Abstract
A cutting apparatus for cutting an item supported by a surface, comprising a knife (1) comprising a blade (2), a blade support means (3), and an alignment guide (4), having an arm (7) pivotally attached to the knife and a surface contacting means (8) extending in a direction substantially perpendicular to the longitudinal plane of the knife and adapted to contact the surface in front of the blade, in the cutting direction so that, in use, the alignment guide can move with the blade, as the blade cuts into an item whereby if the knife tilts or tends to tilt, this is resisted by virtue of the alignment guide or, if the resistance is overcome, is reduced by raising of one or other lateral edges of the surface contacting means.
Claims15
A cutting apparatus for cutting an item supported by a surface, comprising an alignment guide, and a bow knife having a blade and a blade support means, the alignment guide having an arm pivotally attached to the bow knife and a surface contacting means extending in a direction substantially perpendicular to a longitudinal axis of the blade and adapted to rotate so that the surface contacting means contacts the surface in front of a distal end of the bow knife, in a cutting direction thereof so that, in use as the blade cuts into the item, the surface contacting means contacts the surface in front of the distal end of the bow knife and moves along the surface forwardly and backwardly as the blade cuts into the item, the surface contacting means having parts, at each lateral edge thereof, which contact the surface, whereby, if the bow knife tilts or tends to tilt, this is resisted by virtue of the alignment guide and, if the resistance is overcome, causes raising of one or other of the lateral edges of the surface contacting means from the surface.
