Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
201 words
In a device for cutting material, particularly textiles and the like, comprising a support for the material, a loop of cutting wire, part of said loop of cutting wire being substantially perpendicular to the material and movable with respect thereto for following a particular pattern, said wire being guided on guide rOlls disposed on opposite sides of the material, one of the guide rolls being driven for causing linear movement of said part of said cutting wire for causing cutting of said material, comprising the improvement wherein the wire has a cross section which is substantially equilaterally triangular, and guide means coacting with said part of said loop of wire for permitting said part to be angularly displaced about its longitudinally extending centerline, said guide means including a guide member mounted for angular movement substantially about said centerline and a plurality of guide rollers rotatably supported on the guide member and disposed for rolling and guiding engagement with said part of said loop of wire, and means interconnected to said guide member for permitting same to be angularly displaced about said centerline for causing a corresponding angular displacement of said part of said loop of wire about its longitudinally extending centerline.
Claim 2
Dependent Claim
201 words
In a device for cutting material, particularly textiles and the like, comprising a support for the material, a loop of cutting wire, part of said loop of cutting wire being substantially perpendicular to the material and movable with respect thereto for following a particular pattern, said wire being guided on guide rOlls disposed on opposite sides of the material, one of the guide rolls being driven for causing linear movement of said part of said cutting wire for causing cutting of said material, comprising the improvement wherein the wire has a cross section which is substantially equilaterally triangular, and guide means coacting with said part of said loop of wire for permitting said part to be angularly displaced about its longitudinally extending centerline, said guide means including a guide member mounted for angular movement substantially about said centerline and a plurality of guide rollers rotatably supported on the guide member and disposed for rolling and guiding engagement with said part of said loop of wire, and means interconnected to said guide member for permitting same to be angularly displaced about said centerline for causing a corresponding angular displacement of said part of said loop of wire about its longitudinally extending centerline.
Claim 3
Dependent Claim
75 words
A device according to claim 1, wherein there are three said guide rollers, each having a peripheral face disposed in rolling engagement with one of the sides of said wire, each of said three guide rollers being mounted on said guide member for rotation about an axis substantially perpendicular to the centerline of said part of said loop of wire, the rotational axes of adjacent guide rollers defining an included angle of approximately 60* therebetween.
Claim 4
Dependent Claim
75 words
A device according to claim 2 wherein said guide member is rotatably supported on a fixed housing for enabling said guide member to be angularly displaced about said centerline, holder means associated with each of said guide rollers for rotatably supporting same, and resilient means coacting between said guide member and each of said holder means for resiliently urging each of said guide rollers into rolling engagement with a respective side surface of said wire.
Claim 5
Dependent Claim
24 words
A device according to claim 3, wherein said resilient means comprise resilient pins connected between said guide member and each of said holder means.
Claim 6
Dependent Claim
47 words
A device according to claim 3, wherein said means for causing angular movement of said guide member includes drive means for causing angular oscillation of said guide member, which in turn causes angular oscillation of said part of said loop of wire about said longitudinal centerline thereof.
Claim 7
Dependent Claim
40 words
A device according to claim 5, wherein said drive means includes a rotatable eccentric and linkage means connected between said eccentric and said guide member for causing angular oscillation of said guide member in response to rotation of said eccentric.
Claim 8
Dependent Claim
112 words
A device according to claim 1, wherein said means for permitting angular movement of said guide member includes drive means interconnected to said guide member for causing said part of said loop of wire to be angularly displaceable through a maximum permissible angle of approximately 60* in either direction from a neutral position for causing one of the three cutting edges of the wire to always be directed substantially tangential to the cutting path and for causing one of the other cutting edges to be directed substantially tangential to the cutting path when the path direction deviates more than 60* from the normal neutral or rest position of said one cutting edge.
Claim 9
Dependent Claim
42 words
A device according to claim 1, wherein said guide means is angularly displaceable through a maximum permissible angle of approximately 60* in opposite direction from a neutral position for enabling the three cutting edges of said wire to generate a cylindrical profile.
