WASTE STRIPPING AND CUTTING ARRANGEMENT, CASSETTE, UNIT AND MACHINE PROVIDED THEREWITH

摘要

An arrangement for cutting off and ejecting waste from a planar support (3), includes a first rotating cylindrical tool for ejecting waste (16), the surface of which has at least one radial, waste-retaining needle, a second rotating cylindrical tool (17), first and second side bearings (26, 27), holding the first tool (16) for rotation, third and fourth side bearings (29, 31), holding the second tool (17) for rotation, and at least one ejector (39); the two tools (16, 17) and the ejector (39) cooperating to eject the waste from the support (3). The ejector (39) is fixed transversely to a lower portion of the first and second bearings (26, 27) respectively.

主权项

1. A waste stripping and cutting arrangement from a flat substrate, comprising:
a first cylindrical rotary tool for ejecting waste stripped and cut from the substrate, the first tool having a surface thereon with at least one radial needle and the needle is configured for retaining waste on the at least one needle; a second cylindrical rotary tool parallel to the first tool and defining a radial gap between the first and second tools; a first lateral bearing and a second lateral bearing holding the first tool for the purpose of rotation, the first and second tools being spaced apart along the first tool; a third lateral bearing and a fourth lateral bearing holding the second tool for the purpose of rotation, the third and fourth tools being spaced apart along the second tool; at least one ejector configured for removing waste from the at least one radial needle, the first and second tools and the ejector being arranged, configured, and cooperating with one another for the cutting of the substrate and the stripping waste produced from the substrate by the cutting and stripping; and means for joining the ejector attached transversely of the substrate and the ejector is located in a region of a lower part, respectively of the first bearing and the second bearing.
