摘要:
A method for preparing a tubular manufacture such as a hosiery item or the like for automated pick-up at the end of its formation on a double-cylinder circular machine including at least the following steps: —a first step, which consists in transferring or retaining all the needles in the lower needle cylinder; —a second step, which consists in moving all the needles to the tuck-stitch position; —a third step, which consists in pushing upward the portion of the manufacture engaged with the needles; —a fourth step, which consists in disengaging the sinkers from the manufacture; —a fifth step, which consists in lifting the needles into the dropped-stitch position.

The dial needle selector mechanisms comprise selector rods (30) limited in both directions radially to the respective dial needles.
摘要:
A device for takedown of the article being formed, for circular knitting machines, comprising at least one takedown roller, which is supported, so that it can rotate about its own axis, by a supporting structure and can engage, by means of its lateral surface, the article to be taken down. There are reloading means, which operate on a motor element to cause its rotation about a main axis in a second direction of rotation that is opposite to the first direction of rotation. The reloading means comprise a fluid-operated reloading cylinder, which is supported by the supporting structure and operates with the stem of its piston on the motor element with a reloading force that is oriented along a direction spaced from the main axis for applying to the motor element a reloading torque that is oriented concordantly with the second direction of rotation.

A connection device (4) for piezoelectric actuators (3) of jacquard bars for textile machines, comprising a bearing body (32), a plurality of interconnection elements (34) inserted into the bearing body (32), which can be removably connected to a corresponding plurality of interface electric contacts (9) of a plurality of piezoelectric actuators (3), at least one interconnection terminal (33) for the interconnection elements (34) with control means of a textile machine, and at least one fastening portion (35) configured and arranged so as to removably mount the bearing body (32) onto a supporting body (7) of a jacquard thread-guide bar (2).
摘要:
A knitting machine with latch needles and without sinkers comprising, in regions of the needle holder comprised between two contiguous slots which accommodate a corresponding needle, a knitting retention element with a portion forming a stop shoulder for the knitting; the knitting retention element can move on command from a first position, of no interference with the knitting formed, to a second position, of it insertion with the portion between two contiguous needles in a region which faces the knitting forming plane, such as retain the knitting portion lying between two contiguous needles, contrasting the entrainment of the knitting along the needles during extraction motion of the needles from the needle holder to release, onto their shank, the previously formed loop of knitting and/or to engage the yarn delivered at a feed or drop of the machine.
摘要:
A method and an apparatus for closing a tubular knitted article at one of its axial ends, at the end of its production cycle on a circular knitting machine for hosiery or the like. The method consists in ending the production of an article at one of its axial ends. The article is then picked up from the machine and transferred to a handling device located in a sewing or looping station. The pick-up is performed by transferring individually the loops of the last row of knitting from the needles of the machine to spikes of the handling device, which has an annular body composed of two semiannular elements. The article is then turned, and one of the two semiannular elements is turned over with respect to the other one, so that the spikes of one semiannular element face, and are aligned with, the spikes of the other semiannular element. The loops of knitting arranged on the spikes of one semiannular element are transferred to the spikes of the other semiannular element so that each spike of the latter semiannular element supports a pair of loops of knitting.
摘要:
A method for producing textile articles with warp-knitting machines, comprising a plurality of steps of shifting at least a first thread-guide (3) bar (2) of jacquard type with shog translational movements and with swing transversal movements, so as to produce textile articles on at least one needle bed (52), shifting at least the first thread-guide (3) bar (2) by means of a corresponding first linear motor, with a shog movement of a first predefined width; varying automatically through control devices (60) the shift controlled by the first linear motor so as to vary the width of the shog movement during the production of the textile articles, and shifting at least the first thread-guide (3) bar (2) with a shog movement having a second predefined width differing from the first one, and automatically controlling by means of the control devices (60) connected to the first thread guide (3) bar (2) at least an individual shift of a needle space of at least a first thread-guide (3) of the first bar (2), in addition to or in deduction from and during at least one of said shog movements.
摘要:
A device for feeding yarns for knitting machines comprising a supporting element arranged on the inner side of the machine bed which supports a set of yarn guides arranged side-by-side. Each of the yarn guides has a passage for at least one yarn to be fed to the needles of the machine arranged in the bed and the supporting element, for each of the yarn guides, supports an element for clamping and cutting the yarn dispensed by the corresponding yarn guide. A first actuator for the yarn guides is provided for the passage of the yarn guides from an inactive position to an active position, and a second actuator is provided for actuating the clamping and cutting elements. The first actuator comprises individual actuators actuated to produce passage of each of the yarn guides from the inactive position to the active position or vice versa.
摘要:
A method for manufacturing knitted articles for forming items of clothing, without lateral seams, with a circular knitting machine, comprising a step for forming at least one pouch-like region, in which part of the needles or all the needles that belong to at least one sector of the needle cylinder are moved to knit at at least one feed of the machine by way of an alternating rotary motion of the needle cylinder about its axis and with an oscillation extent sufficient to produce transit, at the feed, of all the needles of the sector that are moved to knit at the feed, in order to form, with the needles that belong to the sector and are moved to knit, a number of rows of knitting in excess with respect to the number of rows of knitting formed by the needles contiguous to the sector.
摘要:
An oscillating control device (1) for thread-guide bars (2) of linear knitting machines (60), comprising a support (5) that can rotate around a middle axis (6) to which at least one thread-guide bar (2) can be associated, movement means (10) for the support (5), and transmission means (20) operatively connected to the movement means (10) for imparting an oscillating movement to the support (5). The transmission means (20) are operatively associated to the support (5) on at least two separate actuating points (7a, 7b) for moving it with an oscillating movement in a balanced manner with respect to the middle axis (6) thereof. In particular, a pushing action and a pulling action are applied simultaneously on the two actuating points (7a, 7b) by the movement means (10) through the transmission means (20).
