Abstract
Abstract A stripping die assembly for a stripper in an in-line flat-bed press die cutting system, is prepared for installation in the press as an assembly, and removal from the press as an assembly. Upon installation, the stripping station of the press is essentially closed to enable securing the stripping die to its stationary support, and the movable template to its support before any disassembly of the stripping die from the template. After attachment to the respective press machine stripping station members, fasteners are removed to enable separation of the stripping die from the template, in perfect alignment. Following completion of a run of die cut products, the stripping station is again closed to the stripping position. Then the stripping die and template are again secured together while still attached to the press and in perfect alignment. After being secured together, they are disconnected from the stripping station of the press and returned to storage in exact alignment with each other, ready for installation the next time pieces are needed of the same die cut pattern.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
A stripping assembly for in-line stripping apparatus of stripping stations in die cutting systems comprising: a stripping die including a generally planar mounting member and waste stripper means on said mounting member; a template including a planar member shaped to provide support for non-scrap areas of a work piece to be stripped; and fastener means retaining the mounting member and template in alignment when the assembly is separate from the stripping station of the system; said stripper means including stripper blocks secured to said template, and said fastener means including: a plurality of lock-up plates secured to said stripper means and said template; and means securing said lock-up plates to said stripper means and said template.
Claim 2
Dependent Claim
116 words
A stripping assembly for in-line stripping apparatus of stripping stations in die cutting systems comprising: a stripping die including a generally planar mounting member and waste stripper means on said mounting member; a template including a planar member shaped to provide support for non-scrap areas of a work piece to be stripped; and fastener means retaining the mounting member and template in alignment when the assembly is separate from the stripping station of the system; said stripper means including stripper blocks secured to said template, and said fastener means including: a plurality of lock-up plates secured to said stripper means and said template; and means securing said lock-up plates to said stripper means and said template.
Claim 3
Dependent Claim
73 words
The assembly of claim 1 wherein: said mounting member is a board, and said planar member of said template has a surface which faces said board, and said template includes a pair of support rails on a surface thereof on the side opposite the surface which faces said die board, said support rails having means thereon facilitating attachment thereof to support bars in a stripping station of a die cutting and stripping system.
Claim 4
Dependent Claim
97 words
A stripping assembly for in-line stripping apparatus of stripping stations in die cutting systems comprising: a stripping die including a generally planar mounting member and waste stripper means on said mounting member; a template including a planar member shaped to provide support for non-scrap areas of a work piece to be stripped; and fastener means retaining the mounting member and template in alignment when the assembly is separate from the stripping station of the system, said template being under said planar member and having a beveled edge at the underside thereof, to facilitate stripping of stock therewith.
Claim 5
Dependent Claim
97 words
A stripping assembly for in-line stripping apparatus of stripping stations in die cutting systems comprising: a stripping die including a generally planar mounting member and waste stripper means on said mounting member; a template including a planar member shaped to provide support for non-scrap areas of a work piece to be stripped; and fastener means retaining the mounting member and template in alignment when the assembly is separate from the stripping station of the system, said template being under said planar member and having a beveled edge at the underside thereof, to facilitate stripping of stock therewith.
Claim 6
Dependent Claim
17 words
The assembly of claim 3 wherein: said planar member and stripper means and template are hardwood plywood.
Claim 7
Dependent Claim
39 words
The assembly of claim 4 wherein: said fastener means include T-nuts driven into said planar member and into said template at the upper faces thereof, with the upper face of the template, including the T-nuts, being smooth and planar.
Claim 8
Dependent Claim
130 words
A stripping assembly for in-line stripping apparatus of stripping stations in die cutting systems comprising: a stripping die including a generally planar mounting member and waste stripper means on said mounting member; a template including a planar member shaped to provide support for non-scrap areas of a work piece to be stripped; and fastener means retaining the mounting member and template in alignment when the assembly is separate from the stripping station of the system, said mounting member and the planar member of the template being in vertically spaced parallel planes, the spacing of the planes while retained in secure alignment by said fasteners being no greater than the minimum spacing which would enable stripping scrap by the assembly from a die cut work piece supported on said planar member.
Claim 9
Dependent Claim
130 words
A stripping assembly for in-line stripping apparatus of stripping stations in die cutting systems comprising: a stripping die including a generally planar mounting member and waste stripper means on said mounting member; a template including a planar member shaped to provide support for non-scrap areas of a work piece to be stripped; and fastener means retaining the mounting member and template in alignment when the assembly is separate from the stripping station of the system, said mounting member and the planar member of the template being in vertically spaced parallel planes, the spacing of the planes while retained in secure alignment by said fasteners being no greater than the minimum spacing which would enable stripping scrap by the assembly from a die cut work piece supported on said planar member.
Claim 10
Dependent Claim
43 words
The assembly of claim 6 wherein: said planar member of said template has a flat top area lying in a plane, and said stripper means project from said mounting member downward through the said plane of the said top area of said template.
Claim 11
Dependent Claim
44 words
The assembly of claim 7 wherein: said template planar member shape is defined, in part, by lateral stripping edges, said stripper means projecting into the space adjacent said lateral stripping edges and leaving horizontal clearance space between said stripper means and said lateral edges.
Claim 12
Dependent Claim
37 words
The assembly of claim 8 wherein: said stripper means having lower edges, and said lateral stripping edges are beveled from a level above said lower edges of said stripping means, toward the bottom of said planar member.
