Abstract

A device for feeding yarn to a knitting machine comprises a yarn guide and a drive pulley with a yarn feeding roller, mounted on a shaft for rotating said shaft. The yarn feeding roller is defined by two discs being provided, each of said discs, on the side facing the interior of the yarn feeding roller, with slots arranged symmetrically in relation to a plane perpendicular to the rotation axis of the yarn feeding roller. An elastic band runs between the discs in the respective opposing slots and forms the yarn feeding surface of the roller with a variable diameter. Spaced from the yarn feeding roller and mounted in a stationary position in relation thereto is a yarn guide in the form of a rod having its upper portion disposed at an angle to the rotation axis of the yarn feeding roller, and its lower portion disposed parallel to this axis for steady guiding yarn loops along the yarn feeding surface of the roller with a variable diameter.

Dependent claims

A device for feeding yarn to a knitting machine, comprising:

a shaft rotatably mounted in a housing;
a drive pulley mounted on said shaft for rotating said shaft;
two spaced apart discs mounted on said shaft;
slots in said discs on the sides facing each other and arranged symmetrically in relation to a plane perpendicular to the axis of said shaft;
an elastic band positioned between said discs in the respective opposing slots;
said discs and said elastic band defining a yarn feeding roller, wherein the elastic band serves as a yarn feeding surface with a variable diameter on moving the elastic band along the slots of the discs;
and a yarn guide mounted in a stationary position in relation to said yarn feeding roller and spaced therefrom;
said yarn guide being in the form of a rod having its upper portion disposed at an angle to the rotational axis of the yarn feeding roller, and its lower portion disposed parallel to this axis, whereby a change in the speed of feeding yarn and the uniformity of its tension depends on a change in the diameter of the roller.
