Abstract

A yarn feed unit for a single-cylinder circular knitting machine comprises a plurality of yarn feeding fingers independently journalled to a common axis and independently movable between an inoperative and an operative position. The axis is supported by a carrier body which is radially displaceable with respect to the needle cylinder between a work position close to the needle cylinder and a rest position remote from the needle cylinder. Movement of the carrier body from the work position to the rest position causes the operative yarn feeding fingers to be simultaneously tilted into the inoperative position and all the yarn feeding fingers to be radially withdrawn from the needle cylinder, thus allowing rotation of the needle cylinder and needle dial to set the machine without any risk of damaging the needles and without manually handling the dial needles.

Claims5

Dependent claims

An improved yarn feed unit in a single-cylinder circular knitting machine, in particular a hose or the like knitting machine, comprising a plurality of yarn feeding fingers arranged side-by-side and independently journalled about a common axis, said yarn feeding fingers being movable independently of one another between inoperative and operative positions, an arm journalled to said common axis and having a small plate secured thereto and extending underneath all of said yarn feeding fingers, means for raising said arm and along therewith, through the intermediary of said small plate, all of said yarn feeding fingers at once to a rest position substantially coincident with said inoperative position, a carrier body supporting said axis, means for substantially radially displacing said carrier body between a position close to said needle cylinder and a position remote from said needle cylinder, said means for raising said arm being operative upon said carrier body being displaced to said position remote from said needle cylinder.
