Title:
DEVICE FOR ASSEMBLING FRAMES AND FRAME MOULDINGS AND MACHINE FOR CUTTING MITRE JOINTS FOR IMPLEMENTATION OF SAID DEVICE
Document Type and Number:
WIPO Patent Application WO1990009505
Kind Code:
A3
Abstract:
A device is disclosed for assembling frames and moulding frames, comprising a monolithic assembly piece (31) forming a double tenon and having the form of two identical circular truncated cones of a height substantially equal to the thickness of the workpieces (32, 33) to be assembled. Said assembly piece is fitted into blind bores (34, 35) of corresponding shape having on the edge junction surfaces of the workpieces to be assembled. It is intended to assembling, with or without bonding, joinery pieces of wood or other materials, such as mitered moulding frames. The mitering machine for implementing the assembly device (31) comprises a sealed casing (1) equipped with two circular saw blades (4, 5) perpendicular to each other and driven with a single electric motor. The casing is mobile vertically with respect to a working surface (3) equipped with fixing means (15, 16) for the workpiece to be cut. Two conical milling tools (28) situated under the working surface provide simultaneously the bores (34, 35) of the workpieces to be assembled.
