Process for making an upper for shoes with advanced technical characteristics

Abstract

The process for making an upper for shoes with advanced technical characteristics, consists in knitting a first part of the upper with a group of needles having an overall maximum number of needles in a tuck stitch or loop position or in a plain drop stitch position or in a missed stitch position, the maximum number of needles being equal to the number of needles present in a cylinder of a circular knitting machine.

1 . A process for making an upper for shoes, comprising the following steps:
 during the movement between successive reversals in the knitting machine, knitting a first part of the upper having a perimeter edge simultaneously with a group of needles of said machine having an overall number of needles in a tuck stitch or loop position or in a plain drop stitch position or in a missed stitch position, which may vary up to the number of needles present in said machine; and,   during the movement between successive reversals in the knitting machine, knitting the second part of the upper having a perimeter edge simultaneously with a group of needles of said machine having an overall number of needles in a tuck stitch or loop position and/or in a plain drop stitch position and/or in a missed stitch position, which may vary up to the number of needles present in said machine;   wherein that said second part of the upper is knitted before or after said first part of the upper; and   iwherein that the complete upper is unloaded from said machine with the connection of the perimeter edge of the part knitted after to the perimeter edge of the part kitted before having already been made simultaneously with the formation of the part knitted after.   
     
     
         2 . The process according to  claim 1 , wherein said machine is a circular knitting machine. 
     
     
         3 . The process according to  claim 1 , wherein said first and second part of the upper define at least a three-dimensional pouch for simultaneously containing the tip and the heel of the user's foot. 
     
     
         4 . An upper for shoes, comprising a first and a second part, each knitted by a group of needles that works with a maximum number equal to the number of needles present in a needle-bearing cylinder of a circular knitting machine.
