Continuous models carding machine

Continuous - in which no distinction is made with regards to structural elements of the physical objects or individual stages of the processes. For example, yam can be considered as a solid cylindrical body whereas fabric can be considered as a solid sheet material. Following this approach, the movement of a fibrous web through the carding machine can be modelled as a flow of a fluid where the interaction of the machine s working parts with individual fibres and fibres with one another is not taken into account. 

One of the methods applied for modelling a continuous transformation of an input product to the output product by a processing unit, where both are characterized by a variation in their properties, is based on the application of control theory and signal processing theory. The processing unit, e.g. carding machine, can be modelled as a linear time-invariant system where the transformation process is described by a dynamic characteristic called a transfer function ...
