Abstract
Abstract Punched and printed cards are produced in large groups by severing and simultaneous punching of printed plastic sheets in such a way that each card continues to adhere to but is readily separable from the remainder of the sheet. The apparatus for the punching and severing of sheets has two relatively movable sections one of which supports a sheet and the other of which can be moved against the sheet by the ram of a press. The sections have cooperating cutting edges which effect nearly complete separation of cards and one of the sections carries punches which can be forced through the sheet to form punch holes by motion transmitting pins or balls which are shifted in response to closing of the press. The pins or balls are inserted into the one section in accordance with a selected program, such as by copying the distribution of holes in a punched tape which is employed for precoding of the apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
In an apparatus for the production of punched cards from sheets, particularly for the production of cards for use in data transmission, a combination comprising a sheet-supporting first section having a plurality of coplanar apertured anvils each provided with first cutting edges distributed in conformance with the outline of a card and a base fixedly supporting said anvils; a second section arranged to overlap a sheet which is supported by said first section and including an encoding member provided with second cutting edges complementary to said first cutting edges; and means for moving one of said sections toward the other section so that said first and second cutting edges cooperate to sever the sheet between said sections and to thus form in the sheet a plurality of cards, said first and second cutting edges having major portions which cooperate to cut through a sheet between said sections and minor portions which cooperate to weaken the portions of a sheet therebetween so that each of the simultaneously formed cards continues to adhere to the remainder of the sheet, said major portions of said cutting edges on each of said anvils forming rectangles and said minor portions of said first cutting edges extending obliquely at the corners of the respective rectangle.
Claim 2

In an apparatus for the production of punched cards from sheets, particularly for the production of cards for use in data transmission, a combination comprising a sheet-supporting first section having a plurality of coplanar apertured anvils each provided with first cutting edges distributed in conformance with the outline of a card and a base fixedly supporting said anvils; a second section arranged to overlap a sheet which is supported by said first section and including an encoding member provided with second cutting edges complementary to said first cutting edges; and means for moving one of said sections toward the other section so that said first and second cutting edges cooperate to sever the sheet between said sections and to thus form in the sheet a plurality of cards, said first and second cutting edges having major portions which cooperate to cut through a sheet between said sections and minor portions which cooperate to weaken the portions of a sheet therebetween so that each of the simultaneously formed cards continues to adhere to the remainder of the sheet, said major portions of said cutting edges on each of said anvils forming rectangles and said minor portions of said first cutting edges extending obliquely at the corners of the respective rectangle.
Claim 3
Dependent Claim
33 words
A combination as defined in claim 1, wherein said encoding member has a plurality of recesses each in register with one of said anvils and said second cutting edges surround the respective recesses.
Claim 4
Dependent Claim
100 words
A combination as defined in claim 2, wherein said second section further comprises apertured inserts movably received in the recesses of said encoding member, punches movably received in the apertures of said inserts, motion transmitting elements received in selected ones of apertures provided in said encoding member in alignment with the apertures of said inserts, and means for propelling the punches through the material of a sheet between said sections by way of said motion transmitting elements in response to movement of said one section toward said other section whereby the thus propelled punches cut holes into the corresponding cards.
Claim 5
Dependent Claim
24 words
A combination as defined in claim 3, wherein the means for propelling the punches comprises a cover mEmber separably secured to said encoding member.
Claim 6
Dependent Claim
