Abstract
Abstract There is disclosed an apparatus for cutting a through passing lengthwise displaceable strand of material, especially a textile yarn, which incorporates a displaceably guided cutting knife means having a cutting edge portion. An anvil body means providing an anvil surface is rotatably mounted in a position to cooperate with the cutting knife means. The anvil body means is formed of a material possessing less hardness than the material forming the cutting edge portion. Drive means serve to advance the cutting knife means with its cutting edge portion against the anvil surface. The rotatably mounted anvil body means is contacted by the lengthwise displaceable strand of material in such a way that during each cutting operation the anvil body means carries out a partial rotational movement in order to expose a different portion of the anvil surface for the next cutting operation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
An apparatus for cutting a throughpassing lengthwise displaceable strand of material, especially a textile yarn, comprising a displaceably guided cutting knife means having a cutting edge portion, a rotatably mounted anvil body means providing an anvil surface positioned to cooperate with said cutting knife means and its cutting edge portion, said anvil body means being formed of a material possessing less hardness than said cutting edge portion, drive means for advancing said cutting knife means with its cutting edge portion against said anvil surface, said rotatably mounted anvil body means being contacted by the lengthwise displaceable strand of material such that during each cutting operation said anvil body means carries out a partial irregular rotational movement.
Claim 2
Independent Claim
116 words
An apparatus for cutting a throughpassing lengthwise displaceable strand of material, especially a textile yarn, comprising a displaceably guided cutting knife means having a cutting edge portion, a rotatably mounted anvil body means providing an anvil surface positioned to cooperate with said cutting knife means and its cutting edge portion, said anvil body means being formed of a material possessing less hardness than said cutting edge portion, drive means for advancing said cutting knife means with its cutting edge portion against said anvil surface, said rotatably mounted anvil body means being contacted by the lengthwise displaceable strand of material such that during each cutting operation said anvil body means carries out a partial irregular rotational movement.
Claim 3
Dependent Claim
65 words
An apparatus for cutting a throughpassing lengthwise displaceable strand of material, especially a textile yarn, as defined in claim 1, wherein said anvil body means is defined by a body of rotation having a peripheral surface forming said anvil surface, said body of rotation possessing an axis of rotation disposed in the plane of movement of saiD cutting edge portion of said cutting knife means.
Claim 4
Dependent Claim
51 words
An apparatus for cutting a throughpassing lengthwise displaceable strand of material, especially a textile yarn, as defined in claim 2, wherein said body of rotation defining said anvil body means comprises a cylinder having an axis of rotation extending substantially parallel to said cutting edge portion of said cutting knife means.
Claim 5
Dependent Claim
38 words
An apparatus for cutting a throughpassing lengthwise displaceable strand of material, especially a textile yarn, as defined in claim 1, wherein said anvil surface of said rotatably mounted anvil body means is defined by an end surface thereof.
Claim 6
Dependent Claim
76 words
An apparatus for cutting a throughpassing lengthwise displaceable strand of material, especially a textile yarn, as defined in claim 1, further including support means for supporting said cutting knife means, and means mounting said cutting knife means at said support means so as to be moveable with difficulty relative to said anvil surface for the purpose of accommodating the cutting position of the cutting edge portion of said cutting knife means relative to said anvil surface.
Claim 7
Dependent Claim
55 words
An apparatus for cutting a throughpassing lengthwise displaceable strand of material, especially a textile yarn, as defined in claim 1, wherein said anvil body means is rotatable about an axis of rotation, said cutting edge portion of said cutting knife means lying in a plane which is offset with respect to said axis of rotation.
