The indicated parth of power transmission is known as the power transmission chart. It clearly reveals themanner of action of a machine.

1.2.1.2. Flow of Substance

A flow of substance (substance transport) takes place in working and power machines that use substances asenergy carrier.

Substance carriers hold the substance that is to be processed, worked or transported by positive ornonpositive action. Often the working assemblies, or one of their working elements, take on the function ofthe substance carrier.

Differing substances require differing methods to deal with them within the flow of these substances, e.g.:

Collecting (winding, bagging, stacking)

Conveying (pumping, pouring, scooping)

Arranging (distributing, sorting, aligning)

Branching of the flow of substance is often necessary in a machine or in a group of machines.

The representation of substance transport in a machine or installation is known as the substance flow chart(fig. 1/5).
