Abstract
Abstract A strip-shaped record carrier having two oppositely extending longitudinal margins is advanced in its direction of elongation. A pair of scribing units are located at opposite lateral sides of the carrier, and the drive is provided for moving these units in unison and in mutually opposite directions in such a manner that as one unit traverses the record carrier from one to the other margin thereof, the second unit will traverse the record carrier from the other to the one margin thereof, and the two units will reach the respectively opposite margins at the same time. The units are spaced longitudinally of the record carrier by a distance corresponding to the spacing between two consecutive lines which are to be recorded on the carrier.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
244 words
In an apparatus for producing consecutive parallel lines of indicia on a major surface of an elongated strip-shaped record carrier having edges extending in the longitudinal direction of the record carrier, a combination comprising two scribing units; means mounting said scribing units so that one of said scribing units is peRmanently spaced from the other one in said longitudinal direction of record carrier by a distance corresponding to the spacing between two consecutive lines of indicia to be produced, said mounting means being elongated and extending transversely of the record carrier and parallel to the major surface thereof, said scribing units being mounted on said mounting means for displacement longitudinally thereof between a first end position adjacent one of the edges of the record carrier and a second end position adjacent the other edge; drive means for displacing one of said scribing units between said first and second end positions thereof and for simultaneously displacing the other scribing unit between said second and first end positions thereof, and vice versa, while said scribing units are always spaced by said distance in said longitudinal direction of the record carrier; means for actuating said scribing units so as to produce a respective line of indicia at least during the displacement of the respective scribing unit between said first and second end positions thereof; and means for effecting intermittent relative displacement between the record carrier and said mounting means in said longitudinal direction of the record carrier.
Claim 2
Dependent Claim

In an apparatus for producing consecutive parallel lines of indicia on a major surface of an elongated strip-shaped record carrier having edges extending in the longitudinal direction of the record carrier, a combination comprising two scribing units; means mounting said scribing units so that one of said scribing units is peRmanently spaced from the other one in said longitudinal direction of record carrier by a distance corresponding to the spacing between two consecutive lines of indicia to be produced, said mounting means being elongated and extending transversely of the record carrier and parallel to the major surface thereof, said scribing units being mounted on said mounting means for displacement longitudinally thereof between a first end position adjacent one of the edges of the record carrier and a second end position adjacent the other edge; drive means for displacing one of said scribing units between said first and second end positions thereof and for simultaneously displacing the other scribing unit between said second and first end positions thereof, and vice versa, while said scribing units are always spaced by said distance in said longitudinal direction of the record carrier; means for actuating said scribing units so as to produce a respective line of indicia at least during the displacement of the respective scribing unit between said first and second end positions thereof; and means for effecting intermittent relative displacement between the record carrier and said mounting means in said longitudinal direction of the record carrier.
Claim 3
Dependent Claim
27 words
A combination as defined in claim 1, wherein said drive means comprises a drive arrangement common to said units and operative for moving the same in unison.
Claim 4
Dependent Claim
35 words
A combination as defined in claim 1; further comprising a pair of carriages mounted on said mounting means for movement longitudinally thereof; and wherein each of said units is carried by one of said carriages.
Claim 5
Dependent Claim
33 words
A combination as defined in claim 3, wherein said mounting means comprises at least two guide rails; and wherein each of said carriages is mounted on a different one of said guide rails.
Claim 6
Dependent Claim
44 words
A combination as defined in claim 1, wherein said drive means comprises a pair of rollers mounted adjacent the respective edges, and an elongated flexible drive element trained about said rollers and forming a closed loop, said units being connected to said drive element.
Claim 7
Dependent Claim
14 words
A combination as defined in claim 5, wherein said drive element is a rope.
Claim 8
Dependent Claim
14 words
A combination as defined in claim 5, wherein said drive element is a tape.
Claim 9
Dependent Claim
15 words
A combination as defined in claim 5, wherein said drive element is a toothed belt.
Claim 10
Dependent Claim
57 words
A combination as defined in claim 5, wherein one of said rollers is provided with a thread, said drive element further comprising a rope trained about said one roller so as to enter into said thread; and wherein said drive means further comprises a step motor connected with said one roller for driving the same in rotation.
Claim 11
Dependent Claim
31 words
A combination as defined in claim 3; and further comprising pivot means mounting said units on the respective carriages for pivotal movement into and out of contact with said record carrier.
Claim 12
Dependent Claim
48 words
A combination as defined in claim 1; and further comprising control means for moving each of said units into contact with said carrier upon the respective unit reaching said first end position, and out of contact with said carrier upon the same unit reaching said second end position.
Claim 13
Dependent Claim
67 words
A combination as defined in claim 11, wherein said units each comprise a member which is slidable between two positions in which it effects movement of said unit into and out of contact with said carrier; and wherein said control means comprises abutments provided in the regions of said edges and operative for engaging and sliding the respective member from one to the other of said positions.
