Embodiment Construction

[0043] Such as figure 1 As shown, the looping machine has the general form of a sewing machine and comprises a body 2 with a swan neck 3 in the upper part and a plate 4 in the lower part. The nose 3a of this swan neck contains part of the mechanism of the needle 5 and supports the figure 2 with 3 Different devices are described. Plate 4 is extended by a housing 6 containing means for moving forward the reels N1 and N2 to be connected. The unit is protected by removable covers 7, 8 and 9, which are in figure 2 is removed.

[0044] in detail figure 2 Before the different sections presented in , it is necessary to mention image 3 , which shows an embodiment of a frame 11 carrying the sewing mechanism C (ie, the needles and their hooks and their drive means).

[0045] According to the invention, this frame 11 is formed by a metal frame 10 having a flat U-shape with its upper arm 10a extending horizontally and equipped at its free end with a downwardly vertical appendage...

Abstract

In the machine of the invention, the means ensuring the relative lap-needle displacements, in the horizontal plane and upon each new stitching through the laps N1 and N2, include: belts 50a, 50b ensuring the displacement of the laps to be assembled N at least in one direction and along the sewing direction X only; and means 15, 16, 17 ensuring the displacements in both directions, and along the direction Y only which is perpendicular to the sewing direction X, of a carriage 11 bearing the sewing mechanism C, i.e. a needle 5 and a hook 20; wherein said displacement means are independent from each other but are controlled and commanded by the same processing and control unit so that the stitching position of each mesh to be stitched results from the displacement of the laps (N1, N2) in the sewing direction X only and from the displacement of the sewing mechanism (C) in the Y direction only.

Description

technical field [0001] The present invention relates to a looping machine for joining reels of porous structure by means of a thread which passes through the apertures of an upper reel and is connected to a lower reel, whether the apertures are made of mesh fabric, The weft / warp interweaving of the threads, or defined by the gaps between the threads randomly arranged on the mat. Background technique [0002] The prior art provides a number of looping machines which can be used in the garment industry for joining one knitted panel to another, such as a U-folded loop in which the edge of a knitted panel is clamped. In this looping operation, it is necessary to align each mesh of the edge row of the sheet to be attached with the vertical trajectory of the needles carrying the looping thread of the lower roll. [0003] To ensure this uniformity of the meshes, either use a plurality of combs on whose teeth the meshes must be placed manually in a low-productivity manner; or use a...
