A method of forming a material, said method comprising or including the steps of a. presenting a formable material between opposing forming surfaces (23, 24) from whence said material is carried by and between opposing forming surfaces (23, 24) as said opposing forming surfaces (23, 24) advance in an advancing direction, b. pressurising, as said opposing forming surfaces (23, 24) advance, said material between said opposing forming surfaces (23, 24) in a reduced space between said opposing forming surfaces (23, 24) defining at least in part a pressure forming zone, said reduced space between said opposing forming surfaces (23, 24) being maintained at least substantially constant until such time as the form of at least one of said opposing forming surfaces (23, 24) is profiled into said material and is retainable thereon, and c. releasing the now profiled material from between said opposing forming surfaces (23, 24), as the space increases between said opposing forming surfaces (23, 24) as the opposing forming surfaces (23, 24) advance, wherein each of said opposing forming surfaces (23, 24) is provided by one or more forming tool or tools of a set of forming tools (3,4) being advanced about its own guiding circuit, wherein a first set of forming tools is moved about a first circuit about a first forming tool set guide or guides and a second set of forming tools is moved about a second circuit about a second forming tool set guide or guides, wherein each of said forming tools is advanced at least in part by driving action on said forming tools by a driving means through said pressure forming zone and wherein as said forming tools present in a lead-in zone to the pressure forming zone to pressurise said material there is no gap between adjacent forming tools of each set of forming tools (3, 4) at least where they contact said forming material, and the relative movement between adjacent tools of at least one of said first and second sets of forming tools (3, 4) over said lead-in zone to pressurise is only towards the forming tools of said other opposing surface (23, 24), wherein in said pressure forming zone where said step (b) pressurising takes place, one series of forming tools present forming surfaces (23, 24) downwardly whilst in an underlying series of forming tools present forming surfaces (23, 24) upwardly, and wherein in said pressure forming zone, where said step (b) pressurising takes place, each of said forming tools is supported on one or more guide tracks of said guiding circuit acting on two axes of each said forming tool on its flanks transverse to said advancing direction, thereby to present reproducibly said forming tool, insofar as orientation is concerned, in said pressure forming zone, and wherein said forming tool is a composite of at least one carrier tool that runs in or on said one or more guide tracks and at least one surface tool to provide at least one of said opposing surfaces (23, 24), said surface tool mounted to or from said carrier tool to be carried thereby, and wherein at least one of said sets of forming tools and its guiding circuit is moveable relative to the other set of forming tools and its guiding circuit so as to effect opening or closing of said forming tools and opposing forming surfaces of said pressure forming zone. a. presenting a formable material between opposing forming surfaces (23, 24) from whence said material is carried by and between opposing forming surfaces (23, 24) as said opposing forming surfaces (23, 24) advance in an advancing direction, b. pressurising, as said opposing forming surfaces (23, 24) advance, said material between said opposing forming surfaces (23, 24) in a reduced space between said opposing forming surfaces (23, 24) defining at least in part a pressure forming zone, said reduced space between said opposing forming surfaces (23, 24) being maintained at least substantially constant until such time as the form of at least one of said opposing forming surfaces (23, 24) is profiled into said material and is retainable thereon, and c. releasing the now profiled material from between said opposing forming surfaces (23, 24), as the space increases between said opposing forming surfaces (23, 24) as the opposing forming surfaces (23, 24) advance,
