Abstract
Various embodiments of a perforator are disclosed.
Claims30
A perforator comprising:
- a first and second rotatable members;
- a first anvil coupled to the first rotatable member, the first anvil having one or more apertures;
- a first blade coupled to the second rotatable member, the first blade having one or more protrusions to perforate a sheet of media;
- and
- a media feed configured to drive the sheet of media between and relative to both the first rotatable member and the second rotatable member such that the first blade may engage media against the first anvil at a continuum of locations along the media.
2 more elements
A perforator component comprising:
- a rotatable member;
- anvils consecutively coupled to the rotatable member;
- and
- blades consecutively coupled to the rotatable member, at least two of the blades having discreet teeth to perforate media.
1 more element
A perforator component comprising:
- a rotatable member extending along an axis and having a first substantially planar face extending along the axis;
- an anvil coupled to the rotatable member;
- and
- a blade coupled to the rotatable member, wherein the first substantially planar face extends between the anvil and the blade.
1 more element
A perforator component comprising:
- a rotatable member including a cavity;
- and
- an anvil having an elastomeric blade-engaging portion opposite the cavity, wherein the anvil is configured to form into the cavity when in engagement with a blade.
A perforator component comprising:
- a first rotatable member supporting an anvil;
- a second rotatable member supporting a blade, the blade having discrete cutters to perforate media;
- and
- means for moving media between and relative to both the first rotatable member and the second rotatable member such that the first blade may engage media against the first anvil at a continuum of locations along the media.
1 more element
A method comprising:
- moving a medium between and relative to both a first rotatable member supporting a first structure and a second rotatable member supporting a first blade to selectively position one of a continuum of portions of the medium relative to the first structure and the first blade;
- and
- perforating the medium between the first structure and the first blade.
