Definitions
- the present invention relates to an improvement made to the trades circular knitted stitches for loop type knitwear Jacquard.
- Such articles have been known for a very long time and can be used either such as, either in order to achieve a velvet obtained by shaving the loops formed when knitting.
- Jacquard knitwear of this type on multi-fall circular looms comprising a cylinder fitted with pallet needles and a plate provided with plates, displaceable between the needles of the cylinder and making it possible to form the loops, loops which can be of different heights as shown in particular from US patents 1,790,832, 3,477,255 and 3,394,564.
- these plates have, arranged in the same vertical plane, three areas arranged at different levels from the plane horizontal knitting, and set back from each other at the front of each deck.
- the extreme zone constitutes the zone of knitting of the meshes after formation, the knitting yarn constituting the jersey base of the knitted fabric being distributed at this level.
- each plate has a “nose” with two levels arranged in withdrawal from each other.
- the plates are moved by means of a selection block which penetrates two predetermined values between the needles so that the wire which forms the loop, wire which in the following description will be designated by the expression "colored thread”, either deposited around one or the other of the two overlapping areas of the nose.
- Jacquard knitwear presenting, according to a predetermined pattern, a combination of knitted areas without loops and areas comprising two different loop heights, loops which can later receive a finishing treatment to give the item looks like velvet.
- Such articles therefore comprise, in each knitting row, on the one hand a ground wire and, on the other hand, a colored wire forming loops of heights different.
- the invention therefore relates to a new type of circular knitting loom, picked type, of a cylinder type equipped with pallet needles and a tray provided with plates movable between the needles of the cylinder, allowing a knitting in which each row includes, in addition to a jersey or structured bottom thread, one or more colored threads distributed successively to the needles of the loom according to the selection of a drawing to be made, the distribution of the colored thread (s) being carried out by through the turntables also associated with a selection system allowing the formation, also according to a predetermined pattern, of loops having two different lengths.
- each plate is consisting of three elementary plates, arranged side by side, the central plate being a conventional felling plate on either side of which are arranged two loops forming plates each having a nose, the two noses being arranged at two different levels, said elementary plates being actuable independently of one another, according to a selection predetermined function of the drawing between a position out of work and a position in work of taking the colored thread thus making it possible to produce, according to a drawing, loops having two different heights.
- the colored wires are distributed to the plates always in the same vertical plane, which eliminates all risks of variation of tension during knitting likely to cause defects in the finished product.
- the profession is therefore adapted and has three cam tracks, to ensure the movement of the plates elementary during the knitting cycle.
- a conventional selection block ensures the order, in depending on the design to be produced, i.e. the plate allowing the formation of a loop high, that is the plate allowing the formation of a low loop.
- the basic knitting can be a jersey knitting, it can possibly be considered to ensure the order of the plates of the background knitting via a second selector thus obtaining a background structure.
- the loom in accordance with the invention therefore conventionally comprises a cylinder (1) equipped with pallet needles (2) and a so-called “ring” plate (3) equipped plates, designated by the general reference (4) movable between the needles of the cylinder.
- each row comprises, in addition to a jersey or structured bottom thread, one or several colored threads (6) distributed successively to the needles (2) of the loom depending on the selection of a drawing to be made.
- each plate (4) consists of three elementary plates (7,8,9), arranged side by side and actuable independently of each other instead of a single plate with a zone slaughter and two overlapping noses to obtain two heights of loops different.
- These elementary plates are made of all appropriate materials, steel for example and are in the form of a thin plate in general of the order of 0.2 mm.
- the plate (7) called “bottom plate” is a conventional plate. Departure and on the other side of this central plate (7), are arranged two plates (8, 9) of forming loops, each of these plates (8,9) having a nose (10,11) arranged at two different levels above the bottom plate (7).
- the plates (7,8,9) can be actuated independently of each other, the ring or plate (3) of the loom therefore comprising three cam paths, one (20) ensuring the movement of the bottom plates, the other two (21,22) allowing, for their part, to ensure the movements of the plates (8) and (9) forming high or low curls.
- the movement of the plates is controlled so that conventional by means of pushers (23) actuated by means of a selection block (24) shown diagrammatically in FIG. 1 and the means of holding on the plate fitted with plates is not shown.
- each knitting row therefore comprising, in addition to a Jersey or structured bottom thread, a or more colored threads.
- Figures 2,3 and 4 illustrate how loops are made on a such a trade.
- the two plates (8, 9) are brought into position for gripping the wire (6) which therefore surrounds the nose (11) of the plate (8), thus allowing the formation of high loops.
- the plate (8) When you want to create areas with low loops (see Figure 3), the plate (8) is brought into the out of work position and the wire (6) is distributed around the nose (11) of the plate (9), thus allowing the formation of a loop low.
- the invention as said previously can be used not only to make Jacquard knits in which each row has a ground wire and several colored wires in accordance with the teachings of EP-A-629 721, but it could be envisaged to equip Jacquard looms conventional for making articles with loops different heights, such as those described in US Patents 1,790,832, 3,477,255 or 3,394,564 mentioned in the preamble to the description, the pile being obtained by shaving said loops.

Description
- la figure 1 est une vue schématique, en élévation, montrant la structure des principaux organes d'un métier réalisé conformément à l'invention ;
- la figure 2 illustre la formation d'une boucle haute sur un tel métier, la figure 3 la formation d'une boucle basse et la figure 4 la phase de relâchement des boucles après formation de la maille ;
- la figure 5 est quant à elle une vue de dessus montrant le positionnement des trois platines élémentaires constituant la platine proprement dite de formation de mailles.
Claims (2)
- Métier à tricoter circulaire à mailles cueillies permettant de réaliser des tricots velours et/ou bouclettes de type Jacquard du type comportant un cylindre (1) équipé d'aiguilles à palettes et un plateau (3) muni de platines (4) commandées par un système de sélection permettant la formation, selon un dessin prédéterminé, de bouclettes ayant deux longueurs différentes, caractérisé en ce que chaque platine (4) est constituée de trois platines élémentaires (7,8,9), disposées côte à côte, la platine centrale (7) étant une platine conventionnelle d'abattage de part et d'autre de laquelle sont disposées deux platines (8,9) de formation de boucles comportant chacune un nez (10,11), les deux nez étant disposés à deux niveaux différents, lesdites platines élémentaires (7,8,9) étant actionnables indépendamment l'une de l'autre, selon une sélection prédéterminée fonction du dessin, entre une position hors travail et une position en travail de prise du fil dit de couleur qui forme la boucle, permettant ainsi de réaliser selon un dessin des boucles ayant deux hauteurs différentes.
