Abstract: A double-cylinder circular machine for producing tubular knitted manufactures, particularly for making hosiery items or the like, which comprises a supporting structure which is provided with a footing for resting on the ground which supports, so that it can rotate about its own vertically-oriented axis, a lower needle cylinder. The supporting structure comprises at least one column which is extended substantially vertically, protrudes upward from the footing and supports, so that it can rotate about its own axis, an upper needle cylinder, the upper needle cylinder is supported, so that it can rotate about its own axis, by an arm, which in turn is supported by the column, elements being provided for the rotation of the arm about the axis of the main shaft with respect to the column to provide the transition of the upper needle cylinder from an active position to an inactive position.

Abstract: A knitting method for knitting, by a double knit electric jacquard circular knitting machine with needle selection on dial and cylinder, a knitted fabric in which a pattern on a front face of the knitted fabric is knitted by using one of a cylinder and a dial, boundaries between motifs of the pattern in a wale direction being continuous at the same position in the wale direction in a plurality of successive courses, and a pattern on a back face of the knitted fabric is knitted by using the other of the cylinder and the dial. The knitted fabric is knitted such that knit structures adjacent, on the back face of the knitted fabric, to a border line in the wale direction that is formed by the boundary between the motifs on the front face of the knitted fabric in at least one course of the number of successive courses that is fewer by one than the number of types of jacquard knitting yarns used are successively knitted.

Abstract: A double-cylinder circular machine, particularly for knitting hosiery items, with simplified actuation mechanism, comprising a supporting structure which comprises a footing, which supports a lower needle cylinder, and a column which extends substantially vertically, protrudes upwardly from the footing and supports an upper needle cylinder, which is arranged above and coaxially with respect to the lower needle cylinder, and further comprising elements for the actuation of the lower needle cylinder and of the upper needle cylinder with a rotary motion about a common axis, the actuation elements comprising an electric motor which is connected kinematically to the lower needle cylinder and to the upper needle cylinder and is accommodated inside the column.

Abstract: The method comprises the phases of: knitting at least one part (5 A, 5B) of the body (1) with reciprocating motion of the two cylinders of a double-cylinder machine; —knitting the leg pieces (9A, 9B) with a continuous rotational motion of the two cylinders (11, 13), a first leg piece being knitted by a first of said cylinders and a second leg piece being knitted by a second of said cylinders. It is provided for an arc of needles (C) to be maintained temporarily inactive on each of said two cylinders while knitting said at least one part (5 A, 5B) of the body (1) with reciprocating motion. Furthermore, it is provided that the temporarily inactive needles are set to work at the end of the knitting of said at least one part (5 A, 5B) of the body (1) with reciprocating motion, thus forming an interknitting line (CC) for joining the two leg pieces (9A, 9B), then continuing the knitting with continuous rotary motion with all the needles (15) of both the cylinders (11, 13).

Abstract: The invention is a new container for food and for cooking food, entirely or partially made from a plastic film, provided with one opening (B) suited to be closed and hermetically sealed after the introduction of the food to be cooked and comprising at least one valve (L) made from a material having a lower melting point than said plastic film, so that the increase in temperature and pressure inside the container during the cooking of the food causes said valve (L) to open and part of the steam generated inside the container to be discharged.

Abstract: A slider for double-cylinder circular knitting machines which comprises an elongated laminar body which has a first longitudinal side which is meant to be rested on the bottom of an axial slot formed in the curved surface of the lower needle cylinder or in the curved surface of the upper needle cylinder and at least two heels which protrude transversely to the longitudinal extension of the laminar body on the second longitudinal side of the laminar body that lies opposite the first side. The laminar body has, proximate to one of its longitudinal ends, a hook for engagement with a needle. A first one of the two heels is arranged on a portion of the laminar body which can move with respect to the remaining part of the laminar body in a direction which has a component which is transverse with respect to the longitudinal extension of the laminar body for the transfer of the first heel from an inactive position to an active position, or viceversa.

Abstract: The invention relates to a yarn guide unit particularly for circular double cylinder hosiery machines in which a yarn guide rod is borne on a block (16) eccentrically pivoted on a rotating disk (18) which can move between two extreme angular positions corresponding to the engaged working and disengaged positions of the yarn guides. Rotation of the disk with the block is brought about in one direction by a pneumatic actuator (28) incorporated in the block (16) and in the opposite direction by a return spring attached to the disk.

Abstract: A sock or other tubular article with one closed end and with rib fabric--that is, with face and reverse stitches--is formed in a double-cylinder circular machine (1, 3), in which the toe is closed at the end of the process of forming the tubular fabric, by a device (41, 51, 53, 49) that transfers the stitches of one semicircle to the stitches of the opposite semicircle.

Abstract: A knitting machine is provided for producing tubular articles based on two fixed bars of needles wherein rows are formed partly by the needles of one bar and partly by the needles of the other bar. A thread is provided which is displaced alternately in both directions along the bars. Cam rings are provided rotating in continuous motion and in opposite directions. Each of the cam rings including cams acting on one of the needle bars for providing trajectories of the needles of one of the two bars forming a limited angle, generally than 30.degree., relative to the trajectories of the corresponding needles of the other bar. The needles of the two bars are arranged offset and are controlled by the cams to provide the sliding movement necessary for the formation of the stitches of the tubular fabrics. Sliding movement is provided such that the hooks do not cross over during the formation of stitches such that it is possible to work on both bars simultaneously.
