摘要:
An apparatus for automatically feeding tubular articles comprising elements (12) for feeding an article (3), which are adapted to fit an axial end (3a) of the article which is provided with a border (5) thicker than at least one adjacent portion (3b) of the article on grip means (6) which can be actuated in order to engage within the axial end so as to support the article in a substantially vertical arrangement and in order to produce a spacing of two diametrically opposite regions of the axial end (3a) transversely to the axial extension of the article. The apparatus also comprises elements (7) for supporting the article, which form a first slit-like passage (8) arranged substantially horizontally and adapted to receive a portion of the article that is arranged below the border (5). Elements (9) for tensioning in a downward direction the article inserted in the first slit-like passage are also provided. The supporting elements and the tensioning elements are movable on command in order to insert the portion (3b) of the article that lies directly below the border along a second slit-like passage (11) formed by two side-by-side guides for feeding a sewing machine. The method carried out by the apparatus.
摘要:
A conveyor for sewing machines for closing the tip of hoses or the like, having high-versatility use. The conveyor comprises a pair of substantially horizontal and co-planar flat strips which are laterally adjacent to each other and have, on their mutually facing sides, a pair of protruding ridges which laterally delimit a passage for a portion of the hose, proximate to the tip, which is knitted with a reduced thickness with respect to the contiguous regions. Each ridge has, along the advancement direction of the hose along the passage, an initial portion and a final portion which are substantially parallel, are mutually spaced and are joined by an inclined intermediate portion. An element for advancing the hose along the passage are provided above the flat strips at the passage. The advancement means can move in a direction which is substantially perpendicular to the plane of arrangement of the flat strips.

A sock positioning device, particularly for short socks, in labeling machines of the type comprising a conveyor belt (2) which can move along an advancement direction and with at least one station (4) for applying a label (5) at the tops (6) of a pair of mutually superimposed socks (7) arranged so that their tops (6) are proximate to a lateral edge (8) of the conveyor belt (2); the pair of socks (7) is deposited on the conveyor belt (2) so that the feet (9) are folded onto the legs (10), orientated transversely to the advancement direction, and so that the end portion (9a) of the feet on the toe side is folded again onto the remaining part (9b) of the feet (9) in order to keep the label application region clear. The positioning device (1;1a) comprises overturning means (12a, 12b) which can be arranged downstream of the application station (4), along the advancement direction of the conveyor belt (2), and are suitable to act on the folded end portion (9a) of the feet (9) in order to fully extend the feet (9) onto the legs (10) of the socks (7).

The machine comprises a needle (1) with an open eye (2) orientated perpendicular to a supporting surface (3) for the sewn item (4) and actuated with reciprocating motion to pass cyclically through the supporting surface and the sewn item, carrying a thread loop; a thread take-up wheel (5) having a fixed part (6), with a magazine (8) for taken-up thread (12), and a rotatable part (7); a lower looper (11) engaging the thread loop below the supporting surface (3) and loading the thread (12) into the magazine; and comprises a thread handly unit (31,32) allowing correct formation of the stitches.
摘要:
A method of making quick overlockings comprises the steps of manufacturing a band with at least one course of the knitted fabric made of an elastic yarn for producing a fold along said one course; folding back the band along the fold for juxtaposing it with a knitted element to which it is to be applied; sewing knitted element and edge close to the elastic course. In addition, in accordance with the invention, a band for quick overlocking is provided for being folded back to form at least one fold (15) along which it is to be sewn to a knitted element (12) to be trimmed therewith. At the fold position, the band is formed with a course (14) of knitted stitches made of an elastic yarn so as to promote folding.

Each ridge has, along the advancement direction of the hose along the passage, an initial portion and a final portion which are substantially parallel, are mutually spaced and are joined by an inclined intermediate portion. An element for advancing the hose along the passage are provided above the flat strips at the passage. Above each one of the ridges, starting from a region of their initial portion, there is a lamina which can move towards or away from the corresponding ridge and forms a resting surface for the upper border of the thinner portion of the hose.
