Description

one

This invention relates to a process of combing fibrous materials and can be used on carding machines in the textile industry.

A known method of making a batt, which allows carding of the fibrous material on the main drum of the cheshny machine, followed by the removal of the batt with a removable drum l.

In the process of combing fibrous materials according to a known method on carding microbes, the most frequent defects are in the form of ragged edges of the carding.

The aim of the invention is to improve the quality of the batt.

The goal is achieved by combing the fibrous material at the junction of the batting from the main drum to the removable from the ends of them, a stream of compressed air is fed under a pressure of 0.1 to 1.0 kgf / cm in a direction parallel to the surface of the main drum below the line of approach of the drums. .

FIG. 1 shows a device implementing the proposed method, side view} in FIG. 2 the same, top view.

The device contains a main drum 1, a removable drum 2, a lattice 3 of the main drum, a tube 4 of a half of compressed air, a place 5 of the closest approach — the main drum 1 with a removable drum 2.

The method is carried out as follows.

During the work of carding MCshina

 through the tubes 4, a stream of compressed air that prevents the down from accumulating on the edges of the grille 3 and improves the transition of fibers from the needle surface of the main drum 1 to the needle surface of the removable iaraSana 2. From a common compressor or from

3Q compressor installed on the carding machine, serves compressed air under pressure up to 1 kgf / cm through the air ducts to the ends of the main 1 and removable 2 drums in zones close to places 5

25 of their closest approach, but no closer than 5 mm, established by experiments and observations. The use of the proposed method on carding machines eliminates the stopping carding

30 machines for eliminating torn edges

manually, thereby improving labor productivity and equipment and improving the quality of the card,

Example. Compressed air under pressure from 0.3 to 0.8 kgf / cm is fed through tubes F with a diameter of 3.5 mm, installed at the ends of the main and removable drums, at the point of their closest approach in parallel to the forming surfaces at a distance of 35 mm below the axis plane rotation of the drums, as a result of which the card goes uniformly, without torn edges, the unequalness of the combing tape is reduced by 20-30%.
