Abstract
A grinding device for the flats of a card comprises elastically bendable elements which enter between the card clothing points, brush across the lateral surface of the points and thus grind them, whereat the material that has been ground off is removed by a suction means. The grinding device may be portable so as to be used on different card machines. A control system may be provided to engage and operate the device in an interrmitten manner.
Claims16
A grinding apparatus for grinding individual clothing elements of a set of moving flats in a textile machine, the clothing elements having a head portion defined by a bend or knee in each element, said grinding device comprising:
- individual bristlelike elastic bendable elements mounted on a support so as to extend radially therefrom, said elements having a length and size so as to penetrate between the clothing elements without extending beyond a head portion of the clothing elements;
- and
- a drive connected with said element support to rotate said support at a speed and in a linear direction only with respect to movement of the flats such that said bendable elements can sweep over and between free ends of said clothing elements from behind and laterally grind side surfaces of the clothing elements.
A grinding apparatus for grinding individual clothing elements of a set of moving flats in a textile machine, the clothing elements having a head portion defined by a bend or knee in each element, said grinding device comprising:
- elastic bendable elements mounted on a support, said elements having a length and size so as to penetrate between the clothing elements without extending beyond a head portion of the clothing elements;
- a drive connected with said element support to move said support such that said bendable elements can sweep over and between free ends of said clothing elements and laterally grind side surfaces of the clothing elements;
- and
- a control system configured to intermittently engage and operate said apparatus during specific time periods of operation of the textile machine.

- elastic bendable elements mounted on a support, said elements having a length and size so as to penetrate between the clothing elements without extending beyond a head portion of the clothing elements;
- a drive connected with said element support to move said support such that said bendable elements can sweep over and between free ends of said clothing elements and laterally grind side surfaces of the clothing elements;
- and
- a shifting device configured at a grinding location where the clothing elements are ground by said elastic bendable elements, said shifting device disposed in the path of travel of the moving flats so as to contact and move the flats towards the elastic bendable elements as they move through said grinding location.
