DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0057] With particular reference to FIGS. 1A, 1B, 1C, these illustrate three distinct steps of the procedure for manufacturing an undershirt 1, of the type provided with a trunk, two long sleeves and a collar, according to the invention.

[0058] The procedure involves the use of a circular knitting machine with seamless technology.

[0059] The first step of the procedure concerns the construction, with said machine, of a first tubular element 10 in cylindrical fabric.

[0060] To facilitate the description and with reference to the final garment, said first tubular element 10 comprises a front side 11, a rear side 12, an upper edge 13 and a lower edge 14.

[0061] Said machine, interacting with a graphic program used to design the garment, creates on said first tubular element 10, during its construction step, structured areas (not illustrate) with particular features of elasticity and compression, and draws a plurality of cutting lines (FIG. 1A).

[0062] With particular reference to FIG. 1A, representing a type of T-shirt 1 also schematized in FIG. 2, said cutting lines are defined as follows:

[0063] a first 31, a second 32, a third 33 and a fourth 34 cutting line are positioned longitudinal to the length of said first tubular element 10, between said lower edge 14 of said first tubular element 10 and an intermediate portion thereof, thus without reaching its upper edge 13; where said first 31 and said second 32 cutting line belong to the front side 11 of said first tubular element 10, while said third 33 and said fourth 34 cutting line belong to the rear side 12 thereof;

[0064] a fifth 35 and a sixth 36 cutting line, each starting from the upper edge 13 of the front side 11 of said first tubular element 10, descending towards said lower edge 14 and rising again to end on the upper edge 13 of the rear side 12 of said first tubular element 10.

[0065] In a variant not illustrated, said first 31, second 32, third 33 and fourth 34 cutting line have an overturned elongated V shape. Each V shaped cutting line starts from a point that will define the underarm point to then open out towards the lower edge 14 of said first tubular element 10.

[0066] The second step of the procedure, illustrated in FIG. 1B, relates to cutting said first tubular element 10 along said cutting lines 31, 32, 33, 34, 35, 36 to separate portions of fabric, to create flaps of fabric belonging to the front side and to the rear side of said first tubular element. In this step the excess material deriving from cutting said first tubular element 10 along said fifth 35 and sixth 36 cutting line, i.e. the portions of fabric between said fifth 35 and sixth 36 cutting line and the upper edge 13 of said first tubular element 10, is also eliminated.

[0067] If said first 31, second 32, third 33 and fourth 34 cutting line have an overturned elongated V shape, the further excess material, between said cutting lines 31, 32, 33, 34 and the lower edge 14 of said tubular element 10, is to be eliminated.

[0068] Advantageously, during construction and drawing of the tubular element, the machine can be programmed to reduce the amount of yarn used in the areas outside the cutting lines, so that the excess material, which will subsequently be eliminated, is less and of lower quality, to obtain a further saving of raw material.

[0069] The third step of the procedure, illustrated in FIG. 1C, concerns stitching the flaps of the portions of fabric obtained with said cutting lines 31, 32, 33, 34, 35, 36 to manufacture said undershirt 1 and in particular to create the two sleeves, the trunk and the shoulders.

[0070] FIG. 1C then illustrates the manufactured undershirt 1, where in particular the following can be observed:

[0071] a first seam 51, which starts and ends on the lower edge 14, adapted to join the flaps obtained with said first 31 and said third 33 cutting line to create the right sleeve and the right side of the trunk of said T-shirt;

[0072] a second seam 52, which also starts and ends on the lower edge 14, adapted to join the flaps obtained with said second 32 and said fourth 34 cutting line to create the left sleeve and the left side of the trunk of said T-shirt;

[0073] a third seam 53 adapted to join the flap belonging to the front side 11 of said first tubular element 10 with the flap belonging to the rear side 12 of said first tubular element 10 obtained with said fifth 35 cutting line to create the right shoulder of said T-shirt;

[0074] a fourth seam 54 adapted to join the flap belonging to the front side 11 of said first tubular element 10 with the flap belonging to the rear side 12 of said first tubular element 10 obtained with said sixth 36 cutting line to create the left shoulder of said T-shirt.

