Cutting mat for a rotary anvil
View Patent ↗A rotary anvil is outfitted with pins protruding from the base of an axially extending channel along the surface of the anvil. A cutting mat having a generally elongate body includes first and second locking members projecting from opposite axial ends thereof. The cutting mat is installed on the anvil such that the first and second locking members are positioned within the channel over one of the pins. The cutting mat may include a foot extending from the first locking member that includes a pin receptacle that seats down over the pin. Alternatively, a lockup device may be provided to temporarily secure the cutting mat to the rotary anvil. The lockup device includes a pin receptacle on the bottom surface thereof adapted to seat down over the pin. The first and second locking members of the cutting mat are then installed into the channel in cooperation with the lockup device.
1. A cutting mat and lockup system for use with a rotary anvil comprising:
a cutting mat having:
a generally elongate body;
opposing, complimentary and nonlinear first and second axial edges;
a first end portion proximate to said first axial edge having a first locking member comprising a first face, at least a portion of which is nonlinear in an axial direction;
a second end portion proximate to said second axial edge having a second locking member comprising a second face that is generally complimentary to said first face; and
a lockup device comprising:
a base having first and second axial edges, and a pin receptacle dimensioned to position over a pin projecting from a channel of said rotary anvil;
a sidewall projecting from said first axial edge of said base; and,
a locking wedge projecting from said base defining a first locking area between said sidewall and said locking wedge and a second locking area between said locking wedge and said second axial edge of said base; wherein:
said lockup device is installable into a channel of a rotary anvil such that said in receptacle is received by a in protruding from said channel and said cutting mat is installable into said lockup device such that said first locking member is received by said first locking area, said second locking member is received by said second locking area, said first and second faces abut in mating relationship and said first and second axial edges define a nonlinear seam therebetween; and wherein said base of said lockup device further comprises a slot and said second locking member comprises a post projecting therefrom, said slot and post oriented such that when said cutting mat and said lockup device are installed in said channel of said rotary anvil, said post seats down into said slot.
2. The cutting mat and lockup system according to claim 1 , wherein said slot extends inwardly from said second axial edge of said base.
3. The cutting mat and lockup system according to claim 1 , wherein said slot extends entirely through said base.
4. A cutting mat and lockup system for use with a rotary anvil comprising:
a cutting mat having:
a generally elongate body;
opposing, complimentary and nonlinear first and second axial edges;
a first end portion proximate to said first axial edge having a first locking member comprising a first face, at least a portion of which is nonlinear in an axial direction;
a second end portion proximate to said second axial edge having a second locking member comprising a second face that is generally complimentary to said first face; and
a lockup device comprising:
a base having first and second axial edges, and a pin receptacle dimensioned to position over a pin projecting from a channel of said rotary anvil;
a sidewall projecting from said first axial edge of said base; and,
a locking wedge projecting from said base defining a first locking area between said sidewall and said locking wedge and a second locking area between said locking wedge and said second axial edge of said base; wherein:
said lockup device is installable into a channel of a rotary anvil such that said in receptacle is received by a in protruding from said channel and said cutting mat is installable into said lockup device such that said first locking member is received by said first locking area, said second locking member is received by said second locking area, said first and second faces abut in mating relationship and said first and second axial edges define a nonlinear seam therebetween; and wherein said base of said lockup device further comprises a plurality of slots and said second locking member comprises a corresponding plurality of posts projecting therefrom, said plurality of slots and said plurality of posts oriented such that when said cutting mat and lockup device are installed in said channel of said rotary anvil, each of said plurality of posts seats down in a corresponding one of said plurality of slots.
5. A cutting mat and lockup system for use with a rotary anvil having an axially extending channel along the surface thereof, said cutting mat and lockup system comprising:
a cutting mat having:
a generally elongate body;
opposing, complimentary and nonlinear first and second axial edges;
a first end portion proximate to said first axial edge having a first locking member comprising a first post projecting therefrom, and a first face, at least a portion of which is nonlinear in an axial direction;
a second end portion proximate to said second axial edge having a second locking member comprising a second face that is generally complimentary to said first face; and
a lockup device comprising:
a base having first and second axial edges, and a first slot at least partially therethrough, and a pin receptacle dimensioned to position over a pin projecting from a channel of said rotary anvil;
a sidewall projecting from said first axial edge of said base; and,
a locking wedge projecting from said base defining a first locking area between said sidewall and said locking wedge and a second locking area between said locking wedge and said second axial edge of said base; wherein:
said lockup device is installable into said channel of said rotary anvil such that said pin receptacle is received by a pin protruding from said channel and said cutting mat is installable into said lockup device such that said first locking member is received by said first locking area, said second locking member is received by said second locking area, said first and second faces abut in mating relationship, said first post on said second locking member of said cutting mat seats down into said first slot of said lockup device, and said first and second axial edges define nonlinear seam therebetween.
6. The cutting mat and lockup system according to claim 5 , wherein said first slot in said lockup device is recessed inwardly of said second axial edge of said base.
7. The cutting mat and lockup system according to claim 5 , wherein said pin receptacle comprises a through hole in said base of said lockup device.
8. The cutting mat and lockup system according to claim 5 , wherein said pin receptacle comprises a cavity in a bottom surface of said base of said lockup device.
9. The cutting mat and lockup system according to claim 5 , wherein said base of said lockup device comprises at least one additional slot and said second locking member comprises a corresponding number of additional posts such that when said lockup device and said first and second locking members are positioned within said channel, each post seats down into an associated slot.
