Abstract
An apparatus for cutting a material having prevalently two-dimensional extension into appropriately shaped portions, in particular for cutting a fabric or the like into shaped portions for the manufacture of clothing items or other items, comprising a support frame (12), means (22) for supporting said material (16), means for supporting cutting means (20). Said cutting means (20) are movable relative to said material (16) according to trajectories suited for effecting longitudinal, transverse, or otherwise oriented cuts into said material (16).
Claims89
An apparatus for cutting a material into appropriately shaped portions, comprising:
- a support frame;
- means for supporting said material connected to the support frame;
- rotatable means for cutting said material, said cutting means and said material being movable relative to each other according to suitable trajectories for the execution of cuts in said material;
- and
- means for holding the material still, said means for holding the material still comprise rollers that are rotatable and are movable across said means for supporting the material without rotation while the rollers are pressing the material against said means for supporting the material;
- wherein said means for supporting said material comprise a rigid surface that coacts with said cutting means, so that said cutting means cuts in compression, and
- wherein said means for supporting said material comprise a support plane made of electrically charged glass having appropriate hardness and defining sliding means for the material to be cut.
