Abstract
A device for checking the presence of slivers in carding
machines and the like comprises: a number of piezoelectric
feeler units equal to the number of slivers to be checked, and
on which said slivers are simply rested and slide during their
movement, said feeler units converting the mechanical
vibrations produced by the movement of the slivers on said
units into oscillating electrical signals; a switchable channel
fed by said piezoelectric feeler units and conveying to a
single output at different moments of time the signals which
reach the channel at separate inputs; a single signal
amplifier tuned to the frequency range produced by the
feeler units; a selection circuit which chooses only one feeler
unit at any given moment and connects it to the amplifier;
and an actuator circuit which integrates the signal originat
ing from the amplifier and produces a stop signal and or
activates alarm means if one or more of the signals
originating from the feeler units are indicative of a broken or
absent sliver.
