Luxembourg formed by: "sogilo" for: "Method of manufacturing a pile mesh fabric, machine for its implementation and fabric thus produced".

Λ Ιά 2 * ►

The present invention relates to a method of manufacturing a pile mesh fabric in which a fabric is knitted using a knitter, fibers are incorporated into the forming mesh from a fiber distributor device located on one side of the knitting needles and the fibers are blown in the direction away from the distributor device and going towards the needles and beyond.

Processes of this kind are carried out in particular by means of circular knitters provided with fiber distributing devices situated outside the knitting machine and nozzles also situated outside the knitting machine and blowing air at from the outside to the inside of the needle bed.

A process of this kind is known according to American Patent No. 3,226,952.

According to this known process all the fibers, which are incorporated in the fabric formed / stand on the latter in the direction of the interior of the circular knitter.

It is an object of the invention to provide a process for providing a fabric of another aspect, in which the fibers are not drawn up on the mesh fabric but rather are embedded in the mesh.

The straight fibers of fabrics produced by known methods do not all have the same height relative to the plane of the stitches. They must therefore be cut to the same length, so that the pile fabric has a flat upper surface. This is achieved by shaving. A relatively large percentage of the weight of the fibers supplied to the knitter is thus lost to the final product, which disadvantageously influences the cost price.

The invention also aims to remedy this drawback.

To this end, the fibers incorporated in a row of stitches are blown in a direction opposite to the above-mentioned direction, before a new row of stitches adjacent to the first is knitted.

The invention also relates to a machine for carrying out the process defined above.

In this respect the inventio.n relates to a machine for making a pile mesh fabric comprising means for making a mesh fabric from a thread, means for directing fibers towards these means for making the fabric mesh and incorporating these fibers into the forming mesh and a nozzle distributing a stream of air over the fabric forming in the direction from the means directing the fibers to the means making the fabric.

A machine of this kind is known according to American Patent No. 3,226,952.

This known machine necessarily produces a fabric of which all the fibers stand on the same face of the fabric.

The object of the invention is to provide a machine making it possible to produce a fabric the fibers of which do not stand on one of its faces, but lie roughly in the plane of the meshes.

To this end, the machine according to the invention comprises at least a second nozzle directed in the opposite direction to the first and disposed downstream of the place where the fibers are incorporated into the fabric.

The invention also relates to the pile mesh fabric produced by the process defined above.

The fabric according to the invention is characterized * in that the fibers held by a mesh of a row are also held by a corresponding mesh of at least one adjacent row.

Other details and particularities of the invention will emerge from the description of a process for manufacturing a pile mesh fabric, a machine for its implementation and a fabric thus produced according to the invention, given below by way of nonlimiting example and with reference to the attached drawings.

Figure 10 is a plan view of part of the pile mesh fabricated on the machine according to the preceding figures.

In the different figures, the same reference notations designate identical elements.

The machine for manufacturing a knitted fabric, parts of which are shown in Figures 1 and 2 is a circular knitter combined with a device. feeding fibers to be incorporated into the mesh fabric.

Circular knitters of this kind are known from US Patent No. 3,226,952.

Only the elements necessary for the understanding of the present invention have been represented and are described below.

Said circular knitter comprises a bed of needles 1 and plates 2 which participate in the rotary movement of the cylinder 3. This mobile cylinder 3 which carries the needles which can undergo a vertical movement in this cylinder receives a rotary movement relative to the fixed cylinder 4 around their common geometric axis. The fixed cylinder 4 comprises means for guiding the pins of the needles, the latter thus undergoing a vertical movement of up and down during their rotary movement with the mobile cylinder 3. The guide 5 which is fixed relative to the fixed cylinder 4 imposes a radial movement to the plates 4 while the latter participate in the rotary movement of the movable cylinder 3. This radial movement is considered as an advance when the plate approaches the geometric axis of the cylinders 3 and 4 and as a recoil when the plate s away from this axis.

The eye of each needle is closed by a tongue 14 when the latter is in the closed position shown in Figures 7 and 9. The eye of the needle is opened when the tongue 14 is in its open position shown in Figures 5 , 6 and 8. In this position the 6 hook 16 of the needle 1 can capture either the thread 6 brought by the thread guide 7, or tufts of fibers 13 brought by the felling comb 8 forming the last element of the fiber feeding device.

A pipe 10 for supplying compressed air is carried by the fixed cylinder 4. This pipe 10 supplies compressed air to the nozzles 11, the position of which is determined below.

c The circular knitter described so far and partly shown in Figure 1 does not differ from the circular knitters known for the formation of pile fabrics.

