Vehicle Glazing Panel Cut Out

Abstract

A glazing panel cut out system for use with a cutting wire in cutting out a vehicle glazing panel cut out procedure has a dispenser unit for dispensing cutting wire and a winder unit for winding the wire, both being mounted to the glazing panel during use. The winder unit has one or more winder spools for winding the cutting wire dispensed from the dispenser. The cutting wire is paid out from the dispenser whilst mounted to the glazing panel during the cut out procedure.

1 . A glazing panel cut out system for use with a cutting wire in cutting out a vehicle glazing panel cut out procedure, the system including:
 a dispenser unit for dispensing cutting wire the dispenser having means for mounting to the glazing panel and enabling cutting wire to be paid out from the dispenser whilst mounted to the glazing panel during the cut out procedure; and;   a winder unit including;
 a mounting arrangement for mounting the winder unit on the glazing panel; 
 at least one winder spool for winding cutting wire dispensed from the dispenser. 
   
     
     
         2 . A system according to  claim 1 , wherein the winder unit includes at least one wire wrap around guide element spaced from the winder spool and/or the mounting means. 
     
     
         3 . A system according to  claim 1 , wherein the winder unit includes first and second winder spools for winding the cutting wire. 
     
     
         4 . A system according to  claim 1 , wherein the dispenser unit and the winder unit are mounted to opposed faces of the glazing panel. 
     
     
         5 . A system according to  claim 1 , wherein the wire dispenser unit includes a rotatable spool for paying out the wire. 
     
     
         6 . A system according to  claim 1 , wherein the mounting means for the dispenser unit comprises a suction mount. 
     
     
         7 . A system according to  claim 1 , wherein a brake or drag arrangement is provided to brake or hinder the paying out of the wire from the dispenser unit. 
     
     
         8 . A system according to  claim 3 , wherein the wrap around guide element comprises a guide wheel or pulley rotatably mounted with respect to the winder unit. 
     
     
         9 . A system according to  claim 1 , wherein two winder spools are arranged in side by side arrangement, a respective wire guide wheel or pulley being positioned outwardly of each respective winder spools. 
     
     
         10 . A system according to  claim 1 , wherein the winder spool includes a ratchet arrangement enabling spool rotation in one or other direction to be inhibited. 
     
     
         11 . A method of cut out of a vehicle glazing panel bonded in a frame by means of interposed bonding material, the method comprising:
 setting a wire winder unit on the windscreen, the winder unit including one or more winder spools;   setting a wire dispenser unit on the windscreen, looping the cutting wire about the periphery of the glazing panel and connecting a free end of the wire paid out from the dispenser to the winder spool of the winder unit;   operating the winder spool of the winder unit to wind the wire and thereby cut the bonding material, wherein during cutting wire is paid out from the dispenser unit to effect slip cutting of the bonding material.   
     
     
         12 . A method according to  claim 11 , wherein the dispenser unit and the winder unit are mounted on opposed surfaces of the glazing panel. 
     
     
         13 . A method according to  claim 11 , wherein following operation of the winder unit to cut out a portion of the glazing panel, a length of wire is paid out of the dispenser unit and cut to form a further free end, the further free end then being connected to a winder spool of the winder unit, which spool is then wound to effect cutting out of a further portion of the glazing panel. 
     
     
         14 . A method according to  claim 11 , wherein the wire paid out from the dispenser unit passes via a brake or drag device to inhibit paying out of the wire from the dispenser unit. 
     
     
         15 . A method according to  claim 11 , wherein the respective free ends of the wire are attached to different respective winder spools of the winder unit.
