The invention relates to the field of flat knitting machines. The invention in particular pertains to a knitting method for a flat knitting machine comprising one or more needle beds. The invention also relates to a flat knitting machine comprising one or more needle beds, the machine comprising a plurality of storage elements capable of storing at least one mesh.
BACKGROUND OF THE INVENTIONOn a flat knitting machine comprising one or more needle beds, a typical knitting method consists of using certain needles to store previously formed knit meshes temporarily. Storing meshes thereby makes it possible to free other needles to then use those freed needles for other knitting operations. The problem that arises is that, during these time periods when meshes are stored on certain needles, the latter cannot be used to perform other knitting operations.
BRIEF DESCRIPTION OF THE INVENTIONA first aim of the knitting method according to the invention is to make it possible, in a flat knitting machine comprising one or more needle beds, to free each of the needles from their meshes, so as to be able to use the freed needles to perform other knitting operations, while allowing the meshes to return to the needles from which they were previously freed. A second aim of the knitting method according to the invention is to make it possible to eliminate the presence of meshes between the needles. A third aim of the knitting method according to the invention is to make it possible, in the case of a flat knitting machine comprising several beds, to free the space between the beds. A fourth aim of the knitting method according to the invention is to make it possible to decrease the tension on the stored meshes. A fifth aim of the knitting method according to the invention is to make it possible to better avoid mixing between the fibers of the stored meshes and the fibers of the knitted meshes.
In the knitting method for a flat knitting machine comprising one or more needle beds according to the invention, at least one first needle is chosen, the longitudinal axis of which is contained in a plane perpendicular to the bed(s) of the machine, and the method comprises:
-
- a step consisting of transferring a mesh from the first needle to a first storage element situated below a first bed; and
- either a step consisting of transferring the mesh from the first storage element to the first needle,
- or a step consisting of transferring the mesh from the first storage element to a second needle,
- or a combination of two steps, the first step of the combination consisting of transferring the mesh from the first storage element to a second storage element situated below a second bed and the second step of the combination consisting of transferring the mesh from the second storage element either to the first needle, or to a second needle supported by a second bed, or to the first storage element.
According to the invention, the step consisting of transferring the mesh from the first needle to the first storage element may comprise a step consisting of transferring the mesh from the first needle to a first rocker at least partially overlapping the first needle and a step consisting of transferring the mesh from the first rocker to the first storage element.
According to the invention, the step consisting of making the transfer from the first rocker to the first storage element may comprise a step consisting of transferring the mesh from the first rocker to a second rocker at least partially overlapping a second needle and a step consisting of transferring the mesh from the second rocker to the first storage element.
According to the invention, the step consisting of transferring the mesh from the first storage element to the first needle may comprise a step consisting of transferring the mesh from the first storage element to a first rocker at least partially overlapping the first needle and a step consisting of transferring the mesh from the first rocker to the first needle.
According to the invention, the step consisting of transferring the mesh from the first storage element to a second needle may comprise a step consisting of transferring the mesh from the first storage element to a second rocker at least partially overlapping the second needle and a step consisting of transferring the mesh from the second rocker to the second needle.
According to the invention, the second step of the combination consisting of transferring the mesh from the second storage element to the first needle may comprise a step consisting of transferring the mesh from the second storage element to a first rocker at least partially overlapping the first needle and a step consisting of transferring the mesh from the first rocker to the first needle.
According to the invention, the second step of the combination consisting of transferring the mesh from the second storage element to the second needle may comprise a step consisting of transferring the mesh from the second storage element to a second rocker at least partially overlapping the second needle and a step consisting of transferring the mesh from the second rocker to the second needle.
A flat knitting machine comprising one or more needle beds according to the invention comprises a plurality of storage elements capable of storing at least one mesh, the storage elements being situated below the bed(s) of the machine and the storage elements being movable relative to the bed(s) of the machine such that each storage element can seek a mesh supported by a needle, bring a mesh toward a needle, look for a mesh supported by another storage element, and bring a mesh toward another storage element.