The circular knitting machine according to the invention and partly shown in FIG. 2 comprises, in addition to the aforesaid nozzles 11 blowing air from the outside towards the inside of the cylinder formed by the bed of needles 1 also from the nozzles 12 The latter are also supplied with compressed air through line 10 and blow air through the needle bed from the inside of the cylinder constituted by the needle bed to the outside. The arrangement of these nozzles is also described below.

The needle bed extends continuously around the periphery of the movable cylinder 3 and moves with this cylinder. The circular knitter comprises several systems mounted with respect to the fixed cylinder 4 and each composed in particular of a device for feeding fibers ending in a felling comb 8, a thread guide 7, means for guiding the needles 1 in their vertical movement, means for guiding the plates 2 in their radial movement, of a nozzle 11 and a nozzle 12. The different systems = operating in an identical manner, the operation of a single system is described below. The guide means being known, only their effect, i.e. the movement of the stages and the hands is described. The needles 1 and the plates 2- have r 7 displacement relative to the fixed cylinder 4 in the direction of the arrows 15. The needles and the plates successively occupy 1 <positions represented in FIGS. 5 to 9.

A needle 1 and a plate 2 arriving with the movable cylinder 3 in the position indicated by the line V-V to the right of FIG. 3 occupy the positions shown in FIG. 5.

The needle 1 then occupies its upper position.

A mesh of the preformed fabric is held on the lower part of the needle rod 1 by the plate 2 which is in its advanced position. The tongue 14 is in its open position and the hook 16 of the needle 1 captures a tuft of fibers 13 brought by the cylinder 8 forming a felling comb. Arrival in the position indicated by 17 in FIG. 3 the plate moves back to occupy the position indicated in FIG. 6 representing the relative arrangement of the elements when the needle 1 and the plate 2 have arrived at the place indicated by the line VI- VI in Figure 3.

Between this location and the location indicated by line VII-VII in Figure 3 the needle 1 descends until it occupies the position shown in Figure 7. At this location the tongue 14 is brought into its position closing. The fibers 13 are then incorporated into the preformed stitch still remaining on the needle. The latter then passes in front of the nozzle 11 which directs an air jet towards the needle bed from the outside of the bed towards the inside. As can be seen in FIG. 4, the tuft of fibers 13 is thus directed inward, therefore on the side of the nozzle 12 and on the side opposite to the nozzle 11.

The plate 2 advances at the place indicated by the reference 18 to a position in which it maintains both the mesh formed last and the tuft.

The mesh and the tuft of fibers being maintained, the needle 1 rises and the tongue 14 returns to its open position. Arrived at the place indicated by the line VIII-VIII in Figure 3, 8 the different elements occupy the position shown in Figure 8.

At the place indicated by the reference 19 the plate 2 moves back, thus releasing the preformed mesh and the tuft of fibers 13 incorporated therein. From the same place the needle 1 having captured the wire 6 descends. The tongue 14 comes into its closed position and when the needle 1 has reached its lower limit position, at the place indicated by the line IX-IX, a new mesh has formed and the various elements occupy the position shown in Figure 9.

The needle continuing its path in the direction of arrow 15, the plate 2 advances to the place indicated by the reference 20 in FIG. 3. The plate consequently maintains the newly formed mesh.

Continuing its path, still in the direction of arrow 15, towards the following system, the needle passes in front of a nozzle 12 blowing from the inside of the cylinder constituting the needle bed towards the outside, as it can be seen in Figures 2 and 4.

The tufts of fibers which are incorporated into the newly formed meshes at the location indicated by line IX-IX have protruding parts on the mesh fabric. Before entering the zone of influence of the nozzle 12, these parts are directed towards the inside of the cylinders. Passing in front of the nozzle 12, these parts receive a push towards the outside of the needle bed following the air current caused by the nozzle 12. Said parts of the fibers are carded by the felling comb at the same time as the freshly fibers admitted. When the needle is mounted to the place indicated by the line VV on the left of FIG. 3 and receives its upward and downward movement from the following system, it incorporates at the same time in the meshes which are formed by the new system fibers freshly admitted by the comb 8 and the parts of the fibers protruding from the meshes formed by the previous system.

* 9

The new system functions like the system whose operation has just been described.

As a result, the fibers are not erected on the mesh fabric, but are imbricated in the mesh as shown in Figure lO, showing the mesh formed by the son 6 and the fibers 13 incorporated in the plane of the fabric.

It follows from the above that according to the invention is blown, through the nozzle 12, the fibers incorporated in a row of stitches in a direction opposite to that which they 'previously received, before a new row of adjacent stitches at the first be knitted.

It should be understood that the invention is in no way limited to the embodiment described above and that many modifications can be made to it, in particular as to the form, number and arrangement of the elements involved in its production without going beyond the scope of this patent application.
