SU33758A1 - Manual cotton banding device - Google Patents

Description

In the production of cotton ringing in practice, in the absence of a special tool, an ordinary knife must be used, which performs the ringing operation extremely slowly and with a high risk of damage to plants due to damage to the cambi. The production of ordinary leather skins by unskilled workers is associated with such large losses that nullify the experimental data. The proposed manual cotton ringing device is designed to ensure that ringing is carried out correctly even by unskilled workers.

In FIG. 1 shows a detail of the cutting part of the device, and FIG. 2 handle.

The manual ringing device consists of two spring plates, bent in the middle part in the shape of a semi-cylinder and equipped with cutting blades a (Fig. 1), and a handle 2 (Fig. 2). These plates are stamped from an iron strip according to the shape indicated in the drawing, and then quenched and refined.

curved by 0.5 g. and in the oval edges. Thus, on each plate there are three blades, two oval and, at a distance of approximately 1 cm from each other, facing: inside the cylinder formed by the bent parts and transverse b, placed on the end of the plate bent inward of the device and perpendicular to the blade. There are three holes in the bottom of the plate for attaching the handle to the handle. Both plates are joined together so that a full oval is formed in section, inserted into the handle and fastened to it with screws. Operation using the proposed device is performed as follows. Holding the device in hand, press it with its upper forked end into the stem of the plant to be ringed; the latter will pass between the plates that have spread to the sides and will be placed in an oval, squeezed by these plates, with the cutting blades and the edges of the oval 0.5 mm in the bark. Then, when turning the handle to the right and then to the left, the blades will make a circular cut.

the bark and at the same time transverse blades b, in the upper part of the oval, the notched bark is scraped off. After that, when the arm is held back, the stem of the plant is pulled out of the device ringed.

The subject matter of the invention.
