Abstract

A machine for the assembly of frames, e.g. of timber, comprises a first static assembly (6), and a second assembly (8) mounted for longitudinal movement relative to the first assembly (6). The static assembly (6) comprises two adjustable side assemblies (16), and supporting assemblies, comprising support members (20, 22) providing parallel spaced supporting surfaces (23) on which elongate frame members (26) may be positioned. The moving assembly (8) carries clamping devices (60) each of which provides a datum surface, and an air cylinder to move the datum surface between operative and retracted positions, and a power operated clamp member to urge a transverse component (120) of the frame into engagement with the two datum surfaces. In the use of the machine, with the moving assembly (8) at a start position, parallel elongate frame members (26) are placed on the supporting surfaces (23), and a transverse frame member (120) is placed between the members (26), and the clamping devices (60) are operated to clamp the member (120) at a desired position, said clamping devices (60) operating from beneath the plane containing the longitudinal members (26) and the transverse member (120).
