Automatically carding machine

Types of automatically carding machines

According to the latest report on India Cotton Carding Machine Market, the market will grow at 3.89% CAGR during the period from 2021 to 2027. Automatically carding machines play a pivotal role in the early-stage processing of cotton and are expected to increase in demand.

An automatic carding machine is a piece of carding machinery for fiber that scans and opens mass fiber. This machine is usually used as the first step to preparing fiber for yarn spinning. The purpose of these machines is to divide the jumbled fill into its separate parts. They do this by removing impurities and aligning the fibers to make them easy to spin into yarn or thread.

Carding machines by design:

• Condenser carding machine: This machine works on the concept of flat and cylindrical pairs of cards exercising a carding action. It is comprised of a carding zone, drawing zone, and condenser zone. The cotton is opened and cleaned in the carding zone where seeds and other trash are removed in the drawing zone. In the third, or the condenser zone, the sliver is slightly twisted and dried. The advantage of this type of carding machine is that a consistent sliver with good quality can be produced at high throughputs.
• Flat carding machine: Flat carding machines comprise a flat card conveyor belt and a round carding roller or cylinder. Flat carding machines groom fiber tufts, remove debris, and align fibers for spinning. They produce a sliver of fiber that's homogenized and ready for the next stage of production. This automatically carding machine is best suited for processing cotton with medium to fine counts. The slivers produced are of average quality but good capacity and speed.
• HI-Cap carding machine: High-Production HI-Cap carding machines are designed to handle large volumes of material quickly and efficiently, making them ideal for high-capacity production environments. Relying on the 'card and draw' principle, HI-CAP Cardings also feature the unique process of 'segmental extraction.' In this process, the carded cotton is extracted in segments, i.e. in tray inserts, which are easier to handle and process later. A big advantage of HI-Cap machines is their great efficiency. They have been specifically designed to achieve optimum production from every pound of energy used.
• Pneumatic carding machine: This machine uses a pneumatic system in the carding process. In simple terms, the air movement and flow suction used will help release the carded fibers in a sliver formation. The advantage of this carding machine is that noise pollution is low during the operation of the machine.
• Roller carding machine: This automatic carding machine is often referred to as the 'flyer and rollers' carding method. It also comprises a feeding tray, carding parts, a sliver forming part, and a drafting arrangement. However, the design varies greatly from flat carding machines. In roller carding machines, the cotton fiber is pulled by a drafting mechanism and carded by rotating rollers fitted with cards and brushes. The advantage of a roller carding machine is that this method is actually more suitable for carding wool or worsted.
• Rotor carding machine: One of the newer developments in carding technology, rotor carding machines, works on the principle of a central rotor or wheel that fluffs and aerates the cotton. The rotor draws in the batt which is beaten on the drum. The loose fiber is drawn out through the grid. This works on a similar principle as the blow room and is used for pre-card cleaning of the cotton. The advantage of a rotor carding machine is that it works on a cleaner batt at a higher speed. It's especially handy when unprocessed cotton is used directly in the carding machine.