[0075] FIG. 2 schematically represents the construction step of a T-shirt according to the procedure illustrated by FIGS. 1A, 1B and 1C, while FIG. 3 schematically represents the construction and drawing step of the cutting lines for a further type of undershirt 1, in particular for a “mock turtleneck” T-shirt, i.e. with a high neck. The manufacturing procedure is identical to that described above, but said fifth 35 and sixth 36 cutting line are shaped differently and descend in more depth towards the lower edge 14 of the tubular element 10.

[0076] With particular reference to FIGS. 4A, 4B and 5, these schematically illustrate the step of construction, of drawing the cutting lines and of stitching for a further type of undershirt 1, in particular for a V-neck T-shirt with short sleeves.

[0077] For said variant, the first step of the procedure concerns the construction, with said machine, of a first 10 and of a second 20 tubular element in cylindrical fabric.

[0078] In the same way as said first tubular element 10, said second tubular element 20 also comprises a front side 21 (part of FIG. 4A), a rear side 22 (part of FIG. 4B), an upper edge 23 and a lower edge 24.

[0079] With reference to FIGS. 4A and 4B, these show the cutting lines defined as follows:

[0080] a first 31, a second 32, a third 33 and a fourth 34 cutting line are positioned longitudinal to the length of said first tubular element 10, between said lower edge 14 of said first tubular element 10 and its intermediate portion, without reaching the upper edge 13, where said first 31 and said second 32 cutting line belong to the front side 11 of said first tubular element 10 while said third 33 and said fourth 34 cutting line belong to the rear side 12 thereof;

[0081] a fifth 35 and a sixth 36 cutting line, each starting from the upper edge 13 of the front side 11 of said first tubular element 10, descending towards said lower edge 14 and rising again to end on the upper edge 13 of the rear side 12 of said first tubular element 10;

[0082] a seventh cutting line 37 extends along said upper edge 13 of said first tubular element 10 and has a profiled shape, moving away from and towards said upper edge 13 to define the V shape of the collar;

[0083] an eighth 38 and a ninth 39 cutting line are positioned transverse to the length of said first tubular element 10, between said first 31 and said third 33 cutting line and between said second 32 and said fourth 34 cutting line, respectively;

[0084] a tenth 40 and an eleventh 41 cutting line, positioned longitudinal to the length of said second tubular element 20, between its lower edge 24 and its upper edge 23, where said tenth cutting line 40 belongs to the front side 21 of said second tubular element 20 while said eleventh cutting line 41 belongs to the rear side 22 thereof.

[0085] The subsequent step concerns the operation of cutting said first 10 and said second 20 tubular element along said cutting lines 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 to separate portions of fabric.

[0086] Moreover, the excess material deriving:

[0087] from cutting said first tubular element 10, i.e., the fabric between said fifth 35, sixth 36 and seventh 37 cutting line and the upper edge 13 of said first tubular element 10, and between its lower edge 14 and said first 31, second 32, third 33, fourth 34, eighth 38 and ninth 39 cutting line;

[0088] from cutting said second tubular element 20, i.e. the fabric between said tenth 40 and eleventh 41 cutting line and its upper 23 and lower 24 edges; is eliminated.

[0089] With reference to FIG. 5, this illustrates the step of stitching the flaps obtained with said cutting lines, to manufacture said T-shirt 1 and, in particular, the seams 51, 52, 53 and 54 will be created to create the two short sleeves M, the trunk T and the shoulders, while the seam 55 will be created to produce the ring that will define the V-shaped collar, once attached to said first tubular element 10 with further stitching.

[0090] The undershirt according to the invention can be created in any size, using a machine with a suitable diameter of cylinder and knitting a first tubular element of suitable length.
