Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
203 words
In an apparatus for automatically forming packages of printed products from a stream of said products being conveyed in a fishscale sequence, a bonding agent conveying apparatus comprising means for conveying said products in a fish-scale sequence, means for generating a regulating signal having a value which varies in accordance with the speed at which said products are being conveyed, a source of compressed air, a pressurized container for a liquid bonding agent, converter means controlled by said regulating signal and connecting the compressed air source with said pressurized container for regulating the pressure in said pressurized container in accordance with the speed at which said products are being conveyed, means proximate said conveyor for forming a regulatable spray stream of said liquid bonding agent onto said printed products, means for conveying the pressurized liquid bonding agent in said container to said liquid stream forming means, the rate of flow of said bonding agent into said liquid spray stream forming means being proportional to the pressure in said container and being substantially proportional to the speed at which said products are being conveyed, and means for forming a package of said printed products, wherein said bonding agent stabilizes said package of printed products.
Claim 2
Dependent Claim
203 words
In an apparatus for automatically forming packages of printed products from a stream of said products being conveyed in a fishscale sequence, a bonding agent conveying apparatus comprising means for conveying said products in a fish-scale sequence, means for generating a regulating signal having a value which varies in accordance with the speed at which said products are being conveyed, a source of compressed air, a pressurized container for a liquid bonding agent, converter means controlled by said regulating signal and connecting the compressed air source with said pressurized container for regulating the pressure in said pressurized container in accordance with the speed at which said products are being conveyed, means proximate said conveyor for forming a regulatable spray stream of said liquid bonding agent onto said printed products, means for conveying the pressurized liquid bonding agent in said container to said liquid stream forming means, the rate of flow of said bonding agent into said liquid spray stream forming means being proportional to the pressure in said container and being substantially proportional to the speed at which said products are being conveyed, and means for forming a package of said printed products, wherein said bonding agent stabilizes said package of printed products.
Claim 3
Dependent Claim
67 words
The apparatus of claim 1 wherein said means for forming a regulatable stream of said bonding agent includes a spray nozzle, an electromagnetic valve means for controlling said spray nozzle, and scanner means responsive to the infeed of a fish-scale product stream into the path of the stream of bonding agent for releasing the spray nozzle to discharge a stream of bonding agent toward said product stream.
Claim 4
Dependent Claim
34 words
The apparatus as defined in claim 2, further comprising a second scanner means arranged upstream with respect to said first scanner means, said scanner means providing a signal for actuating said electromagnetic valve means.
Claim 5
Dependent Claim
42 words
The apparatus as defined in claim 3, further including a control circuit for the electro-magnetic valve, and a time-delay circuit means arranged in the control circuit of the electro-magnetic valve, said time-delay circuit means being adjusted or adjustable to a predetermined value.
