[0004] Thus, despite the obvious automation advantages of this device, it has the disadvantage of having to interrupt the tubular article to insert it directly on the loop of needles and to convert the standard manufacturing process of the tubular article in its finishing dynamics for closed ends

Embodiment Construction

[0046] Referring to Figure 1- Figure 21 .

[0047] Said machine comprises a conventional tubular suture-making system, characterized in that a rotating ring of needles positioned in a conventional manner on a support cylinder is used to make the knitted tube. Due to the coaxial arrangement with respect to the aforementioned support cylinder, and thus the formation of the downward hollow sliding chamber, said hollow sliding chamber is suitably repositioned relative to the knitting machine by suitable means. Additional guides slide inside these tubes, inside the hollow stroke there is a guide system from the outer ring, which allows the same device to be accurately centered with respect to the making machine.

[0048] In one piece with the guide system there is provided a retraction mechanism 4 which essentially consists of a ring of retaining hooks 8 which is duly reduced in diameter and which is divided into two mirrored ones by a specific hinge 7 The reversible halves 5, 6,...

Abstract

The invention provides a system and a method in the production of stitch tubular products for the closing of the seam of the point of a tubular stitch product. The system consists of a circular knitting machine with a cylinder of needles; a tacking-on device with a rim of holding crooks; and a stapler arranged on the outside of the cylinder of needles and used to carry out the closing of the point. Characteristically according to an aspect of the invention is that the tacking-on device includes a body substantially circulate subdivided in two substantially specular portions, wherein each of them is equipped with a semi-arc of holding crooks. The specular portions are hinged around to the overturn axis which is substantially diametral, so as to obtain the overturning of a portion on the other and therefore to bring a semi-arc of oppositely holding crooks with the semi-arc of opposite holding crooks. In this arrangement the tacking- on device can allow the closing by the stitching or looping of the point, for example placing the stapler below the circular machine, in a position in which the tacking-on device is placed after having taken and extracted the tubular stitch product to sew from the circular machine.

Description

technical field [0001] This invention relates to the art of knitting machines, in particular machines for the production of stockings and socks. Such machines belong to a specific class of machines known as braiding circular machines for making tubular seamed products of arbitrary diameter and fiber quality. Background technique [0002] Hitherto, such machines have been characterized by continuous production with programmed programs setting lengths, types and joints which are turned over for finishing. The finishing is accomplished by forming a plurality of link lines (links) in the following manner through the loops formed by the knitting needles. When reworking, the various processes of stockings are separated to turn to closing the ends of stockings, which until now has been performed manually and mechanically as described below. [0003] More recently, the prior art has proposed automatic mechanical attachments applied with suitable interfaces of circular knitting mac...
