Abstract:
Modelling apparatus for producing a model or models by lamination of sheet material comprising:(a) a support platform adapted to be incrementally raised and lowered in response to a predetermined program; (b) a sheet feed mechanism for feeding cellular structure sheet material onto or over the support platform; (c) a superstructure mounted over said support platform; (d) cutting means for cutting said sheet material to a predetermined depth, said cutting means being movable along a first predetermined path in response to said predetermined program thereby to cut a shaped portion from the sheet material on the support platform; (e) adhesive applicator means mounted above said support platform for applying adhesive to said shaped portion of said sheet material and movable in a predetermined manner in accordance with said predetermined program; (f) and control means including input means for input of information concerning the desired size and shape of the model to be made and output control means for controlling the sheet feed mechanism and movement of said support platform, the cutting means and the adhesive applicator means in accordance with said predetermined program; characterised in that there is provided:said superstructure mounted over said support platform and wherein: said cutting means and said adhesive applicator means are supported on carriage means; said carriage means is mounted on said superstructure for movement in a horizontal plane above said support platform; said control means is operable to move said carriage means in said horizontal plane: (a) along said first predetermined path to enable cutting of said sheet material by said cutting means, and (b) in said predetermined manner to enable application of adhesive to said shaped portion of said sheet material by said adhesive applicator means; the superstructure carries linearly movable thereon a first carriage of said carriage means which in turn carries a second carriage of said carriage means linearly movable thereon for movement of the second carriage in two orthogonal directions (X and Y); and said second carriage carries the cutting means and adhesive applicator means.
