Abstract
Abstract A method of producing plate-like supports on which frequencies are recorded, and having an impressed surface, comprises the successive pressing of fractional areas of a support in chronological sequence. The supports may be records applied in succession onto one strip of the pressed material and subsequently stamped out individually from the strip or cut out therefrom with fractional and rectangular surrounding areas of the strip. A device for carrying out the method comprises two parallel cylinders rotatably mounted in a machine frame, at least one of which can be driven and is adapted to receive impressionapplying dies for pressing the strip surface. The strip is fed between the cylinders and comprises a surface layer capable of taking the impression and a supporting layer of a different material. When both sides of the strip are to be impressed two such surface layers are provided with an intermediate supporting layer sandwiched between them.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
261 words
A device for the continuous high speed production of foil records having an impressed surface on which frequencies are recorded comprising, in combination, a machine frame, foil strip treating means mounted on said machine frame defining a path of movement for sequential treatment of foil strip, a dispenser dispensing foil strip into said treating means, said treating means comprising, in succession, with respect to the direction of said path of foil strip movement, a pair of rotatably driven traction rollers mounted on said frame receiving said foil strip therebetween from said dispenser, heating means defined on said machine frame receiving said foil strip and heating said strip to an impression receiving temperature, a pressing cylinder rotatably and drivably mounted on said machine frame receiving foil strip from said heating means and bearing impressionapplying dies for pressing said records, a second cylinder rotatably mounted on said machine frame with its axis parallel with the axis of said pressing cylinder cooperating with said cylinder to exert a counter-pressure on said foil strip as it passes between said cylinders, a pair of parallel, opposed, cooling rollers rotatably mounted on said machine frame receiving said foil strip therebetween from said cylinders cooling said strip, a pair of parallel opposed, advancing rollers rotatably mounted on said machine frame receiving said foil strip therebetween advancing said strip to separating means, and rotatable separating means mounted on said machine frame receiving foil strip from said advancing rollers rotating in synchronization with said pressing cylinder for separating predetermined areas defined on said foil strip each containing a record impression.
Claim 2
Independent Claim

A device for the continuous high speed production of foil records having an impressed surface on which frequencies are recorded comprising, in combination, a machine frame, foil strip treating means mounted on said machine frame defining a path of movement for sequential treatment of foil strip, a dispenser dispensing foil strip into said treating means, said treating means comprising, in succession, with respect to the direction of said path of foil strip movement, a pair of rotatably driven traction rollers mounted on said frame receiving said foil strip therebetween from said dispenser, heating means defined on said machine frame receiving said foil strip and heating said strip to an impression receiving temperature, a pressing cylinder rotatably and drivably mounted on said machine frame receiving foil strip from said heating means and bearing impressionapplying dies for pressing said records, a second cylinder rotatably mounted on said machine frame with its axis parallel with the axis of said pressing cylinder cooperating with said cylinder to exert a counter-pressure on said foil strip as it passes between said cylinders, a pair of parallel, opposed, cooling rollers rotatably mounted on said machine frame receiving said foil strip therebetween from said cylinders cooling said strip, a pair of parallel opposed, advancing rollers rotatably mounted on said machine frame receiving said foil strip therebetween advancing said strip to separating means, and rotatable separating means mounted on said machine frame receiving foil strip from said advancing rollers rotating in synchronization with said pressing cylinder for separating predetermined areas defined on said foil strip each containing a record impression.
Claim 3
Dependent Claim
32 words
A device for the continuous high speed production of foil records as in claim 1 wherein said heating means comprises a pair of parallel opposed rollers rotatably mounted on said machine frame.
Claim 4
Dependent Claim
61 words
A device for the continuous high speed production of foil records as in claim 1, printing means comprising at least one pair of parallel, opposed, printing rollers rotatably mounted on said machine frame located between said cooling rollers and said advancing rollers and receiving said foil strip therebetween printing said foil prior to separation of said predetermined areas from said strip.
Claim 5
Dependent Claim
68 words
A device for the continuous high speed production of foil records as in claim 3, wherein said printing means comprises two sets of pairs of parallel, opposed printing rollers rotatably mounted on said machine frame, said foil strip being received between the rollers of each pair, one of said pairs printing said foil strip on one side thereof, and the other pair printing the opposite foil strip side.
