch, may be formed in the strap-shaped knitted portions 3 to provide the hat 1 with a significantly increased design value.
