Title: Foam section cutter - has laser beam with controlled energy supply and cutting speed to cut and seal edges simultaneously
Inventor: MERKT REINER
IPC: B23K26/24
Filed: 1990-06-09
Abstract: To cut shaped foam material sections, where the material is covered on both sides and the foam is compressed between the sections to the thickness of the covering layers, a laser beam is moved along the cutting line between sections which, simultaneously, severs the sections and seals the cut edges. The energy delivered by the laser beam, to melt the layers of the foam sections, is pref. carried over to the cut edges, and the ratio of beam energy to cutting speed is selected to ensure that the cut edges of the layers round the foam fuse together. The alignment of the laser beam is generally orthogonal to the plane of the layer to be cut over the foam. ADVANTAGE - The material can be cut and sealed rapidly and effectively, without complex appts., in a process which can be automated.
