WE SHAPE CHAINETTES ON ALL THE NEEDLES OF THE TRADE, BY MAKING LONGITUDINALLY A COMBINATION OF CHAINETTES 1A OF INEXTENSIBLE THREADS MESH 1 AND OF ELASTIC CHAIN THREADS 2 NOT MESHED BUT INTERLACED WITH INEXTENDED CHAINETTES AND ELASSIBLE THREADS, TRANSMISSION, 1A 3 GUIPES WITH AT LEAST ONE INEXTENSIBLE WIRE 3B, THE TRANSVERSE WIRES 3 EXTENDING OVER AT LEAST TWO CHAINETTES 1A WHICH ARE CONNECTED AND ASSEMBLED BY THESE TRANSVERSE WIRES. THE INVENTION IS IN PARTICULAR USED TO MAKE BANDAGES.

Description

The subject of the invention is an elastic compression strip

all sense.

  The object of the invention is related to the technical sector of care, hygiene, bandages for the human body and for

animals.

  Some of the so-called "elastic bands", in spite of the interest and advantages they offer, often present in a more

  exactly the same, deformation capabilities under

  angles, by the addition of the multiple effects of deformation of the meshes These bands are elastic in certain directions or under

  some angles of stretching, and deformable in other directions.

  According to the invention, it has been desired to produce a strip of

  which is really elastic in all directions, that is to say, which makes the stretching of the elastic threads

  whatever the angles of effort under which the band is

  However, the band according to the invention has a limited extensibility which can not be exceeded, and this extensibility

  can be planned and organized according to the therapeutic needs.

  The band of contention elastic in all directions according to the invention

  It has a mesh structure which is advantageously manufactured with a high yield, on needle knitting machines of the type

  Rachel, and it is characterized by the formation of links

  on all the needles of the trade, realizing longitudinal

  a combination of inextensible mail chains

  strips and elastic warp threads, not meshed, but intertwined

  with the inextensible chains, and using, transverse

  Elastic threads covered with at least one inextension yarn

  cross-threads extending over at least two chains

  which are connected and assembled by these transverse wires.

  According to another characteristic, the stretched elastic warp yarns are woven when the meshes are formed, so that

  produced, after manufacture, a retraction of the inex-

  tensibles. These and other characteristics will emerge from the

description which follows.

  In order to fix the object of the invention, without however limiting it, the single figure of the drawing shows, on a greatly enlarged scale for the understanding, the technical graphic drawing of an embodiment

  of a fraction of the compression band according to the invention.

  The band is designated in the set by (A) This band is

  following year of the sons considered in their nature and in their work

  the threads (1) are inextensible threads that work with all

  the needles of the trade to form long-lasting chains

  These threads may be threads of cotton, viscose,

  or other suitable inextensible wires.

  the yarns (2) are extensible longitudinal yarns that are not meshed but interlaced with the chains (la). These elastic yarns are gum or elastomer yarns of any known type which are not

usually not wrapped.

  the son (3) are extensible transverse son which extend at least on two chains (la), and on three chains in the exemplary embodiment illustrated These son work and are connected and assembled with the chains (la) at the known way of a

  important way and as we see at the bottom and right at the bottom right

  According to the drawing, the extensible threads (3) consist of a yarn / extensible yarn (3a) covered with at least one inextensible yarn (3b). The yarns (3a) are elastic yarns made of rubber or elastomer, and the

  non-extensible threads (3b) are of cotton, viscose or otherwise.

  In the embodiment illustrated in the drawing, there is shown a grid whose vertical lines (B) schematically show the general work of the needles of the trade (not shown), while the horizontal lines (C) schematically show the rows

  It is intended that the extensible longitudinal yarns (2) are woven stretched so that after manufacture, at the exit of the loom, the inextensible yarn chains (1) are retracted to give the band an embossed, granular appearance which promotes adhesion. In the mesh structure of this band, by modifying the dimension in section (denier) of the threads, their type and quality,

  contention tapes corresponding to

  different therapeutic possibilities and possibilities.

  The advantages and possibilities given by the band of

  according to the invention are the following:

  as a result of the regularity and characteristics of the structure

  mesh, the pressure printed by the band is regular over its entire width, which avoids localized restrictions, by the effect of its particular mesh structure, the band is ventilated and it avoids maceration under the band, meeting the requirements of comfort and temperature The band is flexible,

  whatever its strength, and it does not hinder free play.

  eyelid (which is important so as not to increase the risk of ankylosis of the ankle for example) The band is light and thin

  and it makes it easier to put on footwear for ambulatory patients.

  avoid excessive thicknesses.

  the band is really stretched in all directions by stretching the threads. It deforms when it is put in place and it conforms well to the anatomical relief. After removal of the band, in the
