ABSTRACT:
The invention pertains to a tension regulator for elastic tape and the like, particularly in sewing machines adapted to attach tape to a workpiece.
This regulator substantially consists of an electromechanical transducer on which the stress produced by tensioning the tape causes a mechanical deformation converted into an electrical signal; this electrical signal, suitably processed, controls a motor means which acts so as to feed or take up tape in order to keep the tension of the same at a constant value.
