(Cl. 242-120) The object of the present invention is to provide an improved textile machine accessory, more especially a bobbinand weftcarrier constituted as a tapered mandrel which consists in large part of an artificial resin member adapted for manu-. facture by die-casting or injection molding.
A further object of the present invention consists in constituting the artificial resin textile machine accessory as a weft carrier adapted for use with the shuttles of automatic looms and as bobbin carriers said accessorybeing reinforced on its one end with a metallic ferrule at the end that is fastened in the shuttle and on the opposite end with a metallic cap.
In the accompanying drawing an embodiment of the invention is illustrated by way of example.
Figure 1 is a longitudinal section through a weft carrier for shuttles in the shape of a socalled Northrop bobbin as intended for automatic looms.
Figure 2 shows the upper end of the bobbin on an enlarged scale.
Figure 3 a cross-section taken on the line III--III of Fig. 1 and Figure 4 shows the lower end of the bobbin of Fig. 1 on an enlarged scale.
In the embodiment shown a designates a hollow and slightly conical tubular portion made of artificial resin of about 1.2 kg./dm. specific gravity, manufactured under pressure by any suitable die-casting or injection molding process. The upper end of the tube is protected by a metallic cap, preferablyof steel, while the artificial resin tube is reinforced at its lower end by a tempered steel ferrule a fitted with collars, external annular ribs, corrugations, Or the like a Such corrugations, ribs, or collars may be formed in or on the ferrule by any suitable procedure prior to its incorporation in the molded assembly. Cap a and externally corrugated or ribbed ferrule a are injection molded or die-cast integrally with the artificial resin member a. For this purpose the metal cap a and externally corrugated ferrule a" are preliminarily positioned in the die-casting mold, injection mold or the like and are inseparabl bonded under pressure integrally with the artificial resin material which, after cooling, solidifies. Interiorly, the artificial resin tubular body portion a is provided with internally projecting longitudinal ribs spline-like a three being preferably used, as shown in the drawing. These serve the purpose of stiffening the tubular body portion a for one thing, and for another thing serve as a seating means when the bobbin is thrust upon for winding.
The bobbin or weft carrier (composed of parts a, a, a", a and a is retained in, the shuttle in the usual manner by means of the collars a which, when the bobbin is in secured position, are encircled or grasped by strong springs of the shuttle.
Compared with prior art bobbins reinforced or provided with steel rings the above described artificial resin bobbin possesses the great advantage of having greater strength, greater surface hardness and absolute insensitivity to moisture, the latter feature being particularly essential when damp weaving is contemplated. On account of the above described integral die-casting or injection mold bonding of the artificial resin body portion with the metal cap and ferrule, of which externally corrugated ferrule a in contrast to the individually shrunk-0n steel rings of the prior art wooden bobbins, consists of one single unitary piece, an absolutely rigid and firm bonding together of the respective parts is ensured.
'Compared with all-metal bobbins the above described artificial resin bobbin is much lower in weight and moreover much less costly to manufacture. The artificial resin bobbin made by the die-casting or injection molding is also much cheaper, lighter and of substantially increased toughness; it possesses greater surface hardness, and is much less brittle than the prior art pressed bobbins made from artificial powdered resin which, after pressing, suffer heavy shrinkage thus precluding the securing of accurately sized bobbins.
Having now particularly described the nature of our said invention and in what manner the same is to be practised, I declare that what I claim is:
1. A textile machine accessory of bobbin-like configuration comprising a hollow tubular body portion of injection-molded artificial resin provided with internal splines a metal cap at one end of saidbody portion and an externally corrugated metal ferrule at the other end of said body portion, said metal cap and said ferrule being exteriorly disposed on and inseparably bonded to said body portion and said internal splines being integrally cast with said body portion.
2. A bobbin and weft carrier for use with spindles and shuttles of automatic looms and the like, comprising a hollow tubular body portion of injection molded artificial resin and having internal splines integrally molded with said body portion for operative engagement with a spindle or the like, a metal cap at one end and an externally corrugated ferrule at' the other end of said body 3 portion, said cap and said ferrule being externally disposed on and inseparably bonded to said body portion, said corrugated ferrule being adapted for effecting operative engagement of said bobbin with a shuttle.
