The movement adjuster comprises an actuator, connected to an adjustment cam and actuatable so as to turn the adjustment cam about its own axis through preset angles. The adjustment cam has a single external active profile, two cam followers being arranged on the slider to make contact with the active profile of the adjustment cam in two spaced points and cooperate in determining a bilateral coupling with the adjustment cam.

Abstract: A thread gripping device, for gripping elastic thin thread, in a circular knitting machines, having a supporting element that supports thread guides proximate to a drop or feed, above the needle cylinder and proximate to the needle work area, and bearing at least one elastic lamina element and a thread locking lever pivoted to the supporting element and to rotate scissor-like to catch the thread with a grip portion between the locking lever and the elastic lamina element. The thread gripping region of the locking lever is made of a material with higher friction coefficient, than the remaining part of the locking lever.

Abstract: A method for producing tubular items, such as hosiery items and the like, which are closed at an axial end, using a single-cylinder circular knitting machine provided with a half-dial which faces, in an upward region, a first half of the needle cylinder and has hooks which can move in a radial direction with respect to the axis of the needle cylinder, each hook being arranged between two contiguous needles of the half of the needle cylinder that it faces. The half-dial can turn over about a diametrical axis of the needle cylinder so that its hooks face the needles of the second half of the needle cylinder. The hooks can move in a radial direction with respect to the axis of the needle cylinder in order to engage portions of loops of knitting formed by the needles of the first half of the needle cylinder before the half-dial turns over and in order to release the portions of loops of knitting to the needles of the second half of the needle cylinder after the half-dial has turned over.

The hooks have a longitudinal slit which is open in the direction of the axis of the dial or half-dial body. The slit gives a portion of the body of the hooks a bifurcated shape which engages the two opposite faces of the dial or half-dial body.

Abstract: A needle actuation device for knitting machines, comprising a cam supporting surface which faces a needle supporting element and supports at least one casting-off cam which has a profile arranged at an angle to the direction in which the needle supporting element moves with respect to the cam supporting surface during the operation of the machine.
