Abstract
A method, a cutting device and an apparatus wherein, at cusp-shaped recesses obtained by die cutting on a ribbon in order to obtain pouches with rounded corners, the ribbon is cut transversely by means of at least two strokes of a blade. A relative translation is performed, between the first stroke and the second stroke, between the cutting plane and the ribbon substantially along a feeding direction of the ribbon, so as to level with the second stroke any cutting defects of the first stroke in the region of the recess.
Claims13
A cutting method, for manufacturing pouches of flexible containers with rounded corners, comprising the steps of:
- stepwise advancing a ribbon, comprising pockets formed between layers thereof, along a substantially rectilinear feeding direction, said ribbon comprising a plurality of recesses along at least one longitudinal edge thereof that is substantially parallel to said substantially rectilinear feeding direction;
- transverse cutting from one longitudinal edge to another of said ribbon and substantially at each one of said recesses, said transverse cutting being performed by means of at least one blade, said at least one blade being movable with respect to said ribbon substantially along a cutting plane that is transverse to said ribbon and to said feeding direction;
- wherein substantially at each one of said recesses, said transverse cutting of the ribbon is performed by means of at least two strokes of said at least one blade,
- and wherein between a first stroke and a second stroke of said at least two strokes of said at least one blade a relative translation is performed between said cutting plane and said ribbon substantially along said feeding direction, wherein said second stroke removes any cutting defects of the first stroke in a region of said recess.

A cutting device for cutting ribbons for apparatuses for manufacturing pouches of flexible containers with rounded corners, the cutting device comprising:
- a feeding inlet adapted to receive, along a substantially rectilinear feeding direction, a ribbon to be cut along at least one substantially rectilinear cutting direction, said at least one cutting direction being transverse with respect to said feeding direction and forming, together with said feeding direction, a geometric plane of arrangement of the ribbon;
- at least one cutting blade adapted to cut said ribbon along said at least one cutting direction;
- a blade holder on which said at least one cutting blade is mounted, said blade holder being mounted on a support and being movable, with respect to said support and transversely with respect to said plane of arrangement, between a first position and a second position in order to perform said cut by means of said at least one blade;
- first movement means adapted to move said blade holder between said first and second positions;
- wherein said support is configured to move with a reciprocating motion substantially parallel to said plane of arrangement between a forward position and a retracted position along said feeding direction in order to allow a respective cutting stroke of said at least one blade in each one of said forward and retracted positions;
- wherein said at least one cutting blade comprises a first cutting edge and a second cutting edge along respective opposite edges of said at least one blade, said first position of the blade holder is such that the first cutting edge is directed toward said plane of arrangement, said second position of the blade holder is such that the second cutting edge is directed toward said plane of arrangement;
- wherein the cutting device comprises at least one port which can be connected to a pump and is arranged along said first cutting edge, said second cutting edge, or both.

A device for cutting ribbons for apparatuses for manufacturing pouches of flexible containers with rounded corners, the device comprising:
- a feeding inlet adapted to receive, along a substantially rectilinear feeding direction, a ribbon to be cut along at least one substantially rectilinear cutting direction, said at least one cutting direction being perpendicular with respect to said feeding direction and forming, together with said feeding direction, a geometric plane of arrangement of the ribbon;
- at least one cutting blade adapted to cut said ribbon along said at least one cutting direction by moving perpendicularly to said geometric plane of arrangement of the ribbon;
- a blade holder on which said at least one cutting blade is mounted, said blade holder being mounted on a support and being movable, with respect to said support and transversely with respect to said plane of arrangement, between a first position and a second position in order to perform said cut by means of said at least one blade;
- and
- first movement means adapted to move said blade holder between said first and second positions,
- wherein said support is configured to move with a reciprocating motion substantially parallel to said plane of arrangement between a forward position and a retracted position along said feeding direction in order to allow a respective cutting stroke of said at least one blade in each one of said forward and retracted positions,
- wherein said at least one cutting blade comprises a first cutting edge and a second cutting edge along respective opposite edges of said at least one blade, said first position of the blade holder is such that the first cutting edge is directed toward said plane of arrangement, said second position of the blade holder is such that the second cutting edge is directed toward said plane of arrangement.
