Definitions

  • the present invention relates to a device for forming knitted pockets with a circular machine for tubular manufactured products with continuous unidirectional movement and a circular machine thus equipped.
  • a method for forming a mesh pocket in a tubular manufactured product with a circular hosiery machine with continuous rotary movement which consists in providing an additional yarn for the partial rows of stitches which is continuous and is supplied by a yarn guide.
  • additional rotating around the needle cylinder with varied movement, stopping, at each turn, in correspondence of a first position of stitch formation to supply the needles with an arc of needles which pass in front of it, therefore exceeding said needles until correspondence of a second stitch formation position and from here continuing with constant speed, but greater than that of the needle cylinder and finally, after a complete revolution, stopping in the initial position.
  • EP-A-0114153 (representing the state of the art according to article 54 (3) EPC) from the same co-owner there is also known a device for feeding the wire from the additional wire guide intended for training of the second partial row of stitches according to the aforementioned method, which device makes it possible to accumulate a quantity of yarn to the correct extent required for the formation of the second partial row of stitches, without tension.
  • This known machine also includes a thread guide rotating at the head and in harmony with the needle cylinder and in phase with said drop so that, each turn, this thread guide stops behind the drop, then it accelerates to exceed the fall, then it rotates with the same speed as the fall and finally it decelerates until it stops in the initial position; several needles for the formation of partial rows of stitches distributed according to one or more partial arcs of the needle cylinder; means for carrying in rotation with varied movement the drop and the thread guide; and means for bringing the position of the thread guide into phase with the position of the fall during their respective rotation.
  • the main purpose of the present invention is to provide a different machine for carrying out the above process, very simple and efficient, so as to obtain a circular machine of great reliability and versatility and low cost.
  • the advantages obtained thanks to the present invention essentially consist in the fact that various manufactured products are obtained with pockets of various shapes, sizes and positions, with continuous wire and with unidirectional movement of the circular machine; that among the manufactured products achievable there are stockings and socks with heel and pocket stitch, panties with bellows and stockings with semi-bellows for pantyhose with bellows; that pockets can be obtained with several yarns of different nature, fineness and color; that it is possible to use circular machines, single or double needle cylinder, with many feeds for the formation of the tubular and with two or multiple of two additional feeds for the formation of mesh pockets; it is possible to select needles to obtain pockets with patterned fabric; that it is possible to operate with great reliability and safety even at a much higher speed than that obtained today with circular machines with reciprocating motion; that a production far superior to that of said alternative machines is obtained; that the product obtained is of very good quality; that the relative simplicity of construction makes it possible to equip a circular machine for hosiery at a very studied and competitive cost.
  • fig. 1 shows the plan view of a fall according to the invention, excluding work;
  • fig. 2 represents the fall of FIG. 1 in the work phase during training in stoppage of the first partial row of stitches;
  • fig. 3 represents the fall of FIG. 1 in working phase during the movement training of the second partial row of meshes;
  • table 2 fig. 4 shows the sections at different speed of one turn of the chute and of the additional wire guide with, in the center, the cam for obtaining the relative speeds;
  • table 3 fig. 5 shows an axial vertical section of a circular hosiery machine equipped with a device according to the invention;
  • fig. 6 shows the plan view of the detail of a device for phasing the additional wire guide associated with the drop according to the invention; in table 4 fig.
  • FIG. 7 shows the plan view of a device for controlling the rotation of the chute and of the additional wire guide according to the invention
  • table 5 fig. 8 shows the developed section of a part of the device of FIG. 7
  • table 6 fig. 9 shows the developed section of the remaining part of the device of FIG. 7.
  • Said additional wire guide (98) is also notoriously displaceable radially to the cylinder (1) so that its mouth results, in the working phase. projecting outwards from the head of the needles and. out of work, it results in proximity to said neck (100).
  • one or more similar thread guides can be associated, positioned, superimposed or approached, to allow feeding with several pieces.
  • the needles (3) belonging to different partial arcs that is to say intended to form separate knitted pockets of the same manufactured product, have the upper heel of different length to be selected by the fall (200) beforehand positioned at corresponding distances from the cylinder (1).
  • the movement is transmitted by said shaft (237) to the shaft (97) of the additional thread guide (98) by means of an epicyclic train with coincident axes, with the main wheels (239-241) on the axle (237), the satellite wheels (240-242) on the axle (243), the train carrier (245), the wheel (241 ') and a toothed belt (246).
  • the train carrier (226) of the first planetary gear can move in both directions, with respect to a central position for which the gear transmission ratio is that defined by the number of teeth of the wheels (equal to one) while '' it is positive or negative with the movement of the train carrier in one direction or the other: so the instantaneous position of the train carrier (226) controlled by the position of the caster (227) on the cam (228) determines the instantaneous speed of the fall (200) and of the additional thread guide (98).
  • the train carrier (245) of the second planetary gear train which has two possible working positions defined by the contact of a caster with a cam fixed on the shaft (237) and not shown for simplification, determines the instantaneous position of the additional wire guide (behind or in front) compared to the chute (200).
