Abstract
Abstract A tool, particularly adapted for use with a computer controlled robot includes an adhesive application device for depositing a quantity of liquid adhesive to a work piece, a transport roller for engaging the elongated material with the deposited adhesive on the work piece and about which the elongated material may be fed, and a separation means for severing a predetermined applied length of the elongated material from the supply of such material. The position of a pinch roller relative to the elongated material and transport roller is remotely controlled to provide holding of the elongated material during adhesive application, tacking, and cutting, and feeding of the material between tacking and cutting.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
In a process for applying an elongated material from a supply of such material to a work piece, the improvement comprising: threading said elongated material around a transport roller for travel thereabout; depositing a limited area of liquid adhesive to said work piece; engaging said elongated material with a portion of said limited area of said liquid adhesive by movement of said transport roller into a first position whereby said elongated material is compressed between said roller and said work piece; feeding said elongated material beyond said limited area by providing relative movement of said tool and said work piece, with said transport roller in a second position whereby said elongated material is not compressed between said roller and said work piece; and separating a length of said elongated material from said supply of said elongated material.
Claim 2
Dependent Claim
137 words
In a process for applying an elongated material from a supply of such material to a work piece, the improvement comprising: threading said elongated material around a transport roller for travel thereabout; depositing a limited area of liquid adhesive to said work piece; engaging said elongated material with a portion of said limited area of said liquid adhesive by movement of said transport roller into a first position whereby said elongated material is compressed between said roller and said work piece; feeding said elongated material beyond said limited area by providing relative movement of said tool and said work piece, with said transport roller in a second position whereby said elongated material is not compressed between said roller and said work piece; and separating a length of said elongated material from said supply of said elongated material.
Claim 3
Dependent Claim
155 words
In a tool for applying an elongated material from a supply of such material to a work piece, the improvement comprising: a transport roller about which said elongated material travels between said roller and said work piece; means for moving said transport roller into a first position whereby said elongated material is compressed between said roller and said work piece and into a second position whereby said elongated material is not compressed between said roller and said work piece; adhesive application means for depositing a limited area of liquid adhesive to said work piece; means for engaging said elongated material with a portion of said limited area of liquid adhesive by movement of said transport roller into said first position; means for feeding said elongated material beyond said limited area with said transport roller in said second position; and means for separating a length of said elongated material from said supply of said elongated material.
Claim 4
Dependent Claim
155 words
In a tool for applying an elongated material from a supply of such material to a work piece, the improvement comprising: a transport roller about which said elongated material travels between said roller and said work piece; means for moving said transport roller into a first position whereby said elongated material is compressed between said roller and said work piece and into a second position whereby said elongated material is not compressed between said roller and said work piece; adhesive application means for depositing a limited area of liquid adhesive to said work piece; means for engaging said elongated material with a portion of said limited area of liquid adhesive by movement of said transport roller into said first position; means for feeding said elongated material beyond said limited area with said transport roller in said second position; and means for separating a length of said elongated material from said supply of said elongated material.
Claim 5
Dependent Claim
74 words
In the tool of claim 2 wherein said means for separating further comprises a pinch roller operable to compress said elongated material against said transport roller to inhibit further feeding of said elongated material about said transport roller; and severing means for disconnecting a length of said elongated material from said supply of such material, whereby an end of said supply of elongated material is retained between said pinch roller and said transport roller.
Claim 6
Dependent Claim
20 words
In the tool of claim 3 wherein said pinch roller means is moved by at least one fluid operated cylinder.
Claim 7
Dependent Claim
21 words
In the tool of claim 3 wherein said adhesive application means further comprises an adhesive application reservoir attached to said tool.
Claim 8
Dependent Claim
41 words
In the tool of claim 5 wherein said adhesive application reservoir means further comprises means associated with said reservoir for dispensing said adhesive onto said work piece when a tip of said adhesive application reservoir is applied to said work piece.
Claim 9
Dependent Claim
23 words
In the tool of claim 6 further comprising means for moving said tool with said associated reservoir into contact with said work piece.
Claim 10
Dependent Claim
28 words
In the tool of claim 7 wherein said severing means further comprises heating means for melting said length of elongated material apart from said supply of such material.
