Abstract

A needle-holding unit (1) for circular knitting machines, having a structure shaped as a hollow solid of rotation developing around a central axis (Z), and being configured for turning around said central axis and for supporting a plurality of needles (N) moving so as to produce a knitted fabric. The needle-holding unit exhibits on an outer side at least one working surface (2), on which a plurality of needle seats (3) is defined, which are placed beside one another and arranged around the central axis; each of the needle seats movably houses at least a portion of at least one respective needle (N) which can be actuated with an alternate motion along the respective needle seat with a motion of extraction and a motion of return, in order to produce knitted fabric. Each needle seat (3) has an inclined longitudinal development with respect to the central axis (Z). The working surface (2) has a shape as a surface of rotation obtained through the rotation of the inclined needle seats (3) around the central axis, and in particular the working surface is a non-cylindrical non-conical three-dimensional surface.

Description

technical field [0001] The invention relates to a needle holding unit for a circular knitting machine and to a circular knitting machine comprising such a unit. [0002] In particular, the present invention relates to a needle-holding cylinder or plate designed to be introduced into a knitting machine, characterized in that its seats are of a particular configuration to accommodate the needles of the knitting machine. The invention may further relate to a circular knitting machine comprising a needle holding unit with a specific structure and further components, such as a control unit, needles, etc. [0003] The present invention belongs to the technical field of circular knitting machines for knitted articles, seamless knitted articles, knitted articles and the like. [0004] In this context, the term "knitting machine" generally refers to a circular knitting machine, which is apt to manufacture knitted items and is provided with at least one needle-holding unit, i.e., with ...