According to the invention, each storage element may be movable relative to the bed(s) of the machine, such that each storage element can look for a mesh supported by a rocker at least partially overlapping a needle and bring a mesh toward a rocker at least partially overlapping a needle.
Other features and advantages of the invention will emerge from reading the following description, in reference to the appended drawings, in which:
As shown, below the beds, and thus below the needles, a plurality of storage elements 5, 5′ are arranged. It will immediately be understood, upon reading
It will also be noted here that, in the rest of the description, when mention is made of crossing a storage element with a needle or with another storage element, that crossing is in fact possible owing to the fork-shaped structure of the front end 22 of the storage elements.
It should also be specified that all of the transfers defined by the various alternatives of the knitting method that will be presented below only occur between elements (needles, storage elements) whereof the longitudinal axes are coplanar and are in particular located in a same plane perpendicular to the bed, in the case of a flat knitting machine only comprising a single bed, or the beds, in the case of a flat knitting machine comprising more than one bed.
The mesh is initially stored on the needle 4 (
The mesh is initially stored by the storage element 5 kept below the bed (
The mesh is initially stored on the needle 4 (
The mesh is initially stored by the storage element 5 situated below the bed (
The mesh is initially stored by the storage element 5 situated below the bed (
The mesh is initially borne by the needle 4 supported by the front bed 2 (
The mesh is initially stored by the storage element 5′ situated below the rear bed 3 (
It should be noted at this stage that the mesh can also be transferred to the needle 4′ by reproducing the steps of the method described relative to
The mesh is initially stored on the storage element 5′ of the rear bed 3 (
The mesh is initially stored on the needle 4 supported by the front bed 2 (
The mesh is initially stored on the storage element 5′ kept below the rear bed 3 (
From this point, several scenarios are possible. The mesh can obviously be transferred to the needle 4. The mesh can also be transferred to another storage element. The mesh can also be transferred directly onto the needle 4′ or to another needle, in the case of a machine comprising more than two beds. The mesh can also be transferred on the rocker of the needle 4′ or to the rocker of another needle, in the case of compound needles. Lastly, the mesh can also remain stored on the rocker, which retracts slightly while keeping the mesh.
The mesh is initially stored on the storage element 5′ kept below the rear bed 3 (
The mesh is initially supported by the needle 4′ supported by the rear bed 3. This needle and the rocker 51′ then advance (
Various alternative embodiments of the knitting method have been presented, out of a concern for clarity, in the case of a flat knitting machine comprising one or two beds. As already stated, it is, however, clearly possible to implement this knitting method on machines comprising more than two beds, in particular on machines comprising three, four or five beds. Thus, other alternative embodiments are possible and the subject-matter of the protection is not limited to the alternative embodiments described above, but on the contrary encompasses all alternative embodiments that fall within the scope of the claims: in particular, one skilled in the art will understand that by providing one or several beds for the machine with storage elements situated below the beds, the mesh transfer is in those cases no longer done only between the front and rear beds, as described above, but may be done from one bed to the other, independently of their respective positions. For example, in the case of machines comprising more than two beds, all of the alternative embodiments of the method that have been presented primarily relative to a machine comprising two beds can be transposed to knitting machines comprising more than two beds. One skilled in the art will understand that, in all of the preceding description, the term “front bed” should be replaced by “first bed” and the term “rear bed” by “second bed,” and the technical portions necessary for the obvious transposition of the teaching relative to the flat knitting machines comprising two beds to flat knitting machines comprising more than two beds should be replicated symmetrically in the accompanying drawings.
According to another alternative embodiment of the knitting method according to the invention, applicable to machines comprising one or more beds, it is also possible, when the mesh is, at a certain stage of the knitting method, stored on a storage element, to move the device holding the storage elements, and thus the storage elements, in a translational movement in a direction parallel to the bed(s) of the knitting machine, which then makes it possible to subsequently transfer the mesh from the storage element thus moved to a needle which the longitudinal axis is contained in a plane parallel to the plane that contained the longitudinal axis of the storage element before that translational movement was done. The translational movement described above, also called “racking,” is well known by those skilled in the art.
