Abstract
Abstract Apparatus for making dies for rotary cutting cylinders which is portable and has spaced circular mounting heads upon which a die board can be mounted for scribing, drilling, cutting, etc. One of the die heads carries a true measurement scale about its circumference, the scale being annular and concentric with the mounting die board, and spaced from the outer cylindrical surface of the die board a distance equal to the proposed projection of the cutting rules from the board surface when mounted. A tool holder is mounted on a graduated indexing bar for movement longitudinally of the cylinder, and has a tool opening having its axis radial to the cylinder. There is an index pointer over the circumferential scale on the mounting head having its point in a plane radial to the cylinder which includes the tool opening axis. This allows true measurement scales to be used throughout and the points of contact of a tool in the tool holder with the die board to form a proper circumferentially shrunken image of the article which the completed die is to cut.

Claim 1
Independent Claim
223 words
Apparatus for making dies for rotary cutting cylinders, which dies have cylindrically curved mounting boards with cutting rules fixed thereto and projecting therefrom to outline the article to be cut, the apparatus comprising, a frame, a shaft carried by the frame, a pair of mounting heads rotatably carried by the shaft in spaced axial alignment, each mounting head having a cylindrical surface upon which the ends of die boards for making mounting boards are supported, one of said heads having an annular flange coaxial with the head and extending beyond the said cylindrical surface a distance equal to the thickness of the die board plus the proposed projection of the cutting rules beyond the board, a circumferential indexing scale about the circumference of the annular flange, an indexing bar carred by support arms extending from said frame, an indexing pointer carried by means maintaining the indexing plus the proposed projection of the cutting rules beyond the board, a circumferential indexing scale about the circumference of the annular flange, an indexing bar carred by support arms extending from said frame, an indexing pointer carried by means maintaining the indexing pointer in fixed relationship to said indexing bar and overlying the scale, and a tool holder carried by said indexing bar and having a tool axis which lies in a plane radial to the shaft.

Claim 3
Dependent Claim
27 words
Apparatus for making dies as claimed in claim 1 wherein, the indexing pointer lies in the radial plane which includes the tool axis of the tool holder.
Claim 4
Dependent Claim
41 words
Apparatus for making dies as claimed in claim 1 wherein, said indexing bar includes a scale carried by the frame bridging the spaced mounting heads, and the tool holder is mounted for longitudinal movement along the length of said indexing bar.
Claim 5
Dependent Claim
40 words
Apparatus for making dies as claimed in claim 3 wherein, one of the mounting heads is fixed to the shaft and the other mounting head is movable along the shaft to adjusted positions toward and from the fixed mounting head.
Claim 6
Dependent Claim
27 words
Apparatus for making dies as claimed in claim 4 wherein, the indexing pointer lies in the radial plane which includes the tool axis of the tool holder.
Claim 7
Dependent Claim
38 words
Apparatus for making dies as claimed in claim 5 wherein, the longitudinal indexing bar extends along the frame at one side of the vertical center of the mounting heads to leave the top of the die board unobstructed.
Claim 8
Dependent Claim
28 words
Apparatus for making dies as claimed in claim 6 wherein, the tool holder has means to fix the holder in positions of adjustment along the longitudinal indexing bar.
Claim 9
Dependent Claim
33 words
Apparatus as claimed in claim 7 wherein, the tool holder has means to releasably support a tool with the operating axis of the tool coinciding with the tool axis of the tool holder.
