Mechanism and the method to reversing the tubular textile

Abstract

A mechanism and the method for reversing a tubular textile, such as sock, is performed when the plaiting process is finished and removed from the needles of the knitting machine for open-end closure.

What is claimed is: 
     
         1 . A mechanism for reversing a tubular textile with an open-end comprises: a vertically extending air suction hose, an air suction means connected to the air suction hose for generating air suction which is characterized in that:
 its including a drive source for moving the air suction hose up and down, a guide means mounted inside of the air suction hose and protruding down beneath a lower end of the air suction hose as a passage for the textile, and a vertical elongating hold means disposed down below the air suction hose for receiving the textile from the guide means.   
     
     
         2 . A reversing mechanism as defined in  claim 1 , wherein the guide means comprises at least two vertical extending rods coaxially arranged inside of the air suction hose. 
     
     
         3 . A reversing mechanism as defined in  claim 2 , wherein the guide means further comprises a collar deployed on a lower end of the rods. 
     
     
         4 . A reversing mechanism as defined in  claim 3 , wherein the hold means is a prolonging rods projecting to the center of the collar. 
     
     
         5 . A reversing mechanism as defined in  claim 1 , wherein the hold means is a longitudinal rods directing to an axis of the collar. 
     
     
         6 . A reversing mechanism as defined in  claim 1 , wherein the hold means has a shaft for pivoting movement. 
     
     
         7 . A reversing mechanism as defined in  claim 1 , wherein the hold mean makes a vertical movement. 
     
     
         8 . A reversing mechanism as defined in  claim 1 , wherein the air suction hose is movably deployed on a body equipped with a drive source in charge of moving the air suction hose. 
     
     
         9 . A reversing mechanism as defined in  claim 8 , wherein there are two pulleys disposed between the body and the drive source, and a timing belt connected to the pulleys for power transmission. 
     
     
         10 . A knitting machine for producing a tubular textile includes a bracket, and a reversing mechanism as defined in  claim 1 . 
     
     
         11 . A knitting method for reversing a tubular textile includes following steps:
 a) take off the tubular textile from a needle of a knitting machine;   b) reverse the tubular textile by operation of a reversing mechanism as defined in  claim 1 ;   c) sew off the open-end of the tubular textile on a sewing station; and   d) overturn the tubular textile by using the reversing mechanism.   
     
     
         12 . A reversing method as defined in  claim 11 , wherein the step b) reversing process may be carried on before transferring to the sewing station. 
     
     
         13 . A reversing method as defined in  claim 11 , wherein the step b) reversing process is operated on the sewing station. 
     
     
         14 . A reversing method as defined in  claim 11 , wherein the step b) includes following steps:
 b1) an air suction hose of the reversing mechanism passes through a lower end of the textile and moves downward;   b2) the air suction hose moves downward until reaches a position lower than the open-end of the textile;   b3) activate an air suction means of the reversing mechanism;   b4) the air suction hose moves upward; and   b5) the textile is sucked into the air suction hose for reversing process.   
     
     
         15 . A reversing method as defined in  claim 11 , wherein the step d) includes the following steps:
 d1) a hold means is shifted beneath the textile with the open-end closed;   d2) the air suction hose moves downward tag along the textile with the open-end closed; and   d3) the textile is released from the air suction hose but retained by the hold means.   
     
     
         16 . A reversing method as defined in  claim 15 , wherein the step d3) includes upward moving the hold means.
