Abstract

The invention relates to a method and apparatus for the automatic lubrication of the links of continuously moving material transport chains in a tensioning machine. The supply of lubricant is switched on and off for the duration of at least one complete circuit of the transport chain as a function both of the speed at which the chain goes round and the prevailing temperature in the tensioning machine, while an pulse count signal which is proportional to the speed at which the chain goes round and is used to control the supply of lubricant is multiplied by a multiplication factor formed from an actual value for the temperature, so that optimum lubrication of the chain links is provided.
