Abstract

A beam is formed from a rectangular strip (11) of metal having Laser cut parallel longitudinal edges by, first, bending the strip (11), using a jig arrangement, about two fold lines respectively inset from the longitudinal edges (13A, 13b) of the strip (11), such as to create two upstanding marginal flanges. Next, the so-flanged sheet is bent about a longitudinal central fold line (35) such as to create a longitudinally-folded sheet of V-form cross-section, but with in-turned flanges at the mouth of the V-form section. Finally, the V-form folded sheet is braced using either a metal strip (39) or external constraint members that embrace the V-form folded sheet at intervals therealong. The beam may serve as a trackway means for a machine tool, a tool-carrying carriage (57) having wheels rotatable about vertical axes, with the wheels (61,63) in running contact with the trackway means at surfaces adjacent to the bend positions of the flanges (33A, 33b).

Claims

AMENDED CLAIMS[received by the International Bureau on 17 December 2002 (17.12.2002); original claims 1-2 amended; remaining claims unchanged (3 pages)]
1. A method of forming a beam, being a method characterized by the steps comprising:
. bending a body of flat sheet metal (11) , having longitudinally-extensive, substantially parallel, edges (13a, 13b) , about notional parallel fold lines, respectively inset with respect to said parallel edges, such as to render said sheet metal body to a channel-form, that is to say, a body having a flat web portion (33c) with upstanding lateral flange portions (33a, 33b) ;
. bending said web portion about a longitudinal medial fold line (35) thereof in such manner as to convert said web portion from a flat to a substantially V-shaped channel part with said flange portions (33a/ 33b) projecting inwardly thereof; and, subjecting the inclined walls (37a, 37b) of said channel part to the action of bracing means (as 39) being bracing means such and so disposed as to serve to oppose any tendency of the channel part to bend under load whilst leaving the space separating the longitudinally extensive free edges of said flange portions unbridged.
2. The method as claimed in claim 1 characterized in that:
. said lateral flange portions (33a, 33b) of said channel are at equal angles with respect to the web portion (33c) of the channel. 14
3. The method as claimed in claim 1 or 2 characterized in that:
. said bracing means comprises a strip (39) of sheet metal having longitudinal edges parallel with one another, said strip being disposed within said V- shaped channel and being united with said inclined walls by welds between the strip and said walls at intervals therealong.
4. The method as claimed in claim 3 characterized in that:
. said bracing strip is united with said walls at tack welds along the edges thereof.
5. The method as claimed in claim 1 or 2 characterized in that:
. said bracing strip has longitudinally-extensive marginal flat portions (43a, 43b) at an angle such that these lie in contact with said walls, and spot welds unite said flat marginal portions with said walls at intervals along said marginal portions.
6. The method as claimed in claim 1 or 2 characterized in that: . said bracing means comprises: a multiplicity of bracket members (49) spaced apart externally along said V-shaped channel, being bracket members having opposed re-entrant portions within which said flanges and adjacent portions of said walls have a snug fit. 15
The method as claimed in any preceding claim characterized in that:
. said web portion is bent to a V-shaped channel the inclined walls of which subtend an angle the magnitude of which is such that said inclined walls and said lateral flanges make angles of equal magnitude with respect to the plane containing the opposed lines (P—P) defining the junctures of said inclined walls with said flanges.
8. The method as claimed in claim 7 characterized in that:
. the web portion is bent such that inclined walls and said flanges make angles of forty-five degrees (45 ) with respect to said plane.
9. A beam produced using the method as claimed in any of the preceding claims.
10. An apparatus which is characterized by:
. trackway means means comprising at least one beam B as claimed in claim 9, and carriage means 61 constructed arranged and adapted to co-act with said trackway means such as to be held captive thereto whilst being permitted movement, substantially solely, therealong.
