Abstract
Abstract A plurality of individual, pre-formed cutting tips attached to one another in an adjoining series to form an elongate stick of tips for sequential attachment to the teeth or cutting portions of cutting tools. Each tip in the stick has a commonly oriented contact surface for attachment to the cutting tool, and a separate pre-formed cutting edge that forms the cutting edge of the tool once the tip has been attached. Attachment of a tip to a cutting tool is accomplished by positioning the contact surface of the lead tip in a stick proximate the tool, and severing the connection between the tip and the remainder of the stick. The tips forming the stick are preferably attached to one another by a meltable adhesive spread over their respective contact surfaces, such adhesive having a melting point lower than that of the tips. The respective tips in the stick are operatively connected to separate teeth or tools by the same adhesive.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
225 words
A cutting tip stick comprising: a plurality of individual elongate cutting tips pre-formed for separate attachment to the teeth of a cutting blade; each said elongate cutting tip having respective first and second longitudinally opposite ends, means defining a pre-formed contact surface extending along the majority of the length thereof for mating with a tooth of a cutting blade, and a pre-formed cutting edge separate from said contact surface formed at said first end thereof; said cutting tips being attached to one another by adhesive means in an adjoining series forming an elongate strip of said tips, said adhesive means being attached to the contact surface of each said cutting tip in an amount on each contact surface effective for bonding said contact surface operatively to a tooth of a cutting blade, said respective first end of each said tip being positioned adjacent the second end of a next adjoining one of said tips in said series in substantially end-to-end relation such that said majority of the length of each tip is free of abutment with any adjoining tips in said series, so as to permit each said respective contact surface along the length of a tip to be placed in operative attaching position against a respective tooth of a cutting blade while said tip remains attached to a next adjoining tip in said series.
Claim 2
Dependent Claim
225 words
A cutting tip stick comprising: a plurality of individual elongate cutting tips pre-formed for separate attachment to the teeth of a cutting blade; each said elongate cutting tip having respective first and second longitudinally opposite ends, means defining a pre-formed contact surface extending along the majority of the length thereof for mating with a tooth of a cutting blade, and a pre-formed cutting edge separate from said contact surface formed at said first end thereof; said cutting tips being attached to one another by adhesive means in an adjoining series forming an elongate strip of said tips, said adhesive means being attached to the contact surface of each said cutting tip in an amount on each contact surface effective for bonding said contact surface operatively to a tooth of a cutting blade, said respective first end of each said tip being positioned adjacent the second end of a next adjoining one of said tips in said series in substantially end-to-end relation such that said majority of the length of each tip is free of abutment with any adjoining tips in said series, so as to permit each said respective contact surface along the length of a tip to be placed in operative attaching position against a respective tooth of a cutting blade while said tip remains attached to a next adjoining tip in said series.
Claim 3
Dependent Claim
47 words
The cutting tip stick of claim 1 wherein said cutting tips are oriented end to end in an inclined position with respect to the length direction of said elongate strip so that their respective cutting edges form a ratchet-like surface along the length of said elongate strip.
Claim 4
Dependent Claim
26 words
The cutting tip stick of claim 1 wherein said adhesive means is a meltable adhesive having a melting point lower than that of said cutting tips.
Claim 5
Dependent Claim
48 words
The cutting tip stick of claim 1 wherein said adhesive means is attached to the contact surfaces of said cutting tips in a series of globules, each said globule being attached to a respective contact surface of a cutting tip and to a portion of an adjoining tip.
Claim 6
Dependent Claim
138 words
A cutting tip stick comprising: a plurality of individual cutting tips pre-formed for attachment to the teeth of cutting blades; each said cutting tip having means defining a pre-formed contact surface for mating with a tooth of a cutting blade and a pre-formed cutting edge separate from said contact surface, said cutting tips being attached to one another in an adjoining series forming an elongate strip of said tips; and an adhesive detachably connecting said individual cutting tips together in said adjoining series, said adhesive comprising multiple adhesive globule means each attached to a respective contact surface of one of said cutting tips and to a portion of an adjoining tip in said series, each said globule means having an amount of adhesive effective for operatively bonding a respective cutting tip to a tooth of a cutting blade.
Claim 7
Dependent Claim
138 words
A cutting tip stick comprising: a plurality of individual cutting tips pre-formed for attachment to the teeth of cutting blades; each said cutting tip having means defining a pre-formed contact surface for mating with a tooth of a cutting blade and a pre-formed cutting edge separate from said contact surface, said cutting tips being attached to one another in an adjoining series forming an elongate strip of said tips; and an adhesive detachably connecting said individual cutting tips together in said adjoining series, said adhesive comprising multiple adhesive globule means each attached to a respective contact surface of one of said cutting tips and to a portion of an adjoining tip in said series, each said globule means having an amount of adhesive effective for operatively bonding a respective cutting tip to a tooth of a cutting blade.
Claim 8
Dependent Claim
61 words
The cutting tip stick of claim 5 wherein each said adhesive globule means comprises meltable adhesive means for operatively bonding a respective cutting tip to a tooth of a cutting blade by the melting and subsequent hardening of said adhesive means and for releasing said respective tip from said adjoining tip automatically in response to said melting of said adhesive means.
