Abstract
The invention discloses a device for cutting through an adhesive bead of a vehicle pane, in particular a windshield, having a motor-driven winding-up device that comprises a coil for winding up a cutting wire in a working direction for cutting through the adhesive bead, the winding-up device being provided with a strain relief for the cutting wire which allows the cutting wire to be withdrawn from the winding-up device in a sense opposite to the working direction.
Claims20
A device for cutting through an adhesive bead of a vehicle pane, said device comprising winding-up device, wherein said winding-up device comprises:
- a coil for winding up a cutting means in a working direction for cutting through said adhesive bead;
- a motor drive coupled to said coil for rotating said coil;
- a strain relief coupled to said motor drive so as to allow relief of said cutting means from said coil in a relief direction in a sense opposite to said working direction;
- and
- a control having a switch for switching said drive between an on-state and an off-state;
- wherein said control is configured for rotating said drive in said working direction when said switch is in said on-state;
- and
- wherein said control is configured for rotating said drive in said relief direction for a preset time before stopping said drive upon switching into said off-state
A device for cutting through an adhesive bead of a vehicle pane, said device comprising winding-up device, wherein said winding-up device comprises:
- a coil for winding up a cutting means in a working direction for cutting through said adhesive bead;
- a motor drive coupled to said coil for rotating said coil;
- and
- a strain relief coupled to said motor drive so as to allow relief of said cutting means from said coil in a relief direction in a sense opposite to said working direction.
A method of cutting through an adhesive bead of a pane comprising the steps of:
- placing a cutting means around said adhesive bead from the outside;
- fixing a first end of said cutting means on an outside of said pane;
- guiding a second end of said cutting means through said adhesive bead and fixing it at an inner side of said pane on a motor-driven winding-up device;
- driving said winding-up device for winding up said cutting means for cutting through said adhesive bead, while guiding by means of a support said winding-up device along a frame to which said pane is attached along a frame;
- interrupting said winding-up step and tearing said cutting means out of said winding-up device for a certain amount;
- re-positioning said winding-up device with said support on said frame;
- and
- resuming the cutting step by driving the winding-up device.
