Abstract
Abstract A continuous web for library catalogue cards having a plurality of slit lines longitudinally spaced 7.5 centimeters apart, each slit line extending 12.5 centimeters transversely between edge carrier portions of the form such that upon removal of the carrier portions outwardly of the slit lines a plurality of standard 7.5 centimeters × 12.5 centimeters catalogue cards are provided. Longitudinally extending lines of uniquely shaped feed holes or perforations are provided in the carrier portions of the form which permit printing of the cards by means of existing high speed printers of United States manufacture despite the cards being dimensioned in the metric system and the feed of the printers being dimensioned in the English system.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
The method of feeding a continuous web, marginally punched, metrically dimensioned form on a machine having an endless array of driven feed pins with a 1/2 inch spacing between pins, comprising the steps of: engaging the feed pins with a form having at least one margin with feed perforations having a center-to-center spacing of 1.25 centimeters, with the perforations being elongated in the longitudinal direction of feed to provide a longitudinal perforation dimension substantially greater than the transverse perforation dimension; engaging one perforation driving edge with one feed pin; driving the one feed pin and thereby the continuous length web material in the driving direction; thereafter releasing the one feed pin from its driving engagement with the one perforation driving edge; thereafter moving the feed pins approximately 0.02 centimeters while simultaneously holding said continuous web stationary; thereafter engaging the next feed pin with the corresponding next feed perforation driving edge and advancing said next feed pin and continuous length web approximately 1.25 centimeters; and thereafter indefinitely repeating the above three preceding steps for successive feed pins and feed perforations.
Claim 2
Independent Claim
179 words
The method of feeding a continuous web, marginally punched, metrically dimensioned form on a machine having an endless array of driven feed pins with a 1/2 inch spacing between pins, comprising the steps of: engaging the feed pins with a form having at least one margin with feed perforations having a center-to-center spacing of 1.25 centimeters, with the perforations being elongated in the longitudinal direction of feed to provide a longitudinal perforation dimension substantially greater than the transverse perforation dimension; engaging one perforation driving edge with one feed pin; driving the one feed pin and thereby the continuous length web material in the driving direction; thereafter releasing the one feed pin from its driving engagement with the one perforation driving edge; thereafter moving the feed pins approximately 0.02 centimeters while simultaneously holding said continuous web stationary; thereafter engaging the next feed pin with the corresponding next feed perforation driving edge and advancing said next feed pin and continuous length web approximately 1.25 centimeters; and thereafter indefinitely repeating the above three preceding steps for successive feed pins and feed perforations.
Claim 3
Dependent Claim
39 words
The method of claim 1, including the step of providing said elongated perforations as rectangles 5/16 inch long and 5/32 inch wide with rounded ends and providing said feed pins with a diameter within said perforations of 1/8 inch.
Claim 4
Independent Claim
169 words
The method of feeding a continuous web, marginally punched, metrically dimensioned form on a machine having an endless array of driven feed pins with a one-half inch spacing between pins, comprising the steps of: providing a form having at least one margin with spaced feed perforations, the perforations being elongated in the longitudinal direction of feed to provide a longitudinal perforation dimension substantially greater than the transverse perforation dimension and substantially greater than the pin longitudinal dimension; engaging one perforation driving edge with one feed pin; driving the one feed pin and thereby the continuous length web material in the driving direction; thereafter releasing the one feed pin from its driving engagement with the one perforation driving edge; thereafter moving the feed pins to engage the next feed pin with the corresponding next feed perforation driving edge while simultaneously holding continuous web stationary; thereafter advancing said next feed pin and continuous length web; and thereafter indefinitely repeating the above three preceding steps for successive pin feeds and feed perforations.
Claim 5
Independent Claim
169 words
The method of feeding a continuous web, marginally punched, metrically dimensioned form on a machine having an endless array of driven feed pins with a one-half inch spacing between pins, comprising the steps of: providing a form having at least one margin with spaced feed perforations, the perforations being elongated in the longitudinal direction of feed to provide a longitudinal perforation dimension substantially greater than the transverse perforation dimension and substantially greater than the pin longitudinal dimension; engaging one perforation driving edge with one feed pin; driving the one feed pin and thereby the continuous length web material in the driving direction; thereafter releasing the one feed pin from its driving engagement with the one perforation driving edge; thereafter moving the feed pins to engage the next feed pin with the corresponding next feed perforation driving edge while simultaneously holding continuous web stationary; thereafter advancing said next feed pin and continuous length web; and thereafter indefinitely repeating the above three preceding steps for successive pin feeds and feed perforations.
Claim 6
Dependent Claim
21 words
The method of claim 3, including the step of providing said elongated perforations with a longitudinal, center-to-center spacing of 1.25 centimeters.
