Abstract (en)
The invention relates to a system and method for subordinating a first electric motor (18) to a second electric motor (20). The system according to the invention provides for the use of a strip (2) which bears at least one series of marks spaced longitudinally thereof in a predetermined manner and is driven to move along its longitudinal direction by the second electric motor (20). A reading device (26) is fixed relative to the strip signals the passage of the said marks to control means (27) which supply the first motor (18) with a signal which is a function of the frequency of reading of the said marks, in order to vary the velocity of the first motor (18) with time according to a predetermined law linked to the speed of the second motor (20). The system is usable, for example, in a wrapping machine for confectionery products.
