A glazing panel removal device comprising a winder unit (1) having first and second winder spools (10, 11) for winding a cutting filament (100) and a drive, for driving the winder spools (10). The drive means includes a single or common drive input for driving both the first and second winder spools (10, 11). The drive maybe a rotary input drive, and driving the rotary input in a first rotary direction may cause winding of the filament (100) onto the first winder spool (10) and driving the rotary input in the opposite direction causes winding of the filament (100) onto the second winder spool (11).
