Abstract
A carding machine comprises a main carding cylinder and parts which are adjustable relative thereto, such as a licker-in, a stationary flat, a revolving flat and a doffing cylinder, such parts preferably having a nominal spacing relative to the main carding cylinder. For checking a spacing, namely an existing spacing or an already adjusted spacing between the main carding cylinder and the aforesaid parts arranged opposite thereto, there is provided a sensor at at least one end or end portion of the main carding cylinder, but preferably at each one of the two ends or end portions thereof, such sensor or respective sensors being connected to an electronic evaluation unit by means of a coupling device.
Claims22
A carding machine comprising
- a main carding cylinder having two end portions;
- a predetermined number of carding-machine parts which are adjustable relative to said main carding cylinder;
- a predetermined number of carding-machine parts which are adjustable relative to said main carding cylinder;
- said predetermined number of carding-machine parts each defining a respective nominal spacing relative to said main cylinder;
- sensor means provided at at least one end portion of said two end portions of said main carding cylinder for rotation therewith for sensing the spacing of said carding cylinder from at least one of said carding-machine parts;
- electronic evaluation means;
- coupling means for coupling said sensor to said electronic evaluation means;
- said coupling means constituting at least one slip ring for said sensor;
- and
- said at least one slip ring serving for reading out signals which arise and for selectively providing said sensor with at least any one of electrical energy or measuring pulses.
A carding machine comprising:
- a main carding cylinder having two end portions;
- a predetermined number of carding-machine parts which are adjustable relative to said main carding cylinder;
- said predetermined number of carding-machine parts each defining a respective nominal spacing relative to said main cylinder;

- said main carding cylinder adapted to rotate at a predetermined rotational speed;
- a predetermined number of carding-machine parts which are adjustable relative to said main carding cylinder;
- said predetermined number of carding-machine parts each defining a respective nominal spacing relative to said main cylinder;
- sensor means provided at at least one end portion of said two end portions of said main carding cylinder for rotation therewith for sensing the spacing of said carding cylinder from at least one of said carding-machine parts;
- electronic evaluation means;
- coupling means for coupling said sensor to said electronic evaluation means;
- a counter-element provided at each one of said predetermined number of carding-machine parts and arranged opposite said sensor;
- said sensor means having a predetermined measuring position;
- each said counter-element cooperating with said sensor means at least at said predetermined measuring position thereof;
- means for synchronizing said electronic evaluation means to said predetermined rotational speed of said main carding cylinder such that an allocation of signals of said sensor means to respective carding-machine parts of said predetermined number of carding-machine parts is effected;
- and
- means for generating a trigger signal to facilitate said allocation of said signals of said sensor means;
- said means for generating a trigger signal being structured such that said counter-element provided at each one of said predetermined number of carding-machine parts constitutes two counter-elements arranged at tandem.
A method of checking the spacing between a main carding cylinder having opposite end portions and at least one carding-machine part arranged opposite the main carding cylinder, the main carding cylinder having sensor means mounted thereon for rotation therewith and a signal transmitting device thereon for rotation therewith for coupling the sensor means to an electronic evaluation means, the method comprising the step of:
- measuring the spacing between the main carding cylinder and said carding-machine part with said sensor means on said main carding cylinder by transmitting signals by means of said signal transmitting device by means of wave to a signal receiving means.
