Abstract
An apparatus suitable to perform the transverse cutting of various materials, especially, but not exclusively, in the form of ribbons, such as, for instance, aluminium films, paper, fiberglass, plastic films and the like comprises two circular blades, slightly spaced from one another, each blade being suitable to engage with the relevant circular counter-blades; such blades and counterblades being supported by a carriage travelling on a beam and whose traverse is caused by mechanisms, which are also connected to the carriage. These blades, counterblades, carriage and beam are placed transversally and orthogonally with respect to the feed table of the material to be cut.
Claims9
An apparatus for transversely cutting in the form of ribbons a material (72) including aluminum fibers, paper, fiberglass, and plastic fibers, said material being fed along a first direction, said apparatus comprising a pair of circular blades (14) carried on supports (50) therefor, a pair of circular counterblades (16), a carriage (20) supporting said supports (50) and said counterblades, means for causing said carriage to traverse along a beam (32) in a direction transverse to said first direction of the material to be cut, said means for causing said carriage to traverse being also adapted to move said counterblades (16), said carriage (20) consisting of a first rectangular plate (22), a second "L"-shaped plate (24) connected to said first plate (22), said first plate (22) supporting said means for causing said carriage (20) to traverse along said beam and supporting said pair of circular counterblades (16), and said second plate (24) supporting said supports (50) and said pair of circular blades (14), said second plate (24) having a horizontal side (24') and a vertical side (24"), said vertical (24") having an upper end, said said horizontal side (24') of said second plate being connected to said first plate (22), said vertical side (24") of said second plate supporting said supports (50) of said circular blades (14), said supports (50) being inserted in a way (52) integral with the upper end of said vertical side (24" ) of said second plate, and wherein said circular blades (14) have an X--X horizontal axis of rotation, said counterblades (16) have a horizontal axis of rotation Y--Y, said X--X axis being parallel to said Y--Y axis and said beam (32) being disposed transverse to said X--X and Y--Y axes, wherein each circular counterblade (16) has an annular groove (60) and each of the circular blades (14) engages a corresponding one of said grooves (60) during a working stage, the circular blades (14) being spaced from each other a distance "D" slightly greater than a distance "B" between said grooves (60) of the circular counterblades (16), said distance "D" between the circular blades (14) being equal to or slightly greater than a width "A" of the vertical side (24") of the second plate (24) of said carriage (20), whereby a transverse cut of said material (72) is obtained of such a width as to permit the passage through said material (72) of said vertical side (24") of said second plate (24).
