Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 121 words
A trim strip having a finished end made by: providing a trim strip; cutting an end portion of said trim strip in an axial direction using an end die cutter; cutting said end portion of said trim strip in a transverse direction to form a least one projecting finger using a transverse die cutter; placing said projecting finger of said end portion of said trim strip into an injection molding die having an internal cavity and clamping said trim strip end portion into said injection molding die; injecting thermoplastic material within said cavity of said die such that said material contacts and bonds to said finger and forms an end cap thereover; and withdrawing the finished trim strip from said die.
Claim 2
Dependent Claim 121 words
A trim strip having a finished end made by: providing a trim strip; cutting an end portion of said trim strip in an axial direction using an end die cutter; cutting said end portion of said trim strip in a transverse direction to form a least one projecting finger using a transverse die cutter; placing said projecting finger of said end portion of said trim strip into an injection molding die having an internal cavity and clamping said trim strip end portion into said injection molding die; injecting thermoplastic material within said cavity of said die such that said material contacts and bonds to said finger and forms an end cap thereover; and withdrawing the finished trim strip from said die.
Claim 3
Dependent Claim 19 words
A trim strip according to claim 1 wherein said end die cutter forms the shape of an inverted "U".
Claim 4
Dependent Claim 15 words
A trim strip according to claim 1 wherein a pair of protruding fingers are formed.
Claim 5
Dependent Claim 33 words
A trim strip according to claim 3 wherein said trim strip further comprises adhesive means in the form of a strip attached to the bottom surface of said trim strip and said fingers.
Claim 6
Dependent Claim 45 words
A trim strip according to claim 3 wherein said transverse die cutter includes an end cutter member with a center section which cuts completely through the sections of said trim strip between said fingers and a pair of sections which cut partially into said fingers.
Claim 7
Dependent Claim 31 words
A trim strip according to claim 5 wherein said transverse die cutter further comprises a pair of fingers forming members which cut completely through said trim strip thereby forming said fingers.
Claim 8
Dependent Claim 22 words
A trim strip according to claim 6 wherein said transverse die cutter fingers forming members are connected to said end cutter member.
Claim 9
Dependent Claim 67 words
A trim strip according to claim 5 wherein said transverse cutter end cutter member produces a cut along more than one plane such that said region between said fingers extends longitudinally beyond the portion of said transverse cut which extends into said finger and said cavity is shaped such that said region between said fingers becomes completely encased when said thermoplastic material is injected into said cavity.
Claim 10
Dependent Claim 116 words
A process for finishing the end of a trim strip comprising the steps of: providing a trim strip; cutting an end portion of said trim strip in an axial direction; cutting said end portion of said trim strip in a transverse direction to form at least one projecting finger; placing said projecting finger of said end portion of said trim strip into an injection molding die having an internal cavity and clamping said trim strip end portion in said injection molding die; injecting thermoplastic material within said cavity of said die such that said material contacts and bonds to said finger and forms an end cap thereover; and withdrawing the finished trim strip from said die.
Claim 11
Dependent Claim 116 words
A process for finishing the end of a trim strip comprising the steps of: providing a trim strip; cutting an end portion of said trim strip in an axial direction; cutting said end portion of said trim strip in a transverse direction to form at least one projecting finger; placing said projecting finger of said end portion of said trim strip into an injection molding die having an internal cavity and clamping said trim strip end portion in said injection molding die; injecting thermoplastic material within said cavity of said die such that said material contacts and bonds to said finger and forms an end cap thereover; and withdrawing the finished trim strip from said die.
Claim 12
Dependent Claim 15 words
The process according to claim 9 wherein said cutting forms a pair of protruding fingers.
Claim 13
Dependent Claim 147 words
A process for finishing the end of a trim strip comprising the steps of: providing a trim strip having adhesive means in the form of a strip attached to the bottom surface of said trim strip; cutting an end portion of said trim strip in an axial direction; cutting said end portion of said trim strip in a transverse direction to form at least one projecting finger, said finger having adhesive means attached to the bottom surface of said finger; placing said projecting finger of said end portion of said trim strip into an injection molding die having an internal cavity and clamping said trim strip end portion in said injection molding die; injecting thermoplastic material within said cavity of said die such that said material contacts and bonds to said finger and forms an end cap thereover; and withdrawing the finished trim strip from said die.
Claim 14
Dependent Claim 147 words
A process for finishing the end of a trim strip comprising the steps of: providing a trim strip having adhesive means in the form of a strip attached to the bottom surface of said trim strip; cutting an end portion of said trim strip in an axial direction; cutting said end portion of said trim strip in a transverse direction to form at least one projecting finger, said finger having adhesive means attached to the bottom surface of said finger; placing said projecting finger of said end portion of said trim strip into an injection molding die having an internal cavity and clamping said trim strip end portion in said injection molding die; injecting thermoplastic material within said cavity of said die such that said material contacts and bonds to said finger and forms an end cap thereover; and withdrawing the finished trim strip from said die.
Claim 15
Dependent Claim 20 words
The process according to claim 9 wherein said axial cutting forms a cut in the shape of an inverted "U".
Claim 16
Dependent Claim 27 words
The process according to claim 10 wherein said transverse cutting cuts completely through said trim strip in the region between said fingers and partially through said fingers.
Claim 17
Dependent Claim 63 words
The process according to claim 12 wherein said transverse cutting produces a cut along more than one plane such that said region between said fingers extends longitudinally beyond the portion of said transverse cut which extends into said finger and said cavity is shaped such that said region between said fingers becomes completely encased when said thermoplastic material is injected into said cavity.
