Abstract
Abstract In record producing apparatus a biscuit mold is formed in upper and lower complemental cup parts with fragmental rims which, on lowering the upper cup part onto the lower cup part for closing the mold cavity to form a biscuit therein, complement each other peripherally to form an uninterrupted annular rim, so that on raising the upper cup part from the lower cup part in opening the mold, the mold cavity is opened not only at the bottom but also at the top for direct exposure of a good part of a formed biscuit to the cooling effect of external air. Further in record producing apparatus, a rotary top disc is lowered and pressed against a molded record on a turntable at a trimming station to participate in the friction drive of the record during trimoff of its peripheral flash, and this top disc is also called upon to transfer a trimmed record from the trimming station to a stacking station at which to release the record for its drop onto a stacking spindle, with the top disc being to this end provided with a mechanical record holder which on the rise of the top disc from the turntable lifts the trimmed record from the latter and holds it below and spaced from the bottom face of the top disc until the latter reaches the end of its record transfer movement to the stacking station. Thus, static electricity generated in the top disc during the friction drive of the record manifests itself as characteristic attraction between top disc and record which, however, fails to be a disturbing factor in stacking the record on the designated spindle at the stacking station because of the deliberate break-up of this attraction on the separation of the record from the bottom face of the top disc when the record holder assumes the hold of the record.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
511 words
In record producing apparatus, the combination of a turntable at a first station having a vertical axis and a center pin and being adapted to receive a pressed record with peripheral flash and a center hole located on said center pin; a top disc at said first station having a bottom face and being rotary about a vertical axis in line with said turnable axis and movable axially into upper and lower positions in which its bottom face is retracted from and pressed against a record on said turntable, respectively, with said turntable and top disc constituting companion drive elements of which one is power-driven for the friction drive of a record pressed between said elements; means at said first station operative to trim the flash from a record on its friction drive to leave the trimmed record with a uniform peripheral margin outside the turntable periphery; a stacker at a second station; and means to transfer a trimmed record from said turntable to said stacker, including said top disc, and further providing a carriage mounting said top disc for said rotation and axial movement thereof, and being guided for movement into first and second positions in which said top disc is at said first and second stations, respectively, a record holder providing a carrier mounted on and movable with said top disc but independently turntable about said disc axis, a spline connection between said carriage and carrier to hold the latter against rotation in any axial position of said top disc, hangers having bottom ledges and being supported on said carrier for movement into record support and release positions in which said bottom ledges are, in relation to said top disc in said lower position at said first station, outside the outer periphery of said turntable and spaced below, but in vertical alignment with, peripheral portions of said peripheral margin of a trimmed record on the turntable, and outside the peripheral flash of a pressed record on the turntable, respectively, with said spacing of said bottom ledges of the hangers below said peripheral margin of a trimmed record on the turntable being such that the ensuing gap between the resting record on the bottom ledges and the bottom face of the top disc on its rise into said upper position is sufficient to interrupt any attraction between top disc and record due to static electricity generated in the top disc on the friction drive of the record, and means operative to shift said hangers simultaneously into said support and release positions, respectively, whereby on the rise of the top disc at said first station from said lower position the bottom ledges on the hangers in their record support positions lift a trimmed record from the turntable and support it on continued rise of the top disc to said upper position and during movement of said carriage from said first position into said second position in which the supported record is above and in receiving alignment with said stacker for its drop thereon on shifting said hangers to said release positions.
Claim 2
Dependent Claim
511 words
In record producing apparatus, the combination of a turntable at a first station having a vertical axis and a center pin and being adapted to receive a pressed record with peripheral flash and a center hole located on said center pin; a top disc at said first station having a bottom face and being rotary about a vertical axis in line with said turnable axis and movable axially into upper and lower positions in which its bottom face is retracted from and pressed against a record on said turntable, respectively, with said turntable and top disc constituting companion drive elements of which one is power-driven for the friction drive of a record pressed between said elements; means at said first station operative to trim the flash from a record on its friction drive to leave the trimmed record with a uniform peripheral margin outside the turntable periphery; a stacker at a second station; and means to transfer a trimmed record from said turntable to said stacker, including said top disc, and further providing a carriage mounting said top disc for said rotation and axial movement thereof, and being guided for movement into first and second positions in which said top disc is at said first and second stations, respectively, a record holder providing a carrier mounted on and movable with said top disc but independently turntable about said disc axis, a spline connection between said carriage and carrier to hold the latter against rotation in any axial position of said top disc, hangers having bottom ledges and being supported on said carrier for movement into record support and release positions in which said bottom ledges are, in relation to said top disc in said lower position at said first station, outside the outer periphery of said turntable and spaced below, but in vertical alignment with, peripheral portions of said peripheral margin of a trimmed record on the turntable, and outside the peripheral flash of a pressed record on the turntable, respectively, with said spacing of said bottom ledges of the hangers below said peripheral margin of a trimmed record on the turntable being such that the ensuing gap between the resting record on the bottom ledges and the bottom face of the top disc on its rise into said upper position is sufficient to interrupt any attraction between top disc and record due to static electricity generated in the top disc on the friction drive of the record, and means operative to shift said hangers simultaneously into said support and release positions, respectively, whereby on the rise of the top disc at said first station from said lower position the bottom ledges on the hangers in their record support positions lift a trimmed record from the turntable and support it on continued rise of the top disc to said upper position and during movement of said carriage from said first position into said second position in which the supported record is above and in receiving alignment with said stacker for its drop thereon on shifting said hangers to said release positions.
Claim 3
Dependent Claim
45 words
The combination in record producing apparatus as in claim 1, in which said stacker is a vertical spindle, and in said second carriage position said supported record is in receiving alignment with said stacker by being with its center hole vertically aligned with said spindle.
Claim 4
Dependent Claim
54 words
The combination in record producing apparatus as in claim 1, which further provides spring-urged plungers in said top disc urging a record away from the bottom face thereof and into seating engagement with said bottom ledges in said record support positions of said hangers on the rise of said top disc from the turntable.
Claim 5
Dependent Claim
37 words
The combination in record producing apparatus as in claim 1, in which said hangers are above their bottom ledges pivoted to said carrier about horizontal axes for their turning movement into said record support and release positions.
