• the second tubular element 5 comprises a second front portion 5c corresponding to at least one mesh, preferably at least three meshes, disposed (s) on the front needle bed 31; and a second posterior portion 5d corresponding to at least one mesh, preferably at least three meshes disposed on the rear needle 32, said second portions 5c and posterior 5d being disposed at the lower end 5b of the second element tubular 5 as shown in Figure 6.
• first anterior portion 4c and the second anterior portion 5c knitted overlap on at least one mesh, in this specific example on three meshes, said first 4c and second 5c anterior portions n not being overlapped by the first 4d and second 5d posterior portions.
• first posterior portion 4d knitted and the second posterior portion 5d knitted overlap on at least one mesh, in this specific example on three meshes, and said first 4d and second 5d posterior portions are not overlapped by the first 4c and second 5c anterior portions.
• a compression glove 2 is thus obtained in which the first tubular element 4 and the second tubular element 5 are joined according to a first knitted connection zone (4c, 5c) and a second knitted connection zone (4d, 5d), which is distinct. of the first knitted connection zone (4c, 5c), each of said first and second knitted zones consist of a knitted layer.
• the junction between the tubular elements of the compressive effect article is thin and comfortable for the user.
• the tubular elements can be knitted in jersey "all hands", which allows to obtain a thin gauge, and thus a better control of the pressure exerted and the size of the article 1.
• the charged meshes formed with the second elastic thread 33 are consecutive without forming looped meshes, which advantageously makes it possible to control the elasticity of the knitted piece 3.
• compression articles according to the invention thus advantageously have a fine gauge, that is to say a number of columns of mesh per cm greater than or equal to 8 and less than or equal to 15, in particular less than or equal to 13 while allowing to control the desired elasticity and compression.
• Compression articles according to the invention can also be made to measure and in various sizes, or very small, for compression items for children or even young children.
