Abrégé

The present invention relates to a device for working, e.g. cutting, milling, planing etc., of a length of timber or lengths of timber (24) and similar materials, such as battens or studs, frame sections for roof trusses of optional cross section, e.g. rectangular, a plurality of conveyors (13, 14, 15, 16) being disposed for the displacement of the length(s) of timber (24) substantially in the longitudinal direction of the conveyors (13, 14, 15, 16) and transversely of the longitudinal direction of the length(s) of timber (24), that at least the convey or(s) (13, 16) located most proximal the end(s) of the length(s) of timber is/are switchable transversely of the feeding direction and thereby in the longitudinal direction of the length(s) of timber (24) in a direction to and from the end(s) of the length(s) of timber (24), and that a number of working assemblies (17, 18) with a number of tool holders (19, 20, 21) each for its or their working tool (19A, 2OA, 39, 40), e.g. a cutting saw blade, shank-end mill, cutter, etc., are displaceable in relation to the length(s) of timber (24) to a working position.

Abrégé

The present invention relates to a device for connecting a framework (6) of lengths of timber (8-11), e.g. roof trusses, comprising a number of upper (8, 9) and lower (10) frame sections, as well as a number of diagonals or struts (10), etc., at least one press tool (28-31) being disposed to fixedly press at least one nail plate (38) over joints between the lengths of timber (8, 11), and the press tool(s) (28-31) is/are disposed in a portal (3) with a number of upper beams (22, 23) and a number of lower beams (24, 25) on which the press tool(s) (28-31) is/are adjustable reciprocally across the framework (6) between a position (Fig. 11) in which the press tool (28-31) collects a pair of nail plates (38), and a position over a joint for fixedly pressing one of the nail plates on the upper side and the other on the under side of the joint.
