Abstract
A method for reversing a tubular knitted article (S) is disclosed. According to the method, the tubular knitted article (S), engaged at a first end thereof by a pick-up device (5) and hanging with a second end thereof from the pick-up device, is introduced in a reversing tube (15). The reversing tube (15) is moved through the pick-up device (5) so as to project with the upper end (15B) thereof above the pick-up device; and the reversing tube (15) is moved reciprocatingly up and down between an upper position and a lower position, while co-acting with a top clamping device (31) and a bottom clamping device (35) until the tubular knitted article (S) is entirely everted on the outer surface of the reversing tube (15).
Claims17
A method for reversing a tubular knitted article, wherein:
- the tubular knitted article, engaged at a first end thereof by a pick-up device and hanging with a second end thereof from the pick-up device, is introduced in a reversing tube, the reversing tube comprising a lower end, an upper end and a side wall extending from the lower end to the upper end;
- the reversing tube is moved through the pick-up device so as to project with the upper end thereof above the pick-up device;
- and
- the reversing tube is moved reciprocatingly up and down between an upper position and a lower position, while co-acting with a top clamping device and a bottom clamping device until the tubular knitted article is entirely everted on the outer surface of the reversing tube.
A device for reversing a tubular knitted article, comprising:
- a pick-up device adapted to engage a first end of the tubular knitted article;
- a reversing tube having an upper end, a lower end and a side wall extending from the upper end to the lower end, wherein the reversing tube and the pick-up device are adapted to be arranged in an approximately co-axial position, and wherein the reversing tube is adapted to move upwards through the pick-up device, from a position in which the upper end of the reversing tube is located under the pick-up device, to a position, in which the upper end of the reversing tube is located in a first vertical position above the pick-up device;
- a top clamping device adapted to pinch the tubular knitted article against the upper end of the reversing tube in the upper vertical position above the pick-up device and to move together with the reversing tube between the upper vertical position towards a second, lower vertical position, said lower vertical position being above the pick-up device;
- and
- a bottom clamping device arranged between the first upper position and the pick-up device and adapted to move selectively between a pinching position, adapted to pinch the tubular knitted article against the side wall of the reversing tube, and a position clear of the reversing tube.
A unit comprising:
- a circular knitting machine having a needle cylinder;
- and a device for reversing a tubular knitted article;
- wherein the device for reversing the tubular knitted article comprises:
- a pick-up device adapted to engage a first end of the tubular knitted article;
- a reversing tube having an upper end, a lower end and a side wall extending from the upper end to the lower end, wherein the reversing tube and the pick-up device are adapted to be arranged in an approximately co-axial position, and wherein the reversing tube is adapted to move upwards through the pick-up device, from a position in which the upper end of the reversing tube is located under the pick-up device, to a position, in which the upper end of the reversing tube is located in a first vertical position above the pick-up device;
- a top clamping device adapted to pinch the tubular knitted article against the upper end of the reversing tube in the upper vertical position above the pick-up device and to move together with the reversing tube between the upper vertical position towards a second, lower vertical position, said lower vertical position being above the pick-up device;
- and
- a bottom clamping device arranged between the first upper position and the pick-up device and adapted to move selectively between a pinching position, adapted to pinch the tubular knitted article against the side wall of the reversing tube, and a position clear of the reversing tube.
