SU33521A1 - Sliding bobbin - Google Patents

Description

Extendable bobbins are known, consisting of perforated cheeks articulated with legs that can be moved with a screw, in order to constrict and expand the cheeks. In the proposed sliding bobbin forefoot, the cheeks, for the purpose of moving and expanding or constricting them, are provided with longitudinal grooves with holes and protrusions made in the form of an inclined plane in contact with the same plane formed by the thickening of the rod fitted with a nut in the upper part.

The proposed sliding bobbin barb is designed to shrink yarn on reels in Brandwood dyeing machines. He left the principle of Brandwood when putting on, dyeing and removing coils from the warp, the proposed design aims to simplify the articulated bobbin line, replace nickel with iron, make it more durable and finally simplify and reduce the cost of production.

In FIG. 1 shows a longitudinal section on the left, and on the right is a view of top 30

her part is navo; FIG. 2 - top view; FIG. 3-section and frontal view in the places of thickening of the rod; FIG. 4 is a section along the line AB in FIG. 3; FIG. 5-cheek surface.

In contrast to Brandwood's navo, instead of four mesh nickel-cheek cheeks, the proposed navoy has three pig-iron cheeks 7 (fig; 2), cast with eight longitudinal grooves 13 (fig. 5) with oval holes // and with protrusions 9. Tooth ends W (fng. 4), between which furrows 13 are formed, are machined on a grinding machine. The projections 9 (on the inside of the cheek) are also machined to form the inclined plane 5 (Fig. 3). This cheek plane / slides when the special nut .5 is rotated (Fig. 1) along the planes formed on the thickenings 7 of the rod b. Thus it is possible the separation and contraction of the war. The thickening of the rods are machined cylindrically and the grooves are selected on them in a milling cutter or on a planer, forming an inclined plane 6. The rods can be

made of steel or iron, and on the one hand supplied with a thread for nut 5 made of nickel silver, nickel or cast iron. Rods, like those of Brandwood, are provided with a thread from the bottom side, with the help of which they are fastened on the flange to the side. In order to allow the cheeks to freely disperse, and at the same time be held together, the pins 4 are screwed in their upper part, which freely pass through the oval holes 3 in the washer 2.

The movement of the dyeing solution of either water or air (when blowing bobbins) occurs at the beginning, like in Brandwood: bottom-to-bottom m / 2, then through the holes // it gets into the furrows 75 and the latter is distributed along the inner surface of the reels. The furrows / J must be, in comparison with the width, deep so that the stocking, which is usually placed under the bobbin, under pressure from the outside, could not close the furrows to the full depth, and the channel would remain

sufficient section for fluid distribution. In case the postpainting paint after the staining and would not become narrow, it is fitted in the upper part with a cone J4 {fig. 1), which can be filled with a ring.

The subject matter of the invention.
