DOUBLE-CYLINDER CIRCULAR HOSIERY KNITTING MACHINE WITH DEVICE FOR TENSIONING THE MANUFACTURE

摘要

The present invention comprises a support structure (2) provided with a footing (3), the support structure (2) being arranged to allow the lower needle cylinder (5) to rotate about its own axis Which supports the lower needle cylinder 5 and which supports the upper needle cylinder 7 which can be coaxially positioned on the lower needle cylinder 5 during the production of the product 12, To a double cylinder circular sockliner having a device for tensioning the product at the time of production. The needle cylinders 5 and 7 can be operated to rotate about their own axes 4 and 6 with respect to the support structure 2 and the device 11 for tensioning the product 12 at the time of production Wherein the device is housed in the needle cylinder and wherein the device comprises a needle cylinder which is received within the needle cylinder and which is adjacent to an area of the product to be knitted by the needle, And a tension tube (14) received in the upper needle cylinder (7) and movable along the axis (6) of the upper needle cylinder (7) according to an instruction do. The lower end of the tensioning tube 14 is displaced from the retaining means 13 to the needle 10 due to the sliding movement of the upper needle cylinder 7 along the axis 6, 12). / RTI The holding means 13 is of a size suitable for enabling the movement of the tension tube 14 relative to the holding means 13 and is arranged along the axis 6 of the upper needle cylinder 7, Means 15 for translational movement of the tension tube 14 are provided. The holding means 13 comprises a suction tube 16 coaxially received in the lower needle cylinder 5 and a product 18 supported by the upper needle cylinder 7 facing the upper end of the suction tube 16 And a locking member 17 for locking the locking member 12. The locking member 17 may be moved along the axis 6 of the upper needle cylinder 7 in accordance with a command to engage or disengage with the upper end of the suction tube 16. [
