Abstract:
1. A method for producing automatically shaped tubular knitwear items ( 1 ) in circular knitting machines, said machines having at least a needle-bed, said method comprising: producing a first length of tubular knitted fabric having a cylindrical shape and ending with a last knitted course; excluding from the knitting process a predetermined number of needles (A); choosing said number of needles according to a predetermined sequence from at least a first portion of said needle-bed, said number of needles corresponding to a first portion of knitted tube; producing a second length of tubular fabric to include at least a first portion of knitted tube to have a differentiated growth of knitted courses and loops with exceeding stitches or inner frills (Bi); producing a second portion of knitted tube; corresponding said second length of tubular knitted fabric during said production to said first portion of said needle bed; obtaining a programmed three-dimensional deformation of knitted tube; reintroducing, after a predetermined time interval, said predetermined number of needles (A) of the needle-bed in the knitting process and producing a third length of tubular knitted fabric; continuously moving the needle cylinder during production of said length of tubular items; shaping and modeling said tubular items without standard cutting and sewing operations and without using elastic yarns; excluding inputs or commands normally directed to the needles during said production of said tubular items; maintaining said production in accordance with a jacquard design and/or work cycle of said knitting machine.
