Furthermore, disadvantageously, the properties of the radial airflow (especially the air velocity) are related to the rotational speed of the rollers and cannot be controlled and adjusted independently of the rotational speed of the rollers

Embodiment Construction

[0038] figure 1 A carding machine with double outlet is shown for the production of non-woven fabrics, especially those with synthetic fibers such as polypropylene, polyethylene and / or natural fibers such as cotton and / or man-made fibers such as viscose as the main component. spinning.

[0039] figure 1 The shown carding machine comprises a carding machine inlet 1, which generally consists of a trough 1a, a feed roller 1b and a carding drum 1c. The carding drum 1c feeds a first rotating carding drum 2, commonly referred to as a guide drum, with a carding skin (in the form of needles or any other equivalent) around its periphery, allowing it to escape from the carding. The perimeter of the drum retrieves the fibers. Typically, a number of consecutive carding assemblies 3 are mounted on the upper portion of the guide roller 2 at its periphery. Each carding assembly 3 consists of a cleaning roller 3a and a working roller 3b. Each carding assembly 3 cooperates with the guid...

Abstract

A carding machine is provided with at least one swiveling roller (5), at least two lateral plates (F) installed on both sides of the roller and least one fixed fairing (11). The fairing is installed at a position that is close to the roller. At least one area around the roller is covered by the roller (5). Every side face of the roller (5) limits a lateral chamber (E) with every lateral plate andthe fairing. The lateral chamber (E) positioned at the joint between the fairing (11) and the lateral plate (F) is sealed by a seal ring (10). The carding machine comprises a first device (15, 9e) positioned outside the lateral chamber and can supply the lateral chamber (E) with air. The first device had better go through the lateral plate (F) and is connected with the lateral chamber (E). In use, every lateral chamber is pressurized to form a blast chamber. The blast chamber produces airflow towards the outside of the lateral chamber and the airflow well prevents fiber from entering.

Description

technical field [0001] The present invention relates to the field of the textile industry and aims at the improvement of textile machines commonly referred to as "cards", with the aim of reducing the blocking phenomenon of the card, which occurs in the accumulation of fibers in the lateral parts of the main rollers of the card. Background technique [0002] Usually, a carding machine has a plurality of cylinders, of which at least one is a carding cylinder (commonly called a large cylinder), which is provided with a carding cover on its peripheral surface and around which carding elements are mounted on the upper side. During work, the fibers are input into the carding machine in the form of a thick stack of fibers, and are separated one by one at the periphery of the carding roller through the combined action of the carding part and the carding skin around the carding roller (carding action). [0003] In general, as a non-limiting example, a carding unit consists of one or...
