Abstract

A plurality of individual, pre-formed cutting tips attached to one another in an adjoining series to form an elongate stick of tips are utilized for sequentially attaching the tips 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.

Dependent claims

A method of manufacturing cutting blades of the type having a series of spaced teeth formed therein and a respective pre-formed cutting tip attached to each tooth, each of said pre-formed cutting tips on said blades having a pre-formed contact surface attached to a respective tooth and a pre-formed cutting edge separate from said contact surface oriented in an operative cutting position, said method of manufacturing said blades comprising:

a. prior to attaching said pre-formed cutting tips to said teeth of said blades, holding said respective pre-formed cutting tips in attached relation to one another in an adjoining series forming an elongate strip of said pre-formed cutting tips;
b. positioning the pre-formed contact surface of one of said cutting tips located on one end of said strip in close proximity with a tooth of a respective blade;
c. joining the pre-formed contact surface of said end cutting tip operatively to said tooth such that the pre-formed cutting edge of said end cutting tip is in said operative cutting position;
and
d. detaching said end cutting tip from the remainder of said elongate strip of pre-formed cutting tips.
