Abstract
Abstract Method of making marker assemblies comprising an elongate denticule whose flat, pendent tines bear in snug and slidable relation heat recovered sleeves which conform to the flattened configuration of the tines. After positioning generally tubular heat recoverable sleeves over the pendent tines and recovery of the same, printed information may be imparted to the tine-borne sleeves, which thereafter may be removed from the denticular support and employed as identifying markers for electrical wire and the like.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
101 words
A method of forming flattened sleeves having printed indicia thereon, comprising the steps of disposing over individual ones of a plurality of flat tines spaced one apart from another and transversely pendant from at least one side of an elongate spine individual ones of a plurality of tubular plastic sleeves heat shrinkable to a lesser diametral dimension, and heating said sleeves about said tines to bring the former into snug and slidable relation conforming to the flat configuration of said tines and printing indicia on flat portions of said sleeves while said sleeves are conformed to flattened portions of said tines.
Claim 2
Independent Claim
101 words
A method of forming flattened sleeves having printed indicia thereon, comprising the steps of disposing over individual ones of a plurality of flat tines spaced one apart from another and transversely pendant from at least one side of an elongate spine individual ones of a plurality of tubular plastic sleeves heat shrinkable to a lesser diametral dimension, and heating said sleeves about said tines to bring the former into snug and slidable relation conforming to the flat configuration of said tines and printing indicia on flat portions of said sleeves while said sleeves are conformed to flattened portions of said tines.
Claim 3
Dependent Claim
18 words
A method according to claim 1 wherein a release agent is disposed between said tines and said sleeves.
Claim 4
Dependent Claim
24 words
A method according to claim 2 wherein prior to disposition of said sleeves over said tines, the tines are coated with a release agent.
Claim 5
Dependent Claim
52 words
A method according to claim 1 wherein the heat absorptivity of the characters making up said printed information is greater than that of unprinted portions of said surface, and which comprises the additional step of exposing printed sleeves carried by said tines to radiant heat sufficient to render said information essentially indelible.
Claim 6
Dependent Claim
19 words
A method according to claim 4 wherein said spine is heat-shielded during exposure of said sleeves to said heat.
