摘要:
A sewing or looping head, particularly for the automated closing of tubular knitted articles at one of their axial ends comprising a pair of sewing elements, which can move along corresponding actuation paths and cooperate with each other in forming a sewing chain stitch, and a cutting element, which can be actuated to cut the sewing chain stitch; in the sewing or looping head, the cutting element can engage the sewing chain stitch proximate to the crossing point of the paths of the pair of sewing elements or the point where the sewing chain stitch is formed, so as to minimize the length of the sewing chain stitch that exceeds the length needed to sew or loop the article and so as to reduce the time required to perform the sewing or looping operation.

A sinkerless knitting machine with latch needles, comprising a needle holder with a plurality of slots on one face, each slot accommodating a needle. Knitting retainers are provided, each with a body composed of at least two side-by-side interconnected laminar elements. At least two laminar elements of each knitting retainer are arranged in a same or in two contiguous slots of the needle holder. At least one of the laminar elements composing a knitting retainer has a retention portion defining a stop shoulder for the knitting. Each knitting retainer can move on command from a first position, in which it does not interfere with the knitting being formed, to a second position, in which it is inserted, with the retention portion, between two contiguous needles, in a region which faces the knitting forming plane, in order to retain the portion of knitting that lies between two contiguous needles.

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 circular knitting machine for hosiery or the like, which comprises at least one needle cylinder which has a vertical axis and on the lateral surface of which there are axial slots. Each of these axial slots accommodates a needle (106) and an actuation element (110) for the needle (106) which can engage, with one of its ends, the needle (106) arranged in the same axial slot. The needle (106) or the actuation element (110) is provided with a fixed heel (103a), which protrudes radially from the axial slot, and a movable heel (104a) which can be extracted radially on command from the axial slot. Actuation cams are arranged around the needle cylinder and can be engaged by the fixed heels (103a) and by the movable heels (104a) in the extracted position. The machine can perform the usual knitting of known types of machine despite having an actuation cam set which has an extremely small number of actuation cams which can move for activation or deactivation, or none at all.

A circular knitting machine for hosiery or the like, comprises at least one needle cylinder with vertical axis and has, on its lateral surface, a plurality of axial slots, each of which accommodates a needle and an element for actuating the needle. The actuation element comprises at least one connecting element and a selector. The connecting element is provided with a radially actuatable movable heel, and the selector protrudes with a portion between the bottom of the axial slot and the connecting element in any operative position of the machine. The selector is oscillatable on a radial plane of the needle cylinder to produce oscillation of the connecting element and extract its movable heel from the axial slot to achieve engagement with connecting element actuation cams facing the lateral surface of the needle cylinder.
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:
A circular knitting machine, comprising a footing with a vertically rotatable needle cylinder with a diameter comprised between 7 and 24 inches, and multiple axial needle accommodation slots; an actuation for actuating the needles, during rotation of the needle cylinder to form knitting with at least one yarn dispensed to the needles at least one drop or feed of the machine. The needle cylinder is rotatable about the axis in both directions of rotation and the needle actuator allows the needles to form knitting in both directions of rotation of the needle cylinder at least one drop or feed of the machine.
摘要:
A method for producing intarsia designs with a circular knitting machine, comprising correlating needle sets for producing regions of design in different colors threads, with respective feeds of the machine, moving for knitting the needles of each needle set at the corresponding feed by alternating rotary actuation of the needle cylinder, with an oscillation sufficient to produce transit of the needles of each set of needles at the corresponding feed, forming knitting both in forward and return rotations of the needle cylinder, and moving needles located at ends of each needle set to knit both at the feed correlated with its needle set and with the contiguous needle set.
摘要:
A sinker selection device in a circular knitting machine, comprising for each radial slot of the sinker ring in which sinkers are accommodated, a selector facing the end of the corresponding radial slot directed away from the axis of the sinker ring, the selector being oscillatable on a radial plane with respect to the sinker ring to pass from active to inactive positions, and connected to the corresponding sinker, arranged in the corresponding radial slot, to induce different actuation of the corresponding sinker along the corresponding radial slot, depending on whether the selector is in the inactive position or in the active position. A selection actuator is provided which laterally faces the sinker ring and can engage on command the selector for transfer from inactive to active positions.
