Claims25
A device for cutting a flexible material, laminated between two substrates and overhanging edges of the two substrates, the two substrates with the laminated flexible material forming a laminated glazing, the device comprising:
- a cutting tool constructed and arranged to cut an overhanging portion of the flexible material;
- a pulling tool constructed and arranged to pull only the overhanging portion of the flexible material, and
- a conveyor constructed and arranged to provide a relative movement between the laminated glazing on one hand and the cutting and pulling tools on the other hand, wherein the pulling tool is arranged upstream of the cutting tool such that, during the relative movement by the conveyor, the pulling tool pulls on at least part of the overhanging portion in a direction substantially transverse to the edges of the two substrates before the cutting tool cuts said at least part of the overhanging portion so that said at least part of the overhanging portion is in a stretched state when the cutting tool cuts said at least part of the overhanging portion.
