Abstract
Abstract A machine for manufacturing disc records. The machine has a molding station where records are molded, a trimming station where flash is trimmed from the molded records, and a receiving station where finished records are received. A transfer assembly simultaneously transfers the molded records from the molding station to the trimming station and the finished records from the trimming station to the receiving station. At the receiving station envelopes are automatically situated in a condition for receiving the finished records so that the finished records are automatically placed in envelopes.

Claim 1
Independent Claim
437 words
In a machine for manufacturing disc records, molding means situated at a molding station for molding records with flash projecting circumferentially therefrom, trimming means situated at a trimming station for trimming flash from a molded record, receiving means situated at a receiving station for receiving a finished record from which the flash has already been trimmed by said trimming means, and transfer means movable between said stations for transferring a mOlded record from said molding station to said trimming station and for simultaneously transferring a trimmed record from said trimming station to said receiving station, guide means coacting with said transfer means for guiding the latter in one direction along a working stroke during which said transfer means transfers a record from said molding station to said trimming station and a trimmed record from said trimming station to said receiving station, and said guide means guiding said transfer means for movement in an opposite direction along a return stroke back to a starting position for receiving the next molded record and the next trimmed record, said trimming means including a support for receiving a record transferred from said molding station to said trimming station by said transfer means, said trimming means also including a circular trimming die for acting on a record on said support for trimming flash therefrom during movement of said trimming die with respect to said support, said transfer means having a first flash-engaging means for engaging flash extending circumferentially from a molded record at said molding station to support the molded record during transfer thereof from said molding station to said trimming station, and said transfer means also having a second flash-engaging means for engaging a ring of trimmed flash trimmed from a record at said trimming station by said circular trimming die, said transfer means coacting with said trimming means at said trimming station for receiving with said second flash-engaging means the ring of flash trimmed from a record for removing the trimmed flash from said trimming station, said first flash-engaging means releasing a molded record at said trimming station at the end of said working stroke and said second flash-engaging means releasing the trimmed ring of flash after removal thereof from the trimming station during movement of said transfer means along said working stroke, and both of said flash-engaging means returning with said transfer means along the return stroke thereof for respectively engaging the flash circumferentially projecting from the next molded record at the molding station and the ring of flash trimmed from the next molded record delivered at the trimming station during the previous working stroke of said transfer means.
Claim 2
Dependent Claim
437 words
In a machine for manufacturing disc records, molding means situated at a molding station for molding records with flash projecting circumferentially therefrom, trimming means situated at a trimming station for trimming flash from a molded record, receiving means situated at a receiving station for receiving a finished record from which the flash has already been trimmed by said trimming means, and transfer means movable between said stations for transferring a mOlded record from said molding station to said trimming station and for simultaneously transferring a trimmed record from said trimming station to said receiving station, guide means coacting with said transfer means for guiding the latter in one direction along a working stroke during which said transfer means transfers a record from said molding station to said trimming station and a trimmed record from said trimming station to said receiving station, and said guide means guiding said transfer means for movement in an opposite direction along a return stroke back to a starting position for receiving the next molded record and the next trimmed record, said trimming means including a support for receiving a record transferred from said molding station to said trimming station by said transfer means, said trimming means also including a circular trimming die for acting on a record on said support for trimming flash therefrom during movement of said trimming die with respect to said support, said transfer means having a first flash-engaging means for engaging flash extending circumferentially from a molded record at said molding station to support the molded record during transfer thereof from said molding station to said trimming station, and said transfer means also having a second flash-engaging means for engaging a ring of trimmed flash trimmed from a record at said trimming station by said circular trimming die, said transfer means coacting with said trimming means at said trimming station for receiving with said second flash-engaging means the ring of flash trimmed from a record for removing the trimmed flash from said trimming station, said first flash-engaging means releasing a molded record at said trimming station at the end of said working stroke and said second flash-engaging means releasing the trimmed ring of flash after removal thereof from the trimming station during movement of said transfer means along said working stroke, and both of said flash-engaging means returning with said transfer means along the return stroke thereof for respectively engaging the flash circumferentially projecting from the next molded record at the molding station and the ring of flash trimmed from the next molded record delivered at the trimming station during the previous working stroke of said transfer means.
Claim 3
Dependent Claim
73 words
The combination of claim 1 and wherein an envelope supply means is located at said receiving station for supplying thereto envelopes for respectively receiving finished records, said supply means operating on envelopes at said receiving station for supplying the envelopes one after the other in an open condition for automatically receiving records successively delivered to said receiving station by said transfer means so that each completed record is automatically situated in an envelope.
Claim 4
Dependent Claim
