METHOD OF PREPARATION tubular products such as hosiery or the like, to the automatic taking off the end of his formation on the two-cylinder circular knitting machine with at least one zone feed or reset and double cylinder knitting machine for this method

摘要

A method of preparing a tubular article, such as a hosiery or the like, for automatically taking off at the end of its formation on a two-cylinder circular knitting machine with at least one feed or discharge zone and to a two-cylinder circular knitting machine for its execution. The considered method is carried out on a machine with at least one zone (100) of supply or discharge and with needle cylinders (4, 5) driven by rotational movement around their axes (3) relative to the cams to actuate needles, cams (34) to actuate the dumping plates (33) and the feed zone (100) or discharge. The method includes the first stage in which the transfer or retention of all the needles (8) in the lower needle cylinder (4), meshed with the last knitting stitches of the product (80) previously formed in the upper head (9a) of the needles (8), pulling the product (80) down into the bottom of the needle cylinder (4); the second stage in which pushing up part of the product (80) engaged with needles (8) is carried out; the third stage in which all the needles (8) are moved to the position of the pressed-in loop; the fourth stage in which gradual detachment of the ejecting plates (33) from the product (80) is carried out by moving the ejecting plates (33) from the axis (3) of the lower needle cylinder (4) in the zone (100) of supply or discharge, due to the rotation of the lower needle cylinder (4) around its axis (3) with respect to the feed or discharge zone (100) and the needles actuating cams so that the product (80), due to the upwardly directed thrust, moves so that the loops of its last knitting row (80a) lie above the spout ( 33b) dumping plates (33) in the direction of the upper head (9a a) needles (8); the fifth step in which all the needles (8) are moved to an intermediate position, which is between the position of the pressed-in loop and the position of the dropped loop; the sixth stage in which the pushing of the part of the article (80) engaged with the needles (8) is carried out further upwards; the seventh stage in which the needles (8) are lifted at least to the position of the dropped loop, continuing to push the product (80) upward to hold the loops of the last knitting row (80a) in the top head (9a) of the needles (8).
