Abstract
A carding machine includes clothed rolls for processing and carrying fiber material thereon; an arrangement for separating lightweight waste from the fiber material processed by the clothed rolls; a conduit for receiving the lightweight waste; an air stream generating arrangement for generating an air flow in the conduit for removing the lightweight waste; an adjusting device for varying a degree of carding intensity of the carding machine; and a detecting device for measuring quantities of the lightweight waste produced at a respective degree of carding intensity.
Claims12
A carding machine comprising:
- (a) clothed rolls for processing and carrying fiber material thereon;
- (b) means for separating lightweight waste from the fiber material processed by the clothed rolls;
- (c) a conduit for receiving the lightweight waste;
- (d) air stream generating means for generating an air flow in said conduit for removing the lightweight waste;
- (e) adjusting means for varying a degree of carding intensity of said carding machine;
- and
- (f) detecting means for measuring quantities of the lightweight waste produced at a respective degree of carding intensity.
A method of measuring lightweight waste in a carding machine, comprising the following steps:
- (a) processing fiber material by clothed rolls;
- (b) separating lightweight waste from the fiber material processed by the clothed rolls;
- (c) introducing the lightweight waste in a conduit;
- (d) generating an air flow in said conduit for carrying the lightweight waste;
- (e) varying a degree of carding intensity of said carding machine for setting a degree of gentle carding and a degree of aggressive carding;
- (f) measuring quantities of the lightweight waste produced at a degree of gentle carding;
- (g) generating first signals representing measured quantities of the lightweight waste produced at a degree of gentle carding;
- (h) measuring quantities of the lightweight waste produced at a degree of aggressive carding;
- (i) generating second signals representing measured quantities of the lightweight waste produced at a degree of aggressive carding;
- and
- (j) comparing said first and said second signals with one another.
