Abstract: The device comprises a plate placed over the needle beds and provided with two vertical grooves for each work zone. Within the grooves small bars slide vertically because of the action of a rocking lever that acts on the bars through two arms. The rocking lever has a third arm subject to the action of a rack, while a segment is hinged to each small bar and bears, fixed to its lower end, a small rod having a "L" shape, for pressing over the fabric. The rod extends for the whole length of the associated work zone. The grooves determine the contemporary oscillation of the small bars in opposite directions during their vertical movement, to allow the concurrent change of position of the small rods, while a wedge-shaped element, for retaining the fabric, is placed at the beginning and at the end of each work zone.

Abstract: The device is fitted to a flat knitting machine comprising a carriage moving in a horizontal plane above two needle beds and comprises a casing, fixed to the carriage and supporting a vertical rod, able to slide, to which two cores, lower and upper respectively, in a ferromagnetic material are fixed, while a spring acts on the rod with an upward force; a first coil acts on the lower core in such a way as to exert an upward force on the same lower core and a second coil acts on the upper core in such a way as to exert a downward force on the same upper core.A vertical anchor plate is fixed to the lower core and is able, depending on the position of the rod, to strike ledges of a slide mounted so that it couples with, and is able to slide along, a bar located above the needle beds.

Abstract: The device is fitted to a flat knitting machine that comprises a carriage moving in a horizontal plane above two needle beds and featuring anchor plates that are able to move in a vertical plane.The device comprises a series of slides coupled with a bar, located above the needle beds, and provided with thread guides, each slide featuring a track in which two facing ledges are formed that can be struck by one of the anchor plates, consequently causing the slide to be drawn along. Two rockers pivot upon the slide, each of the these comprising two arms first and second, which respectively work in conjunction with a related ledge and a related side of the slide.If the second arm is kept alongside the side, the anchor plate is prevented from striking against the ledge whilst when the same second arm is moved away from the side the anchor plate strikes against the ledge.

Abstract: The device comprises drums, which are coaxial and supported by an axle, located below needle beds subjected to a constant torque acting with springs being provided inside the drums as a mechanical connection between them and the axle.Two pressure rollers for each drum are fitted to a number of arms mounted on a bar and holded in contact with the related drum, while electromagnets are provided to rotate one of the rollers by a predetermined amount in order to cause the related drum to be rotated in in synchrony with the formation of a corresponding portion of the last row of the fabric, that runs between the row of drums and related pairs of pressure rollers.

Abstract: The device comprises a box-shaped element, mounted to a carriage of a flat knitting machine, a plate located above the needle bed of the machine being an integral part of this element.The plate features vertical grooves on one of its sides, within which pins are housed so that they are able to slide along their axes, subject to the action of rockers, which are hinged to the plate and operated by a rod with rack section, located above the plate and moved along their axes in order to raise or respectively lower pins, to the lower ends of which stitch retaining-pressing means are fitted.

Abstract: An automatic flat knitting machine needle beds feature equidistantly spaced slots, perpendicular to the direction of travel of a carriage, inside each of which is inserted a needle and a sinker for selecting the latter, the needle featuring a butt that is mounted on it by means of a spring extension bent towards the inside of its related slot, so that the butt of the non-selected needle is not struck by the operational cams of the carriage, whereas the butt of the selected needle is struck by the operational cams of the carriage, due to the fact that the extension is bent towards the outside of the slot as a result of its having been struck by the upper head of the selection sinker.

Abstract: A device consists of equidistant rods, located below the needle bed of a machine, perpendicular to the traverse direction of movement of a carriage, with the upper ends bent downwards to form a corresponding number of latch sections, and directed towards the upper heads of the needle beds.The rods are controlled by a cam on the carriage; raising of the rods causes the latch sections to be inserted between the stitches of the fabric in the last rows of the fabric portion situated below the working area of the sections: in this way the latch sections act as stops for the rows.Downstream from the working area of the needles, there is a fabric presser plate which presses the row just formed in a downwards direction and according to a preset pressure.

Abstract: A device is designed to operate two slides to which corresponding stitch regulation cams are bound, and it includes: a plate, mounted on the carriage and located below the slides, that is able to be moved by means in relation to the carriage in the direction in which this latter is itself moved, two tracks, symmetrical in relation to a vertical plane, formed in the upper part of the plate, each constituted by flat horizontal surface and by a flat surface that follows on and inwards from the former, turning downwards, elastic means which keep the extremities of the slides in contact with the corresponding tracks.Movement of the plate in one direction causes the slide which is downstream in respect of the direction of movement to be lowered in proportion to the amount by which the former is moved.

Abstract: A device made in a carriage of an automatic flat knitting machine, consists of a plurality of identical consecutive units 100, each of which is located between a plane of symmetry of two groups of movable cams and a plane of symmetry of two first fixed cams designed to select sinkers arranged in the bottom middle section of as many slots made in a needle beds; in each slot there is a needle above the sinker.Each unit is made up of fixed and movable cams which operate in combination with the groups of cams and the first fixed cams to make plain stitches, and carryover stitches and to transfer and receive a stitch to and from another needle bed.It is also possible to control the density of the fabric and carry out the "three-way technique" using a first row of needles which make the plain stitch, a second row of needles which make the carryover stitch and a third row of needles kept in rest position.

Abstract: A device for controlling the tension of the knitted fabric includes two parallel rows of rollers, which are supported by two plane surfaces mounting two needle beds upon which a carriage is able to move longitudinally and alternately.The rows of rollers are located beneath the needle beds with the rollers of the first row, able to turn in a single direction, being in contact with the corresponding rollers of the second row, thus creating a series of independent pairs of rollers between which the knitted fabric is inserted.Each pair of rollers is moved by a rod, mounted on the second plane surface, featuring a heel upon which moving cams act determining the consequent rotation of the corresponding pair of rollers, while fixed cams, acting upon the heels, return the rods to their initial position.

Abstract: Inserted is each slit of the needle bed of this machine is a needle underneath which is placed a blade element that is provided with three butts, namely a first butt at the top, a second butt below, and a third butt at the bottom. The said third and last butt is carried by a tailpiece able to oscillate or undergo flexure, in contrast with elastic means, inside the corresponding slit.The selection of a blade element is defined by the operation of a selector element, integral with the carriage, whereby the first butt is intercepted causing the blade element to be raised from the neutral position.Through action exerted on the third butt by an operating cam, the blade element is raised further in cases when the selection operation is fully satisfactory; should this not be the case, as also when the blade element is in the neutral position, the cam acts as a guide for the said third butt in order to reach, or maintain, the said neutral position.

Abstract: The device comprises an electromagnet to the movable armature of which is integral a metal strap that supports, cantilever fashion, a shank provided with a plate. One part of the edge of the said plate is inserted in a slit machined in one extremity of a rod subjected to elastic means, guided in a way in which it slides, by a plate. The other extremity of the rod carries means for selecting a metal strap.With the electromagnet de-energized, the selection means do not intercept a butt provided on the metal strap but with the electromagnet excited, the selection means intercept the said butt and this cause the said strap to be raised and subsequently sent into operation.
