Abstract
A cutting apparatus is disclosed for separating, intermittently, receipts or tickets from a continuous strip of material, in which the strip is cut by a stationary blade when the user tensions the strip by pulling an end thereof, in which the cut margin of the strip is disengaged from the blade by virtue of an elastically movable element that has a non cutting edge extending in length next to the entire length of a cutting edge of the blade, and in which the strip tensioned during the cut pushes the non cutting edge in a recessing position with respect to the cutting edge and after cutting the non cutting edge returns elastically to a protruding position beyond the cutting edge.
Claims12
A cutting apparatus, comprising:
- a housing having an outlet from which a user can receive a strip of material;
- a supply path that is at least partially arranged within said housing along which the strip advances to said outlet;
- a stationary blade for cutting the strip along said path upstream of said outlet, said stationary blade including a flat side and a cutting edge extending upwardly from said flat side in an upturned V shape and transversely to an advancing direction of the strip;
- a supply device for supplying the strip along said supply path until an end thereof exits said outlet, cutting of the strip being caused by the user who tensions the strip across said cutting edge by pulling an end of the strip exiting said outlet;
- at least one unitary movable element including a fixed base connected with said stationary blade, an elastic device, and a stiff body supported by said elastic device, said stiff body having a flat side that is parallel to and abuts against said flat side of said stationary blade and terminating in an upper scraping edge that extends adjacently to and alongside said cutting edge in a transverse direction relative to the advancing direction of the strip, said scraping edge extending with an upturned V shape lying in said transverse direction, said scraping edge including a maximum protrusion zone corresponding with an apex of said upturned V shape that protrudes further than other zones of said scraping edge in said transverse direction, said stiff body adopting a protruding position wherein at least said maximum protrusion zone of said scraping edge protrudes beyond said cutting edge, and a recessed position wherein at least said maximum protrusion zone of said scraping edge is recessed and/or flush relative to said cutting edge;
- wherein an angle of said upturned V shape of said scraping edge is greater than an angle of said upturned V shape of said cutting edge;
- and
- wherein said movable element is pushed by the strip from said protruding position to said recessed position when the strip is tensioned by the user during cutting, said movable element returning elastically to said protruding position after the strip is cut to ensure that a margin of the strip that has just been cut is disengaged from said cutting edge by said scraping edge.
