Carding plates or carding bars

Index

The other or additional method of intensifying the carding effect is the insertion of  carding elements at special positions.

Today, carding aids can be applied at three positions:

These aids are in the form of carding plates or carding bars.

Carding plates have already been illustrated in Fig. 99 at the licker-in, while carding bars are shown in Fig. 102 and Fig. 103.

Plates are usually used in the licker-in zone, while bars are being located increasingly in the region of the main cylinder (Fig. 102 and Fig. 103).

An aluminium carding profile (1) consists of 2 carding bars (2). One of the advantages of bars is that they can be provided in different finenesses, e.g. they can become finer in the through-flow direction. Different manufacturers use differing numbers of elements (between one and four) per position. Special clothing is required that must not be allowed to choke. Most modern high-performance cards are already fitted with these carding aids as integral equipment; all other machines can be retrofitted by, for example, Graf of Switzerland or Wolters of Germany.

In use are also other carding devices of different design and with different components, e.g. mote knives (4) with guiding element (5) and suction tubes (3), etc.
