  • Patent number: 4697440
    Abstract: A knitted garment, such as tights, is made using circular knitting machine for simultaneously making several pairs of the garment, with two tubular legs and a body portion having a front and a back. The machine comprises a movable unit carrying a cylinder with a circle of cylinder needles and a plate carrying an adjacent circle of plate needles. The movable unit moves with alternating rotary movement relative to several thread guides disposed around the circles of needles. In order to make several garments simultaneously, the circles are divided into as many arcuate groups of needles as there are garments. Each arcuate group is divided into two equal sub-groups separated by a middle group. The needles of each group are automatically brought into operation in a sequence to knit the toes and legs (on the subgroups), then the crotch (using the middle group as well), then the body (still using two threads, one for the left-hand and one for the linked right-hand side).
