Abstract
The grinding device is constructed with a grinding member which is biased elastically against the teeth of the clothing of a carding machine during operation of the machine. During grinding, the grinding member is capable of three degrees of freedom of movement under the elastic biasing force. In one embodiment, individual grinding stones are used as the grinding members. In another embodiment, an elongated flexible belt having a grinding coating is used as the grinding member and is biased by means of a tube containing pressurized fluid.
Claims23
A grinding device for the clothing of a carding machine element, said device comprising
- a support;
- at least one grinding member for grinding the teeth of a carding machine element, said member being mounted on said support with three degrees of freedom of movement;
- and
- means elastically biasing said grinding member outwardly of said support to engage the teeth of a carding machine element.
A grinding device for the clothing of a carding machine element, said device comprising
- a support;
- at least one grinding member for grinding the teeth of a carding machine element;
- first means mounting said grinding member in said support for pivoting about two perpendicularly disposed axes;
- and
- second means elastically biasing said grinding member outwardly of said support along a third axis perpendicular to said two axes whereby said grinding member has three degrees of freedom of movement.
A grinding device for the clothing of a carding machine element, said device comprising
- an elongated support of trough shape having an open side;
- a flexible grinding member secured to and extending across said open side of said support in hermetically sealed relation for movement in three directions at right angles to one another;
- and
- means elastically biasing said grinding member outwardly of said support.
In combination,
- a carding machine element having a clothing of teeth thereon;
- and
- a grinding device for grinding said clothing, said device including a support having a pair of side walls extending in close relation to said clothing, a grinding member mounted on said support and between said side walls for a movement therebetween having three degrees of freedom, and means biasing said grinding member out of said support towards said machine element for grinding of said clothing.
A method of grinding the clothing of a carding machine element comprising the steps of
- positioning a grinding device having a grinding member mounted therein for movement in three directions at right angles to one another over a carding machine element having a clothing of teeth thereon;
- and
- biasing the grinding member towards the carding machine element during operation of the element to effect grinding of the clothing thereof while continuously adjusting to the shape of the generated surface of the tips of the teeth of the clothing.
