摘要:
A method for preparing a tubular article, such as a sock or the like, for automated pickup at the end of its forming on a double cylinder circular machine with at least one feed or drop, and to a double cylinder circular machine for the execution thereof. The method in question is executed on a machine with at least one feed or drop and with the needle cylinders actuatable with a rotary motion about their own axes with respect to needle actuation cams, to cams for actuating the knockover sinkers and to the feed or drop.
摘要:
A double-cylinder circular hosiery knitting machine with device for tensioning the manufacture during its production, comprising a supporting structure (2) which is provided with a footing (3) and supports, so as to allow rotation about its own vertically oriented axis (4), a lower needle cylinder (5) and an upper needle cylinder (7), which can be positioned, during the production of the manufacture (12), above and coaxially with respect to the lower needle cylinder (5). The needle cylinders (5, 7) are actuatable with a rotary motion about their axes (4, 6) with respect to the supporting structure (2), and a device (1 1) for tensioning the manufacture (12) during its production is accommodated inside the needle cylinders (5, 7) and comprises means (13) for retaining the manufacture (12) proximate to the region where knitting is formed by the needles (10) accommodated in the needle cylinders (5, 7), and a tensioning tube (14), which is accommodated in the upper needle cylinder (7) and is movable on command along the axis (6) of the upper needle cylinder (7). The lower end of the tensioning tube (14) is engageable, by sliding along the axis (6) of the upper needle cylinder (7), with the region of the manufacture (12) being formed that lies from the retention means (13) to the needles (10). The retention means (13) have a size suitable to allow the movement of the tensioning tube (14) about the retention means (13), and means (15) for the translational motion of the tensioning tube (14) along the axis (6) of the upper needle cylinder (7) are provided. The retention means (13) comprise a suction tube (16), which is accommodated internally and coaxially to the lower needle cylinder (5), and an element (17) for locking the manufacture (12), which faces the upper end of the suction tube (16) and is supported by the upper needle cylinder (7). The locking element (17) is movable on command along the axis (6) of the upper needle cylinder (7) to engage or disengage the upper end of the suction tube (16).
摘要:
An automatic sewing device (1), particularly for hosiery knitting machines, characterized in that it comprises a supporting arm (2, 3, 4) for an oscillating means (7, 8 ), which comprises at least one first oscillating assembly (7), constituted by a semicircular ring, and at least one second oscillating assembly (8), constituted by a second semicircular ring, a means (11, 12 ) for actuating the oscillating assemblies which is suitable to produce at least one open position, in which the oscillating assemblies substantially form a ring which has the same size as the needle cylinder (24) from which it picks up a hosiery item at the end of the knitting process, and at least one closed position, in which the oscillating assemblies close the hosiery item in a semicircular arrangement, ready to be sewn, in a sewing station, the support being movable from at least one position for gripping the hosiery item from the needle cylinder to at least one position for applying the hosiery item to the sewing station.
